GLASS-TO-METAL SEALS

Power Feedthroughs

Powering energy and other harsh industry applications.

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.

Ofen in the form of single feedthroughs or terminal plates, our glass-to-metal seals are available in single-pin or multi-pin configurations tailored to exact customer needs. Using optional silicone or silicone-free insulators on top of the glass, the leak current can be further reduced to a minimal level. To protect the products from environmental influences we provide various surface treatment options.

Glass-ceramics feedthroughs with copper conductors

Using copper as the conductor material, high ampere connectors can be achieved with relatively small diameter pins. We can offer copper or copper-based feedthroughs in combination with stainless steel housings for this purpose.
