What Dinex Group does

Dinex Group, legally Dinex A/S, is a privately held Danish industrial company founded in 1982 and headquartered in Middelfart, Denmark. It specializes in heavy-duty exhaust and emission control systems for large diesel and natural gas engines, organized into three product families: Exhausts (pipes, clamps and gaskets, flex and bellows, insulation, heating and cooling, and silencers for Euro 0 to V), Emission (diesel particulate filters, Euro VI silencers, DPF reconditioning, EGR cooler repair kits, and remanufacturing services), and Mechatronics (NOx sensors, AdBlue pumps and filters, AdBlue injectors, and pressure, temperature, and particulate-matter sensors for Euro IV to VI vehicles). The company also operates a DPF reconditioning and remanufacturing capability backed by 2- to 3-year warranties, and has recently extended its scope into clean-power solutions for large engines.

Dinex sells to three primary customer segments: independent workshops and commercial vehicle service centers, commercial vehicle fleet operators, and truck/commercial vehicle OEMs (with DAF Trucks disclosed as a named full-system OEM customer). Go-to-market is indirect and partner-led, centered on the Dinex Partner Portal (shop.dinex.eu), nine country-specific regional websites covering France, Germany, Italy, Latvia, Poland, Serbia, Spain, Türkiye, and the United Kingdom, 19 distribution centers across 14 countries on three continents, and OEM direct supply. Three revenue streams are identified: aftermarket parts sales, OEM solutions, and remanufacturing services, with quote-based B2B pricing that is not publicly disclosed.

The company employs 1,800 people globally, including 140 engineers and R&D staff, operates 7 production sites and 7 technology centers, and runs a 15,000-SKU catalog that it positions as Europe's widest range for heavy-duty vehicles. It has reported a 10% revenue CAGR over the past 15 years, 95%+ product availability across its distribution network, and — in its 2024 ESG report — a 12% year-over-year CO2 reduction with 50% green electricity sourcing. Ownership is concentrated among co-founders Niels Thorborg and Torben Dinesen; no PE, VC, or public listing is disclosed.
