OMAHA, Neb. — As analyzed and reported by California’s Emerging Technologies Coordinating Council, Bes-Tech announced that Southern California Edison tested the company’s Digi-RTU® HVAC Rooftop Optimization Kit and found an energy reduction of up to 40 percent kW and 50 percent kWh.

The Digi-RTU is a control kit designed to improve the energy efficiency of a rooftop HVAC unit. The control modulates the rooftop unit capacity to match the dynamic nature of the building cooling or heating loads by regulating both the supply air fan and compressor speeds. As a result, energy waste is minimized and indoor comfort improved.

Bes-Tech said the control can be used on all commercial and industrial rooftop HVAC units of between 3 to 30 tons. It can be configured for operation using a conventional programmable thermostat or integrated into the existing building automation system.

According to the company, the Digi-RTU provides continuous comfortable room temperature and humidity levels, reduces compressor cycling, and extends rooftop unit service life. It also satisfies ASHRAE Standard 62.1 and California Title 24 requirements.
