Petra Evaporative Condenser Rooftop Package Unit with Hermetic Scroll Compressors
Differentiating from an air-cooled version that rejects heat to an AHRI 95°F ambient temperature, Evaporative condensers use a network of sprinkle cooling nozzles to spray water over the condenser coil that evaporates and cools the condenser air down toward a typical AHRI ambient wet bulb temperature of 75°F
This will result in rejecting heat to colder temperatures and thus, operating at a lower condensing temperature, which leads to lower compressor work and energy. In such operating conditions, evaporative condensing units operate at a lower condensing temperature and results in consuming 30–40% less electricity than comparable air-cooled units, especially at full load design conditions
Savings associated with evaporative Condensers lower energy consumption translates into lower electrical bills depending on the kW/Hr consumption rate in the area. Adding to the evaporative condenser savings, Petra offers multiple other cost effective and energy saving solutions that can contribute to an additional 15-25% energy saving
