‘Aquapoint APIII’ range of direct unvented under basin or over basin (wall mounted) electrically heated, enamel lined insulated steel storage cylinders. The cylinders are supplied with an expansion relief valve set at 6.0 bar. Maximum working pressure 5.5 bar. Maximum operating temperature 75°C.
Range of wall hung, gas fired, combination boilers providing domestic hot water via a plate heat exchanger. The primary circuit incorporates an integral expansion vessel and a pressure relief valve set at 3.0 bar. The product is supplied with a rigid pipe filling loop, followed by a separate isolation valve. The filling loop pipe attaches to the cold water inlet valve which incorporates a double check valve assembly (verified by test, suitable for backflow protection against Fluid Category 3) on the branch to the filling loop. The primary circuit includes an isolation valve on the flow and return and is also supplied with two loose 22mm compression isolation valves and a filter. Maximum working pressure of the primary circuit is 2.5 bar and the maximum supply pressure to the secondary circuit is 10.0 bar. Max operating temperature 65°C.
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.
Range of vertical multistage booster pumps, with stainless steel bodies and impellors. Maximum working pressure: See models Maximum working temperature 85°C.
Range of shower handsets with chrome plated ABS bodies incorporating NBR o rings. Maximum operating temperature 60°C.
