Overview
The New 48K Btu PEAQ Multi-Voltage Air Handler by Cooper&Hunter is a revolutionary HVAC solution designed to elevate home climate control. Utilizing the new R454B refrigerant, this slim indoor unit, with a width of 21.5", matches most gas furnaces, making it an ideal replacement for an existing system. The PEAQ unit is a single-zone, high-performance air handler offering both horizontal and vertical installation for maximum flexibility.
Its adaptive multi-voltage capability (115V & 208-230V) automatically identifies the required voltage without manual conversion, eliminating the hassle of rewiring. With a SEER2 rating of up to 17.5, the 48K PEAQ unit ensures exceptional energy efficiency. The innovative M-COIL design delivers less than 0.02 in. W.C. pressure drop, providing a mere 2% airflow difference between evaporators.
Features
- Adaptive multi-voltage capability (115V & 208-230V) with automatic voltage detection
- Slim 21.5" width matches most gas furnaces for easy replacement
- M-COIL design: less than 0.02 in. W.C. pressure drop, ~2% airflow difference between evaporators
- TU1 copper tubes for excellent electrical/thermal conductivity and corrosion/cold resistance
- Symmetric fan blower design for even airflow and higher efficiency heat exchange
- Refrigerant leak sensors and factory-installed drain pan heater to prevent ice accumulation
- Ultra-efficient discharge fan prevents frost on compressor coils
- Detachable delay fuse protects the indoor/outdoor wire set from overcurrent
- Optional auxiliary heater available separately (5kW, 10kW, 15kW, or 20kW)
What's Included
- Indoor Air Handler Unit CH-PQ48AHU
- Built-in Smart Kit with downloadable Cooper&Hunter app
- Remote Control
