High-efficiency cooling unit (HEC)

Higher rolling speeds and higher productivity

Rolling oil is essential for aluminum cold rolling. Unfortunately, its temperature sensitivity limits the rolling speed. Our new high-efficiency cooling unit (HEC) pushes the boundaries and increases productivity by up to 20 percent.

We install our innovative high-efficiency cooling unit (HEC) in the interstand area of your TCM. Crucial here is the counterflow of rolling oil in a strip channel. This facilitates convection cooling.

The higher cooling efficiency boosts rolling speeds and increases productivity by up to 20 percent.

The two-stand TCM of Chinalco Southwest in China was the first aluminum cold rolling mill we equipped with HEC. The mill started operation in 2009.
