The Gemini® 40RUQ Packaged Air-Handling Unit redefines adaptability and reliability for commercial HVAC solutions. Engineered for energy-efficient cooling, it uses environmentally conscious Puron® refrigerant (R-410A). Its flexible multi-position design supports horizontal and vertical installation without modification, ensuring easy adaptation to unique systems. Boasting powerful belt-driven centrifugal fans and advanced coil technology, the 40RUQ guarantees optimal airflow and consistent indoor air quality. With robust galvanized steel casing, cleanable insulation treated with antimicrobial agents and compatibility with Carrier’s 38AU condensing units, it delivers cooling precision paired with reliable performance.
Precision thermostatic expansion valve (TXV) ensures efficient cooling control, automatic reset motor overload protection enhances durability and it’s constructed to UL 1995 safety standards for long-term reliability.
Flexible vertical or horizontal installation can accommodate various layouts. A single-point electrical power connection simplifies wiring requirements. Adjustable condensate drain pans allow for tailored configurations.
Removable side panels provide quick access for simple servicing or inspections.
Permanently lubricated motor bearings reduce maintenance demands in the long term and filter replacement is effortless with integrated slide-out retainers.
The Gemini® 40RU and 38AU series indoor air handlers and outdoor units are designed for reliable rooftop or ground installation and all models use Puron® refrigerant.
