What is the difference between the APR Control and traditional hot gas bypass?
The APR Control provides continuous capacity modulation on direct expansion air conditioning and refrigeration systems. Contractors, Distributors, and Engineers referred to the APR Control as hot gas bypass because it was the easiest way to remember and explain application use. However, the APR Control is NOT hot gas bypass! The APR Control unloads the compressor and hot gas bypass loads the evaporator.
