Arbe recently completed installation of a complete heat recovery system for a food factory. The remit was to design a hot water system that would recover heat from cold room refrigeration units which would be used to preheat water in a calorifier and thus reduce power usage on the refrigeration unit as the cooling fans would not need to be used
