Mahler AGS

What Mahler AGS does

Mahler AGS GmbH is a privately held Stuttgart-based machinery manufacturer founded in 1950 that designs, engineers, manufactures, and commissions on-site industrial gas generation and purification plants. The company serves industrial end-users across petrochemical and refining, metallurgical and steel, glass and enamel, chemical and pharmaceutical, food, electronics, and technical-gas supply verticals, with more than 4,500 cumulative plants delivered worldwide.

Its core technology stack rests on Pressure Swing Adsorption (PSA), Vacuum Pressure Swing Adsorption (VPSA), Steam Methane Reforming (SMR), Steam Reforming of Methanol, membrane separation, and protective-gas combustion. The product portfolio comprises eight branded offerings: Hydroform C (SMR hydrogen), Hydroform M (methanol-reforming hydrogen), Hydroswing (hydrogen PSA), Oxygen VPSA Plants, NITROSWING (nitrogen PSA, up to 99.99% purity), BIOSWING (biogas upgrading with up to 98% methane recovery), Process Gas Membranes, and HN/HNX protective gas systems (350-1,200 Nm³/h with adjustable hydrogen content).

The business model combines custom-engineered project sales (hardware revenue), full-scope project management and engineering services, and long-term service, maintenance, modernization, remote monitoring, and spare-parts supply for plants that can exceed 40 years of operating life. Go-to-market is exclusively direct enterprise field sales with technical sales engineers and project managers handling each inquiry from feasibility through commissioning, supported by industry events, a technical content-driven website, and a LinkedIn presence. Pricing is project-based, not publicly disclosed, and structured as multi-year contracts tied to plant capacity, technology type, and customization scope. The company is TÜV SÜD certified, registered in Stuttgart (HRB 11378), and claims global delivery and commissioning capability.

Products and services

• Hydroform C (Steam Methane Reforming Hydrogen Plant) Hydrogen plant that produces hydrogen through catalytic steam methane reforming (SMR), reacting methane with steam at high temperatures. Designed for industrial hydrogen generation for industry, energy, and mobility applications.
• Hydroform M (Steam Reforming of Methanol Hydrogen Plant) Hydrogen plant that generates hydrogen from methanol and water using catalytic steam reforming of methanol, providing an alternative feedstock pathway for industrial hydrogen production.
• Hydroswing (Hydrogen Pressure Swing Adsorption Plant) Hydrogen Pressure Swing Adsorption (PSA) system that purifies and recovers hydrogen through adsorption-based separation, delivering high-purity hydrogen with scalable capacity for industrial, energy, and mobility use.
• Oxygen VPSA Plants On-site oxygen generation systems using Vacuum Pressure Swing Adsorption (VPSA) to separate oxygen from ambient air, producing oxygen up to 94 vol.-% purity for industrial and medical applications at capacities of 300–5,000 Nm³/h.
• NITROSWING (Nitrogen PSA Plants) Pressure Swing Adsorption nitrogen generation plants that produce on-site nitrogen from ambient air with purities up to 99.99 vol.-% (N2 + Ar) for inerting, packaging, and storage applications at capacities of 200–4,000 Nm³/h.
• BIOSWING (Biogas Upgrading Plants) PSA-based biogas upgrading plants that convert raw biogas or landfill gas into high-purity biomethane with methane recovery up to 98% and biomethane purity >96 vol.% CH4, suitable for grid injection, combined heat and power (CHP), or industrial use at capacities of 500–5,000 Nm³/h.
• Process Gas Membranes Compact membrane systems for gas separation and recovery, including hydrogen recovery, synthesis gas ratio adjustment, and separation of methane, helium, carbon dioxide, oxygen, and nitrogen from process or exhaust gas streams, with recovery up to ~98–99% and purity up to 99 vol.-%.
• HN/HNX Protective Gas Systems Protective gas generators that produce nitrogen-based atmospheres with adjustable hydrogen content (1–12 vol.%) via controlled combustion of hydrocarbons, designed for heat treatment applications at capacities of 350–1,200 Nm³/h.
• Project Management & Engineering Solutions End-to-end project management covering engineering, procurement, construction, and commissioning, with 3D-based design and modular project execution delivered to industrial customers.
• Modularization Prefabricated modular plant construction service that delivers standardized, pre-built units manufactured in controlled workshop environments, enabling faster, safer, and higher-quality plant building at customer sites.
• Procurement, Manufacturing & Delivery Complete supply chain management, in-house manufacturing, and global logistics services covering road, sea, and air delivery of plants to customers worldwide.

Direct peers

• Messer Group: Privately held German industrial gases group with engineering and on-site gas generation (hydrogen, oxygen, nitrogen) capabilities. Highly comparable in heritage, German Mittelstand roots, and direct overlap with Mahler AGS's hydrogen and oxygen/nitrogen plant EPC business.
• Carbotech: German specialist in biogas upgrading and gas treatment (PSA, membrane, water scrubbing) with a comparable mid-scale EPC model. Directly comparable to Mahler AGS's BIOSWING biogas upgrading offering and similar German Mittelstand positioning.
• EnviTec Biogas: German EPC and technology provider for biogas plants, biomethane upgrading, and gas-to-grid injection. Directly competes with Mahler AGS's BIOSWING product line and shares the German engineering heritage.
• Xebec Adsorption: Canada-based provider of PSA-based gas purification, oxygen, nitrogen, and hydrogen generation systems for industrial and renewable applications. Directly competes in the same on-site generation technology categories as Mahler AGS, with comparable product breadth.

Broad incumbents

• Linde Engineering (Linde plc): Engineering arm of Linde plc providing hydrogen, syngas, and air-separation plant EPC at global scale. Overlaps directly with Mahler AGS's Hydroform, Hydroswing, and VPSA product lines but offers a far broader portfolio including large-scale air separation and petrochemical process technology.
• Air Products: Global industrial gas major with significant on-site hydrogen, oxygen, and nitrogen generation EPC activity and a major renewable hydrogen roadmap. Competes with Mahler AGS for large industrial hydrogen and oxygen plant contracts but at significantly larger scale.
• Hitachi Zosen Inova (HZI): Swiss-based EPC for energy-from-waste and biogas upgrading plants (Kompogas, BiogasZentrum). Overlaps with Mahler AGS's biogas upgrading business, particularly for landfill and waste-to-grid projects, but at larger scale and with broader waste-management scope.

Emerging players

• thyssenkrupp nucera: Specialist EPC for hydrogen production via alkaline water electrolysis, with growing industrial hydrogen plant pipeline. Competes with Mahler AGS's hydrogen plant portfolio (particularly future-oriented green H2 contracts) but focuses on electrolysis versus Mahler AGS's SMR/methanol/PSA base.
• Nel ASA: Norwegian hydrogen technology and manufacturing company providing alkaline and PEM electrolyzer-based hydrogen plants. Adjacent competitor in on-site hydrogen generation, focused on green H2 from electrolysis rather than fossil reforming.
• Generon (IHI / Generon IGS): US-based manufacturer of membrane and PSA-based nitrogen, oxygen, and hydrogen generation systems. Adjacent competitor in the on-site industrial gas generation space, particularly for nitrogen and process gas membrane separation, overlapping with Mahler AGS's NITROSWING and Process Gas Membranes lines.
