The subgroup comprises separate companies located in Germany, Poland and Brazil and has sales representations in more than 30 countries. All these resources are specifically focused and concentrated on these types of heat exchangers. For more than 40 years, with ever increasing success, they have developed, designed, manufactured and supplied products for a large number of different industrial applications, such as:
- Transformer oil-, water- and air coolers as single units or entire plants for the generation, transportation and distribution of electrical energy.
- Shell & Tube heat exchangers in a Double-Tube-Technology layout as security coolers.With this technology leakage can be detected at the very earliest possible moment that media mixing and contamination can be avoided.They are also used for the cooling of transformer oil, gear and turbine oil as well as in the Food and Chemical industry.
- Heat exchangers for air treatment, such as coolers, heaters or condensers, including, as required, additional components such as measuring devices through to complete cooling plant solutions.
- Transformer oil pumps in series design or as a special solution for traction applications.
- Shell & Tube heat exchangers with 20 % higher thermal performance compared to conventional layout.
