The Problem
A food processing plant needed a CIP loop leak located between sanitation cycles. Plant operated 20 hrs/day, 6 days/week.
Detection Method
Tracer gas injection into the CIP loop during the 4-hour sanitation window. Detected a pinhole leak at a welded fitting in 90 minutes.
Results
Repaired during next scheduled sanitation cycle — no additional downtime. HACCP documentation updated. Annual CIP loop tracer gas surveys now scheduled.
