Auto-Ripe® Generator

Auto Ripe® 2021 Ethylene Generator

Reliable, effective and easy to use, our Auto Ripe® Generators hold enough Ethy-Gen® II Ripening Concentrate to perform up to four ripening cycles, in a one or two load ripening room.

Auto Ripe® 2021 Ethylene GeneratorHow it Works:

  • Just pour one to four liters of Ethy-Gen® II and ethylene production quickly begins.
  • 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 Auto-Ripe® can adapt to any ethylene PPM requirements. For larger rooms, additional units easily achieve proper ethylene levels.
  • Low-level light indicates when Ethy-Gen II reservoir reaches levels of 250 mL or below



Slim Design & Wall-Mounting Ability

Auto Ripe Back

Four keyhole slots are on the backside of the Auto-Ripe® Generator 2021 for quick and easy wall-mounting. For your convenience, we’ve provided a printable wall template for installation here.

At only 14.2 cm depth, the Auto-Ripe® is an ideal solution for narrow ripening rooms. Ease your mind as forklifts and other mechanical equipment enter and exit ripening rooms with this slim design.




Operation Light

Proper Operation & Low Level Indicator Light

With intelligent microprocessor technology, critical processes of the generator are monitored.

Continuous indication of operation status is provided, making it clearly evident of ethylene production.

Two LED lights turn on when the reservoir of Ethy-Gen® II reaches low levels of 250 mL or less.



Compliance with International Testing Standards

This innovative generator and Ethy-Gen® II Ripening Concentrate is the only one of its kind to be certified by TÜV SÜV America.

Additional details:

  • Can work with a computerized ripening room control system
  • Wall-mount is standard
  • Large 4-litre reservoir
  • 2.5 and 1-litre reservoir tank size also available
  • Minimum room size for an Auto-Ripe® is 57 m3

Conversion Rate Settings and approximate room size:
# 1: 1 litre of Ethy-Gen® II every 48 hours; 57 – 70 m³
# 2: 1 litre of Ethy-Gen® II every 36 hours; 71 – 141 m³
# 3: 1 litre of Ethy-Gen® II every 24 hours; 142 – 212 m³
# 4: 1 litre of Ethy-Gen® II every 12 hours; 213 – 340 m³

Note that it may be possible to use just one generator for a room that is larger than LxWxH, 340 m³; it depends upon how tight the room is. 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 340 m³, additional generators can be used to achieve the proper ethylene level.
