  • Ammonia Gas Detection- system codes and design

    CO2 detection is required instead of ammonia detection in refrigerated and process areas. Detection system design and output functions are similar with the difference being the CO2 sensor selected, warning setpoints at 0.5% (OSHA 8 hour TWA) and alarm setpoints at 1.0%. One controller can support a combination of ammonia and CO2 sensors.
