Refrigeration systems account for around 20% of the world’s energy consumption. We have considerable practical experience to demonstrate that here is real potential to achieve dramatic reductions in energy costs -improve equipment performance and reliability -at the same time providing more accurate control of the temperature of stored food products.

The Problem.
When it comes to businesses such as supermarkets, restaurants and hospitals, refrigeration is not a luxury but a necessity. These necessities come at a price and with soaring electricity prices and a global climate change, refrigeration costs continue to increase year after year.The problem businesses face with modern commercial refrigeration is that they can waste up to 30% of their energy and run 50% more cycles than necessary trying to do the job they are designed for, namely; lowering the temperature of a substance and then maintain that temperature on a continual basis.

Why does refrigeration waste energy?
To understand the underlying problem we need to look at the basics of how the refrigeration process works… It begins with the compressor switching on and ends by bringing down the air temperature until the desired setting is met. This process is called a ‘cycle’ and in some cases a cycle can occur as many as 20 times per hour.

A refrigeration thermostat monitors circulating air temperature in order to decide when to switch on and off. However, circulating air temperature rises far more quickly than food temperature and as a result, the refrigeration unit works harder than necessary to maintain stored products at the required temperature. This in turn leads to excessive electricity consumption and undue wear and tear on the equipment.As an example, consider what happens when you open your refrigerator to take out a product. The door is only open for a brief period of time but once the door is closed what invariably happens? Click… the compressor starts and the refrigeration cycle begins. This is because the air temperature has risen even though the product temperature has not altered! This results in unnecessary wasted energy consumption and higher bills.

Install CUES… an ingenious product from BEST.  Initially developed to improve food safety standards and now, backed with a NSF seal of approval, is proven as an invaluable energy saver.


Simply by regulating the refrigeration cycle based upon food temperature rather than air temperature – thereby
maintaining food at the correct temperature and eliminating wastage. Installed in conjunction with CUES Standard
the existing thermostat sensor which energises the compressor, CUES will significantly reduce the frequency of the refrigeration cycles which will now be based on food temperature rather than more rapidly fluctuating air temperature. The results? Up to a huge 30% reduction in energy costs and some times even greater.

So if you think that reducing excess energy consumption, saving money and reducing your maintenance costs along with increasing the life expectancy of your refrigeration equipment is something that makes sound, commercial sense – then the CUES from BEST is the perfect solution.
