4 Ton Rheem Two Stage R454B Air Handler RH2TY4821STANNJ
 
RH2TY Constant Torque Motor (ECM)
Refrigerant Type: R-454B

Features and Benefits
. Quiet Operation: Provided by a cabinet construction with 1.0 inch of foil faced insulation for quieter sound characteristics

. Aluminum Indoor Coil Design: Constructed of aluminum fins bonded to internally grooved aluminum tubing and are more corrosion resistant

. Versatile 4-Way Convertible Compact Design: Allow for upflow, downflow, horizontal left and horizontal right applications even in the smallest of spaces

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

. Field Installed Auxiliary Heater Kits: Provide exact heat for indoor comfort and include circuit breakers which meet UL and cUL requirements for service disconnect

. Less than 2% Cabinet Air Leakage at 1-inch H2O: When tested in accordance with ASHRAE Standard 193

. Designing for Sustainability with Low GWP: For 2025, the Environmental Protection Agency (EPA) has set a global warming potential (GWP) limit of 700 for refrigerant used in heating and cooling systems. This new requirement will result in a 78% lower GWP than previous-generation refrigerants - with only minimal changes to system installation. For us, this is another step toward our continued sustainability goal of reducing greenhouse gas emissions, while still delivering an exceptional level of energy efficient, dependable comfort

. PlusOne Refrigerant Detection System: An integrated one-box, 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
