The control center contains the nerve center for the entire asphalt plant. Control centers come in three different styles: portable, relocatable or stationary. Each style comes in various sizes and configurations, including single and split level versions. Frames are of all-steel welded construction and the houses can be picked up by crane without danger of warpage. Control centers are furnished with central heat and air, insulated floors, walls and ceilings. Acoustic ceiling tiles reduce noise in the house. Tinted windows and fluorescent overhead lighting provide superior visibility. A built in ticket window is standard. All models provide an excellent facility control environment and surveillance capabilities with convenience and comfort. All controls are factory installed and fully tested prior to delivery.
