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 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.
