These pressure vessels are filled with activated carbon and are used to clean pollutants in sewage. Activated carbon is particularly suitable for absorbing organic substances. As an alternative, the vessels are also suitable for the treatment of turbidity filtration during beverage processing. The vessels are construed designed for a maximum operating pressure of 5 bar.

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.

Steam exhaust silencers (also: tension release silencers) are often placed behind safety equipment such as valves or flaps. When these open, a large amount of steam flows, with an overpressure, into the tension release expansion stage (perforated steel plate throttle) which has been fitted with a silencer. In the upper part of the silencer there are sound-absorbing fittings, which reduce the noise of the valve and the flow noise according to the sound requirements.

Cyclones are designed as centrifugal separators and, therefore, also used as filters. The construction is robust and contains no filter media (low-maintenance). The starting medium is blown in via the tangential media inlets. Solids and heavier components are guided downwards by gravity and passed through sluices or caught in dust collecting boxes.

Vessels and pipelines in the food and beverage industries must be constructed to withstand stringent cleaning and disinfecting. A maximum roughness (Ra) of 0,8 µm is often required in the component interior. Foil wrapped, cold-rolled sheet metal (2B) is used and the weld seams are tested for flaws and ground flush with the sheet metal surface in several steps.
