Permanent filling/ pressurisation device for primary heating and chilled water closed circuits in domestic and non-domestic premises. The mains and closed circuit system pressures are continuously checked by two pressure sensors and their differential monitored by microprocessors. In the event of a fall in system pressure, and only if the mains pressure is adequate, a solenoid valve operates to allow water into the system. At all other times a second solenoid valve drains the fill chamber to waste, via tundish (meeting the requirements of an air gap to drain), and allowing air to be admitted via an automatic air vent to create an atmospheric disconnection across the transfer chamber. Maximum working pressure 6.0 Bar. Cold water use only.
