PRI provides single source responsibility for the engineering design, manufacturing, testing and field implementation of the system. All systems are completely assembled in our shop where Factory Acceptance Testing (FAT) takes place. This allows the client to see the system operate and challenge the system with any unique operational needs that will occur at the facility.


When it is time to start the unit in the field, a PRI Engineer will verify the installation, check the system integrity, validate the operational modes, run a series of checks, and provide training for the facility's maintenance crew and operators.
