Rheem-Ruud AS-59066-89 Heat Exchanger

The Rheem-Ruud AS-59066-89 Stainless Steel Heat Exchanger Assembly is a precision-engineered OEM furnace replacement part designed for high-efficiency thermal transfer in residential and commercial units. As a veteran-grade S.S. Heat Exchanger Assembly, this component features a high-grade stainless steel construction that provides superior resistance to thermal fatigue and corrosive condensate, common issues in high-cycle environments. This assembly is a direct replacement for discontinued or failing Rheem heat exchanger series and is compatible with a wide array of models, including the UKKA, RKNL, and RKPL series. This HVAC secondary heat exchanger optimizes surface area contact to ensure maximum BTU recovery and consistent discharge air temperatures. For technicians, the integrated center panel and pre-aligned mounting points streamline the teardown and reassembly process, reducing labor hours and ensuring a leak-free seal within the vestibule. Professionals should verify the serial number for exact fitment before initiating a hot-zone teardown.

• Corrosion Resistance: Engineered with premium stainless steel to withstand acidic combustion byproducts and extend the life of the heat exchanger assembly.
• Optimized Efficiency: Maximizes heat transfer across the primary and secondary stages, maintaining the AFUE rating of the original equipment.
• OEM Precision Fit: Designed as a direct drop-in for Rheem and Ruud units, ensuring proper airflow dynamics and pressure switch alignment.
• Durable Construction: Heavy-gauge materials resist warping and cracked heat exchanger failures under high thermal stress.

Which furnace models are compatible with the AS-59066-89?
