Range of pump inverters with plastic bodies, NBR rubber and EPDM rubber seals and ‘O’-rings. The products incorporate an inline resilient trim non-return valve. Maximum working pressure 13.0 bar. Cold water use only.
Range of concealed thermostatic mixing valves with DZR brass bodies incorporating a thermostatic cartridge controlling the temperature. The inlets incorporate asingle check valve cartridges, however, the complete product has not been fully tested to demonstrate it provides backflow protection Maximum working pressure 10.0 bar. Maximum operating temperature 60°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.
‘e-SH’ range of centrifugal booster pumps with a blue polymer coated stainless steel body, stainless steel impeller and EPDM ‘O’-rings. Maximum working pressure 12.0 bar. Cold water use only.
Range of cold water in tank booster sets incorporating an ‘AG’ air gap, consisting of a GRP water storage cistern incorporating a float operated inlet valve, with a copper float and submersible pump or pumps (depending on model). The products incorporate an externally mounted stainless-steel manifold with servicing valve(s), expansion vessel, pressure gauge and a digital control panel. The pumps are connected to the external components via a discharge assembly of internal pipework including an in-line non-verifiable single check valve assembly (suitable for backflow prevention of Fluid Category 2). Maximum working pressure 10.0 bar. Cold water use only.
