• HiPOR™ (High-Pressure Oil Return) Oil is returned to the compressor through a separate . inlet pipe, ensuring that compressor energy is used to compress refrigerant only. • Smart Oil Control. Eliminates timed oil-return cycles and takes hours . off of the time required to return oil compared to . systems that use a timed oil-recovery cycle.
