Colmac Aircoil™ Evaporators are available in five different styles, each suitable for a variety of applications. Each style was designed and built with the same guiding principle in mind: to bring premier components and materials together with modern manufacturing techniques to satisfy customer requirements more completely and cost-effectively than ever before. Coils are designed and manufactured according to the stringent requirements of ASME B31.5 (2001), which now addresses heat transfer component design. All coils are pressure tested to 350 psig with air under water.

Aircoil™ Evaporators are constructed with 0.875" diameter stainless steel, aluminum, or galvanized steel tubes, staggered in the direction of airflow to ensure maximum air turbulence and coil heat transfer efficiency. Die-formed, flat pattern fins are a continuous design with a clean full collar to optimize performance, resistance to airflow, and cleanability. The flat pattern also reduces resistance to airflow, providing performance comparable to corrugated fins at a given horsepower. Each coil is individually circuited for specific applications in recirculated, flooded, direct expansion, or control pressure receiver refrigeration systems along with water, glycols, or brines.
