American Public Power Association’s 2011 DEED Energy Innovator Award


Based on two pilot projects OPPD completed utilizing the Digital Heat Pump Optimizer Technology, OPPD, in connection with developer DTL Controls, undertook a project which integrated Digital Roof Top Unit (RTU) Optimizers into Rooftop Air Conditioners at a test manufacturing facility.

The typical RTU system consumes 30% -­ 40% more energy than needed and generally is equipped with a constant speed compressor and an over-sized fan system. Through the addition of a Digi-Rtu Optimizer, each air conditioning unit achieved a kW savings in the range of 25% -­ 60%. Compressor cycling diminished by up to 70% and occupant comfort within the test manufacturing facility was maintained. Download Bes-Tech’s RTU Brochure to find out more about this product.
