8116231G002R is a Brooks Automation / CTI-Cryogenics configured On-Board 10 cryopump assembly identifier found in stored Sonisys auction records. The On-Board 10 family is a cryogenic high-vacuum pump platform with integrated On-Board controls, FastRegen capability, roughing and purge hardware, temperature sensing, setpoint relay support, and remote communication options. Stored auction records also include 8112578G001 in the title; that number is retained as observed listing context and should not be treated as a standalone exact alias for this full pump assembly without label verification
Configurations vary. Verify the exact unit before choosing a replacement.
High-vacuum pumping by cryocondensing and cryosorbing gases on cold arrays driven by a helium refrigeration circuit
Array function
The 80K array condenses water and hydrocarbon vapors; the 15K array condenses nitrogen, oxygen, and argon while charcoal traps helium, hydrogen, and neon
Controls
Integrated control platform
On-Board cryopumps use integrated microprocessor control with hardware keypad/display options, diagnostics, regeneration control, and remote operation options
Remote communication context
Family documentation describes RS-232 operation and BITBUS networking through an On-Board Network Terminal for process-tool integration
Setpoint relays
Family documentation describes two setpoint relays rated 1 amp at 25 V AC/DC with normally-open and normally-closed contacts
Connections
Rough pump connection
NW 25 ISO KF
Air supply connection context
On-Board component identification diagrams show air supply at 60 to 80 psig through a 1/8 NPT connection
Purge gas connection context
Family documentation describes purge gas supply at either 10 to 25 psig or 40 to 80 psig depending on purge-valve labeling

Installation orientation
Family installation instructions state the On-Board cryopump may be installed in any orientation without affecting performance
Configuration
Configured-unit rule
Flange, controls, keypad/display position, compressor compatibility, valves, attached modules, rebuild state, and OEM tool integration must be verified from the physical label and installed system
Observed variants
