Trane 5TXCB006AS3HCA – 42-48,000 BTU 3.5–4.0 Ton Aluminum Cased Upflow / Downflow / Horizontal Evaporator Coil

Deliver reliable indoor cooling and heat pump performance with the Trane 5TXCB006AS3HCA, a premium aluminum evaporator coil engineered 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 designed to support efficient refrigerant control and dependable HVAC system operation.

3.5–4.0 Ton Cooling Capacity Platform
The 5TXCB006AS3HCA evaporator coil supports nominal cooling capacities ranging from approximately 3.5 to 4.0 tons when paired with compatible Trane split system air conditioners or heat pumps. The coil uses a three-row plate-fin configuration with 14 fins per inch and approximately 5.5 square feet of face area, supporting efficient heat transfer and balanced 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 corrosion resistance. This all-aluminum coil construction helps maintain long-term durability while supporting consistent refrigerant flow and reliable cooling performance in residential HVAC environments.

Factory-Installed Non-Bleed TXV Refrigerant Control
The 5TXCB006AS3HCA features a factory-installed non-bleed thermostatic expansion valve (TXV) designed to precisely regulate refrigerant flow during cooling and heat pump operation. This refrigerant metering device helps maintain stable evaporator temperatures, improve energy efficiency, and optimize HVAC system performance under varying load conditions.

Compatibility with R-454B Refrigerant Systems
The coil is designed for use with R-454B refrigerant systems and includes 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 split system performance.

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

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 configurations. This dual drain pan design helps ensure reliable condensate removal and protects HVAC 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 configuration simplifies routine maintenance and helps maintain long-term HVAC system efficiency.

Compact Cased Coil Cabinet Design
The 5TXCB006AS3HCA features an uncrated cabinet size of approximately 26.75 inches high, 17.5 inches wide, and 21.5 inches deep , allowing installation in residential mechanical spaces while maintaining proper airflow capacity for efficient system operation.

Engineered for Efficient Split System HVAC Performance
Ideal for residential cooling and heat pump systems, the Trane 5TXCB006AS3HCA evaporator coil combines durable aluminum construction, precise refrigerant control, and flexible installation capability in a compact cased coil platform designed to support dependable indoor comfort and long-term HVAC system performance.
