Heating & Cooling Coils

Commercial HVAC Coils - Chilled Water Coils


Colmac chilled water coils are suitable for use in a wide variety of HVAC air cooling and dehumidifying applications. Standard and custom designs are available for new and retrofit installations. Colmac CoilPro web-based software is ideally suited for quickly and accurately selecting chilled water coils for air handlers and built up systems. This proprietary program allows the user to vary coil circuiting (feeds and passes), fin spacing, and materials of construction to reach the optimum coil selection for any set of operating conditions in ways just not possible with other manufacturers’ software. Copper, cupro-nickel, aluminum, and stainless steel tubes and fins are available for chilled water coils to match the performance requirements and level of corrosion resistance needed for your application. Custom replacement coils are a Colmac specialty. Our applications engineers will assist you in matching existing coil construction and dimensions to create the “perfect fit” for your replacement coil project.
