Varian Berger 40U 19in Steel Rackmount Cabinet 4 Extra Duty Sliders Enclosure

Varian Berger 40U 19in Steel Rackmount Cabinet 4 Extra Duty Sliders Enclosure

This is a Varian / Berger 40U steel rackmount cabinet built to the standard 19-inch EIA rack specification. The cabinet was designed to house heavy-duty or lightweight rackmount modules and features four extra-duty sliders for smooth, secure module installation and removal. As shown in the photos, this unit was pulled from an active system and retains a significant amount of internally installed wiring, motors, solenoid valve assemblies, pneumatic tubing, and terminal block infrastructure — making it a substantially equipped enclosure rather than a bare-shell cabinet.

Specifications & What's Included

• Rack height: 40U
• Rack width: 19-inch EIA standard
• Frame construction: steel
• Number of sliders: 4 extra-duty sliders (visible on both interior side rails)
• Internal motor assembly: cylindrical DC or AC motor visible in upper interior compartment
• Solenoid/valve assemblies: two teal-colored solenoid valve bodies with brass compression fittings and interconnecting copper tubing
• Pneumatic/gas fittings: two threaded port fittings with blue O-ring seals on top panel (handwritten port labels visible)
• Terminal block and relay strip: multi-row terminal block assembly visible on interior left and upper sections
• Internal wiring harnesses: extensive multi-conductor wiring routed throughout the interior
• Meter/gauge panel: two-dial instrument or gauge assembly mounted internally
• Cable management infrastructure included as installed

Applications

Varian is a major manufacturer of scientific, semiconductor processing, and vacuum/analytical instruments, and this cabinet appears to have originated from a larger Varian system — likely in a semiconductor fabrication, ion implant, or industrial process control environment. The 19-inch 40U form factor is the universal standard for rackmount equipment, meaning the empty rack space can accommodate standard 19-inch rackmount gear from any manufacturer. The retained internal components — motors, solenoid valves, pneumatic fittings, and wiring infrastructure — make this useful as a donor enclosure for system rebuilds, as a wiring/plumbing subassembly source for compatible Varian platforms, or as a heavy-duty rack enclosure with an existing electrical and pneumatic backbone already in place. Organizations maintaining Varian vacuum, semiconductor, or process equipment will find the pre-installed assemblies especially relevant. The extra-duty sliders support heavy rackmount modules and chassis that standard lighter-duty slides cannot safely handle.
