Factors that Contribute to Freezer and Coolroom Energy Efficiency
26 June 2017
Numerous written commentaries expertly describe subpar walk-in refrigeration units. They uncover poorly maintained freezers, highlight ongoing coolroom issues that haven’t been properly addressed, and generally provide a guide to improving energy efficiency within leaky refrigerated environments. As worthy as those deftly compiled guides undoubtedly are, they only ever talk about system flaws, not system efficiency. Today, we’re flipping that approach on its head by holding up a model of an energy efficient cooling setup. Illustrating the Ideal Coolroom Configuration An impeccably configured walk-in freezer isn’t affected by the opening of an accessway. A plastic curtain acts as a kind of […]

Common Causes of Failure in Clear Plastic Swing Doors and Plastic Strip Curtains
13 June 2017
Today, clear plastic swing doors and plastic strip curtains are considered a cold storage room staple. The space-segregating PVC panels prevent dirty air from circulating, they help cold storage areas to keep their goods cool, and also generally eliminate other zone-propagating invaders, including noise. There’s little that can go wrong with the tough plastic access points, although they are susceptible to the following site threats. Physical Impacts A sweep of a staff members’ hand pushes aside the panel. No damage is done, so the workflow continues. In point of fact, the workflow is optimised because there’s no waiting for a […]

How Do Door Closer Systems in Coolrooms and Freezers Work?
18 May 2017
Door closer systems use spring-loaded assemblies to hasten the sealing cycle. These are mechanically tensioned components, plus there are pneumatic and hydraulic variants available. To all appearances, the product looks like a plain hinge and its accompanying housing. On closer inspection, there’s some real fluid and mechanical muscle backing coolroom and freezer door closing mechanisms. Assures Threshold Continuity A strict binary configuration rules coolroom doors. That entryway is engineered to be either open or closed. When open, the catering worker quickly walks into the chilled enclosure, accesses the stored commodity, then he closes the door. If it didn’t close, there’d […]

Functions and Uses of Coolroom Warning Bells
08 May 2017
Alarm systems are employed when a sensor-equipped machine needs to catch a home occupant’s attention. They call out a warning so that we know a fire is spreading or carbon monoxide is silently filling a room. Coolroom warning bells satisfy a similar function. They exist to alert the kitchen staff of a failure, an event that’s threatening the chilled product. Here’s a peek into the functions and uses of these coolroom warning bells. Equips the Coolroom with a Voice A temperature management system is basically a feedback device. The temperature is set on a thermostat, a sensor records the thermal […]

What are Floor Guide Rollers for Coolrooms and Freezers?
24 April 2017
Door hardware kits introduce walk-in coolrooms and freezers to many curiously shaped components. There are spring-loaded mechanisms to close that final crucial gap and create a perfect seal. Additionally, there are plastic curtains to soften the interface between the outside environment and the chill inner chamber. Floor guide rollers are just another member of this vital mechanical sealing group. Here’s a walkthrough that illustrates the role of these ground-level guides. What are Floor Guide Rollers? Designed as seal-essential rolling door components, these guides, brackets, and wheels support heavy coolroom doors and move them along accurately established grooves. In other words, […]

Functions of Silicone and Mastic for Refrigeration (Coolrooms and Freezers)
11 April 2017
Mastic is a semi-solid paste, a sealant that’s commonly employed in many industrial and commercial settings. Importantly, this sealant can be formulated as a “non-skinning” product, but more on this property later. Meanwhile, a comparable silicone sealant exhibits similar properties. It’s flexible, highly temperature capable, and designed to quickly adhere surfaces. Neutral Cure Silicone Sealants The liquid rubber is pressed out of a tube by a caulking gun. Chemically neutral by design, the malleable compound lacks a plastic backbone. Instead, the inert silicon creates an elasticized barrier, an insulating glue that adheres while flexing. That’s an important quality for a […]

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 […]
