Gas rotary union VO-0550010

for refrigerant fluids11-passagefor aeronautical applications

Overview
11-passage rotary union VO-0550010 designed to supply nitrogen and ultra-high-purity helium from a stationary interface to the rotating Azimuth and Theta axes of the BICEP Array telescope at the South Pole. Engineered for cryogenic service and continuous low-speed rotation. Includes a custom Ethernet slip ring and quick-disconnect fittings on all passages for remote instrumentation and fast maintenance.
