Outdoor Unit Single-Zone Light Commercial Ductless Heat Pump Puron Advance R-454B 3 Ton 208/230 V 1-Phase 60 Hz

The Outdoor Unit Single-Zone Light Commercial Ductless Heat Pump Puron Advance R-454B 3 Ton 208/230 V 1-Phase 60 Hz (37MBRAQ36AA3) is a heavy-duty single-zone inverter outdoor condenser built for light commercial or demanding residential applications using Bryant’s Puron Advance™ (R-454B) refrigerant to deliver balanced cooling and heating performance with good seasonal efficiency when matched to an appropriately sized indoor air handler. It runs on 208/230 V single-phase, 60 Hz power and uses inverter modulation to deliver precise capacity control, quieter operation, and reliable comfort. For proper job fit, technicians must verify the selected indoor unit is sized for the 3 Ton outdoor capacity, confirm correct refrigerant line sizing and piping length, and ensure the electrical supply meets the unit’s MCA and MOCP requirements with appropriate disconnecting means. Accurate system matching reduces capacity mismatch issues and supports long-term reliability in commercial or high-load residential settings.
