Water coils serve as the backbone of modern hydronic HVAC systems and industrial process cooling. These coils facilitate the precise transfer of energy between a liquid medium (typically water or a glycol-water mixture) and the airstream. Alpha Coil specializes in “Exact-Fit” replacements, ensuring that our custom designs match the performance curves and physical footprints of any legacy OEM system.

• Chilled Water Coils: Designed for high-performance cooling and dehumidification, our chilled water coils are optimized to handle the latent heat loads of humid environments. We utilize staggered tube patterns to increase air turbulence and surface contact, ensuring maximum thermal exchange. Our engineering team can adjust row depths and fin density to meet the specific “leaving air temperature” required for your facility.
• Hot Water Coils: Engineered for heating applications in central air systems and branch ductwork, our hot water coils are built to withstand the rigors of thermal cycling. We utilize heavy-duty headers and reinforced tube-to-header joints to accommodate the expansion and contraction that occurs as water temperatures rise, ensuring a leak-free lifecycle and consistent heating performance.
• Booster Coils (Reheat Coils): These high-response coils are designed for localized temperature management, typically installed in VAV boxes or terminal units. By providing “reheat” capability, they allow for independent zone control without affecting the main AHU settings. Our booster coils feature compact casing designs and optimized circuiting to provide rapid response times for modern office and healthcare layouts.
