High efficiency electronic circulators
L stands for Low, E stands for Energy. The 2-pole permanent magnet synchronous motor with a power consumption from 4 Watt makes heating comfort and money saving possible at the same time.
|The high efficiency electronic circulator recognises changing demands from the heating system and automatically matches the speed to the actual heat demand. This guarantees optimum efficiency at minimum energy consumption at any time.|
|Switch on the automatic night setback at the touch of a button - the pump reduces its flow to a minimum, when the water temperature is considerably decreasing. Reheating the water in the morning is followed by an immediate stop of the night setback.|
|The new HZ-LE 401 and HZ-LE 601 high efficiency electronic circulators from VORTEX already meet the stringent requirements of the European ErP Directive 2009/125/EC, which comes into force in 2015 (Commission Regulation (EC) No 622/2012).|
The model HZ-LE 401 is one of the most efficient circulators and hits the “Best in Class” benchmark* easily (EEI ≤ 0.19). The higher powered HZ-LE 601 achieves an efficiency of EEI ≤ 0.22.
*The benchmark for the most efficient electronic circulators is
EEI ≤ 0.20. EEI = Energy Efficiency Index
