SureStart, Single Phase Compressor Soft Starters for HVAC units and heat pumps
BriskHeat now has an easily installed, single-phase compressor soft starter for HVAC units and heat pumps. The single-phase soft starters increase the efficiency and longevity and reduces the in-rush current needed for compressors to start, minimizing potential damage to compressors from mechanical shock hard-setting current surges.
