What VM Tarm does

VM Tarm a/s is a Danish, family-owned manufacturer founded in 1962 and headquartered in Tarm, Denmark, specializing in custom-built tank trailers constructed from stainless (rustfast/syrefast) steel and aluminium. The company produces approximately 300 trailers per year across a broad product range that includes feed tanks, slurry/manure trailers (sold under the premium TailorLine and the 2026-launched pre-configured StarLine), chemical tanks, milk tanks, vacuum/sludge tankers, fish tanks, beer tanks, special-purpose tanks, and hydraulic tractor unit constructions. Technology differentiators include an in-house developed slurry pump, a second-generation 400V AC battery-powered milk pump built with Mastervolt, a crane parking-assist system, Active Reverse Control on two axles, and a weight-optimization program that produces what the company describes as the lightest tank trailers on the market.

The business operates a direct enterprise field-sales model with named sales consultants covering Scandinavia (Denmark, Norway, Sweden, Finland, Iceland), Canada, the USA, and broader EU, plus a North American distribution partnership with Advance Engineered Products Group established in 2023. Revenue streams include one-time unit sales of custom tankers, a subscription-style service lease for slurry trailers (servicelejeaftale), an aftermarket spare-parts catalogue, and direct service and repair across Denmark, Sweden, Norway, and Finland (with a 24-hour mobile service team). Approximately 35% of production is exported to Norway, with Germany and North America identified as growth markets. The company is privately held by founder-era owner Knud Lauritsen, with Holger Ross Lauritsen serving as CEO. Operating investments in 2023–2026 include a 1,000 m² service hall, a dedicated slurry assembly hall, an office expansion, and a ~21–23 metre welding tower, alongside a near-100% CO2-neutral production claim, four consecutive years of revenue records, and ongoing headcount growth.
