The heat exchanger allows the thermal exchange between the refrigerating solution and the product (crushed grape, destalked grape or must). The exchanger consists of a bearing frame with tubular modules (pipes) fixed on it, which make up the concentric exchange units. The heat exchanger is entirely made of stainless-steel and provided with digital thermometers for controlling the ingoing and out-going temperature of product and refrigerant. On demand, the heat exchanger can be insulated and with spiralled pipes.Space saving multi-tubular heat exchangers are also available for the processing of clean wines and musts.The heat exchanger size is studied in accordance with the customer’s needs.
