New copper tube bending machine in the Roller machine park

The continuing high demand for high-quality heat exchangers and air coolers has prompted Walter Roller GmbH to invest further in the efficiency of its production capacity.
 
In copper-aluminum heat exchangers, horizontally running copper core tubes are usually installed. For production/cost reasons and for fewer welding joints in the sense of hermetization, long U-shaped 180° bends, so-called hairpins, are used for this purpose. Above a certain length, the production of the U-bends is only possible with larger, significantly longer machines.
