The Rawal Devices Team is excited to share our proven success with the APR Control for R-454B!
The team has performed extensive testing in-house on our own demo unit made for testing and display purposes. We’ve also worked with major equipment manufacturers who have tested, approved, and begun incorporating the APR Control into their R-454B equipment lines.
Major manufacturers love the APR Control for R-454B!
We’ve created the video below to provide reassurance that the APR Control will work on your equipment. Keep in mind, we’ve been in this business for 30+ years and have always produced a reliable solution that can be depended upon by the HVAC industry.
Rawal Devices would never risk our reputation by putting out a product when we weren’t 100% confident in its performance!
Watch the Video
Check out the video below showcasing the APR Control for R-454B featuring our very own Senior Technical Engineer, Jason Santos. In this video, we are demonstrating the performance of the APR Control for R-454B across various scenarios.
As you can see, the video shows:
- Stable superheat
- Stable suction pressure
- Stable saturated suction temperature
- Capacity modulation

Trend Data
To evaluate the performance of the APR Control with R-454B, we conducted a series of tests in our shop. The R-454B test unit was operated both with and without the APR Control active for successive 90-minute tests at various airflow rates: high speed (2000 CFM), medium speed (1450 CFM), and low speed (1200 CFM). Using a Fieldpiece Complete Job Link Probe Kit, we measured capacity (BTUs), suction pressure, and superheat. Airflow readings were obtained with a Testo Digital Anemometer. The results of these tests are presented below.

You’ll see that in all of our hours of testing the APR Control for R-454B:
- Maintains suction pressure
- Modulates capacity (as our APRs for R-410A have)
- Keeps superheat steady at an ideal 18-20°F!
