Businesses feeling the heat over rising energy bills have been told they can trim up to a fifth of the cost of running refrigeration equipment by deploying cheap and effective technologies, such as more efficient appliances and energy recovery systems.
A new guide published today by the Carbon Trust claims refrigeration accounts for as much as 50 percent of energy costs for food processors and supermarkets -- a figure that can rise to 70 percent for small companies.
"Any business seeking to cut its costs should be looking at its energy bills," said Richard Rugg, director of delivery services at the Carbon Trust. "Savings of up to 20 percent are possible with simple low-cost steps. If your business uses refrigeration, it's an opportunity that's too good to miss."
The guide highlights how highly efficient display cabinets listed under the Enhanced Capital Allowance (ECA) scheme can use up to 30 percent less energy than a non-listed cabinet, while also enjoying considerable tax breaks.
Moreover, leaving doors open costs supermarkets up to £6 per hour for freezers, a cost that can be negated by using more air-tight systems.
Using an energy-saving "desuperheater" to recover heat lost from fridges can also reduce boiler energy consumption by up to 30 percent, it adds, while specially engineered chillers could save as much as £25,000 per year compared to a typical 800kW process chiller.
The Carbon Trust said that installing a defrost-on-demand technology saved £15,000 in energy costs for Evron Foods, a cold store operator in Craigavon, Northern Ireland, meaning payback on the initial investment took just over a year.
