Operating temperature range: -190°C to +1500°C (water cooling configuration available for high-temperature working conditions)
Sealing method: Fluororubber "O"-ring for general vacuum use, or metal oxygen-free copper gasket for ultra-high vacuum and extreme temperature environments
Quality is verified at every step before delivery, with mandatory factory inspections on every unit:
🔹Vacuum leak rate test
🔹Customizable surface treatments:
Wire drawing and polishing, sandblasting and electrolytic treatment, acid pickling, electrolytic polishing, mirror polishing, and more to fit your application standards
Whether you need a chamber for PVD coating, semiconductor processing, thermal treatment, food freeze-drying, or lab research, we can tailor the design to your footprint, interface, and performance needs.
