Dietz-Motoren

What Dietz-Motoren does

Dietz-Motoren (legal name: Dietz-motoren GmbH) is a privately held German specialty manufacturer founded in 1922 and headquartered at Kirchheimer Strasse 164, 73265 Dettingen u. Teck, Baden-Württemberg. The company operates two product lines: (1) individually customizable electric motors built on a modular Baukastenprinzip (kit-of-parts) platform that scales up to 200 kW and covers air-cooled, liquid-cooled, synchronous, smooth-shell, and special-drive variants with IE3/IE4 efficiency ratings and frequency-converter compatibility; and (2) industrial radial fans and high-performance blowers spanning the SB (high-performance blower), HR (high-pressure), GR/GT (medium-pressure with closed/open impeller), and DN (low-pressure, DN8-DN25/132) series, all with aluminum housings. Technical differentiators include UV-impregnated, UL/cCSAus-certified stator windings designed for VFD-induced stress, redundant rotation monitoring, Harting Han industrial plug connectors for plug-and-play installation, and proprietary cooling integration (separate cooling jackets on liquid-cooled motors).

The company serves commercial operators (Gewerbetreibende, §14 BGB) exclusively across industrial manufacturing and process industries, with documented end-use in drying systems, laundry machines, gas/coal/oil furnaces, paper machines, tool and plastic machines, air-cushion and extraction tables, filter and automotive extraction systems, rail vehicles, conveyor technology, and shipbuilding. Its stated operational footprint spans more than 20 countries across DACH, Benelux, Northern, Southern, Central, Eastern, and Western Europe, plus China and the United States, supported by technical documentation in ten languages.

Dietz operates a sales-led B2B go-to-market combining direct consultation (phone +49 7021 5702-111, online inquiry forms, callback scheduling) for bespoke motor engineering with a transactional online shop for standard radial fans offering 2-3 business day delivery. Pricing is quote-based and not publicly disclosed, consistent with an engineered-to-order revenue model. The company is a portfolio company of DEMH Holding (dietz-motoren Holding GmbH) and is led by CEO Dipl.-Ing. Peter C. Weilguni. No funding rounds, M&A activity, or public capital-markets events are disclosed; lead times of 10-12 weeks for motors and 6-8 weeks for fans indicate demand is currently running at or near manufacturing capacity.

Core offering

Dietz-Motoren designs, develops, and manufactures customizable electric motors (air-cooled, liquid-cooled, synchronous, and special drives, up to 200 kW with IE3/IE4 efficiency) and industrial radial fans/blowers (SB, HR, GR, GT, DN series) built on a modular platform. Sales are exclusively to commercial operators via direct consultation and an online shop, with standardized options complemented by bespoke engineering for specific industrial applications.

Product overview

DIETZ-Motoren is a drive specialist offering two core product lines: individually customizable electric motors and radial fans/blowers. The electric motor portfolio includes air-cooled motors with proprietary ribbed housing design, liquid-cooled motors with integrated cooling jacket, and synchronous motors - all built on a modular baukasten (kit) principle scaling up to 200 kW with IE3/IE4 efficiency and frequency converter compatibility. The industrial ventilation line encompasses SB high-performance blowers, HR high-pressure radial fans (variable speed via frequency converter), GR/GT medium-pressure radial fans (closed and open impeller variants respectively), and DN low-pressure radial fans (multiple sizes DN8-DN25/132). Both product families feature aluminum housings and are configurable online via Fanfinder product selector and purchasable through an e-commerce shop.
