Easy-Ripe® Ethylene Generator

easy-ripe-evoEasy-Ripe® Ethylene Generators are the easiest and safest method for ripeners:

  • Simply place in the ripening room in a convenient location
  • Plug into a properly grounded electrical outlet
  • Select conversion rate
  • Pour one or two quarts of Ethy-Gen® II Ripening Concentrate
  • Ethylene production begins in just a few minutes!

The easiest and safest* way to apply ethylene!

The Easy-Ripe® Generator is available for lease (North America and UK) or purchase (worldwide); contact us for details.

For Operating Instructions in various languages, please see our Support Page: Operating Instructions

The Easy-Ripe® Generator provides non-pressurized and safe* ethylene on a continuous basis for uniform ripening & degreening.

Ethylene output is adjustable for multiple room sizes, which means the Easy-Ripe® can adapt to any ethylene PPM requirements. For larger rooms, additional units easily achieve proper ethylene levels.


Proper Operation Indicator Light: With intelligent microprocessor technology, critical production processes of the generator are monitored. A highly visible light on the top of the generator constantly shows the operation status of the unit:

green light makes it clearly evident of ethylene production

A red light will provide an alert in the rare occurrence of a malfunction.

Compliance with International Testing Stadards:
Available with UL® and TÜV (TÜV Product Service of Germany) and CE Conformity to 73/23/CEE and 89/336/EEC.


Additional details:

  • Can work with a computerized ripening room control system.
  • Available in a wall-mounted version.
  • Large 2.7 quart reservoir (2.56 liters).

Conversion Rate Settings of Ethy-Gen® II and approximate room size:
#1: 1 Quart every 48 hours; 1,500 to 2,499 ft3 (43 – 70 m3)
#2: 1 Quart every 36 hours; 2,499 to 4,999 ft3 (71 – 141 m3)
#3: 1 Quart every 24 hours; 5,000 to 7,499 ft3 (142 – 212 m3)
#4: 1 Quart every 12 hours; 7,500 to 12,000 ft3 (213 – 340 m3)We have found these setting to be applicable for most rooms and provide sufficient ethylene (150 – 300 ppm) to initiate the ripening process in bananas, tomatoes and other fruits (except citrus, which requires less than 10 ppm; for this, use our Citrus Generator). However, some ripeners prefer to take ethylene readings with an Air Sampling Kit and select the setting that produces the ethylene level desired. As always, please contact us if we can be of service.

Note that for rooms larger than 12,000 ft3 (340 m3), additional generators can be used, if needed, to achieve the proper ethylene level. It may be possible to use just one generator for a room that is larger than 12,000 ft3; it depends upon how tight the room is. We have some customers that are able to use just one generator in rooms that are 20,000 ft3 (566 m3) and achieve 150 ppm of ethylene.
