Modine Heat Recovery Coils (HRCs) – High-Efficiency Solutions for Condensing Furnaces in South Texas
When it comes to high-efficiency furnaces (90%+), durability and performance aren’t optional—they’re essential. Modine heat recovery coils (HRCs) are specifically engineered for condensing furnace applications in both residential and commercial markets. Built with 29-4C super ferritic stainless steel tubes, headers, and turbulators, these coils are designed to withstand the corrosive combustion by-products that naturally occur inside high-efficiency systems.
Backed by decades of experience, Modine’s engineering team works directly with you to optimize coil design for your exact cost and performance requirements. With four different fin thicknesses and five fin configurations available, Modine heat recovery coils can be fine-tuned to balance efficiency, airflow, and durability for virtually any system.
Why Heat Recovery Coils Matter
In a high-efficiency condensing furnace, exhaust gases first pass through a primary heat exchanger before entering a secondary one. Inside this secondary exchanger, additional heat is extracted as water vapor condenses into liquid—releasing latent heat that drives furnace efficiency even higher. Because of this process, the secondary heat exchanger must be built to resist heat, moisture, and acid. That’s why Modine uses stainless steel construction—delivering long-lasting, reliable performance.
Key Benefits of Modine Heat Recovery Coils:
- Built with 29-4C stainless steel for superior corrosion resistance.
- Multiple fin thicknesses and designs for performance customization.
- Proven reliability in 90%+ condensing furnace applications.
- Supported by Modine’s experienced application engineers.
For HVAC contractors and facility managers across South Texas, Tillman & Associates supplies Modine heat recovery coils that keep high-efficiency furnaces running at peak performance—without premature failures or costly downtime.
