The Dual Cool product combines an evaporative condenser air pre-cooler and a ventilation air pre-cooling coil through which cool water is pumped from the evaporative pre-cooler sump. Dual Cool systems are designed for addition to standard packaged rooftop cooling units. The Dual Cool system includes a microprocessor-based controller that activates the circulating pump and the condenser fan in response to outdoor and indoor conditions.
