What Helmholz does

Helmholz GmbH & Co. KG is a German industrial automation technology company founded in 1991 and headquartered in Großenseebach, Bavaria. The company specializes in industrial networking and communication hardware for mid-sized machinery and plant manufacturers (Mittelstand) across Germany and the EU. Helmholz's product portfolio spans four core lines: (1) Industrial Remote Solutions — REX Ethernet routers and the myREX24 cloud portal for secure remote maintenance; (2) Industrial Ethernet — FLEXtra managed and unmanaged PROFINET/Ethernet switches plus the WALL IE NAT-Gateway/Firewall for OT security; (3) Fieldbus Applications — gateways and couplers supporting PROFINET, PROFIBUS, EtherCAT, CAN-Bus, ModbusTCP, EtherNet/IP, and MQTT protocols; and (4) the TB20 Decentralized Fieldbus I/O System with bus couplers and modular I/O. Additional offerings include S7-compatible components, diagnostic tools (Cabinet Guard, Cable Guard, Test Accesspoint TAP IE), and SPE/IP67 switch variants. The underlying technology stack is built on industrial Ethernet and fieldbus protocols with IEC 62443 compliance, and the company positions products around ease of integration without additional software tools.

Business model is hardware-driven B2B sales executed through three channels: a direct e-commerce storefront at helmholz.de, a direct sales team reachable via phone and email, and distributor partnerships (notably RS Components GmbH for global reach). Hardware is sold on a one-time/perpetual-license basis with prices ranging from approximately €94 for unmanaged Ethernet switches to €741 for managed PROFINET switches and €581-€606 for gateways, priced in Euros exclusive of VAT. A secondary revenue stream comes from product training services (online, on-site at customer location, or at Helmholz headquarters). The customer base, evidenced through public case studies, spans diverse mid-sized industrial buyers including thyssenkrupp Dynamic Components, Grünbeck Wasseraufbereitung, maxon motor, EREMA, Greenland Seafood, Drahtwerk Elisental, Spierings Service, Wickert Maschinenbau, BUZIL-WERK Wagner, Machinor S.A., MS Ultraschall Technologie, and Westerwälder Holzpellets. The company is privately held in a GmbH & Co. KG structure with managing directors Carsten Bokholt and Karsten Eichmüller, no disclosed institutional investors, and operations confined to EU countries with shipping restrictions to RUS and BLR.
