Typical modern split AC systems use HCFC gases, such as R407C, R410A. Should there be a failure of any part of the system, there is a risk of refrigerant gas leaking into the atmosphere. Leaking systems are inefficient and more expensive to operate but also pose a health risk to occupants as refrigerant gas depletes oxygen and can in some cases cause suffocation.

Installing a fixed point refrigerant gas leak detection system will monitor for potential leaks continuously and will give local audible/visual alarms.

The AT-G-SENSE is an unobtrusive stand-alone sensor that is typically mounted at low level in the room or in the ceiling void adjacent to the fan coil unit.

Sensors can be directly linked to a BMS or monitored by a central alarm panel (AT-GSC-16).
