Vacuum furnace for brazing vacuum interrupters
Vector UHV – vacuum furnace for brazing vacuum circuit breakers (VCB)
Vector is a single-chamber vacuum furnace that is dedicated to the vacuum brazing processing of electrical components, different switch components like vacuum interrupters, and vacuum circuit breakers (VCB).
These types of applications require a high-purity process atmosphere. Therefore, these furnaces are equipped with turbomolecular pumps to achieve high or ultra-high vacuum.
Moreover, due to the high purity requirements, the equipment is assembled and tested in a dedicated clean room in our workshop to minimize the risk of contamination inside the furnace system.
The Vector is a single-chamber horizontal vacuum furnace, equipped with a molybdenum hot zone dedicated for pure processing and turbomolecular pumps to achieve the required high–vacuum level. Additionally, the larger-sized furnace is equipped with an additional heating element to ensure optimal uniformity of all processed parts.
