With the integration we are creating valuable synergies in a technologically regulated environment and access to new applications and markets."

Over the course of 25 years, the medium-sized company has developed into a specialist for engineered solutions in electrical heating technology and today has established relationships with manufacturers in the field of vacuum coating, environmental and recycling machines as well as process and laboratory technologies in Europe.

Mr. Dino A. Trslic, CEO of the ARBAnova Family Foundation, emphasizes: "We are looking forward to working with the entire ISOHEAT team, whom we warmly welcome in our ARBAnova Family Foundation with their very special know-how."

With its unique know-how in the field of design and production as well as on the basis of the comprehensive portfolio of high-quality heating components and certified heating systems, ISOHEAT develops customer-specific solutions also for use in hazardous areas.“ 

The shared vision, combined with expertise and strategic strength, offers great benefits for employees and customers. Emil Schmidt, co-founder and managing director of ISOHEAT GmbH, underlines this unique opportunity: "The technical expertise in electrical heating technology and the long-term orientation form an ideal constellation for the future. We will use this momentum to take our existing products and markets to the next level."

Norbert Baumann and Walter Wagner, co-founders and managing directors of ISOHEAT GmbH welcome the merger and explain: "For our 25-year-old company and for our employees, the takeover by the ARBAnova Family Foundation in Würzburg sets the course for the next phase of development and creates a stable basis for sustainable growth".
