Carrier 48TJ660010 Heat Exchanger

The Carrier 48TJ660010 Heat Exchanger is the factory-authorized replacement for the discontinued 48TJ660002, specifically engineered for high-performance rooftop unit (RTU) applications. As a critical component in your client's commercial HVAC system, this 5-tube aluminum heat exchanger features an integrated exhaust regulator to ensure precise draft control and safe combustion-gas expulsion. Designed for durability in demanding environments, it maintains optimal heat transfer efficiency while preventing the common mechanical failures associated with older baffle designs. For a complete and professional installation, technicians should verify the condition of existing flame retainers (50HJ500451) and inducer support assemblies (50DK406230), as these are often required to complete the assembly. Utilizing genuine Carrier OEM parts like the 48TJ660010 ensures exact physical dimensions (approximately 33" x 22.5" x 13") and mounting hole alignment, significantly reducing labor hours during a heat exchanger replacement and restoring the unit’s energy efficiency to original specifications.

• Direct OEM Replacement: Fully replaces the obsolete 48TJ660002, providing an exact fit for 48TJ and 48HJ series commercial rooftop units.
• Integrated Exhaust Regulator: Simplifies the swap-out process by including the regulator pre-installed, ensuring proper venting and combustion safety.
• Heavy-Duty Construction: Built with high-grade aluminum for superior thermal conductivity and resistance to thermal stress and corrosion.
• Optimized Airflow: Engineered for 3-15 ton package units to provide reliable heating performance while minimizing airside pressure drop.

Is the Carrier 48TJ660010 a direct drop-in for the 48TJ660002?
Yes, the 48TJ660010 is the specific update for the 48TJ660002. It includes the necessary exhaust regulator and fits the same footprint used in hundreds of Carrier and Bryant package units.

What additional parts are needed for this heat exchanger installation?
Standard field practice recommends replacing the flame retainer (part number 50HJ500451) and inspecting the inducer support component (50DK406230) to ensure the combustion assembly is fully sealed and operational.

Why is the exhaust regulator included on this model?
The integrated regulator on the Carrier 48TJ660010 manages the vent flow and draft. This design improvement ensures consistent heat exchange and prevents diagnostic faults related to improper combustion venting.
