Details

Colmac Coil is a world leader in the design and manufacturing of heat exchanger coils that are used in cooking, chilling, and freezing applications. Our unique offering of tube and fin patterns coupled with our wide range of tube and fin materials allows us to meet the needs of virtually any food processing application. We work closely with original equipment manufacturers (OEM), and installing contractors in the food processing industry to meet the most stringent requirements. Corrosion resistant construction for coils subjected to harsh cleaners such as sodium hypochlorite and/or potassium hydroxide are available. Colmac Coil anti-microbial coil construction actively kills pathogens such as E-coli, Listeria monocytogenes, and Salmonella, which come in contact with the fins. Other Colmac Coil innovations for the food processing industry include 3-A Sanitary Design hygienic evaporator coil designs for the dairy industry which have been inspected by the USDA and approved for use in the cheese processing industry. We can custom design your chilling or freezing coil using any working fluid in a variety of configurations to best suit your needs. Coils can be arranged for Gravity Flooded, Pumped (Liquid Overfeed), Direct Expansion (DX), or Brine operation.
