‘POD’ range of indirect and direct heat interface units providing space heating and instantaneous hot water. The heat transfer is generated via plate heat exchangers. The domestic hot water (DHW) circuit incorporates an adjustable temperature mixing valve. The indirect models incorporate an expansion vessel (on the CW inlet of the DHW circuit) and a pressure relief valve set at 3.0 bar (on the space heating circuit). The indirect models only are supplied with a temporary filling loop, which comprises of a stainless steel braided EPDM lined flexible hose assembly and a lever operated spherical valve for connection to the primary circuit. The angled cold water inlet incorporates an isolation valve and a branch to connect to the filling loop, which includes a double check valve assembly (verified by test, suitable for backflow protection against Fluid Category 3). Maximum working pressure for indirect units: Primary circuit: 16.0 bar. Space heating: 2.5 bar. Secondary circuit (DHW): 10.0 bar. Maximum working pressure for direct units: Primary circuit: 10.0 bar. Space heating: 10.0 bar. Secondary circuit (DHW): 10.0 bar. Maximum operating temperature for domestic hot water 65°C. Maximum operating temperature for central heating and primary circuit 85°C.
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.
Hydraulic block assembly comprising of a flow regulator, central heating pump assembly and a stainless-steel plate heat exchanger. Maximum working pressures: DHW circuit: 10.0 Bar Central heating circuit: 2.5 Bar Maximum operating temperature: DHW Circuit: 65.0°C Central heating circuit: 90.0°C
Range of commercial ice making machines with flow controlled via solenoid valve. Maximum working pressure 8 bar. Cold water use.
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 pressure transmitters with stainless steel bodies. Maximum working pressure 10.0 to 200.0 bar (please refer to model). Maximum operating temperature 100°C.
Range of brass (chrome plated) quick fit connectors. Maximum operating temperature 60°C
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.
