ZELTWANGER Fin Mill

THE FUTURE OF HEAT EXCHANGER PRODUCTION

Highly efficient heat exchanger fins are the core components of high-performance heat exchangers. Intelligent and pre-designed systems based on standardized processes and architectures are key to producing a high-performance fin mill.

OUR SOLUTION FOR TECHNICALLY SUPERIOR
HEAT EXCHANGER PRODUCTION

Requirements for complex fin geometries and extremely high fin densities are met thanks to the high-precision fin production system. Ranging from corrugated fins right the way up to oil cooler fins, a wide variety of fin types can be produced. The production process achieves a fin height accuracy of ± 0.01 mm at speeds of up to 6.5 m/s. Performance can be increased by using the double-track system.

A further advantage of the machine is its compact size, as the control cabinet is integrated in the machine’s base frame. Overall, the footprint of our fin mill is 50% smaller than other machines available on the market.
