HES-E Economical Smart High Efficiency Circulator Pump
Description
HES-E series pumps are high-efficiency circulators, designed for heating systems. The pump features AUTO function which automatically adjusts the pump to system demands for optimal comfort and the lowest energy consumption as well as simple commissioning. It is the simplified version of HES series.
Suitable for:
- Commercial heating
- Commercial hot water recirculation
- Domestic hot water recirculation
- Domestic heating
- Industrial heating
Benefits
» Ready for Conversion according to Ecodesign Requirements for 2015(ErP) with EEI ≤ 0.23
» Providing energy savings and comfort level
» Automatic and continuous detection of optimal duty point by AUTO
» Automatic night setback function
» High safety – built-in electrical and thermal protection of the pump
» Self-venting pump housing
» Fault prompt function
» Low noise level
» Based on 500,000 times test in extreme conditions
