Regular readers of our blog know that we believe in being prepared. It's important for businesses that rely on walk-in chillers and freezers to have a plan in place in case external refrigeration is ever required. Such a plan includes a working relationship with a provider like Icecool Trailers.
You might be wondering why such preparations are necessary. After all, there is no good way to anticipate when you might need emergency cold storage, right? Yes and no.
Below are four signs that indicate you might need temporary external refrigeration at some point in the near future. And by 'external refrigeration', we do not mean refrigerated van hire. We are referring to a freezer or fridge trailer parked outside your premises.
How to Tell if You Need Temporary Refrigeration
1. Ice Build-Up
Minimal ice build-up in a walk-in chiller is not completely unexpected. It is not good, but it's not unexpected. Ice build-up is almost always the result of one of two things. The first is condensation. If you're constantly opening and closing your unit on an especially hot day, condensation can form on the inside and then freeze.
The second possibility is a failing evaporator unit. This is definitely a problem. Complete failure could lead to excessive ice build-up that could go on to damage other parts of the cooling system.
2. Inconsistent or Increasing Temperatures
Commercial refrigerators and walk-in chillers are designed to maintain a consistent temperature over time. If you are noticing inconsistencies, your compressor could be failing. If the temperature inside one of your units continues to rise even though you're turning down the thermostat, you definitely have a problem. It's only a matter of time before the compressor stops working altogether.
3. Strange Noises
Strange noises are never a good sign for refrigeration equipment. If yours rattles, squeaks, thumps, or makes crackling sounds, your unit could be on its way to catastrophic failure. Never ignore strange sounds emanating from your fridges and freezers.
4. Strange Smells
Last but not least are strange smells. They come in all varieties, by the way. You could smell rotting food as a result of inconsistent temperature control. This is a sure sign you have a problem. On the other hand, it might be something completely different.
If you smell something resembling an overheated car, it could indicate that refrigerant is leaking from the system. That's not only bad for the chiller, it's also bad for food items stored in the space. Leaking refrigerant is something that needs to be addressed right away.
The smell of burning oil or metal could indicate that mechanical parts in your unit are failing. This is another warning sign of potential failure.
Each of these four signs could be an indication that your refrigerator or freezer is about to go. You might be calling Icecool Trailers sooner than you think. Maybe now would be a good time to reach out and see what we have available – just in case. After all, it never hurts to be prepared.
