The Blizzard LBC Range Freezer Gastronorm Counter has a coved upstand as standard and rounded internal corners for easy cleaning. It has self closing doors with stay open facility, and an energy efficient Blue Line Controller. For the energy conscious who want to reduce energy bills, the Blue Line range delivers superb reductions in energy use compared to standard units using a unique Dixell controller. HOW DOES THE BLUELINE CONTROLLER WORK? The BLUELINE controller has been programmed with algorithms to reduce the amount of starts the compressor needs to make in relation to its usage. Most electrical energy is used on a refrigerated cabinet when a compressor starts, so by reducing the number of starts it reduces the energy usage. This does not affect the storage temperature of the product.
