Why should a Grain Cooler be used, isn chilling grain using ambient air good enough?
The most important factor when storing grain is to be able to control the temperature. As long as the temperature is being controlled grain having a higher moisture content than usually used for long term storage can be stored safely. Using a PM-LUFT/Tornum Grain Cooler it is always and regardless of ambient conditions possible to chill the grain to a safe storage temperature.
