Tips: Where should fixed NOX gas detectors be installed?
Fixed NOX gas detectors should be installed in locations where nitrogen oxide gases are likely to accumulate, ensuring optimal safety and monitoring efficiency. Key areas include:
- Near Sources of Emission: Position detectors close to potential Nitrogen Oxides emission sources such as boilers, furnaces, engines, and industrial processes that involve combustion.
- Ventilation Systems: Install detectors in HVAC systems and exhaust ducts to monitor and control indoor air quality.
- Low-Lying Areas: Since NOX gases can be heavier than air, placing detectors at lower levels can help in the early detection of leaks.
- Enclosed Spaces: Areas like basements, tunnels, or enclosed parking garages where Nitrogen Oxides can accumulate due to poor ventilation should have detectors.
- Entry and Exit Points: Place detectors near doors, windows, and other openings to monitor NOX entering or leaving confined spaces.
Regular maintenance and calibration are essential to ensure accurate detection and response to NOX gas levels. Proper installation in these strategic locations enhances safety and compliance with environmental regulations.
