Trane 5TXCB004AS3HCA – 36-42,000 BTU 3.0–3.5 Ton Aluminum Cased Upflow / Downflow / Horizontal Evaporator Coil

Deliver efficient cooling and heat pump performance with the Trane 5TXCB004AS3HCA, a premium aluminum evaporator coil designed for residential split system HVAC applications. As part of Trane’s 5TXC Series Comfort™ coil platform, this cased indoor coil features durable aluminum plate-fin construction, a factory-installed non-bleed thermostatic expansion valve (TXV), and flexible multi-position installation capability engineered to support efficient refrigerant control and dependable HVAC system operation.

3.0–3.5 Ton Cooling Capacity Platform
The 5TXCB004AS3HCA coil is designed to support nominal cooling capacities ranging from approximately 3.0 to 3.5 tons when paired with compatible Trane split system air conditioners or heat pumps. The coil features a three-row plate-fin configuration with 12 fins per inch and approximately 5.0 square feet of face area, supporting efficient heat transfer and consistent airflow performance for residential HVAC systems.

Aluminum Plate-Fin Coil Construction
The evaporator coil utilizes 3/8-inch seamless aluminum tubing mechanically bonded to aluminum plate fins to promote efficient heat transfer and long-term corrosion resistance. This all-aluminum construction helps improve durability while maintaining reliable refrigerant flow and cooling performance across residential HVAC installations.

Factory-Installed Non-Bleed TXV Refrigerant Control
The 5TXCB004AS3HCA includes a factory-installed non-bleed thermostatic expansion valve (TXV) designed to precisely regulate refrigerant flow during cooling and heat pump operation. This metering device helps maintain proper evaporator temperatures, improve energy efficiency, and optimize system performance under varying load conditions.

Compatibility with R-454B Refrigerant Systems
The coil is designed for use with R-454B refrigerant systems and features brazed refrigerant connections with a 7/8-inch gas line and 3/8-inch liquid line connection. This configuration supports compatibility with modern Trane outdoor units engineered for next-generation refrigerants and high-efficiency HVAC system performance.

Multi-Position Installation Flexibility
The 5TXC Series cabinet supports installation in upflow, downflow, or horizontal configurations, allowing the coil to be installed in a wide range of residential HVAC system layouts. This installation flexibility simplifies integration with compatible furnaces or air handlers depending on system design and mechanical space availability.

Integrated Drain Pan Design for Condensate Management
The coil assembly includes a vertical drain pan with primary and secondary drain connections for vertical installations as well as a horizontal drain pan with primary and secondary drain connections for horizontal applications. This dual drain configuration helps ensure reliable condensate removal and protects surrounding system components during cooling operation.

Service-Friendly Cabinet with Coil Access
The cabinet design includes removable front and interior access panels that allow technicians to easily access the evaporator coil entering air surface for inspection and cleaning. This service-friendly design simplifies routine maintenance and helps maintain long-term HVAC system efficiency.

Compact Cased Coil Cabinet Design
The 5TXCB004AS3HCA features an uncrated cabinet size of approximately 22.5 inches high, 17.5 inches wide, and 21.5 inches deep. The compact cased design allows installation in tighter residential mechanical spaces while maintaining proper airflow capacity for efficient system performance.

Engineered for Efficient Split System HVAC Performance
Ideal for residential cooling and heat pump applications, the Trane 5TXCB004AS3HCA evaporator coil combines durable aluminum coil construction, precise refrigerant control, and flexible installation capability in a compact cased coil platform engineered to support dependable indoor comfort and long-term HVAC system performance.
