About Rawal Devices
Rawal Devices is the pioneer and category creator behind APR Control, founded in 1993 on Davis Rawal's patent. More than 100,000 valves installed since 1993, APR Control UL Listed, and real engineers answering the phone.
Our Story
Rawal Devices is the pioneer and category creator behind APR Control, founded in 1993 on Davis Rawal's patent, and we design and manufacture our products in-house in Woburn, Massachusetts. We did not adapt an existing product to capacity control: we created the approach, and we have been refining it and standing behind it in the field since 1993.
What we make
APR Control by Rawal Devices: continuous capacity modulation for oversized and staged DX HVAC. Two products, each with a distinct job: the mechanical APR Control and the electronic APR‑E Valve both add continuous capacity modulation to standard DX HVAC, so oversized and staged equipment runs at part load instead of short cycling.
Why Rawal Devices
Heritage is only half of it. The other half is that when you call, a real engineer answers and helps you size and apply the product to your equipment. The same people who designed it are the ones on the phone. A category we created plus live human technical support: that is who we are.
Talk to the people who created the category
Tell us your equipment and what it is doing. The engineers who created continuous capacity modulation size it themselves, on us, with a one-business-day response.
