Echelon BUH 018-060 (3-phase only)

Echelon BUH 018-060 (3-phase only)

BUH 018 to 060 (available in 3-phase only)

These models are available only in 3-phase voltages.

Coleman Series single-package heat pumps are designed for outdoor installation that saves indoor living space. Nominal airflow of 600 to 2,000 CFM is provided by 3-speed, direct-drive, high-static motors. To make installation and maintenance easier, they offer field convertible side or bottom airflow, removable base rails, and bottom electrical connections. All models have the same footprint, so curbs can be placed and then the proper tonnage unit can be installed after the internal load has been determined. The compact dimensions allow any model to fit between the wheel wells of a full-size pickup truck for transport. Coleman units are also offered in three-phase configurations with 208/230, 460, and 575 voltages.
