Back To Directory SectionsCAIO ranges of Indirect stainless steel insulated hot water storage cylinders with external expansion and copper pipework and fittings. The DHW circuit consists of a temperature and pressure relief valve set at 7.0 bar and 90°C, an inlet control group consisting of a pressure reducing valve adjustable between 2.7 and 3.3 bar, an expansion relief valve (SRV) set at 6.0 bar, a strainer and a check valve cartridge, verified by test (suitable for backflow protection against Fluid Category 2) also supplied with a tundish. Maximum supply pressure to the inlet control group 10.0 bar. Maximum working pressures - Primary circuit 6.0 bar, Secondary circuit 5.5 bar. Maximum operating temperature 65˚C.
Air source heat pump with a temperature and pressure relief valve (7.0 Bar) factory fitted. Maximum working pressure 5.5 bar. Maximum operating temperature 70°C.
Range of domestic stainless steel or coated carbon steel indirect unvented hot water storage cylinders and buffer tanks, incorporating a stainless-steel coil for connection to a heat pump circuit. The secondary circuit is factory fitted with a temperature and pressure relief valve (7.0 Bar @90°C) and an immersion heater. Maximum working pressures: Water storage tanks (ECO-ZR200S and EG-200CAIO): 5.5 bar. Buffer tank (ECO-ZR60 and ECO-ZR60S): 7.0 bar. Maximum operating temperature 70°C. The ECO-ZR60 and ECO-ZR60S models are to be used in a primary circuit only.
Excelsior Range of Direct and indirect unvented storage cylinders. The secondary circuit is factory fitted with a temperature and pressure relief valve set at 7.0 bar @ 90˚C. The product is supplied with an inlet control group (safety kit) consisting of a pressure reducing valve pre-set at 3.0 bar, strainer, an expansion relief valve set at 6.0 bar and a check valve cartridge (verified by test - suitable for backflow protection against Fluid Category 2). A tundish and expansion vessel are also provided Maximum working pressure: 5.5 Bar (All Circuits) Maximum operating temperature 90.0°C
Range of unvented heat pump storage cylinders which consist of an air-source heat pump sitting on top of the tank with either no internal coil (model numbers ending without S) or a factory fitted single internal coil (model numbers ending with S). The secondary circuit is factory fitted with a temperature and pressure relief valve set at 7.0 bar @ 90˚C and an stainless steel immersion heater and titanium alloy anode. The product is not supplied with an inlet control group (safety kit). Maximum operating temperature 70°C. Maximum working pressure (primary & secondary circuit) 5.5 bar.
