Case Study

Fielding Environmental

THE CLIENT

Fielding Environmental is a cleantech company specializing in the recycling of waste solvents, glycols and refrigerants.

THE SITUATION

Fielding Environmental used nitrogen gas as part of their process in the plant to purge critical lines in the facility. Their existing nitrogen generator had no backup unit so downtime was a possibility in the event of unplanned shutdown or maintenance. When Fielding’s existing generator had a critical failure, they first called their existing service provider, but were told that the nitrogen technician was on vacation and would not be onsite for 3-4 days. They immediately turned to CRU AIR + GAS, and we had our nitrogen specialist on site in less than 1 hr.

THE SITE VISIT AND ASSESSMENT

CRU AIR + GAS’s nitrogen specialist determined that the carbon bed in the existing nitrogen generator had failed. This is a critical failure on the unit and would need to be replaced at a cost of more than 60% of the unit cost. CRU AIR + GAS was able to find a BOGE nitrogen generator in stock that could be delivered and installed within a week. The unit would include full MODBUS communication capabilities and so Fielding Environmental approved the project immediately.

THE RETROFIT

Fielding Environmental’s RETROFIT system consisted of the following equipment:

  • BOGE N42P Nitrogen Generator w/MODBUS interface for HMI communication
  • BOGE Activated Carbon Filter
  • 120 gallon buffer tank

THE RESULTS

Fielding Environmental was able to integrate their new BOGE nitrogen generator into their HMI system and have complete visibility on nitrogen production and purity. Their existing generator became an emergency backup to be used during maintenance of the new generator.
