See the APR Control for R-454B in Action:

Check out this video as our Senior Technical Engineer, Jason Santos, demonstrates the performance of the APR Control in our very own in-house demo R-454B heat pump. Jason takes the unit through 3 different load scenarios by adjusting the fan speed (Low, Medium, and High Fan Speeds). Using a probe kit and anemometer, we display exactly how the APR Control:

Modulates system capacity to match real-time demand
Maintains optimal suction pressure
Ensures proper superheat for compressor protection

Whether you’re an HVAC technician, contractor, engineer, distributor, or building owner, this video will show you how the APR Control can improve the performance, efficiency, and lifespan of your R-454B HVAC system.
