Benefits of Energy Saving Devices in Coolrooms and Freezers
07 December 2016
Energy audits on walk-in coolrooms and freezers tell us that twenty-percent of all consumed energy goes straight to these large refrigerated rooms. That’s a bit of a problem, considering the premium put on energy savings today. But there is a unique set of tools, energy saving devices that are turning the tide. Let’s see these tools in action and find out all about the benefits of energy saving devices in coolrooms and freezers. Programmable Thermostats A set-it-and-forget-it mentality doesn’t yield big savings when the controlled appliance uses four large walls and an industrial-grade refrigeration unit. A far more potent controller […]

What is Refrigeration Operating Efficiency for Coolrooms and Freezers?
01 December 2016
Coolrooms and freezers are high-end engineering constructs, but they’re also influenced by intangible forces. There’s the mathematics of thermal envelopes to consider, plus the laws of thermal dynamics, rules that conserve energy within the refrigeration unit. Refrigeration operating efficiency is an important parameter here, one that determines how well the cooling space runs, but what factors subscribe to this calculable rating? Refrigeration Operating Efficiency Performance coefficients are important in the walk-in coolroom and freezer sector because these oversized refrigerators consume more energy than any other appliance. Keep that fact in mind next time a coolroom door is left open for […]

Coolroom Accessories and Parts
16 November 2016
Coolrooms lack basic features when they’re initially constructed. Certainly, the modular panels interlock superbly and the powered refrigeration unit works efficiently, but everything else feels, well, unfinished. Coolroom accessories and parts (spares) address this concern. Better yet, they transform the empty space, give it purpose as a high-functioning storage area that can handle any temperature-sensitive commodity. It all begins with energy conservation. Sealing Accessories Tough polymers produce airtight seals that stop energy leakage. The existing rubber seals are probably up to the job, but they will wear as time has its way. Additionally, icy buildups have a habit of forming […]

Why Freezer and Coolroom Door Latches Should Be Maintained and Checked Regularly
02 November 2016
Sound maintenance methodologies keep freezers and coolrooms in perfect working order, but there’s a hierarchy to the housekeeping work that takes care of this special enclosure. Primarily, a reliable containment area is required, so the chilled space requires insulation and a seal. Door latches enforce this environment, but they rely on mechanical principles, on a mechanism that could fail. Not to worry, maintenance engineers check doors for fastener issues. Assessing Causes A well-maintained latching mechanism exhibits a mechanically-assured reliability factor. It snaps home and locks the door against a pliable seal that lines the door frame. A properly operated door […]

Purposes of Pressure Relief Vents in Walk-in Freezers
24 October 2016
An industrious examination is the only methodology worth adopting when the mechanisms running walk-in freezers need clarification. There are the obvious components, the composite insulating panels and cooling units, parts that require little explanation, but the purposes of pressure relief valves don’t subscribe to easily relatable guides. Instead, this essential component needs its own detailed set of instructions, so let’s begin our engineering-oriented tale by taking a look at pressure equalization needs. Walk-In Freezers and Pressure Equalization Fatigue runs up the arms of hard-working employees when they tug the door handle on a walk-in freezer. A pressure differential has built […]

Physical Properties and Uses of Polystyrene in Freezers and Coolrooms
10 October 2016
Some dynamic duos fight the elements, not costumed villains. In freezers and coolrooms, for instance, two forms of Polystyrene battle energy losses. Expanded Polystyrene (EPS) receives a mention first due to its immensely popular application base. The second member of this heroic pairing ranks almost as highly, although this latter energy champion is extruded, not formed from a closed-cell expansion process. Let’s take a look at both of these variations on a theme to see where they fit within freezer and coolroom designs. Foam Insulating Panels The general uses of this ubiquitous foam vary dramatically. Fragile items are packed in […]

Applications and Purposes of PIR Fire Resistant Panels
21 September 2016
Polyisocyanurate (PIR) is a dense thermosetting plastic that exhibits highly desirable thermal properties. Primarily, the rigid material is designed to insulate temperature-sensitive environments, but this feat is accomplished in two very different ways. Let’s look at the applications and purposes of PIR, its uses as a capable heat isolator and an even more capable thermal barrier. Tough Composite Wall Panels Use Soft-Centred PIR Cores Insulating wall panels are constructed from several layers of advanced material. The inner and outer layers are mechanically strong and aesthetically attractive, but it’s the core of these composite panels that interests us, for PIR exists […]

Uses of Clear Plastic Swing Doors and Plastic Strip Curtains for Coolrooms
07 September 2016
Plain binary access systems efficiently protect static storage environments. Unfortunately, doors that are forever opening and closing won’t work in a high-traffic coolroom. The door, beautifully sealed as it may be, becomes a workflow bottleneck. Clear plastic swing doors and plastic strip curtains offer a third option, one that happily removes that productivity-crippling bottleneck. The Third State of Coolroom Entrance The middle ground we seek uses plastic swing doors and plastic strip curtains. These insulated dividers keep the temperature cool on one side, but the workflow bottlenecks evaporate. The kitchen employee simply swats the door, pushes through the plastic envelope, […]

Coolroom and Freezer Door Functions
22 August 2016
Considerable focus is placed on the design of a coolroom, and much of that attention ends up on the interior, for this is where stored commodities receive their temperature controlled airflow. In maintaining the chill within the insulated alcove, the thermal isolating properties of the walls, ceiling, and floors are duly assessed, but what of the primary access point? Coolroom and freezer door functions could certainly be perceived as a chink in the insulating armour here, so those functions need to be evaluated if we’re to guarantee the integrity of this entryway. Multifunctional Configurations Strong rubberized seals and spring-loaded mechanical […]

Functions of Coolroom Panels
09 August 2016
If we were to classify coolroom panels as little more than a series of insulated wall segments, we’d be doing these state-of-the-art composite units a disservice. Yes, each rectilinear component is designed as part of a jigsaw-like build, one that precisely maintains the chilly environment within the coolroom, but it’s also imbued with other talents. We’ll begin with durability. Layered with Structurally Adept Innards Multiple layers define coolroom panels. Fused together to create an engineered whole, the sandwiched filling uses a multipurpose recipe, with the steel front face serving as a mechanical barrier. The impact of a metal catering trolley […]

What’s In A Freezer? A Discussion on the Parts That Make It Work
25 July 2016
Find a large room with plenty of open floor space because we’re going operate on a restaurant-grade walk-in freezer. Dismantled and laid out in a sprawling range of disparate components, all of the freezer parts will fill a substantial chunk of factory floor real estate, so let’s watch our step. The Structural Anatomy of Freezers The modular configuration separates as a series of floor-to-ceiling panels. Additional ceiling and floor panels incorporate apertures for refrigeration units and drainage ports. The floor in this design is typically equipped with a slip-resistant lining, perhaps patterned metal extrusions or a mineral-coated resin. Inside the […]

Why is it Ideal for Businesses to Have Customised Freezers and Coolrooms?
18 July 2016
A hotel owner builds with a passion that ensures every room is fit for a king. It’s the same with the restauranteur, the host who serves fine foods and edible delicacies, except this owner lavishes attention on the dining area. Kitchens are treated with equal care, but their form is dictated by other factors. Additionally, the layouts of food preparation and storage areas are monopolised by function, the location of pipes and other utility zones. Preparation spaces must scale to suit this carefully managed commercial environment, so customised freezers and coolrooms defer to these work-specific layouts. Of course, there’s more […]
