HFE energy saving soft starters are designed to control single phase AC motors. Operation is fully automatic, a low starting voltage is applied to the motor as soon as the supply is switched on. The internal automatic ramp control immediately takes over and raises the voltage progressively, causing the motor to accelerate smoothly. At the end of the ramp period, the motor is operated in Energy Saving mode and the HFE continuously regulates the voltage to match mechanical load. Energy consumption at light loads is considerably reduced, motor winding and case temperatures are lowered, motor life is extended, noise levels are reduced and Power Factor is improved.

This is the ideal retrofit energy optimising solution for Soft Starting single phase compressors such as those used in Supermarket refrigerators and chillers etc., and can yield between 10 -18% energy savings. It has a rugged tin lid construction and can be mounted easily next to the machine or control panel. Installation of the unit is quick and simple due to the 'two wires in, two wires out' design. The unit is 'fit and forget' is there is no maintenance for the user.

Offering advantages over simple energy optimisers for similar cost, HFE provides mechanical and electrical stress reduction or elimination and optimised energy consumption when a chiller/refrigerator compressor is not under load. The starting current is reduced, and smooth acceleration is applied to the load.
