About VoTech Filter
VoTech Filter GmbH is a second-generation, owner-managed manufacturer of filter cartridges and separation systems for natural gas and industrial gases based in Heinsberg. Founded in 1985, the company manufactures filter cartridges for use in filter and separator vessels in natural gas and industrial plants, including dry dust filter cartridges, coalescers, and complete filter and separator solutions for liquid and solid particle removal in downstream, midstream and upstream applications. As an original manufacturer, VoTech supplies apparatus builders and engineering companies and offers filter media for multiple temperature ranges. Design is carried out to customer specifications or as standardization according to national and company standards, supported by CAD engineering. In its own R&D laboratory "Æolus", standard products and new developments are tested for separation efficiency and differential pressure; fundamental research and quality inspections are carried out flexibly. The ISO-9001 certification (TÜV Rheinland, initial certification 2007) covers development, production and distribution of filters and separators for the petrochemical, power plant and biogas industries.
