The APR Control is an external compressor unloader that reduces the compression ratio as it diverts refrigerant from the outlet of the compressor back to the suction inlet. As a continuous capacity modulation device, the APR Control externally unloads the compressor, thus reducing energy consumption of the system. Traditional hot gas bypass falsely loads the evaporator, thereby reducing the efficiency of the system. As an external compressor unloader, the APR Control is compliant with today's energy codes! The APR Control provides continuous capacity modulation and dehumidification for direct expansion air-conditioning (DX A/C) systems. In 1993, Davis Rawal invented and patented the APR Control. The APR Control has proven to be a reliable solution for many performance issues that arise from commonly oversized systems. The APR Control is a mechanical device that maintains suction pressure, allowing the system capacity to match the ever-changing load and space requirements.

Features & Benefits

• Unloads the Compressor
• Reduces the Compression Ratio of the Compressor
• Externally Unloads
• Reduces Power Consumption While Active
• Very Good Latent Performance
• Code Compliant
• The APR Control has the Ability to Modulate System Capacity to the Ever-Changing Load Conditions in the Space, While Eliminating or Significantly Reducing Excessive Cycling that Leads to a Rise in the Space Relative Humidity
