ABOUT Colmac Coil Manufacturing Inc.

Colmac Coil is an expert in the heat transfer and refrigeration industries, serving a number of vital markets that include aeronautics, beverage, communications, dairy, electronics, energy reclamation, food processing, gas compression, health care, hospitality, industrial process, packaging, pharmaceutical, petrochemical, power generation, pulp and paper, waste and water treatment. The company specialises in applications that require quality levels beyond that which is available with commercial grade equipment.

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. The facility is set-up for flexible coil assembly rather than being restricted to standard modular units produced on high speed production lines. Customers have the option of ordering customised equipment to meet their specific requirements.

In 2009, Colmac Coil purchased the Aircoil™ evaporator line from Baltimore Aircoil Company. The company also purchased the former BAC manufacturing facility in Paxton, Illinois, which now manufactures its complete product line.


New Cascade Heat Exchanger Technology

Colmac Coil Manufacturing is pleased to announce the introduction of its new Shell and Helix heat exchanger intended for use in Ammonia/CO2 cascade refrigeration systems. The new heat exchanger design offers the following advantages and benefits:

All stainless steel construction for corrosion resistance and long life. Compact - large heat transfer surface in small volume. Cost effective compared to other heat exchangers in the market. High tubeside (CO2) pressure capability - as high as 1,700 psig (119 bar). Multiple helix design permits expansion and contraction of tubes during large changes in temperature and pressure with very low resulting strain and stress reducing the risk of failure and leaks. Nesting of the multiple helically formed tubes in both radial and axial directions results in equal spacing of the tubing and uniform flow distribution on the shellside. Multiple shell side connections allow reversing the flow of the ammonia and CO2 - permits reverse cycle hot gas defrosting. US and International Patents Pending.
