Providing continuous capacity modulation for HVAC/R DX systems since 1993 · 100,000+ valves installed in the field

Facility Managers

See how facilities like yours use Rawal Devices' technology

HVAC equipment without capacity modulation will inevitably short cycle; this can lead to humidity problems, occupant complaints, higher energy consumption, and unnecessary wear on critical equipment. Rawal Devices helps facility managers get more from the systems they already own by improving part-load operation, extending equipment life, and enhancing comfort, all without replacing existing equipment.

Or start by what you need

Why facilities managers choose APR Control

  • Reliability without a capital replacement project
  • Comfort and humidity your tenants and occupants actually feel
  • Fewer failures: 77% fewer compressor starts, zero failures since install (Independent Field Study)
  • Avoid the cycling wear that drives compressors to fail early, and the premature $3,000 to $15,000+ installed compressor replacement that comes with it

“I have been installing the Rawal APR valves for over 20 years plus and never had an issue.”
