Stonegate Instruments (UK) has developed a new improved Gas Detection System for the air conditioning and refrigeration industry, which is already proving to be a popular addition to its product range.
The system has been carefully designed to detect a wide variety of popular refrigerants including CFCs, HCFCs and HFCs. It can accommodate up to 24 remote refrigerant sensors and uses a compact central monitor unit with flexible wiring for easy installation. In addition, both audible and visual alerts for alarm conditions and sensors can be included.
The sensors are arranged in three zones of eight channels with four relay outputs for signalling an alarm, one for each zone. These relay outputs de-energise when any sensor in the corresponding zone signals an alarm and a main alarm relay will also de-energise if any sensor in any zone signals an alarm.
