What Welotec does

Welotec GmbH is a German industrial IoT company founded in 1969 and headquartered in Laer, near Münster, Germany. Since April 2025, it has operated as a subsidiary of the Westermo Group within Sweden's Ependion Group. The company designs and manufactures rugged computing, networking, and cellular connectivity hardware for three primary verticals: digital electric substations, industrial machinery/manufacturing, and rail trackside infrastructure. Its core technology portfolio centers on IEC 61850-3 and IEEE 1613 certified substation automation devices (RSAPC Mk2 servers, RSAEC Mk2 edge controllers, RSAVP virtualization platform, RedFox-5728 and Lynx managed switches), Linux-based IoT Edge Gateways (EG400/500/600/800 series), industrial computers (Arrakis, Alderamin, and the AI-enabled Alrai with NVIDIA Jetson Orin NX), and Merlin 3000 cellular routers supporting 4G/LTE/5G including LTE 450 MHz for utility communications. Supporting software includes SMART EMS device management, VPN Security Suite, and the egOS Linux edge operating system.

The company's revenue model blends one-time hardware sales (configured industrial computers, switches, routers, antennas) with recurring software subscriptions (SMART EMS, VPN Security Suite) bundled into starter packages and professional services for implementation, training, and proof-of-concept engagements. Go-to-market is delivered through direct enterprise sales with consultative needs assessment, an extensive technology and channel partner network (Red Hat, Fortinet, OMICRON, Tributech, Grid to Great, FLECS, conplement), and distribution via the Westermo Group's global sales infrastructure. Customer segments are anchored in transmission and distribution system operators, utilities, system integrators, machine builders, and rail operators, primarily across Europe with global reach through Westermo's network.

Pricing is quote-based and not publicly disclosed; the company sells through an online configuration platform with multi-year contracts on hardware and annual subscriptions on software. The firm holds ISO 9001, ISO 27001, and ISO 14001 certifications, has achieved EcoVadis Platinum status in 2026, and is recognized as a Kununu Top Company for four consecutive years (2023-2026). Active participation in standards bodies (IEC, CIGRE, UCA International Users Group, vPAC Alliance, LF Energy) shapes product evolution and embeds the firm in the digital substation ecosystem.
