The quantity of main air specified in document BNDUUI01 “Utility Requirements for Gas, Steam, and Thermal Oil Dryers” (in standard cubic feet per minute or scfm) must be available at the dryer main air inlet.
- Page 40 Air and Duct Requirements for Milnor ® Pass-through Dryers 2.1. Is an Inlet Duct Necessary? BNDDUI01.C06 0000086786 A.10 A.11 Released Use an inlet duct to avoid negative air or if hazardous or corrosive fumes are present that could be drawn in to the dryers. Otherwise, consider the facility layout, operational procedures, and cli- matic conditions.
- Page 41 Back Pressure, page 1 automatically. A system of this type could include pressure-sensing devi- ces, a variable-speed booster fan, and a controller. Today, facility designers generally prefer internal lint screens (a Milnor option) or close-coupled ® lint collection systems installed on each dryer. However, if the facility uses a common, powered lint collection system, you can connect the air exhaust from two or more dryers to this system if you run separate ducts from each dryer.
