Energy-saving circulation pumps , thanks to which energy consumption can be reduced by 80% compared to traditional circulation pumps. Delta HE 35-55 meet the benchmark for the most energy efficient circulator EEI <= 0.20.

With "One Touch" support, seven different power characteristics can be selected: four according to the principle of proportional pressure, three with a constant speed and a night temperature drop function.

The LED display shows the current power consumption, the selected characteristics and the night temperature drop function.

The task of the pump is to pump the coolant from the heat supply or cooling generator (boilers, heat pumps, solar systems, etc.) to the closers (radiators, fan coil units, underfloor heating, etc.).

They provide the following benefits:

• increase the overall efficiency of the system through electronic regulation;
• reduce system power consumption;
• significantly increase the service life of heat generators;
• protect the system from overheating and boiling;
• increase the comfort of using thermal systems.
