Cold Rooms
DST G54A / DST G54C / DST G55A is an A2L gas sensor range for refrigerant leak detection and gas monitoring in refrigeration-related applications. In cold room systems, A2L gas sensors belong to the wider safety and monitoring layer of the installation. They are relevant where refrigerant monitoring is needed to help detect gas buildup, support warning or alarm handling, and improve operational safety. The internal cold room product list explicitly includes DST G55A, DST G54A, and DST G54C under gas detectors, which supports their relevance in the cold room portfolio.
