4 pole motor- Double head circulator - Pumps are of the canned rotor type, meaning that the pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. - Stainless steel bearing plate and rotor cladding - AutoAdapt proportional pressure control - FlowAdapt and FlowLimit used in systems where a flow limitation is required - Intuitive user interface with TFT display - Constant pressure control - Constant temperature control - Built in differential pressure and temperature sensor - Constant curve duty - Maximum or minimum curve duty - Automatic Night Setback - Internal motor protection - Heat energy meter - Work log history - Insulating shells supplied with single head pumps for heating systems - Large temperature range where the liquid temperature and the ambient temperature are independent of each other
