Klaus

What Klaus does

Klaus GmbH & Co. KG is a German industrial manufacturer and service provider headquartered in Kißlegg, Germany, founded in 2003 by Marcel Klaus. The company operates three integrated business lines under one roof: (1) industrial suction systems including suction trailers with road approval, suction wagons with chassis or casters, stationary suction plants, and industrial vacuum cleaners marketed under the continued FIEDERLE brand acquired from Fiederle GmbH Umwelttechnik in November 2015; (2) custom metal construction services including stamping, turning, welding, sawing, drilling, milling, cutting, and bending of steel, stainless steel, and aluminum parts with surface finishing such as hot-dip galvanizing and painting; and (3) professional biogas fermenter cleaning services using specialized equipment (250 m³/hour feed pumps, compact loaders, excavators, explosion-protected fans) plus biogas plant components such as conveyor screws, dosing technology, conveying technology, digestate processing, insertion technology, and stirring technology. Core technical differentiation rests on a Druck-Vakuum-Kompressor design where the pump aggregate never contacts the medium, reducing sensitivity to foreign bodies and maintenance requirements.

The company serves industrial cleaning companies, biogas plant operators, municipalities and public services, recycling and disposal companies, and manufacturing plants across Germany. Notable customer relationships include Biogastechnik Süd, for which Klaus is a main supplier of biogas plant components. Klaus sells primarily through direct sales and personal consultation with no e-commerce channel, no publicly disclosed pricing, and a sales-led go-to-market that encourages phone or appointment-based engagement. Revenue is generated through one-time equipment sales, custom metal fabrication orders, usage-based rental of three suction trailers (200L, 1000L, 1500L tank capacities), professional fermenter cleaning services, and repair and maintenance services. The company holds DIN EN 1090-1 and DIN EN ISO 3834-3 certifications since 2014 for structural steelwork and welding quality, employs approximately 20 people, and is privately held with no external investors or parent entity.

Core offering

Klaus GmbH & Co. KG manufactures and sells industrial suction equipment — including trailer-mounted, mobile wagon, and stationary suction systems — under the Fiederle product line, for extracting oils, emulsions, coolants, wastewater, and high-solid-content liquids. The company additionally provides custom metal fabrication services (stamping, turning, welding, cutting, bending) and specialized biogas fermenter cleaning services that restore plant output by removing deposits.

Product overview

Klaus GmbH & Co. KG is a metalworking company specializing in industrial suction systems, metal construction, and biogas plant services. The product portfolio centers on FIEDERLE-branded suction equipment with three main product lines: (1) Sauganhänger/Saugwagen (trailer and wagon-mounted suction units with road approval, chassis-mount, or caster configurations), (2) Sauganlagen stationär (stationary suction systems in electric, pneumatic, and gasoline variants), and (3) Ölversorgungswagen (oil supply wagons). The company also produces specialized Förderschnecken (conveyor screws) for biogas plants and provides metal construction services including metalworking, custom fabrication, component construction, and safety railings. Additional service offerings include Fermenterreinigung (biogas fermenter cleaning) and repair/maintenance services. The company acquired the FIEDERLE GmbH Umwelttechnik product line in 2015, which is now fully integrated under Klaus.

• Feluwa Pumpen: German manufacturer of industrial pumps including peristaltic and hose pumps for abrasive and viscous media. Comparable to Klaus on the industrial fluid handling/pumping side, particularly where slurries with high solid content must be moved.
• WEDA Waldemar Förster: German manufacturer of suction vehicles and tankers for industrial and municipal cleaning applications. Closely comparable to Klaus's Fiederle suction trailer and Saugwagen product lines serving recycling, disposal, and municipal customers.

Broad incumbents

• Kärcher: Global leader in industrial cleaning equipment including industrial vacuums and suction systems. Highly comparable product category to Klaus's Fiederle suction trailer/wagon line, but operates at vastly greater scale with a broad portfolio spanning consumer and commercial cleaning.
• Hako: German manufacturer of municipal and industrial cleaning machines, including outdoor sweepers, scrubbers, and vacuum/suction equipment. Comparable to Klaus on the municipal and industrial cleaning side with overlapping end customers (municipalities, service companies).
