Farm Fans Corporation and Zimmerman Company were brought on board in 2001 with their full line of grain dryers, fans, and heaters.

David Manufacturing Company (DMC) has been a trusted name in the industry for many years focusing primarily on grain handling and in-bin grain drying and conditioning equipment.

DMC's success has mainly been due to it's emphasis on product reliability and customer service. Most DMC products continue to be sold today with few changes to their original designs simply due to their history of reliability in the field.
