Locating air conditioning equipment in a roof top plant room may alleviate the threat to health and safety as potential refrigerant leaks are vented into the atmosphere. However, a leaking system still has cost implications because less gas equals inefficient operation.

Installing a fixed point refrigerant gas leak detection system will monitor for potential leaks continuously and can give audible/visual alarm as well as the ability to connect to a BMS if available.

For external chillers, placing a sensor within the compressor compartment is recommended. IP rated sensor housings are also available if required.
