Arrow Valves has launched an innovative automatic Pressurisation and Dosing Unit.
The Dose & Fill maintains the inhibitor level in a heating system after any make-up by injecting inhibitor according to the concentration set via the LCD digital display.
Maintaining the system water quality protects against blockages and perforations of aluminium heat exchangers and steel panel radiators, helping validate the manufacturers’ warranties. A clean, sludge-free system also improves energy efficiency, reducing heating costs.
Comprehensive BMS controls report faults prior to heating system shut down and c excess water usage — ideal for buildings dependent on reliable heating such as schools.
