Pressosmart Pressurisation set 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 Operating principle When water temperature rises: The internal pressure of the closed loop water system increases until it exceeds the pressure control valve setting value, which then opens and lets water flow back to the open expansion vessel. When water temperature decreases: The closed loop water system internal pressure falls until it reaches the pressure controller set point which then activates the pump(s). Main components A pressurisation set of the Pressosmart range consists of two parts delivered separately that the contractor has to reassemble together on site: A ‘‘pump module’’ with a painted base frame fitted with: - One or two pumps (depending on model) - One or two pressure control valves (depending on model) - A set of black steel connecting pipes - An electronic pressure transducer (or pressure switches) - The electrical panel including the pressure controller, contactors and overload protections for the pump motors A PPH (polypropylene) open expansion vessel fitted with: - A drain port - An overflow port - A port for connecting the automatic fill-up solenoid valve (delivered loose – 230V / 1Ph / 50 Hz coil) - Two ports for fitting the level control float devices - Two ports for connection of the pump module - A removable top cover enabling internal inspection of the vessel and introduction of chemical treatment products
