HFE Energy Optimising Soft Starter

This is the ideal retrofit energy optimising solution for Soft Starting single phase compressors such as those used in supermarket and restaurant refrigerators and can yield between 10 -32% 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 – the unit is ‘fit & forget’ and 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.

This product is perfect for use in the applications shown below:

  • Refrigeration Systems
  • Chillers
  • Conveyors
  • Heat Pump
  • Coolers
  • Oven Fans
  • Air Conditioners
    and many more

Features and Benefits

Energy Optimising
Reduces energy consumption when the chiller/compressor is not at full load by 10 – 18%. This reduces energy costs (and related cost) and reduces carbon emmisions (at the supply generation).

Torque Reduction
Mechanical and electrical stress reduction or elimination means compressors last longer and require less maintenance.

Ideal for Retrofit, Simple Installation
Quick and simple implementation means low cost install in existing equipment and rapid return on investment through energy and maintenance cost reduction

“Fit and Forget”
No maintenance time or associated cost.
