What Huss Group does
HUSS Group is a manufacturer of diesel exhaust emission after-treatment systems specializing in retrofit diesel particulate filter (DPF) systems. Founded in 1925 in Germany as HUSS Maschinenfabrik and pioneering diesel particulate filtration since 1985, the company operates through a dual-entity structure: HUSS Inc., headquartered in Palm Springs, California, managing North and South American business since 2005, and HUSS tec GmbH in Großröhrsdorf, Germany, managing European and export operations. The company is privately held, controlled by Dr. Thomas Rahn, and employs 51-100 people.
The company's product portfolio comprises four core DPF architectures built on Silicon Carbide (SiC) ceramic filtration technology, all delivering 99.9% filtration efficiency. The flagship MK-System uses a diesel burner for active regeneration independent of exhaust gas temperature and covers engines up to 500kW. The MD-System provides hybrid active/passive regeneration via diesel post injection (up to 200kW), the MC-System offers passive catalytic regeneration (up to 500kW), and the W-System uses exchangeable cartridges with external oven regeneration (up to 100kW). Application variants target on-road vehicles, off-highway construction and mining equipment, transport refrigeration units (TRUs), and special applications including rail and stationary generator sets. The company holds CARB, VERT, BAFU, MSHA, and TRGS554 certifications.
HUSS generates revenue through one-time hardware sales of filter systems plus installation and maintenance services delivered via an extensive US certified dealer network (TRU Partners and On/Offroad Partners) and direct international sales support from Germany. Named customers span logistics OEMs (Jungheinrich, Mitsubishi, Yale, Kalmar), construction equipment (Caterpillar, Liebherr), rail (ÖBB Austrian Railroad, Plasser & Theurer), transportation (Mercedes Benz city buses and Econic garbage trucks), and government projects (the New York School Bus Project covering 1,400+ MK-System retrofits). Pricing is project-specific and delivered through dealer quotes rather than public disclosure.

Huss Group product offering
Product offeringCore offering
Huss Group manufactures diesel particulate filter (DPF) systems for retrofit markets, offering four distinct technology platforms — MK-System (active diesel-burner regeneration), MD-System (hybrid active/passive via diesel post-injection), MC-System (passive catalytic coating), and W-System (exchangeable cartridges with external oven regeneration). All systems use Silicon Carbide (SiC) ceramic filtration media and are designed for off-highway equipment including forklifts, construction machinery, transport refrigeration units, mining vehicles, and rail applications, addressing engines from 100 kW to 500 kW.
Product overview
Huss Group offers four distinct diesel particulate filter systems for retrofit markets, all utilizing Silicon Carbide (SiC) ceramic technology with closed filter designs. The portfolio consists of: MK-System (diesel burner-based active regeneration, engine-independent), MD-System (hybrid active/passive with diesel post injection), MC-System (catalytic coating for passive continuous regeneration), and W-System (exchangeable cartridges with external oven). The MK-System is the company's flagship, covering off-highway applications including forklifts, construction equipment, generator sets, ships, rail, and special applications. Systems range from 100kW to 500kW engine capacity depending on model. All products are designed for the 'off-highway' retrofit market segment, requiring no exhaust aftertreatment ex-works.

Products and services
- MK-System Active regeneration diesel particulate filter system with an on-board diesel burner that operates independent of exhaust gas temperature. Stainless steel filter modules use Silicon Carbide (SiC) ceramic media to achieve 99.9% filtration efficiency. Covers engines up to 500 kW and regenerates in 25–40 minutes when the engine is shut off. Targeted at off-highway, on-road, TRU, and special-application retrofits.
- MD-System Hybrid regeneration diesel particulate filter using engine-external diesel post-injection through a vaporizer. Combines active regeneration (when exhaust temperatures are low) and passive regeneration (when temperatures are sufficient) to maintain filter cleanliness. Achieves 99.9% filtration efficiency and covers engines up to 200 kW.
- MC-System Passive regeneration diesel particulate filter using a precious-metal catalytic coating on filter channels that enables soot burn at temperatures below the regular soot ignition point. Provides continuous regeneration during driving when exhaust temperature exceeds 270°C in at least 40% of working time. Achieves 99.9% filtration efficiency and covers engines up to 500 kW.
- W-System Exchangeable cartridge diesel particulate filter system for smaller engines up to 100 kW. Uses Silicon Carbide (SiC) ceramic cartridges that are regenerated externally via a shared electrical oven, allowing multiple vehicles to share one oven. Achieves 99.9% filtration efficiency.
- MK-System for Offroad Applications Application variant of the MK-System configured for off-highway construction and mining equipment. Features active regeneration with diesel burner and a robust stainless steel design; MSHA-approved for mining use. Requires no plug-in and no fuel-borne catalyst.
- MK-System for Onroad Applications Application variant of the MK-System for on-road diesel vehicles. Operates independent of exhaust gas temperature, making it ideal for high stop-and-go ratio applications such as city buses and refuse trucks.
- MK-System for TRU Applications Application variant of the MK-System designed for Transport Refrigeration Units (trailer-mounted and bobtail configurations). Offers automatic regeneration in trailers and parked regeneration in bobtails. CARB Level 3+ compliant with 85%+ filtration efficiency.
- MK-System for Special Applications Application variant of the MK-System for mining (MSHA-approved) and other specialized industrial applications. Includes backpressure monitoring, automatic regeneration alerts, and 25–40 minute regeneration cycles.
- Filter System Installation and Maintenance Services Professional services delivered through the certified dealer network for filter selection support, on-site installation assistance, and ongoing repair and maintenance of installed HUSS diesel particulate filter systems.
