A complete line of pressurisation sets which allows control and efficiency, steadily maintaining constant pressure in a closed water loop     Alfa Laval manufactures and sells a complete line of pressurisation sets : the Pressosmart range. With a simple, unique design and very high reliability, these pressurisation sets allow control and efficiency, steadily maintaining constant pressure in a closed water loop. Pressurisation sets can be used in a very wide range of applications in heating, air conditioning and industrial fields where low temperature, high pressure, overheated or chilled water closed loop systems are being used as heating or cooling sources. When installed in a closed loop water system where temperature variations occur, the Pressosmart pressurisation set performs four main functions automatically : • Maintenance of a constant and steady pressure • Expansion • Filling-up • Disconnection
