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.
Strong rubberized seals and spring-loaded mechanical levers guard the access route when catering personnel hustle into the chilly alcove to pick up foodstuff and prepare a meal, but this contemporary storage outlay is only one of many possible coolroom designs. Modern beverage cabinets represent an example of expanded utilization. In here, the front-facing wall is replaced by numerous glass-paneled doors. A concealed doorway is in the rear of the coolroom, so the attending stockroom worker is always on hand to replenish an empty beverage shelf.
Expanding on Coolroom and Freezer Functions
Compressible rubber seals use wear-resistant polymers to cancel out the abrasive influence of a metal door on a track. Similarly, those larger units are designed from durable alloys, metals that won’t wear or deform when a meat trolley slips down a padded ramp. The build is obviously toughened to avoid contraction events, the curve and deformation effects caused by subzero temperatures, but they’re also imbued with other essential properties, including a low-profile design that bolsters a hygiene-oriented work environment. Fasteners and door controls, seals and sliding tracks, all of these parts are constructed in such a way as to emphasize a sanitary design ethic.
Adopting Electrically-Enhanced Builds
Manually operated door controls are hard to access when a staff member is balancing multiple items of food, wine, or chemicals, so an electrically-actuated mechanism works in tandem with spring-loaded door controls to power admission into the frosty alcove. That same methodology is typically applied to large-scale doors, with electrical heating elements representing the front line of this approach. The heater stops the seal from freezing and cracking. Of course, this self-regulating wire only provides enough energy for these tasks and no more.
In properly establishing coolroom and freezer functions, we’re working within a mechanical framework, an area that must eliminate air infiltration while providing a consistently accessible route to the stockpiled materials stored within the cold alcove.
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 or a slaughterhouse hook is ably stopped by this facing surface. Additionally, this external layer is sometimes further strengthened by bonding a polymer-reinforced finish to the metal, a coating that absorbs shock and abrasive impact.
Enhanced R-Factor Protection
As tough as the prefabricated panels undoubtedly are, durability is not their primary function. Under the shell-like outer surface is where that main function sits, for it’s down here at the core of each panel that we find specially formulated polymers. Fabricated as flattened plastics that have been chemically bonded to the metal framework, expanded polystyrene (EPS) foam inserts thermally insulate each composite segment. The result is full heat isolation and a preservation of the cool inner environment. Thermal resistance (R-factor) is the bailiwick of such engineering plastics, with EPS topping the insulation list, but other core insulants are available, including polyurethane.
Multipurpose Modular Wall Assets
If the last two paragraphs have proven anything, it’s that these prefabricated components are built to excel across multiple usage areas. They cool the sealed chamber while ensuring it’s protected from bumps and thumps. Endowed with composite aptitude, the coolroom panels also strengthen the overall structural form of the storage space, thus gifting the room with construction-grade stability. Interestingly, there are several installation methods that subsidize this strengthened build. Mechanical fasteners accelerate assembly routines, but there are also tongue-and-groove paneling formats that reduce this installation stage to a series of snap-on maneuvers.
In rewinding to primary features, the prefab panels are mainly thermal barriers. It’s from this cooling backbone that multifunctional aptitude extends, with mechanical strength topping the supplementary feature list. Steel and aluminium imbue the panels with this robust outer profile. Meanwhile, the fused core within the squarish segments uses polystyrene or polyurethane to reinforce the thermal barrier. Vapours and liquids are stopped by this secondary perimeter, which results in a stable inner environment, one that’s cool and energy efficient.
