Supermarkets

Recent changes in interpretations of building codes have forced supermarkets to re-evaluate the capabilities and coverage of their refrigerant detection systems.

In many parts of the U.S., local building and fire code officials are interpreting typical walk-in coolers in supermarkets as "confined spaces", creating the need for refrigerant-specific sensing. Manning Systems AirScan™ iR will not false trip around fruits, vegetables, dairy products, fish, etc. and requires little maintenance over an extended sensor life.

Sensors are monitored by a central alarm panel, either the single channel GM-1 or multi-channel GM-10 or GM-4. If ppm and alarm status indication are needed at the entrance to a walk-in cooler or other confined space, the GM-JR is ideal for this purpose.

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.

A diffusion-type system has great advantages in cold or wet environments. There is no danger of pumping water back to a central analyzer or the possibility of diluting the ammonia sample, as would be typical of a sample draw system installed in a wet environment. Ice formation in the sample draw tubing can block the return lines and totally disable the system.
