Application Examples

The APR Control can help improve system performance across a wide rang of HVAC applications.
Here you will find examples of various technical applications where the APR Control ensures proper temperature and humidity control for greater comfort, indoor air quality and energy efficient performance, while providing an excellent return on your investment!

Oversized Air Conditioning Solution

Your typical air conditioning system and control sequence… Air conditioning systems are primarily on/off devices of a fixed capacity, controlled by the limits of the thermostat. A standard thermostat, when set at 72°F (with +/- 1°F range), will turn the air conditioning on at 73°F and cool the space, at… Read More

Humidity Control Solution

Air Conditioning isn’t about temperature control, it’s about removing humidity from the air. Dehumidification is arguably much more important in order to maintain a comfortable space! Without a properly sized air conditioning system, it’s going to be impossible to control the relative humidity in the space. Read More

APR Control Enhances System Reliability

A system that has the ability to modulate capacity also can provide better reliability and fewer operating problems. These often are related to stresses placed upon the system’s compressor. Short cycling, low airflow, and other system problems can easily be corrected with the APR control. As a result, the Rawal device can reduce call backs and warranty issues, even on new sys Read More
