Plant calls for the widest variety of window solutions. For sewage plants, purification plants, processing plants, filter systems, metal printing plants and other plants we manufacture pressure-tight gauge glasses, inspection windows and doors, optionally available for opening complete with a wiper and a lid. The constructions are either custom-built, or are products based on our module system and can be adjusted to suit different requirements. We produce the safety components in high-grade steel, light metal or heavy metal; they are pressure-tight up to 0.25 bar. The seals are made from high-quality neoprene, viton or silicone. All products comply with the highest safety requirements, are highly durable and maintenance-free.
Krones – pressure-tight entry doors made of glass
For the world market leader Krones we developed and produced glass entry doors for a new kind of bottle-cleaning plant. The aseptic cleaning process calls for reliable pressure-tight seals and for an alarm switch if the seal is broken. The Fehrmann team designed and produced frameless doors in a slim construction.
Aqseptence – windows and gauge glasses in filtration plants
Windows and gauge glasses in filtration and separation plants for water treatment fulfil a wide variety of requirements: they allow inspection, serve as an escape route and allow material to be lowered into the plant. At the same time, they need to be reliable and to supply a permanent seal. Fehrmann's tried-and-tested gauge glass constructions are maintenance-free and offer the maximum reliability and durability.
Vienna: main sewage plant / GIS Aqua – pressure-tight gauge glasses in red brass
For many sewage plants, e.g. for the City of Vienna's large-scale project to use renewable energy "e_os 2020", we produce pressure-tight gauge glasses for digestion towers from Fehrmann's module system. This allows a customised configuration for any purpose. The glasses are available in red brass, bronze, high-grade steel or aluminium – round or square, openable or not, with a windscreen wiper or a lid.
