Energy Efficiency
The APR Control provides alternative design strategies that have been proven to reduce total power consumption of a new or existing system installation / design.
Optimization is only possible with the power of DX modulation. Modulation to match changing load conditions reduces or eliminates cycling. There is a wide range of studies recognizing that increasing the runtime by just 4 minutes (from 5 to 9 minutes after start) can improve the efficiency up to 17% Read More
The concept of Optimization has become prevalent in the HVAC industry. It is an agreed upon term that refers to controlling the HVAC systems to provide the necessary amount of cooling to maintain building comfort demands at energy efficient levels to utilize the least amount of power consumption.

Rawal Devices contracted with Underwriters Laboratories’ HVAC Testing Facility to conduct a third-party evaluation of the APR Control performance against a standard DX cooling system and a system with a simple hot gas bypass during similar part-load demands. Read More
Adjusting the APR Control Are there any adjustments that need to be made after installing the APR Control? The Rawal Devices APR Control has been known around the HVAC industry as a “set it and forget it” solution. For most standard DX comfort cooling applications, the APR typically does not… Read More
