Range of wall mounted, gas-fired, condensing combination boilers providing domestic hot water via a plate heat exchanger. The pressurised central heating system incorporates an expansion vessel and a pressure relief valve set at 3.0 bar. The inlets to the domestic hot water and primary circuits each have a screwdriver operated angled spherical valve. Both include a ½” BSP (M) connection for a filling link. The Greenstar CDi models only are supplied with an integral charging link (CAB device) verified by test (suitable for backflow protection against Fluid Category 3). Maximum working pressure of the primary circuit is 2.5 bar. Maximum working pressure of the secondary circuit is 10.0 bar. Maximum operating temperature of primary circuit is 82°C. Maximum operating temperature of secondary circuit is 60°C.
Range of commercial ice making machines with flow controlled via solenoid valve. Maximum working pressure 8 bar. Cold water use.
‘RSM’ range of ultrasonic water meters with blue epoxy coated ductile iron bodies, stainless steel transducer and EPDM ‘O’-rings. Maximum working pressure 16.0 bar. Maximum operating temperature 50°C.
Range of water meters with blue epoxy coated iron bodies and EPDM ‘O’-rings. Maximum working pressure 16.0 bar. Maximum operating temperature 85°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 multistage pumps with brass suction and discharge bodies, stainless steel housing, shaft and impeller, and EPDM ‘O’-rings and seals. Maximum working pressure: 6.0 bar (46553 - Stuart CH 4-30 & 46554 - Stuart CH 4-40 models) or 9.0 bar (46555 - Stuart CH 4-50 &46556 - Stuart CH 4-60 models). Maximum operating temperature 65°C.
Range of booster pumps with stainless steel bodies, plastic impellers, and NBR ‘O’-rings. The products incorporate a temperature sensor, pressure sensor, pressure vessel and a non-return valve integral to the pump chamber. Maximum working pressure 6.5 bar. Maximum operating temperature 75°C.
Range of brushless DC centrifugal pumps with a plastic body. Maximum working pressure 1.0 Bar. Maximum operating temperature 70°C.
Range of single and twin shower booster pumps with brass bodies, DZR brass impellers, NBR ‘O’-ring and EPDM seals. Maximum working pressure 6.0 bar. Maximum operating temperature 60°C.
Ranges of overhead shower outlets with brass bodies, chrome plated plastic shower handsets, shower sets and shower kits. The shower sets comprise of a chrome plated plastic shower handset and shower hose. The shower kits comprise of a chrome plated plastic shower handset, brass wall elbow and either stainless steel interlocked, or PVC coated, shower hoses. The inlets of the shower handsets incorporate a plastic flow regulator at the inlet. Shower kits with ½” (M) inlets are also supplied with a brass wall elbow which incorporate a plastic flow regulator and an approved single check valve cartridge (however, the complete product has not been fully tested to demonstrate it provides backflow protection). Maximum operating temperature 60°C.
