The On-Board IS-2000V is a high-capacity helium compressor for Edwards CTI-Cryogenics On-Board IS cryopump systems. It uses variable-speed operation and adaptable helium delivery, supports multiple-pump installations, and is offered in distinct low- and high-voltage configurations. Edwards acquired the CTI-Cryogenics product line from Brooks Automation in 2019, accounting for both Brooks and Edwards identification on legitimate units and documentation
Configurations vary. Verify the exact unit before choosing a replacement.
Edwards documents more than 20% lower energy consumption and approximately 40% lower facility cooling-water thermal load compared with IS-1000 installations
Replacement
System-capacity relationship
Designed as a single-compressor alternative to two On-Board IS-1000 compressors
Compliance
Environmental compliance
RoHS compliant; designed in alignment with the energy-reduction objectives of SEMI S23
Configuration Boundary
IS-2000V identifies the compressor model but does not uniquely select its electrical and customer-option configuration.

Interpretation
Voltage class
Low voltage or high voltage
Use the complete manufacturer part number or physical label before assigning a configured-unit voltage.
Pressure indication
PSI or KPA variants appear in the Edwards catalog
The base model does not establish the installed gauge units.
Emergency-off arrangement
Catalog variants include PT EMO, INT EMO, and without-EMO descriptions
The reviewed documents do not fully define every abbreviation; do not expand or assign these options without the applicable manual or configured part number.
Configured-unit identity
Separate Edwards part numbers exist for the available combinations
IS-2000V alone must not be treated as one fixed electrical or controls configuration.

Later-Generation Upgrade Context
Atlas Copco Group identifies the Edwards IS-1800V as the latest generation of the On-Board IS compressor series. This establishes a later-generation upgrade path, not universal drop-in compatibility.
Later-generation modelEdwards IS-1800V
Launch year2022
Documented application exampleFor a typical ion-implant installation with three On-Board IS 320FX cryopumps, Atlas Copco reports approximately 20% lower energy use and approximately 40% lower cooling-water use when upgrading from IS-2000V to IS-1800V.
Compatibility boundaryConfirm cryopump mix, controls, electrical service, helium connections, facility interfaces, and the applicable Edwards upgrade procedure before substitution.
