Temescal FC2000 / BJD-2000 Bell Jar Deposition System

Convertible Bell Jar for Small-Scale Production and R&D Applications

Temescal’s BJD-2000 and FC-2000 are versatile evaporation systems that accept a variety of accessories to meet almost any requirement. Engineered for efficient operation and clean room compatibility, these systems combine maximum flexibility with ease of use. The FC-2000 is a fast- cycle, load-locked system that allows the source to remain under vacuum during substrate reloading. The BJD-2000 is non-load-locked.

Convenient Maintenance

The offset pumping port, the hinged door panels, and the swingout source tray are high-value maintenance features in Temescal bell-jar systems. The offset pumping design reduces unscheduled downtime by minimizing the possibility of debris entering the pumping module. The hinged door panels open to the pumping system and the vacuum chamber. The electric hoist and the swing-out source tray facilitate access for evaporant reloading, cleaning, and maintenance. Access to the water manifold, the bellows-sealed high-vacuum valve, and other pumping system components is also simple and direct.
