What Colmac Coil does

Colmac Coil Manufacturing, Inc. is a privately held, family-owned industrial manufacturer founded in 1971 in Colville, Washington, specializing in custom-engineered heat transfer equipment for commercial and industrial markets. The company's core technology platforms span plate-fin heating and cooling coils, dry and adiabatic fluid coolers, industrial refrigeration evaporators (the A+ Series family with multiple configuration variants such as A+S, A+L, A+M, A+P), and the proprietary ADX Low Charge Ammonia direct expansion refrigeration system, which is protected by six US patents and an Australian patent. Product portfolios also include CO2 industrial refrigeration solutions rated to 1740 PSIG with UL-207 certification, EC fan motors, and the HygenAir A+H hygienic air handler for food processing facilities requiring USDA compliance.

The company's business model is engineer-to-order, quote-based B2B industrial sales: customers work with Colmac's network of direct field-sales representatives and sales offices across the United States, Canada, and Latin America to specify custom equipment, with selection performed in the proprietary A+Pro and HygenAir parametric software tools. Revenue streams comprise one-time equipment sales for industrial heat exchangers and refrigeration products plus a subscription/recurring element for the A+Pro web-based selection platform. Certifications across ASME (Section VIII, U Stamp, B31.5), UL-207, CRN, CSA, CE, and PED on selected products serve as critical qualification assets for industrial, European, and Canadian buyers.

Customers served include major cold storage operators (Preferred Freezer Service, US Cold Storage, Joliet Cold Storage, Bidvest in Australia), automated ASRS facilities (NewCold, TI Cold CORE X Complete, both CEBA Built By The Best 2023 winners), food processors (Shepherd's Processed Egg, Alaska fish processing, national food processors), and government/defense accounts (NASA JPL Deep Space Network). Manufacturing is split between Colville, Washington (the original 1971 headquarters) and Paxton, Illinois (Midwest Production Factory expanded in 2024 with a Shuttlelift mobile gantry crane supporting 50,000-pound loads). The company operates with 51-100 employees under CEO/Owner Scott McMillan (third-generation family ownership) and President Joe Fazzari, P.E., and is actively exhibiting at IIAR National Conference and other trade events as of 2024.
