The Unique Electronic Filling Device (EFD) is a fully automatic, wall mounted sealed system filling unit for domestic and commercial heating and cooling systems.
A Pressure Logic™ microprocessor unit controls system pressure via Honeywell transducers with continuous system status indicated on a liquid crystal display. A multi function control panel accesses all control functions.
The WRAS approved EFD fulfils three roles: backflow preventor, filling device & pressurisation manager, all within one wall mounted compact unit. No pumps or storage tanks - the EFD uses mains cold water to fill and maintain pressure. Backflow prevention is achieved by using a patented principle to generate an air gap between heating/chiller system and cold water main.
