THERMONIE > Services


For decades we have been developing highly customized solutions together with our customers to fit their electrical component needs within new or existing products and applications. As our customer you benefit from the following services:

Technical Consultation

Our industry- and product-knowledge, our longstanding, close and collaborative relationships with our ISO 9001 and partially IATF 16949 certified partners as well as the strong background in electrical engineering of our technical team are only a few illustrations for the fact that we are uniquely capable of being your partner in any questions regarding the development and specification of your new or existing products and applications.

Specification and Production of Customer Specific Products

We understand that the highly standardized components offered on the market oftentimes cannot satisfy our customers’ growing demands for the supply of integrated systems or components that are specifically customized to their applications.

Therefore, THERMONIE has been innovating in this field since the early 1990’s.

Quality Assurance

By conducting our own quality assurance we can guarantee that our products satisfy our customers’ high standards. Our quality assurance closely collaborates with the quality assurance systems in place at our manufacturers. We visit and control the manufacturing facilities of our manufacturers on a regular basis and conduct audits if needed. As a member of the German VDE we support our manufacturers in the VDE’s sign approval process.

Account management, warehousing, and logistics:

Our capable sales team is happy to assist our customers in any question they may have.

We use our own extensively stocked warehouse to ensure that we meet our customers’ demands in a dependable and “just in time” fashion. Even short notice demand alterations can be fulfilled without any major difficulties or delays. The location of our headquarter in Hamburg, with its own airport and port, enables us to work together with a large variety of powerful logistics providers and to thereby get access to cost- and time-efficient national and international transportation of our products.
