Product Description
GAC-M20 Continuous-Sampling Gas Detection Cabinet
8-Channel Active Sampling System for LNG Cargo Tanks and Fuel Tanks
Product Overview
The GAC-M20 Continuous-Sampling Gas Detection Cabinet is engineered for high-risk shipboard environments including LNG cargo tanks and fuel tanks. Each monitoring point features an independent sensor, enabling uninterrupted gas concentration monitoring with data transmitted directly to the central gas alarm control cabinet.
Safety Protection System
This cabinet supports 8 channels of continuous active sampling with front-end filters and shut-off ball valves. Flame arrestors are installed at both inlet and outlet points, and an internal gas detection alarm provides comprehensive protection. In case of internal pipeline leakage, the system generates an alarm signal, cuts off the internal pump power supply, and purges the cabinet's internal gas using an external gas source - ensuring complete safety for both vessel and crew.
Key Features
  • Independent sensor per monitoring point - eliminates cross-talk and increases reliability
  • Pump-suction sampling - actively draws gas from monitored spaces
  • Multi-channel continuous active sampling - 8 independent sampling channels
  • Front-end filters and shut-off ball valves - maintenance-friendly with safe isolation
  • Flame arrestors at inlet and outlet - intrinsic safety design
  • Built-in leakage gas detection alarm - internal pipeline self-protection
  • External gas-source replacement - automatic purge after leak events
  • Direct data feed to central control cabinet - seamless system integration
Application Scenarios
LNG cargo tanks, LNG fuel tanks, and other high-risk confined spaces on board where continuous gas monitoring is required.
