The chamber for the special machine construction consists of 5-10mm thick walls. The metal profiles and ribbings are circumferentially welded for stabilization against negative pressure. The liquid-tight vacuum chamber is used for automated cleaning operations.

Throttle valves are used for air volume control in order, for example, to regulate various extraction points or to block off individual ducts. Welded throttle valves (shaft, flap, bearing) have to be adjusted to the mechanical requirements of the plant – pressure, speed, temperature, medium.

Hot exhaust gas from parallel oven shafts is extracted through 6-10 flexible and valve controlled branches and discharged through the main pipe. The manifold has a diameter of approx. 1 m, is continuous welded and can be assembled as one solid piece.

Ventilation systems for combustion air are used in furnace technologies for aluminium production. One special feature is that the equipment is mounted on steel springs for an elastic bearing and can be entirely moved with a factory crane. The systems are manufactured and completely assembled in our factory and then delivered after a performance test.

Noise protection enclosures are needed for gas and steam turbines due to their extreme noise levels (comparable to airplane turbines). The noise protection enclosures are modularly constructed as an assembly kit, delivered with a hot-dip galvanised steel base and assembled on site. Several parts of the enclosure are accessible for inspection and maintenance purposes.

The supply air unit delivers fresh air to the power plant, e.g. in turbine or boiler houses. External air is sucked in through a weather protection grill and a multi-leaf damper and then led back into the room through a suction silencer. If needed, a heater can be integrated in order to warm the intake air.
