“Optimum Control Technologies is actively involved in LIVE energy monitoring of the various elements of electricity use in Supermarkets. One of the age old problems has been the temperature variations in supermarkets caused by ‘spillage’ of cold air from chiller and freezer cabinets. We knew the solution was to use fans to mix the cold and warmer air. The problem was how to do this safely and unobtrusively – we had looked at a number of alternative fans – but they presented safety and noise problems.
We then discovered the Airius range of purpose built fan units – designed specifically for supermarkets. We were cautious as always and decided to run a limited trial – the results were amazing and defied all the sceptics: A) Customers’ noted the improvement in cold aisle temperatures immediately (it had been a regular cause of complaint), B) Temperatures throughout the store became more balanced without making a single change to the air conditioning settings, C) They had no visual impact – even with a
relatively low ceiling height, D) They did NOT have any impact on refrigeration running costs despite many predictions they would – the reason we know this is because we are measuring live the running costs of the refrigeration system”.
