Designed to provide a semi-instantaneous supply of hot water in blocks of flats, hospitals, nursing homes, sports halls and similar large buildings, the AquaStore range from Alfa Laval helps protect against limescale build-up and also helps to reduce the risk of Legionella growth while delivering hot water, on demand, precisely when and where it is needed. The AquaStore is modular in concept and is delivered as a complete unit. At its core is a compact Alfa Laval heat exchanger which heats the incoming water to the pre-set temperature. The unit includes a range of controls and fail safe features that enhance security and user-safety including an anti-bacteria program, economy setting, auto test function and the ability to control temperature to avoid thermal shocks and inhibit scaling.
