New Working Fluids for Colmac Coil Heat Pipes


COLVILLE, Wash. - Colmac Coil Manufacturing, Inc. announces that its online coil selection software, CoilPro, is now available with new working fluids for its full range of heat pipes.

These fluids expand the range of operating temperatures for heat pipes from -30 degrees to 200 degrees Celsius. This higher temperature range allows for heat recovery from higher working temperature airstreams.

"Previous heat pipe selections revolved around heat recovery from occupied building exhaust. These new working fluid heat pipe options revolve around higher temperature heat recovery from industrial ovens and drying processes," said Jeremy Olberding, Colmac Coil Sales Manager.

CoilPro software is available to the company’s sales representatives and original equipment manufacturing customers. CoilPro provides accurate selection and rating of coils and heat pipes, with the broadest range of materials of construction and working fluids in the industry.

CoilPro is capable of selecting and rating heat pipes with 5/8", 7/8", or 1" tubes in either copper or aluminum. Both flat plate and spiral fins are available. Accurate calculation of custom heat pipe designs are possible with:

  • Imbalanced exhaust and supply airflows
  • Varying fin spacing for exhaust and supply
  • Varying fin materials for exhaust and supply
  • Either waffle (configured) or flat plate fins
  • Heat Recovery or Wrap-Around heat pipe configurations


The software also allows the user to quickly obtain a price and dimensional specification drawing for the heat pipe selected. The program is browser driven and runs online. Updates are automatic and do not require that the user waste time downloading and reinstalling the program.

Qualified users can easily save and retrieve projects at the quotation stage, then later launch orders directly to Colmac MIS (Management Information System), reducing order processing time.

"This exciting new development with our online CoilPro software will dramatically increase our productivity and allow us to better serve our customers," said Olberding.

The full range of heat pipes is available at both Colmac Coil manufacturing plant locations in Colville, Washington and Paxton, Illinois.
