Energy-saving -Operation

Speed-controlled EC-exhaust fan with negative pressure monitoring Hargassner use at the ECO-PK the energy-efficient EC-exhaust fans . The main advantage of this GreenTech EC-technology is the significantly higher efficiency rate of up to 90%. This saves energy and also electricity costs. The negative-pressure unit constantly measures the pressure conditions in the combustion chamber. The Lambda-Touchtronic uses this data to control the speed of the draught fan, thus keeping the negative pressure at an ideal level. This concept ensures combustion with minimal exhaust gas temperatures and therefore maximum efficiency.
