Refrigeration Systems

Ammonia, as well as many other refrigerants, can be monitored by Manning Systems gas sensors. The list of refrigerants includes halocarbons, R-22, R-134a, R-404a, R-507, etc. Please call regarding any other refrigerant, as this is not a complete list.

The EC-F9-NH₃ electrochemical sensor detects ammonia leaks in almost any environment without nuisance trips and, with proper placement, the sensor exhibits long cell life. Cells are easy to replace and inexpensive.

If specific levels of halocarbons must be monitored or interference gases are present, the AirScan™ iR is a rugged infrared sensor with no moving parts (i.e., no pumps or filters to replace). It will operate for several years with minimal maintenance.

Manning Systems enclosures with optional ATMOS equipped^® technology (Adaptive Temperature and Moisture Optimizing System) feature the first enviro-adaptive technology available for gas sensors. Manning Systems electrochemical and infrared gas sensors with ATMOS equipped^® technology can automatically adapt to environments from -50°F to 100% humidity and washdown conditions, assuring industry leading performance in the harshest environments.

When carbon dioxide is used in a refrigeration system, the AirScan™ iCO₂ infrared sensor will operate in all refrigerated areas when equipped with the ATMOS enviro-adaptive technology option.

The VL Vent Line Sensor monitors ammonia or refrigerants in relief lines to give an early warning of refrigerant releases. It can be used with either reliefs piped to atmosphere or a water dump tank, but please discuss the details of all vent line leak detection applications with Manning Systems.
