Semi-welded plate heat exchanger released ammonia at indoor ice surface facility’s refrigeration plant

Location: Peace River Region

Regulated industry sector: Boilers, PV & refrigeration - Refrigeration system

Incident overview

Brine samples taken from an indoor ice surface facility’s refrigeration plant contained ammonia. A second set of samples confirmed even higher levels of ammonia, which led to the discovery that the internal pressure boundary of a semi-welded plate heat exchanger was leaking.
