Trane 5MXCD008AC6HCA Multi-position Cased Evaporator Coil 3 to 3.5 Ton R-454B 24.5 Inch Cabinet

Product Description

The Trane 5MXCD008AC6HCA is a single-stage, multi-position cased evaporator coil designed for use with R-454B refrigerant in residential split-system cooling and heat pump applications. Part of the Trane 5MXC-Series, this aluminum coil fits a 24.5-inch wide cabinet and covers a 3 to 3.5 ton capacity range, providing 48,000 BTU/h of cooling. It features a factory-installed piston metering device for refrigerant flow control and threaded female NPT connections on the liquid line. Licensed HVAC technicians install this coil as the indoor air-side component of a split system, paired with a compatible outdoor condensing unit or heat pump.

This coil is rated for upflow, downflow, and horizontal installation, making it adaptable to a wide range of residential duct configurations. The aluminum coil construction suits residential forced-air systems where a 24.5-inch cabinet width is required. It is part of the Trane 5MXC-Series lineup of R-454B-compatible cased coils, which spans 1.5 to 5 ton capacities. Typical installation scenarios include new construction and equipment replacement projects in single-family residential settings where R-454B refrigerant systems are specified.

Key Features

• Multi-position design supports upflow, downflow, and horizontal orientations in a single unit
• R-454B refrigerant compatible, meeting current low-GWP refrigerant requirements
• Factory-installed piston metering device for refrigerant flow regulation
• Aluminum coil construction throughout for corrosion resistance and heat transfer efficiency
• Threaded female NPT liquid line connections for field installation
• 24.5-inch cabinet width with a 6.1 square foot face area for adequate airflow capacity

Compatibility

The 5MXCD008AC6HCA is part of the Trane 5MXC-Series of aluminum single-stage cased coils designed for R-454B split-system heat pump and cooling applications. The American Standard equivalent part number is A5MXCD008AC6HCA. Confirm outdoor unit refrigerant compatibility and tonnage matching before installation.

Installation Notes

This coil must be installed by a licensed HVAC technician certified to handle R-454B refrigerant under applicable EPA Section 608 regulations. Shut down and lock out the entire system, including the outdoor condensing unit and air handler, before beginning any coil work. Verify that the air handler cabinet and duct connections are sized and sealed correctly for the chosen orientation prior to startup. Do not pressurize or charge the system until all connections are confirmed leak-free and the system has been properly evacuated.
