DCAC Air Cooler

Off-Grid DC Powered Air Cooling Save on total off-grid system cost with SunDanzer DC Air Coolers. These ultra high efficiency air coolers have exceptionally low energy consumption requiring smaller, less expensive power systems and low operating expense. High quality construction provides excellent reliability and long life.  A zero maintenance, brushless, microprocessor controlled DC motorcompressor operates on a wide variety of DC voltages, including direct connection to a PV array without batteries.

With variable speed compressor and state of the art heat exchangers, SunDanzer Air Cooling Systems provide outstanding economical and reliable operation. The Battery-Free (PV Direct) model, developed by NASA and licensed to SunDanzer, utilizes patented refrigeration technology in its design to optimize the refrigeration cycle and achieve ultra low energy consumption. Low energy consumption and very soft starting are the keys allowing SunDanzer Air Cooling to be cost effectively powered from solar, wind, fuel cells or batteries.

This technology affords air cooling in remote locations were it was previously unavailable or prohibitively expensive. Automatic, hybrid operation with AC generator mitigates fuel use and lowers maintenance costs. Fully instrumented with high and low pressure sensors and LCD user interface for diagnostics and repair
