Energy Saving Tips for Coolrooms
27 March 2017
If a coolroom is eating into the company energy budget, an all in caps “Keep That Door Shut” sign works wonders. That sign can stay, but we’re going to add a little more potency to this energy savings plan by suggesting a few essential tips. Once armed with this information, every staff member will know exactly how to keep any walk-in cooler in optimal working condition. Protect Cabinet Gaskets Tough elastomers compress reliably when coolroom doors open and close. However, that dependable property wears down over time. Check the gaskets for cracks or signs of wear. Sometimes the seal is […]

Energy Saving Tips for Freezers
06 March 2017
Freezers are energy gluttons when they operate inefficiently. They work around-the-clock, so they painfully exaggerate those power consumption figures. The 24/7 refrigeration cycle is as it should be, of course, for there are perishable commodities stored inside the insulated cabinets. Inefficient workings, however, are not welcome in freezer equipment. Here are some useful energy saving tips for restoring workload balance to your freezer. Operational Transgressions Kitchen workers needs access to refrigerated food, but there’s really no excuse for keeping that insulation-critical seal broken for several minutes at a time. Incautiously opened freezer entryways account for around six percent of a […]

What is Temperature Mapping?
16 February 2017
Temperature mapping is a procedure that forms a dynamic, thermally-active picture of what’s taking place within a cooling unit. Generally speaking, we accomplish this process by placing special monitoring devices throughout the cooling enclosure. Then, as the data is collated, a mapped thermal image is produced, one that illustrates the location of any warm spots. Remedial action is the next step. Before that, though, we need our monitoring devices. Installing Data Logging Monitors Electronic monitors are first on our agenda. These devices measure localized temperature variances while creating a time-based log. Hours and days of data are recorded, with the […]

External Temperature Factors That Affect Coolrooms and Freezers
06 February 2017
Contemporary coolrooms are fully enclosed chambers. There’s real thermal seclusion here, except for that one conduit connecting the isolated enclosure to the outside. This is the air inlet channel, a conduit that reaches outside the system. Not to worry, there are filters in place to stop airborne contaminants in their dirty tracks. But what about the temperature of that air? Just how do external temperature factors affect coolrooms and freezers? It’s the Little Details In planning for the bigger issues, we can miss the smaller problems. A door seal is repaired, for instance, but the damaged door clasp goes unnoticed. […]

Biomedical Freezers and Refrigerators: What are they?
24 January 2017
Biomedical freezers and refrigerators are designed to keep blood, cell cultures, and other biomedical samples cool. More than this, they’re built to control multiple environmental domains, including the dryness and sterility levels inside the sealed chamber. In order to accomplish these demanding tasks, state-of-the-art cooling components are incorporated into each unit’s build. That’s a broad strokes description of a complex process, but where are the details? What gifts these clinically rated coolers with their sample-preserving credentials? The Reliability Factor Scores of marketable domestic and commercial appliances lower their interior temperatures with great efficiency, but that’s not enough in a clinical […]

The Necessity of Proper Gasketing for Maintenance of Walk-in Freezers
09 January 2017
We’ve touched briefly upon gaskets when discussing walk-in freezers, but now it’s time to properly study this system necessity. Join us as we hover a critical eye over sealing technology as it relates to walk-ins, the subzero realms that can’t preserve their arctic interiors without a leak deterring mechanism. The necessity of proper gasketing for the maintenance of walk-in freezers begins here and now with a visual inspection. Inspecting Gaskets for Damage Pliable extrusion act as an interface between the door, its frame, and the frosty space beyond. As such, it’s classed as a mechanically active product. Hinged doors close […]

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 […]
