# Modular Tower Series 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. ## Dimensional Drawings Layout drawings for different models are accessible at the links below: [10530 Layout Drawing](https://drive.google.com/file/d/1eTwEWZg8HuAt2hGn9561wtzKj4wJJjWX/view?usp=drive_link) [10740 Layout Drawing](https://drive.google.com/file/d/1y-jAYvgZDjQMsvJ2PEIyQx1g6a0zqr0h/view?usp=drive_link) [10950 Layout Drawing](https://drive.google.com/file/d/1KWRvbYT_bKzrPi3-pv2QU8ZHSzovyp-W/view?usp=drive_link) [101160 Layout Drawing](https://drive.google.com/file/d/1pRijhUO_wktY4ed6SHxrxK1co9Au7Tv7/view?usp=drive_link) [101375 Layout Drawing](https://drive.google.com/file/d/1lah_s0cCTMRmMjSiz0blhF6pjBox5-Qj/view?usp=drive_link) [12-20-100 Layout Drawing](https://drive.google.com/file/d/10Mei0EjiQV7cDtJVgnTfQwe8ua3W_O50/view?usp=drive_link) [12-24-125 Layout Drawing](https://drive.google.com/file/d/1BTEWjX3CBaPTqYxbimp2zl59jaQg1Csp/view?usp=drive_link) [12-28-150 Layout Drawing](https://drive.google.com/file/d/10MuSz9JD5APJw-IP8XFnrBqNXbNP1p16/view?usp=drive_link) ## Specifications and Capacities ### Models 10530 - 101160

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).
