A new system that remotely monitors and automates grain store ventilation systems has been launched by Evans and Pearce.
CropCool Wireless autonomously controls fans and probes to maintain in-store grain in optimum condition, using ambient air when it is at its coolest and driest to maximize cooling effectiveness and minimise energy consumption.
HGCA recommends 6 cubic feet per minute (cfm) of airflow per tonne of stored crop. Even with the correct levels of air it is equally as important to ensure ventilation is well managed. Differential temperature control is key to this and with the new technology available,
For effective cooling air temperatures need to be 4-6°C lower than the crop. CropCool wireless monitors grain temperature, compares it to ambient air and then decides when the fans should be turned on and off. This will invariably be between 2am and 6am during early autumn; a time of day when most farmers are not in the grain store but when rapid crop cooling can take place. HGCA calculates that in some situations differential temperature control can save up to 40% in electricity costs over a manually controlled system.
CropCool Wireless can evolve from a basic monitoring package to a full-blown store control and crop data logging system over time. The wireless temperature probes feed information back to the controller which then coordinates ventilation fans according to temperature and/or humidity. The farmer can build up crop storage trend curves for his ACCS inspection through the Barn Report software which is available for CropCool Wireless. Stores can be monitored remotely from either a PC, tablet or smart phone.
“Being modular, CropCool Wireless really is a system for all budgets and expectations,” explains Evans and Pearce managing director Rob White.
“In the coming year we expect to build on its growing reputation here in the UK, helping growers to optimise crop quality and minimise energy use through efficient automated ventilation without the need to be on-site at all times.”
