Banana and Produce Rooms

Banana Rooms and Produce Coolers are the main reasons that Manning Systems pioneered the use of electrochemical sensors for detecting ammonia in these difficult areas. Many years and thousands of sensors later, electrochemical technology is still the best answer for low ppm "no-false-trip" sensing in banana storage and produce coolers. The EC-F9-NH₃ electrochemical sensor is specific to ammonia, i.e., will not trip on ethylene or other gases, and operates for several years between cell replacement with minimal maintenance.

The IR-NH₃ infrared sensor will sense only ammonia and can be relied on for accurate, repeatable information when used for high level ammonia sensing or electrical shutdown.

If halocarbon refrigerants are used, the AirScan™ iR infrared refrigerant sensor won't false trip when exposed to the mixture of gases typically found in either of these applications.

A diffusion-type system has many advantages in cold or wet environments of food processing and storage. With the information transmitted by wire continuously in real time, there is no danger of pumping water back to a central analyzer or the possibility of diluting the gas 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.
