Gemini® Packaged Air-Handling Unit
40RLQ

Heat Pump, with Puron Advance™ Refrigerant

6 to 20 Nominal Tons

The Gemini® 40RLQ and 38AXQ series indoor air handlers and outdoor units provide a wide variety of heat pump options for your HVAC application needs. These units are designed for long dependable operation and maximum installation flexibility. All Gemini® 38AX Condensing Units and 40RL Fan Coils use environmentally sound Puron Advance® refrigerant. Together, they create a reliable split system that provides easy solutions to a wide range of commercial HVAC needs.

The 40RLQ 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 supplemental heating capability, the 40RL’s allow for field installed electric heaters, hot water coils, or steam coils.
