"The Heat Transfer Experts"

Our History

Colmac Coil is a privately held, third generation, family-owned company founded in 1971 that has grown to be one of the world's leading manufacturers in the new and replacement coil markets. Colmac Coil's 225,000 sq. ft. manufacturing facility is located in Colville, Washington. Our facility is set up for flexible coil assembly. Rather than being restricted to standard modular units produced on high speed production lines, our customers have the option of ordering equipment customized to meet their specific requirements. 

Colmac Coil began as a spin-off of Colmac Industries, Inc., one of the world's leading garment finishing manufacturers. Colmac Industries was experiencing difficulty securing durable, quality coils with timely delivery, therefore the owners made the decision to found a separate company to manufacture the coils. 

In 2009, Colmac Coil purchased a manufacturing facility in Paxton, Illinois, which now manufactures our complete product line. The Pacific Northwest location provides close proximity to west coast ports for shipping to Asian and Middle Eastern markets. Our Midwest factory in Illinois has proven to be ideal for serving customers in the eastern U.S. and Canada. 

In 2012, Colmac Coil opened a Regional Sales Office located in Guadalajara, Mexico. With this addition, Colmac Coil accomplishes a strategic goal of having a strong local presence in the Latin American markets and is better able to serve customers throughout Latin America with faster response times for quotations and expert assistance with project logistics.
