Product Description

The Trane 5TMM5B0B30M21S is a 2.5-ton wall-mount air handler designed for residential split-system cooling and heat pump applications. Part of the RunTru by Trane product line, it operates on 208-240 volts, single phase, 60 Hz and is rated for 30,000 BTU/h nominal capacity. The unit uses refrigerant R-454B and features an all-aluminum plate fin slab coil with a factory-installed TXV metering device. A multi-speed direct-drive blower motor delivers airflow in the range of approximately 1,077 to 1,362 CFM. System control operates at 24 volts. Licensed HVAC technicians install and service this unit.

The 5TMM5B0B30M21S is configured for upflow-only, wall-mount installation and is suited for residential applications where floor space is limited. Typical install locations include closets, utility rooms, and alcoves, as well as stud-wall or over-water-heater mount configurations. The unit supports single-stage cooling operation and is designed to pair with a compatible outdoor condensing unit or heat pump. Optional electric heater kits in 5, 7.5, and 10 kW ratings are available as accessories for this series. In many split-system configurations this air handler may be sized one nominal ton above the outdoor unit to optimize system efficiency.
