The new Cropscan 16 mc4 will operate with 1 to 16 crop sensors, 1 ambient sensor, 1 air mix sensor and optional RH sensor.
Air mix control to mix ambient air with store air to achieve desired cooling air temperature, adjustable, with built in safety cutout at 1.5C below air mix set point.
Shut off interval to prevent immediate restart, adjustable up to 5 hours.
Refrigerated cooling controls give priority to ambient air cooling.
LED map show actual state of control functions with arrow chain starting with “cooling required” then leading to “cooling on” or “refrigeration on” according to ambient temperatures and programme selected.

Cropscan 16mc4 Software Enhancements – March 2013
Two useful extra/improved features have now been released in a Software Upgrade to our popular Cropscan 16mc4 controller.
Previously this provided a basic fan / louvre control without the ability to “Air Mix”. This feature now has full Air Mix control which will provide the ability to warm a crop in a very controlled manner thereby minimising the danger of condensation etc. due to a large temperature differential.
A totally new control feature is DRYING. This became very relevant during the unprecedented wet harvest in 2012 which affected many growers. This allows the user to enter a safe “Drying Band” temperature around the current crop temperature. If the ambient temperature remains within this band the fans will run with the louvres fully open to dry the crop. In addition if an Ambient RH sensor is fitted, a high RH limit can be entered which will stop drying if it is considered too wet outside. If the user wants the fans to continue running even when outside conditions are unsuitable they can be set to run in Manual and then only the louvres will close leaving the fans running in recirculation.
All new Cropscan 16mc4 controllers will include these new features. Existing users can have their controllers easily upgraded if desired.
