AquaCompact is a compact, pre-assembled and semi-instantaneous system for district or local heating applications. It consists of a charging kit mounted onto an AquaTank in stainless steel or enamel coating.     Since 1923 Alfa Laval has actively been engaged in water heating and has become a leading manufacturer and supplier in this field. AquaCompact replaces Bio and System D in the range of semi- instantaneous systems, adding more features to a system used in several countries in district heating or local heating applications. Because requirements are different from one application to another, AquaCompact is flexible and is available with plates and gaskets, copper brazed and even AlfaNova, the 100% stainless steel heat exchanger from Alfa Laval.
