InfraCooler, Gestamp Hardtech

Perfect cooling of sheet metal

After three years of development and tests we can now present our most recent invention, the InfraCooler. Infrasound creates an intensive turbulence with particle velocities over 70 m/s. This increases the heat transfer rate between the cooling object and the surrounding cooling water dramatically. With this technology, we have helped Gestamp Hartech reduce their cycletime with more than 10% while also improve the quality of the end product.

How it works

1. Infrasound makes nitrogen gas move in the cooling box with a high speed and turbulent flow

2. Heat is transferred from the blank to the gas

3. Heat is transferred from the gas to the water cooled fins
