The performance figures and capacities referenced herein are only estimates, based on calculated simulations, and do not constitute express or implied warranties. Many factors influence the grain drying process, including ambient temperature, relative humidity, grain variety, grain quality, grain temperature, dryer operating temperatures, dryer add-ons and accessories, and dryer condition, maintenance and operation. Specifications and capacities are subject ot change, with or without notice.

The performance figures and capacities presented in this brochure are only estimates, based on calculated simulations, and do not constitute express or implied warranties. Many factors influence the grain drying process, including ambient temperature, relative humidity, grain variety, grain quality, grain temperature, dryer operating temperatures, dryer add-ons and accessories, and dryer condition, maintenance and operation. 5Capacities in metric tonnes/hr are based on a grain bulk density of: 749 kg/m3 (wet @ 25% moisture), 703 kg/m3 (wet @ 20% moisture), 661 kg/m3 (dry @ 15% moisture).
