Oeltechnik Service Gmbh

What Oeltechnik Service Gmbh does

Oeltechnik Service GmbH is a German specialist service provider for process equipment, oil systems, and condensation systems, headquartered in Waghäusel, Baden-Württemberg. The company is a wholly-owned subsidiary of the OELTECHNIK Group (parent: Gesellschaft für OELTECHNIK mbH) and operates as the group's dedicated service arm alongside sister entities TubeTech GmbH (Plauen) and Oeltechnik France S.A.R.L. Its core offering spans five professional-service lines: maintenance and repair (including on-site leak repair), spare-part procurement, retrofit and modernization of legacy equipment, professional cleaning and inspection, and certified non-destructive testing (ZfP) covering MT, PT, UT, VT, and RT methods at levels 1–3, plus LT at levels 1 and 3. A structured training and certification program (VT, MT, PT, UT) under EN ISO 9712, delivered in cooperation with Vector München and certified by SECTOR Cert, adds a recurring educational revenue stream. Customers are industrial enterprises across chemical, power-plant, steel, gas, refinery, and environmental/recycling verticals, primarily served through on-site field-service delivery in Germany.

The business model is enterprise B2B field services sold via direct sales relationships and supported by trade-fair presence (e.g., Leuna Dialog 2025). Revenue is generated primarily through professional-services engagements and spare-parts supply, with pricing structured per project or per training participant (e.g., €3,230 for a VT Level 1+2 course). The company's competitive position rests on four major industry certifications (DIN EN ISO 9001:2015, WHG, AD2000, EN ISO 3834-2), deep domain specialization in oil/condensation/heat-exchanger systems, and in-house welding supervision capability. Operating scope is regional (Germany), with the parent group providing broader European reach through France.
