Qatar Refinery Junction Box Deployment

Background

A downstream refinery in Qatar with 35,000 barrels per day capacity needed to replace aging junction boxes across its process units. The original equipment was reaching end-of-life and the refinery wanted to consolidate on a single supplier with ATEX/IECEx dual certification to simplify spare parts management.

Challenge

• •6-week total shutdown window — no margin for delay
• •220 junction boxes across 4 process units
• •Mix of Ex e IIC (increased safety) and Ex d IIC (flameproof) requirements
• •316L stainless steel required for coastal salt-spray environment
• •Documentation package required for Qatar Civil Aviation / regulatory audit

Our Solution

• ✓Free application assessment: confirmed Zone 1, Gas Group IIC, T4 temperature class
• ✓Standard 316L Ex e IIC junction boxes in 8 standard sizes (matched to existing cable entries)
