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 to change, with or without notice. ## Dimensional Drawings Layout drawings for different models are accessible at the links below: [D600 / D600h Layout Drawing](https://drive.google.com/file/d/1R-3rRSj1XAAD0I1_c6G4ho5KnGaKpryv/view?usp=drive_link) [D900 / D900h Layout Drawing](https://drive.google.com/file/d/1UQH9hExiT-perpzjPU4TtURop5PRjaNw/view?usp=drive_link) [D1200 / D1200h Layout Drawing](https://drive.google.com/file/d/1PoNsVN_0cR2cEJv4HNzZBCVgqgSCIr-0/view?usp=drive_link) [D1500 / D1500h Layout Drawing](https://drive.google.com/file/d/1rz5lgwtvV2rORaVmWa_PfYS30JrLFKHD/view?usp=drive_link) [D1800 / D1800h Layout Drawing](https://drive.google.com/file/d/10MKjwCfDNHj3_TaRLXCFId2jbFh8MKeS/view?usp=drive_link) [D2100 / D2100h Layout Drawing](https://drive.google.com/file/d/1wKXt6G3UC4-iwC04-V7SUT1genvm9lEP/view?usp=drive_link) [D2400 / D2400h Layout Drawing](https://drive.google.com/file/d/1ZNozpUoKsu-PaqkM3BomxrEpHurf6J3H/view?usp=drive_link) [D3200 / D3200h Layout Drawing](https://drive.google.com/file/d/1HauLXjhC2RVgbTNtUNife4IOw7SIkNwV/view?usp=drive_link) ## Specifications and Capacities ### Models D600 / D600h - D1500 / D1500h

1Add 24" (.61m) for a 24" dryer stand set, 36" (.92m) for a 36" dryer stand set, or 48" (1.22m) for a 48" dryer stand set. \ 2Operating burner capacities are based on a 150 deg F (83 deg C) temperature rise for average and 200 deg F (111 deg C) temperature rise for maximum. \ 3Based on 240 deg F (116 deg C) plenum temperature for heat + cool operation, and 240 deg F (116 deg C) top plenum temperature / 180 deg F (82 deg C) bottom plenum temperature for all-heat operation. \ 4Based on discharging grain from the dryer at 17.0% moisture. \ 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), 677 kg/m3 (dry @ 17% moisture), 661 kg/m3 (dry @ 15% moisture). \ 6The information contained herein is intended to assist our customers in selecting the grain drying system that they believe best meets their unique preferences and needs. The performance \ figures and capacities presented in this document 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. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.mathewscompany.com/dryer-operations/dryer-operations/specifications/delta-series.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
