During part-load or non-design day conditions or with lower airflow, you’re going to have less total heat content across the evaporator coil compared to your compressor capacity. Having enough heat content in the air entering the evaporator is critical to prevent Evaporator Freezing and Liquid Slugging or Floodback.
The APR Control’s ability to provide variable capacity control through mechanical means allows your system to match capacity of your equipment to the total heat load across the evaporator coil.
Rawal Devices’ APR Control can eliminate or prevent common problems associated with DX cooling – including eliminating Evaporator Coil Freezing and Liquid Slugging!
As a result, APR Control reduces downtime from labor-intensive service calls and costly warranty issues, make the APR Control a very cost-effective solution for problems occurring on you existing equipment and even on new systems!
