Rheem 4 Ton Air Handler 21" Wide W/ R-454B Sensor

RH2TY4821STANNJ - Endeavor® Line Air Handler

Key Features:

• Quiet Operation: Cabinet construction with 1.0 inch of foil-faced insulation ensures quieter sound characteristics.

• Aluminum Indoor Coil Design: Constructed with aluminum fins bonded to internally grooved aluminum tubing for enhanced corrosion resistance.

• Versatile 4-Way Convertible Compact Design: Allows for upflow, downflow, horizontal left, and horizontal right applications, even in compact spaces.

• Rugged Steel, Compact Cabinet Construction: Designed for added strength and versatility.

• Less than 2% Cabinet Air Leakage at 1-inch H2O: Tested in accordance with ASHRAE Standard 193 to ensure minimal air leakage.

• Designing for Sustainability with Low GWP: Utilizes R-454B refrigerant with a global warming potential (GWP) limit of 700, resulting in a 78% lower GWP than previous-generation refrigerants, aligning with 2025 Environmental Protection Agency (EPA) requirements.

• PlusOne® Refrigerant Detection System™: Integrated, patented design featuring the A2L sensor and mitigation board, offering easier commissioning with a single component and simplified wiring configuration, compatibility with any 24V thermostat application, and system protection by automatically pausing outdoor unit operation if excess refrigerant is detected.
