Centralized Ethylene Supply for Tobacco Curing

Centralized Ethylene Supply for Tobacco Curing

CRS Generators and Ethy-Gen® II Concentrate are ordered directly from Catalytic Generators, LLC, and then shipped to you, using freight lines and UPS.

Our CRS is the best system available for accelerating the tobacco curing process, and it’s safe, effective and easy to use. It will supply any number of barns with a constant supply of Ethy-Gen® II Ripening Concentrate, which is converted to ethylene by our CRS Generators, conveniently positioned in each barn.

1. How It Works
Our custom-designed low-flow pumping station provides a continuous supply of Ethy-Gen® II Ripening Concentrate to the CRS Generators through a specially designed loop of industrial grade tubing. When you’re ready for ethylene application, it’s as simple as turning on the CRS Generator.

2. Easy To Use
Even when you’re not actively ripening, the CRS is easy to maintain. Our packaging allows for inspection of the product received, and makes it easy to check inventory. We’ve removed the guesswork from ethylene, meaning that you’ll no longer have to weigh your supply, and will never again inconveniently run out.

Thanks to the large supply of concentrate available to the CRS, refills and swapping out containers are a thing of the past. Reduce the time and manpower spent babysitting and streamline your ripening process with the CRS.

3. InstallationCRM
Most barns are laid out in a similar fashion, adaptable to the CRS design. We install all necessary equipment for you, and the process usually takes 1 or 2 days.

Container installation is simple, thanks to our “Quick-Disconnect” fittings and our Pump Control Station constantly monitors for proper flow of Ethy-Gen® II. In the event of an empty Ethy-Gen® II container or any other hindrance, the Pump Control Station notifies personnel immediately.

The CRS is installed with a Control Station that includes the following features:

Leak Detection:
Our high-quality electronic flow detector is sensitive to changes in the amount and flow of Ethy-Gen® II Ripening Concentrate in the return line of the CRS.

In the event of a leak, the Control Station will cut all power to the CRS pump, stopping the flow of Ethy-Gen® II. To signify a problem, the Control Station will flip on a bright red indicator light. Other options, such as an audible alarm or phone notification, are available.

Our Control Station provides a quick and simple method of switch the CRS on or off. Should the flow detector sense a low flow of Ethy-Gen® II Concentrate, the device will cease and the red indicator light will turn on. This feature gives personnel a notice that the containers need to be changed, extending the life of the pump.

In the event of a power outage, the Control Station is quipped with a time delay, which will override the flow detector and allow the pump to prime.

crspumpCRS – Centralized Ripening System® Generator

The CRS Generator is safe, effective and adjustable to any ethylene requirement. Let us improve the quality and efficiency of your ripening process by providing continuous, consistent ethylene production.

The CRS Generator is mounted on the wall, and with it’s narrow design, does not take up much space in the furnace room of the barn.

Like our Tobacco Curing Generator, the CRS uses a flexible hose to direct the ethylene output through the furnace floor and into the airflow.

This generator provides safe and effective ethylene levels; however, ethylene is explosive at 27,000 ppm, so only use our equipment in spaces that are 1600 ft3 (45m3) or larger.
