DheyTécnica’ Energy Recovery System heats drinking water to be used in the refrigerator at practically no cost, taking advantage of the thermal energy coming from the cooking and drying processes of the by-product processing factory. The equipment can heat drinking water between 45°C and 90°C, secondarily condensates part of the process gases, reducing the level of odors as a primary gas treatment equipment. The recovery system is made up of a tube shell heat exchanger and a hot water storage tank, both with automatic controls managing the system.
