Vacuum furnace Vector UHV

chamberheat treatmentbrazing

Description
The Vector UHV is a horizontal single‑chamber vacuum furnace dedicated to vacuum brazing of electrical switch components such as vacuum interrupters and vacuum circuit breakers (VCB). It is engineered for ultra‑high‑purity processing and is assembled and tested in a clean room to minimize contamination.

Features

• Horizontal single‑chamber configuration with molybdenum hot zone for high‑purity processing
• Turbomolecular pumps to achieve high / ultra‑high vacuum
• Six thyristor‑controlled temperature zones for accurate thermal control
• External gas quenching system (quenching gases: nitrogen or argon)
• Operator‑friendly computer control and monitoring system
• Standard chamber sizes: 600×600×900 mm and 1000×1000×1200 mm

Advantages

• Vacuum process acts as protective and process atmosphere, eliminating the need for reactive process gases and associated emissions
• No CO2 emissions from the vacuum process and no combustion of fossil fuels for the vacuum cycle
• Cooling gas (N2 or Ar) can be recovered and returned to the air stream, reducing environmental impact
• Reinforced thermal insulation reduces electrical consumption (approx. 20%)
• High energy efficiency: IE3 class motors, inverter control and energy management algorithms
• Systems to optimize pumping, heating and cooling consumption
• Reduced hardening deformation and downstream machining; part washing after heat treatment generally not required

Process

• Vacuum brazing of electrical switch components (e.g., vacuum interrupters, VCB)
