BV Type-Approved GAC-M20 Continuous-Sampling Gas Detection Cabinet with 8 Independent Channels and Pump-Assisted Sampling

The GAC-M20 Continuous-Sampling Gas Detection Cabinet is designed for high-risk marine areas such as LNG cargo tanks and fuel tanks. Each monitoring point has its own dedicated sensor for uninterrupted gas concentration monitoring, with data uploaded directly to the central gas alarm control cabinet.

The cabinet supports multi-channel continuous active sampling, with filters and shut-off ball valves at the front end, flame arresters on both inlet and outlet, and built-in leak detection and alarming. In the event of an internal pipeline leak, the cabinet immediately triggers an alarm, cuts off the pump power and purges the internal gas with an external gas source, protecting the vessel and its crew.

• Dedicated sensor per point - eliminates cross-talk and improves reliability
• Pump-assisted sampling - actively draws gas from the monitored space
• Multi-channel continuous active sampling - 8 independent sampling channels
• Front-end filters and shut-off ball valves - easy maintenance and safe isolation
• Flame arresters on inlet and outlet - intrinsically safe design
• Built-in leak detection and alarm - self-protection for the pipeline
• External gas purging - automatic purge after a leak
• Direct connection to the central cabinet - seamless system integration

• LNG cargo tanks
• LNG fuel tanks
• Other high-risk enclosed spaces onboard requiring continuous gas monitoring

Equipment must pass classification society type approval before being installed on marine and offshore vessels. The GAC-M20 has received BV type approval as part of the gas detection and alarm system, meaning its design, testing and production have all been validated by an international authority and it can be used on classed vessels worldwide.

In the marine and offshore sector, gas detection equipment can only be installed onboard after passing type approval by an internationally recognized classification society. This product holds a Type Approval Certificate issued by Bureau Veritas (BV), confirming that its design, manufacture and performance fully meet the classification requirements for international voyages and offshore installations.
