For more than 65 years we have been a leading manufacturer of radiator valvesfor oil-immersed transformers. Our product range includes radiator valves, protection devices, dehydrating breathers, welding parts for tanks as well as accessories for pressure control and oil level indication.

What’s the formula for success that made us become a reliable and long-term business partner for many leading transformer manufacturing companies of today from the time when we established business in 1949? It’s our partners trust in our expertise and in the continuous performance of our network. We have been establishing subsidiaries and partner companies in order to deliver best service and to be able to live up to the rising standards of high quality transformer components. This close cooperation with our partners allows us to meet our own demands in terms of quality and costs of pre-products and finished components within our supply chain.

Nowadays we manufacture with more than 100 employees in Germany and Turkey butterfly valves and dehydrating breathers for power transformers as well as oil level indicators, moisture holders, pressure relief devices, and tank components for oil-immersed distribution transformers.
