Functions of Pressure Relief Vents in Walk-In Freezers
07 October 2019
To an engineer, there’s nothing mysterious about a PRV (Pressure Release Valve) device. It functions as a system safety feature when potentially dangerous fluid pressures are present. If some overly compressed liquid or gas medium stresses an equipment fitting, then the valve quickly dumps the fluid. That’s all very interesting, but what do these safety devices have to do with walk-in freezers? Are there pressure build-ups happening inside a freezer? Strangely enough, just the opposite is true. Pressure Release Vents Regulate Airborne Forces A PRV does have a role to play as a disaster compensatory mechanism. The valves are often […]

Condensation Issues in Cool Rooms: What are the Possible Causes and Solutions?
18 September 2019
Most cool room managers are familiar with several condensation triggers. A troublesome door or door seal allows air to seep into the chilled enclosure, or maybe a new staff member has been propping a hinged panel open for several long minutes at a time. Be that as it may, there could be several unknown causative factors for every easily explained condensation instigator, so we need to work smart here. The Science Behind Condensation Challenges Warm air stores heat, which is probably why wet and warm countries get so humid. The air literally becomes heavy with tiny beads of water. Now, […]

Reasons Why Bacteria and Mould Can Grow in a Cool Room
03 September 2019
Although restaurateurs would wish otherwise, mould can survive inside a chilly cool room. That’s clearly an unacceptable situation. If a hardy mould strain somehow finds its way towards a rack of cold-stored food, the opportunistic growth could very well cause inventory spoilage. And that’s the least of a walk-in unit’s worries, for contaminated foodstuff constitute a significant health risk. Using a know-thy-enemy mindset, though, we can subdue this pernicious threat. Know About Mould-Friendly Conditions If a cool room engineer were to sit down with an HVAC worker, they’d probably share tales about their worst jobs. Right away, they’d discover they […]

Purposes of Aluminium Checker Plates in Coolrooms
20 August 2019
What exactly is an aluminium checker plate? It’s a strange term, but it translates readily enough. These panels of lightweight metal are installed in work areas as high-traction floor plates. Laid in a grid pattern, they’re adorned with raised edges, which serve as tiny groups of anti-slip outcroppings. Just to emphasise that point, the treads serve a purpose; they’re not there to provide an ornamental overlay for the floor. Coolrooms at Ground Zero Ideally, their metal floors are dry and clean. More likely, there’s a very fine film of water on the ground. That liquid is going to be slippery. […]

Cool Room Installation for Your Business: Factors that Determine the Size You Need
07 August 2019
In order to estimate the dimensions of a business-ready cool room, begin with a sheet of paper and an open mind. Find a quiet space to think and begin by writing down all of the items that’ll be stored inside the refrigerated room. Impacted by the size of the installation site, let’s make sure this initial design factor doesn’t influence the size of the cooling envelope too much. Splitting the Cool Room One single space maximizes the available installation area. The modular walls and insulated fittings drop into place around the room’s own walls, so there are no extraneous fixtures […]

Damaged Cool Room Doors and Panels: Why Do They Need Immediate Replacement?
19 July 2019
It’s not enough to tag a defect on a cool room door. On a similar note, panel damage can’t simply be noted in a maintenance log book. A failure to act on such seemingly trivial staff feedback really could have dire consequences, all of which will negatively impact a cool room’s established functions. For one thing, damaged doors and panels leak energy. Then there’s food freshness problem, too. Chamber Breaches Destabilize Cooling Envelopes From a practical standpoint, a damaged door won’t open. If it does swing open, perhaps after applying substantial shoulder muscle, it jams open. Clearly, a stuck cool […]

Cool Rooms Play an Important Role in the Success of Flower Shops
17 June 2019
Let’s cut straight to the chase. Cool rooms don’t just keep flowers fresh, they stop them from blossoming. In effect, the cold acts like a pause button. That means, should a large delivery of floral merchandise arrive at a shop, the staff can create a biological buffer for themselves. Instead of the merchandise opening, according to some biological imperative, a temporary halt is placed on its growth cycle. Cool Rooms Are Floral Time Machines Or maybe they should be described as stasis chambers, like the suspended animation devices found in science-fiction movies? Whatever the label, their purpose is clear. By […]

Ways to Avoid Hazards in Dismantling and Relocating Coolrooms
07 June 2019
Starting with an obvious observation, the team members who are responsible for taking apart a coolroom need to protect themselves. Granted, if this is a newer construct, it’s likely been designed to come apart easily. In other words, it’s modular. That being said, sharp edges will become exposed as the chamber breaks apart. Wear protective gloves and observe the following guidelines. Electrically Isolate the Equipment There are live electrical circuits humming quietly inside operational coolrooms. Even when the refrigeration equipment isn’t powered, perhaps because the thermostat isn’t active, there could be a dangerously high electrical charge nearby. Remember, this equipment […]

How Coil Performance Restoration Can Contribute to Coolroom Efficiency
15 May 2019
If a coolroom’s layout is optimized, yet the equipment’s still drawing way too much electrical energy, something’s still not right. Odds are the refrigeration unit has some kind of a performance frustrating issue. Even more frustrating, this issue is ongoing. It’s not getting any better, and it won’t until someone tracks down the energy siphoning cause. Calling in an expert service engineer, that pro-worker should head straight to the equipment coils. Obstructed Refrigerator Coils Cause Energy Losses Indirectly speaking, the icy build-up hampers coil efficiency. Perhaps there’s excess moisture coming off of a row of frozen meat, or maybe the […]

Coolroom Heating Cable Replacement Services: Hire C & M Coolrooms
06 May 2019
Contrary to popular opinion, refrigeration services don’t always place a heavy focus on cooling equipment. Admittedly, that’s their raison d’ê·tre, their main role in life, but this is a profession that covers many different engineering disciplines. Why, there are even times when C & M Coolrooms technicians find themselves repairing or replacing heating cables. Where Are The Heating Cables? Warming wires of this type can be found in several locations. Before going any further, however, these aren’t true heating elements, they are radiant fractional amounts of thermal energy. For example, a cold concrete floor could crack because of the minus […]

Installation of Customised Coolroom Shelves and Racks: Hire C&M Coolroom Services
17 April 2019
When you are building your business, you know that you want to incorporate the best materials and equipment possible. Whether you are filling out a pharmaceutical building or you are preparing a commercial kitchen, you’ll likely need to lean on the services of a coolroom. Coolrooms are an integral addition to any facility where temperature control is of the utmost importance. Coolrooms aren’t just big, cold rooms, however. Instead, coolrooms can be a vital part of the work that you are doing. Today, we are going to go over the benefits of installing customised shelves and racks to your coolroom. […]

Basic Factors to Consider in a Custom-designed Coolroom
02 April 2019
Somewhere out there, a custom-built walk-in freezer has rejected its cookie-cutter layout. Elsewhere, perhaps in a remodelled supermarket, a designer has used out-of-the-box design practices to construct a glass-doored coolroom that looks appealing. Behind the steel and glass framing, beverage stockers are working unobserved. Clearly, singular designs, custom-designed coolrooms satisfy every conceivable client stipulation. However, for every unique system layout, an equally unique problem can develop. Avoid A Super Streamlined Layout Perhaps the cold room is going up in a smaller than average piece of floor space, or some interior designer believes the time has come to develop a super-skinny […]
