METZEN INDUSTRIES GMBH - When it really matters.

We offer a wide range of efficient, reliable water management systems for Wastewater management Rainwater management We design, manufacture, and install mechanical and electrical equipment for water management systems. Our clients include organisations, local authorities and industrial companies in Benelux and Germany. We develop comprehensive water management technology and systems, which make technically, economically and ecologically optimised solutions possible along the entire value chain.

Korzonek Klarwerkstechnik, METZEN’s sewage treatment branch, has been a competent and trusted sewage engineering partner to local authorities, wastewater companies and industrials for over 30 years. We design and manufacture custom spare parts for all scrapers and refurbish them to guarantee their long service life. Longitudinal scraper chassis Circular scraper chassis Drive wheel with direct drive for circular scrapers Rack-and-pinion drive chassis Rack-and-pinion rails Longitudinal scraper chassis with stabilising cross beam and rail drive Rack-and-pinion drive with rail impeller Bolt rail for rack-and-pinion drive Rail longitudinal scraper chassis with synchronously controlled drive Pivot bearings and slip ring systems We manufacture and assemble pivot bearings and slip ring systems with hose swivel joints or without hose access. Scraping blades for longitudinal and circular scrapers We manufacture and assemble single and multi-piece scraping blades.

We build entire plants and components for your recycling process line: separating – washing – conveying – processing METZEN provides you with machinery and complete plants for plastics recycling, e.g., for agricultural films, PET bottles, mixed municipal waste and much more. We build components for every stage of your process line: separating – washing – conveying – processing

We support you throughout your design process and consider all the necessary technical requirements for welding. We can also produce components and assemblies from scratch. METZEN supports you with everything from purchasing materials to welding, mechanics, required checks and authorisations, surface treatment and, finally, documentation. Our product range includes normal steel vessel construction, stainless steel vessel construction/stainless steel pressurised vessel construction and aluminium vessel construction.

As the NW 400 sight glasses required for the vessel were not standard, an exceptional 3.2 inspection needed to be carried out for them. FMS created a suitable testing fixture for this inspection and then successfully carried out a type examination together with the Technical Inspection Association (TÜV). Design/planning Preparation of pre-test documents for the TÜV Procurement of all materials Pressure and burst tests for the sight glasses Welding Mechanical engineering Surface treatment Fully assembly TÜV acceptance of the pressure and leak test (using SF6 gas) Documentation and acceptance

FMS manufactured diverse switch and drive casings for this switchgear system. Assignment: Optimise the welding seam design Increase the level of mechanisation in the welding process Simplify the mechanical finishing process by calculating the tolerance chain and through constructive redesign Management of the whole project including packaging optimisation at the assembly site

Busbar and circuit breaker vessel and containers in various designs Welding Full dimension check Mechanical engineering Pressure testing Leak testing with SF6 gas Documentation Acceptance

For example, pressure vessels in accordance with the category IV DGRL97/23 EG Design support according to technical welding requirements Procurement of all materials Welding Mechanical engineering Pressure/leak testing Non-destructive testing Surface treatment Documentation

For high voltage energy supply/distribution Welding (incl. welding on bolts) Pressure testing with SF6 gas Full dimension check (providing DXF file) X-ray inspection of welding seams where possible, inspection of all other seams with ultrasound Mechanical engineering

For example, casing made of nickel-chromium steel 1.4571 Procurement of materials Welding Mechanical engineering Surface treatment
