The GasVac 306 system is designed to monitor gas levels from a number of sample-points, targeted at situations where the positioning of conventional gas sensors may not be practical. This may be due to equipment security, cable routing, access for detector head installation/maintenance, harsh environment or a cost effective means of monitoring designated hazardous areas, typically - tunnels, marine applications,underground/high level voids, process control, landfill, multi storey car parks, brewing, horticulture,superstore multi refridgeration units.
Gas samples are sequentially extracted for a timed period by a central control unit via fixed sample lines.A high rate sample is taken by the main pump during which a reduced rate sample is passed across the sensor device. The central unit provides gas level readouts with two alarm trip points per line, providing arange of signal outputs for annunciator and control functions.
