DuoFin™

Provides incredibly even heating across the width of your greenhouse growing areas.

BioTherm DuoFin™ for supreme heating evenness.

DuoFin provides incredibly even heating across the width of your greenhouse growing areas. Its unique tapered fin design delivers a combination of convective and radiant heating quietly and efficiently. Having only two fins means that more loops are needed to meet your heat load than with its sister product, StarFin—but it also means you’ll never have to clean debris from the fins. Also, the large inside diameter means less pumping energy is required to provide greater evenness than any competitive system. BioTherm DuoFin™ is our lowest heat output finned pipe commonly used for under bench, perimeter, and in crop heating. Its unique tapered vertical fin delivers a combination of convective and radiant heating quietly and efficiently. Also available with shorter fins, DuoFin Lite is designed for areas requiring less heat.
