These pumps have built-in inverters linked to motor technology that has won energy-savings awards in Switzerland and Germany. This technology is now applied to pumps up to 65 mm bore, giving flow rates suitable for boilers up to 1000 kW with a difference of 20 K between flow and return temperatures.
There are six models with flow rates up to 12 l/s. They adapt automatically to variable flow rates and system resistance. For example, the 65 mm-bore pump modulates from 515 W to 50 W.
These pumps qualify for Enhanced Capital Allowances.
