I.M.A.

What I.M.A. does

I.M.A. H.-D. Gröschler GmbH is a German industrial engine distributor and solutions provider headquartered in Leopoldshöhe and founded in 1989 by Hans-Dieter Gröschler following his prior tenure in the Ford industrial engine business. The company holds exclusive distribution rights for Kubota industrial diesel, gasoline, and gas engines in Germany across the 19–157 kW power range and complements this distribution franchise with proprietary I.M.A. Power Packs (Open Power Unit and Closed / SB-EVO Silent Box variants) that integrate Kubota Common Rail engines with EU Stage V-compliant exhaust aftertreatment. Adjacent product lines include tailor-made retrofit and rooftop air conditioning systems for heavy machinery cabs, the co-developed SilentBoy generator series, original spare parts, and engine accessories such as clutch bells, front-end bearings, and radiators.

The business operates a sales-led B2B model: direct OEM sales for engine integration projects and Power Pack customization, channel sales through more than 30 authorized service partners across Germany for parts, maintenance, and warranty, plus an e-commerce storefront (shop.i-m-a.de) for accessories and smaller orders. Customer segments are OEMs in agriculture, construction, forestry, and energy, with additional downstream exposure to machine operators and fleet owners retrofitting AC or replacing engines. Technical consulting — application validation, vibration testing, thermal testing, duty cycle analysis, 3D CAD design, and electrical/control integration — is bundled with engine sales to reduce OEM development effort.

Operationally, I.M.A. maintains a headquarters and primary production/storage facility in Leopoldshöhe and a secondary Wadersloh (Liesborn) site dedicated to Power Pack production, container handling, and training. The company is privately held by founder Hans-Dieter Gröschler with two Managing Directors (Florian Hochstadt, Janine Berlinghoff) handling day-to-day operations, holds ISO 9001:2015 certification, and grew its service infrastructure materially in 2024 by taking over the Kubota service network in Germany.

Broad incumbents

• Volvo Penta: Division of Volvo Group supplying diesel engines and complete drivelines for industrial, construction, marine, and power-generation applications. Broad incumbent with overlapping Stage V / Tier 4 Final engine portfolio and European OEM customer base to I.M.A.'s distribution and Power Pack business.
• Wärtsilä: Finnish large-engine manufacturer serving marine, energy, and industrial markets with diesel and dual-fuel engines and gensets. Broad incumbent offering overlapping engine and power-generation capabilities to I.M.A.'s energy and industrial customer set, though at much larger scale.
• FG Wilson (Caterpillar): Global diesel and gas generator set manufacturer distributed through a large dealer network. Broad incumbent to I.M.A.'s SilentBoy line, with deeper global reach but less specialization in sub-20 kVA Kubota-powered units.
• INNIO Jenbacher: Austrian-headquartered manufacturer of large gas engines and generator sets for power generation, CHP, and gas applications. Broad incumbent to I.M.A.'s power-generation business via the SilentBoy line, addressing larger kVA classes than I.M.A.'s Kubota-based gensets.

Direct peers

• Pramac: Italian generator and power equipment manufacturer with branded gensets and integrated power solutions. Direct peer to I.M.A.'s SilentBoy generator business, addressing European and global markets with packaged diesel/gas gensets of similar power class.
• MWM (Caterpillar Energy Solutions): German-based gas and diesel engine manufacturer and genset packager for power generation, gas, and industrial applications. Direct peer to I.M.A.'s SilentBoy generator and Kubota gas/diesel engine distribution lines, with overlapping customers in decentralized power and CHP.
• Deutz AG: Cologne-based manufacturer of diesel and gas engines for industrial, agricultural, construction, and automotive applications. Direct peer to I.M.A. — both supply compact-to-mid-range industrial diesel engines with service support to European OEMs in overlapping end markets.
• Hatz Diesel: German ( Ruhstorf) manufacturer of single- and multi-cylinder industrial diesel engines, including complete power packs and Silent-Power-Sets. Direct peer to I.M.A., competing in the same compact industrial engine and integrated power pack category with similar European OEM customers.

Emerging players

• Yanmar (Industrial Engines): Japanese manufacturer of compact industrial diesel engines, power packs, and generator sets with strong European presence. Comparable Asian competitor to Kubota that I.M.A. distributes in Germany, with similar product positioning in sub-157 kW industrial diesel and integrated solutions.
• Kohler Engines: Global manufacturer of small-to-mid-range gasoline and diesel engines (including the Lombardini line) for industrial, agricultural, and construction applications. Comparable to I.M.A. in engine power class and integrated power-pack offering, though Kohler operates its own pan-European distribution.
