Electronically controlled heat interface units (HIU) with twin stainless-steel plate heat exchangers providing space heating and instantaneous hot water. The cold inlet supply to the plate heat exchanger incorporates an isolation valve. The space heating circuit incorporates an expansion vessel and a pressure relief valve (set at 3.0 bar). The inlet and outlet of all circuits incorporates lever operated spherical valves with brass bodies. 274.xx9x.696 models all have the following additional items over the 274.xx1x.696 models: Heatmeter on the primary circuit, a flushing bypass between the primary and space heating circuits and a safety relief valve (set at 10.0 bar) on the cold supply to the heat exchanger of the domestic hot water circuit. Maximum working pressures and operating temperatures: Primary: 16.0 bar and 90˚C. Domestic hot water (DHW): 9.5 bar and 60˚C. Secondary (space heating): 2.5 bar and 85˚C.
Range of water meters with plastic bodies and EPDM ‘O’-rings. The inlets incorporate a plastic strainer. Maximum working pressure 10.0 bar. Cold water use only.
Range of shock arrestors with carbon steel or stainless steel bodies (available in various external surface finishes) incorporating Bromobutyl (BIIR) membranes. Maximum working pressure 10.0 bar. Cold water use only.
Range of shock arrestors with stainless steel bodies incorporating Bromobutyl (BIIR) membranes. Maximum working pressure 10.0 bar. Cold water use only.
Air break to drain, incorporating brass bodies with a grey epoxy powder coating. Maximum operating temperature 60°C.
Impeller with plastic body for insertion into specifically dimensioned bores. Maximum operating temperature 70°C.
Wall mounted chrome plated brass elbow fitting. Maximum working pressure 5.0 bar. Maximum operating temperature 70°C.
Hygienic flush box providing a timed flush facility. The supply is via a single check valve cartridge however, the complete product has not been fully tested to demonstrate it provides backflow protection, flow sensor, spherical ball valve and strainer. The products incorporate a type `AB` airgap (verified by test - suitable for backflow protection against fluid category 5). The units have multiple interface user functions for timed flush, wireless technology and data storage. Maximum working pressure 10.0 bar. Maximum operating temperature 60°C.
Maincor Manifold having a brushed chrome plated body with 2 ,3 or 4 ports each with an isolation valve with red or blue indicators for hot and cold feeds. Supplied with a blanking plug and nut. Maximum working pressure 6.0 bar. Maximum operating temperature 75°C.
Pent-A-Boost domestic break tank and booster set incorporating a single or dual pump stage pump set assembly and break cistern (incorporating an AG air gap arrangement). Inlet level sensors control the water supply via solenoid valves with inline strainers fitted (see manufacturers data sheet for optional arrangements). The unit also incorporates an expansion vessel. Flow from the break tank is via a single check valve suitable for fluid category 2 to a booster pump arrangement (see manufacturers data sheet for optional arrangements). Maximum working pressure 10 bar. Cold water use only.
