The GEMINI 40RU and 38AU series indoor air handlers and outdoor units provide a wide variety of options for your HVAC application needs. Whether it’s first cost with the single circuit 38AUZ and 40RUA series or superior part load performance from two stages of cooling with the 38AUD and 40RUA series or year around energy savings with the 38AUQ heat pump and 40RUQ air handler series. These units are designed for long dependable operation whether it’s a rooftop or on-the-ground installation. All GEMINI 40RU and 38AU series units use environmentally sound Puron® refrigerant. Together, they create a reliable split system that provides easy solutions to a wide range of commercial HVAC needs.

The 40RUS indoor air handler contains a chilled water coil and may be interfaced into chilled water systems.

The 40RU series have a multi-position design that allows for vertical or horizontal installation with no modifications. Powerful fan systems allow easy adaptation to existing ductwork. For heating capability, the 40RU’s allow for field installed electric heaters, hot water coils, or steam coils.
