Why You Should Be Using The Centralized Ripening System

Across the globe, customers utilize multiple ripening rooms to efficiently ripen produce. Thanks to our Centralized Ripening System®, all your ripening rooms can have continuous ethylene production from one central supply of Ethy-Gen II Ripening Concentrate. Our easy and convenient ethylene source offers peace of mind with complete confidence in your equipment with no fear of explosions and makes your ripening operation safer.



IDENTIFIABLE ETHYLENE VERIFICATION. As a visible liquid, Ethy-Gen® II Ripening Concentrate is easy to inventory and reorder as needed. Rather than weigh cylinders or guess amounts, our product does the work for you.

LOW MAINTENANCE. With a system that lasts up to five times longer than competitors, we save you valuable time and money. Quick disconnect fittings and palletized containers of Ethy-Gen® II make swapping out containers a pain-free experience. A simple pallet jack is all you need to move containers into place with the CRS® Pumping System. No longer will you need to deal with awkward, bulky and dangerous ethylene cylinders.

GET COMPLETE CONTROL. Experience a control of your ethylene systems like you’ve never experienced before. Rather than transmit ethylene by pipe into each individual room, our system makes ethylene right inside the ripening room. It’s as easy as flipping a switch to turn ethylene on and off in each room. Make adjustments to levels by turning a single knob. Our system takes away the worry of ethylene dissipating in pipes or being wasted in any way.

CONVENIENT LOW FLOW SENSOR. All of the generators produced by Catalytic Generators provide indication of correct operation. The CRS® Pumping Station monitors proper flow of Ethy-Gen® II, additionally. For your convenience, your station will light up red once you’ve run out. Keep your supply current at all times with this system!


Our safe, easy, and convenient ethylene source is one you can trust. To ensure your CRS® is set up and integrated properly, our knowledgeable staff can install the system for you. The installation is typically completed in one day; however, larger facilities may require more time. We begin the process with an analysis of each room to assess your needs. After this has been done, we then set up the generators’ ethylene production to match your required parts per million (ppm) level.
