AquaMicro is Alfa Laval’s latest product for the district heating market; a self-contained sub-station designed for apartments and ready for connection to a suitable district-heating network.
Hot water from the district heating system is used to heat the water in the apartment indirectly via a plate heat exchanger, equipped with acid-resistant stainless steel plates. Since the water is heated as and when required, the hot water is always as fresh as the incoming, cold water.
