DuoFin™

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.

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.

Additional information

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. Having only two fins means you’ll never have to clean debris from between the fins.

Also available with shorter fins, DuoFin Lite is designed for areas requiring less heat.

New and improved DuoFin features a ridged surface, increasing heat performance by up to 10.5%.

How it Works

Aluminum Fin Pipes, like StarFin™, DuoFin™, and SunFin™, efficiently transfer heat by circulating warm water through the pipe system, with the aluminum fins providing an extended surface area to radiate heat into the greenhouse environment. This design ensures even and consistent heat distribution, optimizing the growing climate.

Why Aluminum Fin Pipes?

Our Aluminum Fin Pipes, like StarFin™, DuoFin™, and SunFin™, offer efficient, shadow-free heating with versatile applications for under-bench, in-crop, perimeter, and gutter systems.

Enhanced Heat Radiation

DuoFin’s two tapered fins provide superior surface area, delivering efficient and consistent heat for optimal plant growth

Perfect for Under-Bench or In-Crop Applications

Designed for precision, DuoFin™ is ideal for under-bench or in-crop heating applications, targeting the root zone for healthier crops and shorter growth cycles

Energy and Installation Efficiency

Lightweight and easy to install, DuoFin™ reduces energy costs while offering a hassle-free setup with no welding required
