What DTEC does

DTEC GmbH is a privately held German system integrator headquartered in Rosbach v. d. Höhe, Hessen, that designs and delivers turnkey non-destructive testing and machine-vision inspection systems for the railway industry. The company serves railway operators, maintenance depots, and train manufacturers globally, addressing the operational pain of manual inspection, vehicle downtime, and the move toward Condition-Based Maintenance (CBM) and predictive maintenance strategies. Its headquarters combines labs, workshops, and test facilities used for product development and production.

The product portfolio is organized into three proprietary series — DELFIN (ultrasonic testing, including TWC-UT, UW-UT, and DW-UT for wheel and axle crack detection), ADLER (machine vision, including TFV-MV full-vehicle and UVB-MV bogie monitoring), and EULEN (laser-based wheel profile and wear measurement) — supplemented by flagship systems such as the Vehicle Vision Gate (VG), Brake Condition Monitoring (BCM), Panto Condition Monitoring (SCM), Wheel Profile Measurement (PCM), and Underfloor Wheelset Ultrasonic Testing (UWT). Underlying technology stacks conventional and phased-array ultrasonics (UT/PAUT) with 2D/3D machine vision (PMP, line scanning, ToF, binocular vision) and deep-learning-based anomaly recognition and life-cycle prediction, supported by a data flywheel from deployed systems.

DTEC generates revenue through one-time license sales of custom-engineered inspection systems and related professional services (custom UT systems, probe holders, scanners, pilot trials, and application engineering). The company is sales-led, distributing directly to enterprise customers via field sales, and relies heavily on major industry trade shows (InnoTrans, Railway Forum, RailLive, Trako, IoT AI & Data in Rail, DGZfP) for top-of-funnel demand generation. Key strategic partners include Olympus IMS (ultrasonic technology), Windhoff Bahn- und Anlagentechnik (co-developed ScanTrain/Vision Gate offering), and SOCOMATE; the company is a member of DGZfP, and Managing Director Jianguang Guo leads a team of 11–50 employees.
