Sight glasses
refrigeration

In compliance with the EC Pressure Equipment Directive, our company is certified to AD2000 WO.
In accordance with this standard, we manufacture a wide range of highly reliable sight glasses and measuring glasses for electro-optical level detection of e.g. oil or coolant, as well as current feedthroughs for air conditioning applications as screw fittings and with flanged housings.

The current feed-throughs and sight glasses with their particularly robust clear glasses are designed as pressure glazing and are suitable for a wide range of demanding applications and extreme ambient conditions with guaranteed high-pressure resistance.

We look forward to your inquiry

Refrigeration/air conditioning technology, compressors, heat pumps, industrial control and process technology

Vacuum-capable steels and stainless steels, iron-nickel alloys, Kovar, glasses and glass ceramics are processed.
The materials used offer complete hermetic and pressure-tight protection.

Depending on the application, the screw fittings and flange housings are made of electroplated steel or electrolytically polishable stainless steel. Depending on the type, the current-carrying pins are nickel-plated and gold-plated or rhodium-plated, or copper-plated and silver-plated if required.

Depending on customer requirements, the surface of the glass is specifically profiled to improve the visibility of the liquid level.
