Cooling Only, with Puron® Refrigerant (R-410A)
6 to 30 Tons
The Gemini® 40RU and 38AU series indoor air handlers and outdoor units provide a wide variety of options for your HVAC application needs. These units are designed for long dependable operation whether it’s a rooftop or on-the-ground installation. All Gemini® 38AU Condensing Units and 40RU Fan Coils 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 40RU series indoor air handler contains a chilled water coil and may be interfaced into chilled water systems. The 40RU series has 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.
