Equipment Rooms

If you have very limited funds for ammonia leak detection, engine room monitoring is an excellent first step toward protecting your plant from the danger and expense of ammonia leaks.

For ammonia monitoring from 15 to 1,000 ppm (parts per million), the EC-F9-NH₃ electrochemical sensor operates without false trips. Ranges include 0-100, 0-250, 0-500 ppm, and 0-1,000 ppm ammonia.

For high level monitoring (up to 2% [20,000 ppm]), either the SB-NH₃ semi-conductor sensor or IR-NH₃ infrared sensor will work well, again, depending on the environment and ventilation. Because it is specifc to NH₃, the IR-NH₃ ammonia sensor is the best choice for engine room shutdown.

As plants are required to meet tighter regulations and the consequences of false trips increase in severity, the combination of EC-F9-NH₃ and IR-NH₃ gives "no false trip" performance from 15/20 ppm through 20,000 ppm (2%). These are integral components of the Manning Primary Safety System (MPSS).

The VL Vent Line Sensor monitors ammonia or refrigerants in relief lines to give an early warning of refrigerant releases. Please discuss the details of vent line sensor placement with Manning's applications specialists.
