F-901R AccuRipe

Complete Ripening Room Control Means Complete Management of Ripening Rooms

F-901R AccuRipe for monitoring and control of cold storage rooms.

The beating heart of the F-901R AccuRipe combines the power of advanced sensor technology with the intuition and innovation of our Ethylene Generators, resulting in reliable, real-time information about your ripening or degreening facility.

Our F-901R AccuRipe system places ripening control in your hands by utilizing sensors that detect ethylene, temperature, relative humidity (RH%) and carbon dioxide (CO2). This system offers comprehensive knowledge of your ripening environment and provides complete control over every aspect.

With the touch screen mounted in or out of the room, enter a setpoint, then the controller will automatically regulate ethylene production of our generators. When a door is opened, the controller sees it and adjusts the ethylene level. When the setpoint is reached, the controller sees it and slows ethylene production to maintain the setpoint.

F-901R AccuRipe Benefits: 

  • Know your ethylene levels anytime from anywhere
  • Have full control of ethylene levels by setpoint and generator modulation
  • Maintain archive of ethylene, RH% and temperature levels (and other conditions with optional sensors)
  • Be alerted to problems by e-mail, text message, or audible alarm



High Range Ethylene Sensor

The system features a High Range Ethylene Sensor with a setpoint range from 10-1000 ppm. The sensor is easy to calibrate and replace when needed. An onboard KMnO4 Zero Scrubber will automatically zero the sensor for even better accuracy.

With factory customization, any of our ethylene generators can be adapted to work with the F-901R AccuRipe system. Simply enter an ethylene set-point and the ethylene sensor and generator will work together to automatically regulate ethylene production.

Remote Access Via Network

Control ethylene output remotely via a network connection. The F-901R AccuRipe allows users to view ripening room ethylene, relative humidity, and temperature all at the same time. As an added option, CO2 and O2 levels can be monitored.

Track ethylene progress and adjust output settings in real time with this feature. With intelligent microprocessor technology, critical processes of the generator are monitored. A continuous indication of operation status is provided, making it clearly evident of ethylene production.
