You may think that choosing a walk-in cooler is a very minor detail to your business, but to Supermarket Services Company Inc. it is a big deal because this company is known for always committing to placing workmanship and quality first - which is why they are numero uno in the business of manufacturing walk-in coolers

The Condenser Unit & the Thermostat The thermostat is what actually controls the temperature in a walk-in cooler. As soon as the temperature inside the unit begins to rise above the temperature that the thermostat is set at, then the condenser unit immediately switches on and begins a new cooling cycle. Air is pulled inside the cooler and over the condenser by the fans. The coolant present inside the coils immediately removes the heat from the air as the air passes over them. The already cooled air then moves out the back of the cooling unit, and it is a little colder than when it was pulled in. The process will continue until the temperature of the air either colder or simply matches the temperature on the thermostat. During the cooling cycle, the coolant in the condenser coils is regularly pumped; this will make sure that the coolant will not heat up too much before it cools down again.

There is also another cycle that will ensure that the condenser does not freeze and become all covered in frost and ice. So, if the temperature falls way too low (typically around 35 degrees F), the fans will then start again; this time, without the coolant in the coils cycling through. This will slowly warm up the condenser coils and the temperature will begin to rise. This defrosting cycle will cease when the temperature inside the unit is right back within the appropriate range.
