Solution

Older ventilation unit without heat recovery was replaced with a new cross-exchanger ventilation unit with 82% wet efficiency and high-efficiency EC motors and control of two different heating zones. Replacement means a significant optimisation of energy consumption for heating the production areas. The system is adjusted according to signals from the production machines and can be optimised to ensure a balance between intake and exhaust.

The piping system was reused as far as possible including fresh air intakes, supply ducts and parts of the exhaust ducts. Furthermore, new returns were established and the piping system optimised for the new system.

Older air intake hoods were replaced with modern air intake bags, which ensure a steady supply of fresh air to the production area, while at the same time ensuring an adequate supply of oxygen to the production processes.
