In producing their popular frozen baked goods, the traditional company Back & Frost uses only the finest ingredients – and enormous amounts of cold. Up until now, they have relied exclusively on conventional compressor cooling systems to satisfy this demand. With the recent purchase of a combined heat and power plant (CHP) and to decrease the demand placed on their compressor systems, the company has decided to use eco-friendly adsorption cooling systems from InvenSor.

Adsorption chillers generate cold by using the waste heat produced by combined heat and power plants (CHPs) and other machines as source of energy to drive the cooling process, operating according to the principle of adsorption. Two sub processes alternate with one another in the chiller, thereby achieving a virtually continuous cooling capacity. In May 2017 the ADsorption cooling systems were put into operation. Since then, they’ve been used to cool the condenser for the compressor systems, which has allowed an increase in the deep freeze unit’s efficiency and recooler capacity, since an additional recooler provides waste heat from the adsorption chillers to the environment.
