Geotec

What Geotec does

Geotec Bohrtechnik GmbH is a German machinery manufacturer specializing in the design and production of vertical drilling rigs under the ROTOMAX brand. Founded in 2016 and headquartered in Nordkirchen, the company manufactures most components in-house, with approximately 80% vertical integration supported by CNC milling, machining centers, and certified welding operations under DIN EN ISO 9001:2015 and DIN EN 1090. Its product portfolio comprises four series — M (compact, 50 kW), Li (mid-range, 72-100 kW), XL (heavy-duty, up to 225 kW), and TY (truck-mounted on Mercedes-Benz, Scania, MAN, Volvo, Tatra, and Iveco chassis) — covering more than 15 model variants and supporting ten distinct drilling methods including CFA/endless screw, double-head, DTH, air lift, dry, direct flush, rotary core, percussion, auger, and suction drilling.

The company's commercial model is sales-led and project-based: equipment is sold direct through three regional sales managers covering Western Germany and export, Eastern Germany/Bavaria/Austria/Benelux/UK, and Poland, with pricing determined by custom quotation per configuration. Recurring revenue is generated through original spare parts, a service-and-maintenance offering, and a service-partner network spanning 20+ locations across Germany, Austria, Switzerland, Poland, and the UK. End customers are drilling contractors, well-construction firms, geothermal installers, and geotechnical engineering companies, served via a vertical-segmentation approach targeting well construction, geothermal energy, and geotechnics use cases.

Distribution combines direct field sales with ecosystem marketing through trade shows (bauma, Bohrtechniktage), the co-hosted Driller Days partnership with STÜWA, multilingual digital presence, and a branded e-commerce shop. The company is privately held by management (Norbert Zumholz as legal representative), with no disclosed external investors, parent company, or public funding events.

Core offering

Geotec Bohrtechnik GmbH designs and manufactures the ROTOMAX family of vertical drilling rigs for applications in geothermal energy, geotechnics, and well construction (Brunnenbau). The company produces approximately 80% of components in-house at its Nordkirchen facility, including CNC-machined and welded assemblies, and sells customized rigs directly through regional sales managers across Germany, Austria, Switzerland, Poland, Benelux, and the UK. In addition to new equipment, Geotec supplies original replacement parts and provides service, maintenance, and technical support through its own service team and a network of service partners.

Product overview

Geotec's product portfolio centers on the ROTOMAX family of drilling rigs, organized into four size-based series — M (compact/mini), Li (mid-range), XL (large), and TY (truck-mounted) — each available in multiple variants optimized for specific drilling methods and applications. The M series is the most compact entry at 50 kW / 2.9–3.5 t, serving water wells, geothermal probes, and exploratory drilling. The Li series (72–100 kW / ~6.5 t and above) bridges compact and heavy-duty applications with variants including the Li B (geotechnical casing specialist), Li CM (casing mast for overburden drilling), and others. The XL series (106–225 kW / 9–18 t) covers heavy-duty geothermal and well construction, including double-head models (GTC/GTCi) for simultaneous drilling and casing, casing mast (CM), geotechnical (B), and versatile all-round (ECO) variants. The TY series comprises truck-mounted rigs on carrier vehicles from Mercedes-Benz, Scania, MAN, Volvo, Tatra, and Iveco, including 4x4 and 6x6 wheeled configurations and the UNIMOG-based U 500. All ROTOMAX rigs support multiple drilling methods — including continuous flight auger (CFA/endlosschneckenbohren), double-head drilling, DTH (down-the-hole), air lift, dry drilling, direct flush, rotary core, cable percussion, and auger drilling — and are manufactured in-house in Germany with approximately 80% vertical integration. The portfolio is complemented by a used equipment market, original spare parts, and full-service maintenance.
