The Archergas� GC Universal Modern produces a maximum head of just over 7 meters and is a pulse width modulating replacement circulator head, as well as being able to fit many integrated circulators it can also be used on standalone circulators like the UPS3, UPM3, UPM4 and the ALPHA2 GO. As with all Archergas circulators, it is fully ERP compliant with an impressive energy efficiency index rating of less than 0.20. The GCM15� is suitable for boilers, radiators, underfloor heating, cooling, solar, recirculation (non-potable) and air source heat pump systems. Archergas quality focused approach to manufacturing and use of high end component materials, this circulator is resistant to condensation, corrosion, high pressure and high temperatures.It also comes with a 3 year guarantee and can be used as a head replacement for a large number of integrated circulators as well as modern standalones and the ALPHA2 GO, Specification:Part Number: GCM15Maximum Head: 7 MetersMaximum Flow Rate: 65 Litres Per MinuteMaximum System Pressure: 10 BarEnergy Efficiency Index Rating (EEI): ? 0.20CE/UKCA Approved: YesSpeed Control: 6 ModesProtection Class: IP44Temperature Class: TF95�CInsulation Class: FSupplied With: Rubber Washers x2Material: Cast IronColour: Royal BlueWeight: 1.4kg
