UHV Systems

Löwener - UHV Systems

UHV system used for degassing of infra red camera CCD`s in their capsules. A series of smaller individual object chambers are attached to a larger main chamber. Each chamber has its own heating cover and regulator. All temperatures are monitored dual places for redundance and to minimize the risk of damaging the objects. The ultra high vacuum level needed for this application is obtained by an ion pump.

Process/Filling

Löwener - Combined System

Combined system for evacuation and leak testing of a heat exchanger. Combined system for evacuation and leak testing of a heat exchanger as well as filling it with coolant.
