Müller GmbH & Co. KG Tank & Plant Construction

What Müller GmbH & Co. KG Tank & Plant Construction does

Müller GmbH & Co. KG Tank & Plant Construction is a privately held, family-owned German Mittelstand manufacturer founded in 1950 by Walter Müller and currently led by Managing Director Oliver Müller from its headquarters in Gernsbach, Baden-Württemberg. The company specializes in the design, fabrication, and on-site assembly of industrial containers, tanks, pressure vessels, silos, gas scrubbers, and complete plant systems — including complete tank farms with associated pipelines, gangways, and platforms. Production runs on a 1,400 m² indoor facility for vessels up to 4.3 m in diameter and 26 m in length, and on a proprietary on-site Coilbuilding© process using a dedicated mobile machine that assembles containers up to 30 m in diameter, 150 tonnes in weight, and 6,000 m³ in capacity directly at customer premises, with oversized units delivered via an external support point on the Rhine.

The underlying technology stack centers on the Coilbuilding© coilbuilding and tank-building process, modern welding methods including plasma keyhole and TIG oscillation welding that reduce a typical 1,000 m³ tank's pure assembly time to roughly four weeks, and state-of-the-art 3D/2D CAD software for plant layout and design. Structural and FEM analyses are conducted with an external engineering firm and verified in collaboration with TÜV. The company is certified to AD 2000-Merkblatt HP0 since 1988, Pressure Equipment Directive 97/23/EC, DIN EN ISO 3834-3, EN ISO 14731 (with an in-house IWE welding engineer), WHG, SCC* 1-star, and EN 287-1 welder qualifications, and works with inspection bodies including TÜV, Dekra, Bureau Veritas, and Lloyd's Register.

Revenue is generated through project-based, quote-driven B2B contracts for custom engineered vessels and plant systems — pricing is not publicly disclosed and is determined per project by specifications, materials (stainless steel grades 304/304L/316/316L/316Ti/321 and duplex grades), dimensions, complexity, and whether production is indoor or on-site. Go-to-market is enterprise field sales with dedicated project managers (e.g., Construction & Project Manager Heinrich Fischer) accompanying customers from planning and CAD engineering through to commissioning. Customers are industrial buyers across chemical/petrochemical, wastewater treatment, paper/pulp, energy (including biofuels, urea, heat storage), and oil and gas; no named end-customer logos are publicly referenced. The firm employs roughly 25 staff, is self-funded with no disclosed institutional investors, and markets itself globally through its corporate website with downloadable brochures in German and English and a video gallery.

Core offering

Müller GmbH & Co. KG designs, engineers, fabricates, and commissions custom industrial tanks, pressure vessels, stainless steel containers, reactors, and complete plant systems for chemical, wastewater, paper, energy, and oil and gas customers. Manufacturing is delivered through two production modes: indoor factory production at a 1,400 m² facility in Gernsbach and on-site production using the proprietary Coilbuilding© machine for vessels up to 30 m diameter and 150 tonnes weight.

Product overview

Müller GmbH & Co. KG is an industrial tank and container manufacturer offering a comprehensive portfolio of steel containers, tanks, pressure vessels, and plant systems. The product portfolio includes bulk containers, stainless steel containers, storage tanks, pressure vessels, gas scrubbers, mixing containers, silos, and complete plant systems with associated wastewater treatment vessels (anaerobic reactors, MBBR, biobed reactors, cascade reactors). Services are delivered through two manufacturing approaches: Indoor Production (Tank Building) in the Gernsbach factory for components up to 4.3m diameter and 26m length, and On-Site Production using the proprietary Coilbuilding© technology for large vessels up to 30m diameter and 6,000 m³ capacity. Supporting services include Planning & Engineering (3D CAD design, structural/FEM analysis), commissioning, and manufacturing/construction monitoring. Materials processed include stainless steel (304, 304L, 316, 316L, 316Ti, 321) and duplex steel grades.
