CPC-DX Skid Project (Dual Transfer)

Functional Description

This Redundant CPC skid includes two CPC-II units configured in a master/slave configuration, where the master unit controls output pressure, and the slave unit tracks master unit operation, and bumplessly takes control of output pressure should there be a failure with the master unit. Optionally users can switch between converters to verify unit operation, and replace either converter “on-line”, should there be a need.

CPC-DX Skid Features:

• Single Assembled Skid
• Automatic Transfer Logic
  • No External logic required
• On-line Repairable
• Fast transfer times
  • Minimal system disturbance
