Carrier 48SS660004 Heat Exchanger

The Carrier 48SS660004 Heat Exchanger is a critical Factory Authorized Part designed for high-performance thermal transfer in specific Carrier, Bryant, and Payne gas heating and electric cooling rooftop units. Engineered with aluminized steel for superior corrosion resistance and longevity, this replacement heat exchanger features a 4-tube configuration that ensures efficient combustion airflow and heat dissipation. It is a direct-fit component for Carrier 48SS series units, ranging from 1.5 to 5 nominal tons, supporting both horizontal and downflow duct configurations. This OEM HVAC part is built to handle the rigorous duty cycles of commercial packaged rooftop units (RTU), ensuring the integrity of the heat exchange process and preventing combustion byproduct leakage into the supply air stream. For contractors, this assembly provides a precise drop-in replacement, maintaining the original system's AFUE ratings and operational safety without the need for field modifications.

• OEM Compatibility: Guaranteed fit for Carrier 48SS660004 specifications, eliminating alignment issues during furnace repair.
• Corrosion Resistance: Heavy-duty aluminized steel construction protects against condensate-induced oxidation and thermal stress cracking.
• Optimized Heat Transfer: The 4-tube Super-S design maximizes surface area contact to maintain heating efficiency.
• Diagnostic Reliability: Seamlessly integrates with the Integrated Gas Control (IGC) board and flame rollout switches for safe operation.

• Which rooftop units are compatible with this heat exchanger? This part is specifically engineered for Carrier 48SS series models and corresponding Bryant 580D or Payne equivalents. Always verify the model and serial number before installation.
• Does this include the insulation kit? As a technical assembly, the 48SS660004 typically requires an insulation kit (such as 48SS660002) for a complete HVAC maintenance overhaul.
• Why is a freight quote required for this item? Due to the structural dimensions of approximately 32.5" x 22.5" and the risk of tube deformation during transit, this item requires specialized truck internal handling.
