At C & M Coolroom Services we believe that your freezers and coolrooms need not only be professionally constructed, but completely safe and risk-averse. While most people take large walk-in freezers for granted, we understand that these are expensive projects that require several layers of planning followed by several more layers of safety checks and health standard testing. Today, we are going to talk a little bit about Coolroom and Freezer construction as well as why it is absolutely imperative that your project meets the health and safety standards that are expected of you.

Health Standards for Coolroom and Freezer Construction

Whether you are running a grocery store or a restaurant, being able to properly cool, chill and freeze your product is of the utmost importance. Of course, this does not preclude people from trying to take shortcuts and/or hedge their bets with a sub-par product. With that being said, having a high-quality coolroom or freezer that meets all health standards is absolutely necessary. Let’s talk about those standards and what you can do in order to make sure that your coolroom or freezer meets them.

At C&M Coolroom Services, we focus on providing you a custom built and custom designed coolroom/freezer. With our construction, we focus on meeting all of the health standards that are imperative to keep your business running. A few of the health standards we focus on include:

1. Vermin Control
2. Temperature Control
3. Specialised Sealant
4. Continuous Lamination

During the construction process, after you have designed your freezer and had your quote written up, we focus on several important construction aspects. All of our panels are covered with industry strength silicon sealants which helps to keep your freezer insulated and free from temperature and humidity fluctuations. The lamination process we pointed out above helps to bond to your panel, thus giving you easy-to-clean surfaces that are far healthier and safer for your walk-in coolroom or freezer. These specialised panels also help to provide you with a bacteria and mould resistant surface which prevents you from having to turn to protective painting.

After our construction is done, there are several other health standards that need to be met. For cold rooms such as the ones we’ve been describing, you need to have several other factors going in your favour. Those factors include the ability to open the door from the inside, a way to communicate through the door, as well as complete temperature control.

A fully sealed freezer equals an energy efficient appliance, especially when that appliance assumes gigantic proportions. Furthermore, this threshold gasket stops the refrigeration unit from aging then failing in a wheeze of worn components. It’s strange how this often ignored enclosure cushioning can make such a big difference, but it really does. Regarded as an important part of the freezer system, door seals are built to conserve energy.

Rising Above Conventional Reasoning 

What knee-jerk line of reasoning spins the wheels of the average mind here? There’s the notion that a substandard gasket will warp or wear. That damage will then cause a gap to form, which means the freezer envelope is compromised. Okay, there’s nothing wrong with that reasoning, but it is a little short-sighted. Think of the domino effect, the fact that this poorly installed or poorly manufactured lining is generating a number of ensuing issues. Chief among them, the compressor is bending over backwards to balance the leak.

It’s a Slippery Slope 

What’s been proven thus far? The ‘bad’ door gasket on this hypothetical freezer isn’t performing at its best. If the elastomeric material doesn’t spring back into position after numerous door closures, the flexible lining is starting to look a little ragged around the edges. A leak develops, energy efficiency figures take a hit, and the problem worsens. The thermostat is still set at a desired subzero temperature, right? In all probability, the refrigeration unit will pull the interior temperature low, perhaps even as low as the frosty level marked on the thermostat. More than likely, though, the compressor inside that powered unit will be forced to run continuously. That always-on electrical box is certainly going to guzzle electrical kilowatts.

Detecting Less Obvious Door Seal Problems 

It’s worth noting the way different rubbers react to thermal extremes. So far, the issues mentioned here have described situations where the door gasket becomes battered and warped. Sometimes, however, tiny cracks spread across the rubber. The elastomer losses its stretchy properties because of the cold temperature. The nearly invisible fractures leak energy, but the employees point their accusing fingers at the innocent refrigeration appliance or the wall insulating panels. Fortunately, a seasoned refrigeration technician knows better, because this individual will always check this high-impact threshold point for such hidden flaws.

Just like the energy wasted by a poorly performing door seal, it would be a waste of energy to deny just how important this threshold gasketing really is within the operating hierarchy of this wattage-hungry cooling system. It must be installed properly, perhaps even heated, and most definitely considered an important operational part of the freezing equipment’s pecking order.

A professionally conducted energy audit determines whether your commercial freezer really is as indestructible as it looks. Tasked with analyzing the energy envelope inside these insulated enclosures, the tests track waste energy, monitor losses over time, and even identify the reasons for the thermal shortfall. Furthermore, a properly identified energy consumption profile helps govern certain system management factors. For example, harmful organisms can’t exist when freezer and coolroom audits rule supreme.

Reviewing Coolroom Energy Audits 

If it helps, picture a traditionally maintained walk-in unit as a two-dimensional auditing system. A couple of thermometers take care of this job. The appliance caretaker places one temperature measuring device in a suspected warm spot, then he places the next one at a known chill zone, perhaps right below the refrigeration unit. Measured via a differential calculation, the energy losses are found. But this is something of an approximation, not a scientifically conducted procedure. True energy audits use time-based temperature monitors, devices that compile a three-dimensional model so that a fully illustrated energy profile is produced. That energy envelope accounts for foot traffic, refrigeration output energy, and wall insulation issues, among many other factors.

Controlling Harmful Organisms 

If that audit is conducted diligently, then every conceivable operational factor becomes part of the energy profile. Is the food being handled properly? That factor is established and recorded in the report. That compiled assessment also notes any cross-contamination problems, marks insulation seal damage, and clearly shows the spots where the chamber is experiencing major structural issues. Furthermore, unsanitary pools of water and questionable growths are labelled as actionable trouble sites, places where mildew or mold are beginning their spread. That audit, as it figuratively scours its way through your freezer and coolroom, is sure to uncover hidden growths. As for the immediately obvious patches, the sites where harmful organisms are taking hold, these are quickly recognized when a comprehensively run audit is executed correctly.

Think of freezer and coolroom audits as a weapon in a two-pronged attack. The second part of this food safety program is a maintenance plan. The audit swings into action when system energy ratings incur hefty energy losses. Meanwhile, the maintenance program prevents problems before they occur. Working together, the two techniques stop bacterial growths. As for the audit, this tool looks deeper than a standard maintenance strategy, so deep that it sees exactly where the cross-contamination problems and foot traffic puddles are occurring. Identified in no time at all, the assessment report will also suggest a sanitary solution, one that does away with the harmful organisms before they can impact the stored food.

The briny air pinches the nostrils of the seafood processing personnel as they shuffle in for their next shift. Nearby, the hum of the coolrooms and freezers are maintaining a strictly mandated chill. Happily, safe seafood storage guidelines are properly cooling the large warehouse. All while those frigid temperatures are maintained, the marine product rolls through the seafood processing plant. Down there, among the machinery, are those fish being filleted at a table?

What’s Being Prepared Down There? 

That’s a ten out of ten for visual acuity, for those are filleted fish. In point of fact, a seafood processing factory covers more than fish preparation, although this is the predominant ‘catch of the day,’ as it were. Elsewhere in the warehouse, there are crustaceans, so expect the crack of lobster shells, plus the rending of crab soft tissue. The food of the sea also includes all kinds of shrimp and even more types of mollusks. Every single organism on the steel-belted conveyor belt is obviously perishable, which is a trait the food shares with animal meat. Furthermore, seafood tissue is loaded with water, so the refrigeration program has to account for the added moisture. Likewise, shucked and un-shucked shellfish organisms are bound to affect the applied refrigeration temperatures. Basically, the processing temperatures inside a seafood processing factory require special consideration, not the generic chilling program that worked well inside a meat storage facility.

Coping with Contrary Environments 

Seafood preparation is a tricky business, so the refrigerated coolrooms and freezers are generally manufactured to quickly facilitate the processing operation. Fish or crustacean, shrimp or mollusc, the temperature matches the marine product. Curiously, as delicate as this work is, the plant layout requires a far more rugged design maxim. The food is sensitive to temperature shock, and it will lose flavour if that chill isn’t maintained. However, this is also a corrosive setting, a place where saltwater coats every exposed surface. Specially treated metal panels, each equipped with an effective insulating barrier, must be installed. Finally, water treatment and salt packing procedures supplement the cooling equipment. They preserve the seafood and filter wastewater from the metal-laced conveyor strips.

This isn’t yet another meat packing or processing factory, it’s a seafood processing plant, a site that maintains water level while also combatting the brine in that fluid. Cross-contamination issues are eliminated in here by carefully segregating the fish from the harvested shellfish. Temperatures are set in each zone to account for the shucked marine products, the filleted fish strips, and a dozen other marine-oriented parameters, all so that the seafood arrives fresh and safe inside a local supermarket cooler.

A work-frazzled kitchen chef works his magic. The ingredients of his creation centre on a juicy cut of prime rib roast. Surely the meal is destined to satisfy a hungry customer before he happily orders dessert, right? There’s a factor we’re forgetting, a point in the cooking process that comes between meat delivery day and the frying pan. Coolroom performance, a quality freezer arrangement, directly influences frozen meat freshness.

Coolroom Storage Conditions: The Freshness Question 

Everyone knows that meat is preserved when it’s properly stored at a low temperature. The chilly environment stops cellular degradation, forces microbial organisms into a state of dormancy, and freezes the water in the meat’s soft tissues. Safely sustained at 0°C or below, the frozen meat defrosts as a tasty cut because freshness has been locked into this perishable commodity. That’s the ideal objective here, but the freshness factor is a fussy creature. For example, should the temperature drop too low, certain enzymes can be stripped from the meaty tissue. The food is still safe to consume, but now the meat has changed to the point that the intended flavour is lost.

Shutting Down Textural Alterations 

The clue here is the watery liquid that freezes on top of the meat. That icy lining isn’t limited to the surface of the beef or lamb cut. It’s permeating every cell of the animal tissue and forcing those cells outwards. If those cell walls rupture, the food is going to arrive at the table as a mushy mess, a meal even the most creative cook won’t be able to save. If that unfortunate scenario is to be avoided, ceratin freezer variables require attention. The quantity of water in the freezer and the time taken to chill the meat are both manageable variables here, so use a top-notch walk-in appliance, not some generic model that lacks a quick-freeze feature. Incidentally, should this problem persist, an energy audit is recommended. Damaged door seals, poorly trained staff members, and ageing insulation panels all impact the cooling envelope, which is when superior appliances turn bad.

Even if the branded coolroom unit is working at peak efficiency, operator errors and poor management techniques compromise this freshness middleman every day. Open doors and those selfsame damaged components allow oxygen into what should be a fully sealed room or enclosure. Freezer burn sets in, coolroom performance goes out the window, and the meat is ruined. Counterintuitively, ice-damaged meats can even end up dried out, probably because the ruptured cells can no longer store fluids. Loss of enzymes, flavour and texture, quality frozen meats are unlikely if a freezer is underperforming.

Industrial plastic curtains have received their fair share of coverage in past articles. They reduce energy losses, prevent insects from entering food-safe areas, and generally act as a conventional room threshold, albeit one that’s made out of PVC strips. General benefits aside, though, just why are plastic strip doors ideal for commercial coolrooms? Could it be the fundamentally connected but necessarily segregated nature of this work environment?

A Workflow Facilitation Mechanism 

All right, commercial coolrooms are every bit as enclosed as any other refrigerated zone, but a commerce-oriented operation requires a chain, a movement of merchandise. This is a bit of a dilemma, right? The cold air has to stay right where it is, but traffic must flow. By advocating a PVC strip curtain solution, one that installs across the access threshold, we reach a suitable compromise. Commerce flows, the cold environment is maintained, and business prospers. As we’ve said in past articles, there are many practical reasons for adopting this pliable barrier, including the preservation of a chilled food-safe zone, but this product transaction issue pairs practical concerns with an important logistics-based component.

Addressing Utilitarian Considerations 

Speaking of ideals, the perfect commercial setting is clean and productive. Everything works flawlessly, and the kitchen personnel are all meticulous workers. In reality, this ideal is hard to sustain. Dirty shoes track dirt. Bacteria grows in standing water, then flies circle those damp patches. Industrial plastic curtains overlap their strip sections so that these flying pests can’t penetrate the coolroom threshold. Sure, a weekly delivery of meat or fish is taking place. Traffic is looping back and forth, the merchandise is creating a supply chain between the delivery quay and the refrigerated cooler, but only the brawny delivery employee and the temperature-sensitive products are pushing through those overlapping PVC strips.

Leveraging the Scalability Factor 

Commercial operations vary dramatically, both in size and the length of that supply chain. Essentially, large business enterprises create a regulated processing tunnel. The industrial plastic strips act as a prominent threshold expeditor in that virtually sealed supply chain. Movements between narrow walk-in freezer doors and catering establishments rely on that plastic-sealed portal. On scaling pliable doorways upwards, their transparent strips also create a barrier between the outside world and frosty warehouses so that numerous product-loaded forklifts can safely zip through their high-visibility, abrasion-resistant panels with minimal effort.

It’s the supply and conveyance chain that acts as the lifeblood of the commercial cooling industry. The refrigerated commodities are properly stocked, but they’re also always on the move, carried by man, pallet jack, or forklift truck. Stopping tiny pests and energy losses, the flexible barriers keep the thread of productivity firmly intact.

A repair technician’s best friend, a systematic approach to troubleshooting, opts for an all-inclusive condenser coil check when coolroom conditions are less than ideal. What if there’s a build-up of dirt in the freezer area? Besides being an unhygienic way to run what’s lawfully defined as a food-safe enclosure, that messy accumulation is hindering the refrigeration unit. Intent on his exhaustive maintenance check, the tech checks the condenser section.

Condenser Coil Checks: Troubleshooting Environmental Issues 

As any hygiene expert will tell us, clean coolrooms and freezers aren’t just recommended, they’re a necessity, as outlined by any government regulated food safety authority ( If that assiduously sanitized room isn’t kept free of dirt, then the food is at risk of contamination. Furthermore, the condenser coil will become less effective because the collecting dust and dirt are acting as an insulating layer. As a knock-on effect, the compressor mechanism works harder to offset the effects of this dirt jacket and maintain the required low temperature. In the end, however, the compressor is fighting a losing battle, one that results in system failure, for that layer of dust and dirt isn’t going anywhere, not unless a compressor coil check rectifies the issue.

Discussing Performance Hampering Factors 

A walk-in freezer can limp along for years if the condenser section is dirty. Sure, the heat exchanging mechanism is attenuated, the compressor is working harder, and an overall efficiency drop is unavoidable. Still, the appliance will limp along, at least until the strain breaks the back of that mechanically exhausted compressor. What should be happening is a maintenance check, a program that adds a full page of inspections that highlight condenser coil operability. Is there unhampered airflow in and around this heat exchanger? Is the coil clean and undamaged? Finally, large capacity units rely on more than open space and ventilation. They use powerful fans to push excess heat through a vented duct. The inspection not only troubleshoots the condenser coil in this high-capacity system, it also ensures those fans are clean and operating at their best.

If coolrooms and freezers depend on a refrigeration unit, shouldn’t we properly identify that cooling system? After all, that cold airflow is produced by heat exchange science, not magic. The condenser coils receive the vapourised refrigerant. That gas then cools until it’s a liquid. On the coil surfaces, the heat exchange mechanism produces thermal energy, which is blown away by a fan or simply vented. The duty of the tech here is clear, with his troubleshooting skills focusing on maintaining coil conductance. Consequently, these coiled surfaces must be kept clean, and the airflow around the surfaces must flow freely.

Expert walk-in contractors plan out their services. Rest assured, the practice is done professionally on paper or in computer space. Furthermore, the chosen installation site is gauged according to a suitability threshold. It’s hard not to wonder about the factors that influence this location-based study. Is this check used because the installation site is too small? Perhaps, or maybe there’s another factor in play.

Explaining Suitability Checks 

Contemporary coolrooms and freezers are factory manufactured and injected with composite insulation panels. It’s because of this pre-designed approach that the prospective site requires an initial suitability check. Will those wall panels assemble cleanly inside the desired room space? Perhaps an outdoor cooling enclosure is the only workable solution if the inspection falls short of a viable installation method. Even if those dimensional constraints are satisfied, there are other problems to consider.

Construction-Oriented Site Surveys 

As we all know, there’s a power hungry monster locked inside refrigeration equipment. The suitability check accounts for this energy exorbitant design by sourcing low-power parts, but the gear is still likely to draw more power than the average commercial appliance. With that fact in mind, the check turns its attention to the power distribution system, to cable capacity and line circuit breakers. High capacity circuitry may be recommended after the inspection so that the coolroom doesn’t create a system overload, one that would black out the entire kitchen. Similarly, the plumbing pipes, especially the drainage system, may need to be upgraded to handle a sudden defrost cycle.

Working with Ducting 

An unobstructed channel is essential here, with the airflow passing unhindered from some predetermined outside wall. If that outside area is blocked by debris, it must be cleared. Incidentally, if the muck and mess are airborne, then system filters are a must-have feature, for that particulate matter cannot be allowed to enter a sanitary area where edible foodstuff is stored. In order to underscore this provision, a maintenance program should be recommended by the suitability check. Depending on the results of the inspection, the program could initiate a daily or weekly filter check so that a satisfactory hygiene threshold is established in the coolroom.

On a deeper level, the professionally conducted inspection comprehensively assesses factors that are invisible to others. The floor, for instance, could be energy leaky, so floor insulation would be required. Beyond the floors and walls, their dimensional outlines and insulating properties, there’s the site construction to assess. These checks ensure the existing ducting and plumbing and electrical fittings are up to the job of working with a powerful coolroom.

Pressure relief vents in cool rooms are designed to create a work-amicable relationship between tired employees and stubborn, large-scale coolrooms. If that explanation stops just short of clarifying the mechanical component, picture it as a coolroom access assistant, a device that overcomes pressure differentials. Here’s a deeper look into the functions that define this atmospheric equalizer.

Low-Pressure Walk-in Conditions 

When the locking clasp of a coolroom door is disengaged, instinct says we should pull. Curiously, there’s a suction effect that needs to be overcome before the door moves outwards. The larger the door, the stronger this effect becomes. So what do the walk-in cool room designers have to say about this phenomenon? They talk about air seals and fans, suction side pressures and the cooling air that makes airborne molecules condense. In short, the sealed enclosure maintains a lower pressure environment because of that seal and the refrigeration unit chugging away inside the closed chamber.

Pressure Relief Vents: What are they? 

If that pressure differential is to be mechanically equalized, a feature-rich walk-in freezer or equally well-equipped walk-in cooling unit will come preinstalled with an atmosphere-balancing pressure relief vent. Assembled from springs and metal sleeves, plus an electric element to stop the mechanism from freezing, the venting device relieves pressure differentials. As the atmospheric variance is negated, the enclosure door then opens effortlessly. Therefore, primarily, this is an access assisting vent, a low-pressure valve that equalizes inside and outside pressure discrepancies. However, that primary feature is accompanied by another important function, one that will be explained in the next paragraph.

Additional Functions for Pressure Relief Vents 

If this spring-loaded device helps to address low-pressure coolroom conditions, what other functions could it be squeezing into its feature list? Well, pressure relief vents also reduce walk-in enclosure stress. Think of it, the pressure offset caused by the cooling mechanism places a strain on the seams and joints of the cooling chamber. The parts expand a little, then they contract. Over time, those seams will split. Energy leakage is next, plus a corresponding breakdown of panel insulation as the moist air escapes into those seams. The pressure relief vent earns its middle descriptor here, for it really does “relieve” pressure-induced stress.

Described as self-regulating environment equalizers, these vents serve as door balancing aids. They assist tired operators by reducing the force required to open and then close the seal. Next on the function sheet, pressure relieving vents minimize seam and joint stress, which means the walk-in unit will work at its operational best for years to come.

Just for the last few minutes, you’ve watched water dripping. It’s inside your biggest freezer, this wet drizzle, inside a space you diligently clean all the time. What’s in that dripping water? Is it clean? It can’t be left to pool and become a bacteria-populated wet spot, a puddle that darkens with dirt as foot traffic ploughs through it, so how do you stop that steady drip?

Condensation Causes 

A mess of towels and rags on a cool room floor isn’t something anyone wants to see. This is a wet patch, an area that’s an ideal breeding ground for mould. If the water is beading and gathering itself into rivulets, condensation is a likely culprit. First of all, such problems are usually traced back to obvious explanations. Don’t keep the freezer door open for an extended period of time. If the staff has learned this little nugget of information, then there may be a problem with the door seal. Have that seal inspected by an expert technician. Another moisture culprit in your freezer, the evaporator coil, causes excess moisture when there’s an icy build-up. Maintenance is the likely remedy this time. Clear the coil drainage channel of dirt and ice, then test the cooling unit to see if it’s still producing excess water.

Freezer Drip Cure-Alls 

The diagnosis of an unbalanced refrigeration unit or a faulty door gasket takes us halfway through the battle. The water drip is definitely on its last legs, so where do we go from here? Before you wipe up the puddle with soapy detergent, check the chamber defrost gutters and the drainage pans in and around the refrigeration appliance. Due to the nature of that latter clean-up task, this job is best left to a qualified refrigeration engineer, someone who can safely remove a housing cover and wipe away the moisture, plus the dirt that’s accumulated in that pool. Next, water is attracted to easy-access pathways, so they’ll use the seams of your freezer instead of the built-in drainage channels when they’re overly exposed. Older models suffer from this flaw when the caulking in the enclosure seams break down. Consider a recaulking job if those seams continue to funnel condensates.

A mucky puddle, produced by some unknown dripping water source, draws dirt and mould like some frosty magnet. Trace the cause of this liquid rivulet, if possible. Keep the freezer door closed, replace the gasket, and generally have the compartment inspected for energy leakage. Then, if the problem repeats, incorporate a predictive planned maintenance program into your freezers’ operational schedule, one that’ll keep the refrigeration unit’s inner workings balanced and moisture-free.

Traffic door systems are installed in coolrooms when access problems become unavoidable. We’re talking about the passage bottlenecks that exist between the threshold of a large-scale freezer and the narrow aisles that contain spoilable commodities. Pallet jacks and wheeled trolleys zip between the evenly spaced bollards guarding those thresholds, but larger vehicles are obstructed. Designed to segregate pedestrians and lifting vehicles, the system exists as a best practice security solution.

Best Practice Entryway Screening 

Commercially viable coolrooms and freezers use heavier equipment profiles. Even up on the refrigeration unit, there’s a two or three fan housing with wider bore cooling pipes working to chill the large area. Split into numerous work zones, the squared portals are equipped with transparent PVC curtains and a traffic door system. That latter fixture is installed as a series of aligned bollards. Spaced just-so, the security posts allow pedestrians and vehicles of a predetermined width to pass freely, but larger vehicles are stopped in their rubber tracks.

Perimeter Defense Guards 

Once the door bollards have been installed, their measured presence screens the different work areas. Meanwhile, around the wide floor space of the coolroom, there’s a legion of additional bollards. Every security post is situated at a strategic turning place or sensitive load bearing wall. They’re possibly padded and definitely reinforced. Installed in front of narrow wall pillars and blind access doorways, the waist-high stanchions stop unwary workers, and the building’s structure, from a nasty encounter with a forklift truck.

Cold Storage Protection Systems 

At this point, we’re talking about pedestrian traffic, which is as it should be because these stout posts are designed to preserve human life. However, there’s more to a bollard traffic door system than its screening credentials. The posts also act as the leading edge of a mechanical cage, a frame that prevents cold storage room bay doors from physical damage. Fastened around the larger entryway, the security posts act as a distancing tool, a barrier that stops door damage when heavy vehicles aren’t fully under the control of their operator.

Importantly, security problems are created by a large door rip. The weather penetrates a regular storage area, and the contained products are put at risk. In freezers and coolrooms, however, that rip or broken door seal equals an energy imbalance. The self-contained arctic environment is no longer maintainable, or, if it is, then huge amounts of energy are wasted to keep the large space cool. Bollard-lined traffic door systems eliminate that disastrous possibility. Furthermore, perhaps with the aid of a reflective strip, the bollards guide traffic while they screen the work areas from heavy vehicle penetration.


If a walk-in coolroom is an essential modular construct, then the installed panel system is the armoured envelope that defines the thermal characteristics of this insulated cooling space. The installation panel system in question is designed to assemble readily, seal reliably, and present a unified thermal barrier. Built from advanced materials, the panels employ smart coupling technology, such as the renowned cam-lock coupling system.

Installation Panel Systems: Locking Mechanisms 

Before advancing any further, just how do the modular panels create that steadfast seal? Basically, there are special locking systems that are built specifically for the job. They’re typically attached to the panels as toughened plastic blocks, with heavy gauge hooks and reinforced pins taking on the role of the dependable fasteners. They come together when the panels are aligned, lock in place, and use their heavy gauge stainless steel outlines to secure the assembling chambers’ many wall panels. Used in concert with a special angled key, the tool and wall locking mechanisms guarantee fast and secure modular assembly.

Cool and Professional Assembly Skills 

Whether the locking system requires a cam-wrench or a traditional screwdriver, the work still requires an expert construction service, an engineer and technical group who can build this framework with confidence. Perhaps we should be talking about competence as well as confidence, for the structurally stable module is hardly finished. Next, there are commodities fittings and plumbed pipes, plus their drainage channels to install. There’s a ceiling coupled to the walls now, and there’s an insulated floor. Next, the composite wall panels are installed. These panels are laminated with an extruded polymer, then they’re glued to durable metal skins. The installation panel system has taken on a layered architecture, with the modular panel system on the outside, the composite, metal-skinned insulation panels on the inside, and the open area chamber right in the centre. Inside that core, a few light fixtures, wire-mesh shelves, and an energy-efficient refrigeration unit complete the structure.

Tongue-in-groove panels, cam locking mechanisms, and gaskets form the structural backbone of a modular coolroom. Next, a layer of temperature resistant caulking increases the unit’s R-factor and produces an optimally sealed cooling space. When this sealed space is standing tall, composite insulation panels are fixed inside the enclosure while the door seal and electronic control system receive attention. Finally, the refrigeration housing and all of its fitting are installed, tested, and placed in an inactive but ready stage until the furnishings are carried inside. Properly inspected, the coolroom is ready to produce its frosty atmosphere.
