Applications & Installation
This explosion-proof gas monitoring system supports multiple installation types including wall-mounted, tube type, scaffolding type, and ceiling type configurations. The system is ideal for:
Chemical plants and petroleum refineries
Gas transmission and distribution facilities
Industrial manufacturing and metallurgical operations
Commercial buildings with gas-powered systems
Residential complexes with shared gas infrastructure
Safety Features: Multiple event delay confirmation prevents false alarms, while audio-visual alerts ensure immediate response to genuine threats. The system automatically activates safety devices like exhaust fans and solenoid valves when gas concentrations exceed preset limits.
