Simple in-store drying control
Drying grain using ambient air can be quicker and more likely to succeed using a Thermo-Humidistat fan controller. Knowing the grain moisture and setting appropriate humidity and temperature limits on the controller ensures that ventilation fans only blow or suck air suitable for drying into the grain. Sensors monitor ambient relative humidity and temperature and automatically start the fans if conditions fall below the pre-set limits.
The Thermo-Humidistat Fan Controller displays ambient temperature and relative humidity using built-in sensors connected to the unit.
Measuring grain moisture and using pre-set humidity limits on the controller ensures that ventilation fans do not draw damp air into the grain and are only used to dry the grain. Remember that ambient air cannot be guaranteed to dry grain and the speed of drying will vary according to ambient conditions.
Our Thermo-Humidistat Fan Controller can be made as a static or a portable unit. The Portable Thermo-Humidistat Controller solves the problem of sharing ventilating fans between crop stores on the same site or different sites, with just one controller. The portable controller can be easily moved between stores when the fans are re-located.
Controls any quantity of single or 3 phase fans, including large tunnel drying fans and StoreVent building air extraction fans. An automatic fan starter is required for each fan being controlled.
Portable Thermo-Humidistat Controller
Controls automatically up to 5 single phase or 3 phase portable fans. It has built-in starters for each fan being controlled and can be repositioned when fans are moved between ducts and stores. It is supplied with all plugs and sockets to connect the fans to the controller and the controller to the power supply and just requires a suitable 32 Amp power supply, so extensive electrical installation work is avoided.
