Catalytic Generators introduce Central Ripening System

From a central supply of Ethy-Gen® II Ripening Concentrate, the CRS - Centralized Ripening System® will serve from just a few to more than 40 ripening rooms with continuous ethylene production in order to initiate the controlled, natural ripening and degreening process of fruits.


Latest Generator Upgrade available

We continue to look for ways to improve our products and make ripening even easier and more efficient. One of our latest improvements is the Proper Operation Indicator Light. Making the ripening job even easier, an all-new control board powers this indicator light and monitors critical processes of the generator. A bright green light indicates that these processes are running correctly and ethylene production should be optimal.
