Maschinen- Und Apparatebau Hagen Gmbh

What Maschinen- Und Apparatebau Hagen Gmbh does

Maschinen- und Apparatebau Hagen GmbH, trading as m+a, is a German specialty manufacturer founded in 1960 and headquartered in Breckerfeld (registered in Hagen), producing ventilation ductwork for the European building-services market. Its core product is the Ovale Wickelfalzrohr — an oval spiral-seamed duct made from hot-dip galvanized sheet steel — offered in more than 100 dimensions together with a full fitting range, plus adjacent systems for hall heating and roof ventilation. The firm is family-influenced, with three managing directors including two members of the Köser family, and operates without external investors.

Revenue mechanics are project-tied: products are specified by mechanical engineers and architects and pulled through the supply chain by HVAC contractors, rather than sold on subscription or recurring service contracts. The company commercializes through a combination of direct specification support, a multi-property digital ecosystem (mua.de, luft systembau.de, lueftungsdesigner.de) and a CADENAS-published VDI 3805 BIM/CAD catalogue that embeds components directly into design software. Reference customers span automotive (Audi AG), cultural infrastructure (Elbphilharmonie Hamburg, Berliner Dom), research (Max-Planck-Institut), food retail (EDEKA, REWE) and the hotel/hospital/university segment.

Distribution is concentrated in Germany and the EU, with no disclosed overseas manufacturing footprint. Strategic posture has shifted from a single-product specialist toward a system supplier and design-element brand, evidenced by the Innogration/CEILTEC prefabricated-ceiling partnership and the architectural repositioning of oval ductwork as a visible interior feature.

Direct peers

• Zehnder Group: Swiss-listed manufacturer of ventilation and indoor climate solutions, including air distribution ductwork. Comparable in selling design-oriented, energy-efficient ventilation to architects and HVAC contractors across European commercial buildings.
• Aldes Group: French ventilation and indoor air quality manufacturer offering ductwork and air distribution systems for residential and commercial markets. Comparable product range and customer base to m+a in EU commercial/institutional construction.
• Lindner Group: German manufacturer of building interior systems including integrated HVAC and ceiling solutions. Comparable to m+a in serving modular/prefab ceiling applications and overlapping in modern office building projects where mechanical systems are integrated into building interiors.
• Systemair AB: Swedish-listed ventilation manufacturer producing ductwork, fans, and air handling units for the European market. Directly comparable in duct product range and target customer base (HVAC contractors, specifiers) and competes in overlapping EU commercial construction projects.
• Fränkische Rohrwerke: German manufacturer of corrugated and spiral pipe systems used in ventilation, drainage, and industrial applications. Comparable German specialty manufacturer producing spiral-wound duct and pipe products for European construction and industrial customers.
• Swegon Group AB: European indoor climate and ventilation manufacturer offering air distribution products including ducts and diffusers. Targets the same commercial/institutional project segment as m+a with overlapping value proposition around energy-efficient, design-integrated air distribution.

Broad incumbents

• FläktGroup: Major European HVAC and air handling equipment manufacturer with deep presence in Germany and the Nordics. Competes with m+a in commercial/institutional ventilation projects and supplies duct-integrated air handling solutions for the same specifier base.
• TROX GmbH: German-headquartered global leader in ventilation and air handling components, including air terminal devices, grilles, and duct-related products. Much larger and broader portfolio than m+a, but competes in the same European HVAC air distribution value chain serving architects and engineers.
• Wolf GmbH: German HVAC systems manufacturer (part of Carrier) producing heating, ventilation, and air conditioning equipment. Competes in the German commercial HVAC market and serves many of the same contractors and engineering firms that purchase ductwork from m+a.

Others

• Camfil AB: Swedish air filtration and clean air solutions provider serving commercial, healthcare, and industrial ventilation projects. Adjacent rather than directly competing, as Camfil focuses on filtration rather than ductwork, but addresses the same end-customer value chain in indoor air quality.
