Restructuring of a production hall - a clever combination for more energy savings

The halls of the aluminium plant Unna are used for different work processes, e. g. a foundry, a press plant, a shipping hall and modern testing facilities. Next to new buildings there are also halls older than a hundred years.

The halls were originally heated with a warm air system. Since 2004 the system has been successively renewed. Due to the different uses and construction of the halls, the requirements for the new heating system were manifold.

In close cooperation with the customer ALUnna we found the perfect solution:

Until now 78 high intensity heaters as well as 30 tube heaters are installed, most of which are equipped with the condensing gas heat exchange system TRIGOMAX^®. 24,820 m² of the hall area have been modernized with GoGaS devices. Further areas are already planned.

Through the full restructuring of the aluminium plant energy savings of over 50 % have been achieved. This value is verifiable at any time by the company’s certified energy management.
