SOME INNOVATIONS IN THE OPERATION OF CA ROOMS 



R,M. Smock 

 Cornell University 



Dr. P. Marcellin, a French research worker, has developed 

 two yery ingenious units for maintaining the atmospheres in CA 

 storages. We have tested both of these units to see if they had 

 any application for American conditions.

An innovation that comes from Holland is the "Oxy-drain" unit 

 This unit is a nitrogen generator that employs ammonia as the gas 

 instead of propane. The ammonia is "cracked" in the machine and 

 the hydrogen produced is burned. As a result one gets nitrogen 

 produced with yery low oxygen levels. This is similar to Tectrol 

 (no longer produced) or Arcat units except that no carbon dioxide 

 results from combustion. As a result no scrubber is needed to
