Store Control: Grain Fan Assist

Store Control, from Evans and Pearce, takes a novel look at Differential Temperature Control for grain storage.

The Store Control system turns standard grain ventilation fans, into smart fans that can automate the cooling of your crops without the need for costly electrical installation and annual data hosting charges.

Standard grain ventilation fans can be fitted with the Grain Fan Assist unit which will turn them into a smart fan, capable of running the store for you.  Grain temperature is monitored via a 2m long spear and the ambient air temperature is monitored via a sensor on the Store Control box itself.

Differential temperature is easily set and then the fan will switch itself on every time the air is cold enough to effectively cool the crop.

If the grain store has additional ventilation fans to introduce clean air into the building, the Extraction Fan Assist unit will wirelessly turn these on as well.  An additional receiver unit will detect when any of the grain ventilation fans is in operation and will ensure the building extraction fans are working.


·         Simplicity.

·         Can be fitted to new or existing fans.

·         Minimal, if any, input from an electrical contractor to automate your store.

·         Wireless; so only power cable to fan, no additional cabling in store.

·         Each fan reacts to the condition of grain immediately around it, so no additional costs for store zoning.

·         Fan will display crop temperature, so no need for additional sampling.

·         Fan running hours recorded, so electricity usage easily calculated.

·         Easy store automation costing, no hidden charges or ongoing license fees.

·         Send fans back to us and we will return to you a smart fan ready to run your store.
