Klopper Therm

What Klopper Therm does

Klöpper-Therm GmbH is a Dortmund-based specialist manufacturer of custom-engineered electrical heating systems for industrial process heat applications, founded in 1928 and operating as a wholly-owned subsidiary of the Swedish NIBE Group since 2022. The company's portfolio spans three principal categories: heaters (hot water generators, process heaters, air heaters, electric steam boilers and superheaters, molten salt heaters, Power-to-Heat systems, and cable heaters), heat tracing and surface heating (pipe trace heating, tank/container heating, ramp and anti-freeze systems), and system control — anchored by the proprietary UNIPLEX III controller with integrated safety temperature limiting (ATEX, SIL2) and the UNIWIN visualization platform. Power ranges extend from 100 kW to 10 MW across control-cabinet offerings.

The business model is engineering-led and project-based: custom solutions are designed and manufactured in Germany, then sold through direct sales from Dortmund for key accounts alongside an international distributor network covering 15+ countries across Europe, Asia, Africa, and the Middle East. Pricing is quote-based and not publicly disclosed, with long sales cycles and full-service delivery from planning through commissioning and lifecycle maintenance. Customers are predominantly industrial enterprises — German municipal utilities (Stadtwerke Lemgo, Tübingen, Offenbach, Schwerin for Power-to-Heat), chemical and petrochemical processors, tank and silo builders, mechanical and plant engineers, and cold-storage operators — with certifications (ATEX, PED, ASME VIII, IECEx, ISO 9001/14001, SCCP) enabling access to demanding regulated and export markets. Revenue and headcount figures are not publicly disclosed.
