Plant construction

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.
