HERMETIC SEALS

Power Feedthroughs


Mainly targeted towards the needs of the refrigeration industry, the Dietze Group’s power feedthrough products serve the high-ampere hermetic or semi-hermetic domain. Usually in the form of feed-through terminal plates, our glass-to-metal seals are available in single-pin or multi-pin configuration tailored to exact customer needs. Using optional silicone insulators around the bolts, the leak-current can be further reduced to a minimal level.

To protect the products from environmental influences, we provide various surface treatment options together with our partners.
