OASys Air Conditioner - Better than 40 Seer

Nature's Air Conditioner®

The California Energy Commission sponsored the development of the OASys SEER 40 Plus and achieved its goal of producing an enhanced energy efficient air conditioning system. OASys is a technological breakthrough in Indirect/Direct evaporative cooling. The key to OASys is a unique heat exchanger combined with a single pump/blower configuration. Unlike conventional air conditioning systems, which recirculate indoor air, OASys continuously conditions and delivers fresh outdoor air - the Outdoor Air System.

The OASys produces up to 3.5 tons of cooling while using less than 600 watts for an energy efficiency equivalent to better than 40 SEER. Switching to OASys cooling will result in an 80% energy savings without sacrificing comfort.

ETCC Emerging Technologies Coordinating Council Project Summary:
Two-stage or indirect-direct evaporative cooling technology offers the best opportunity for replacing air conditioning in California. The existing two-stage evaporative cooler on the market does not achieve the full potential of this technology. Previous lab testing has shown an achieved evaporative effectiveness of 88 to 98%. The OASys product, the result of a CEC PIER Program, appears to be able to achieve the technology potential. Lab and fields monitoring has indicated that the OASys technology can achieve evaporative effectiveness from 104 to 111%.
