Dual Dry Bulk Chemical Storage Silos with integral feeding and dissolving systems from Acrison can be used to reduce the overall height profile of a single high-rate application or feed two different chemicals to one or more application points. They are typically mounted close enough to each other to allow for a single ladder with a safety cage to access one silo roof and a catwalk spanning the two silos to allow for access to the second roof. Fill lines are routed to a single loading point with a single truck-fill panel operating both systems. A security keypad that is wired to automatic valves on the fill line ensures that dry chemicals are being delivered to the correct silo. Means for promoting material flow into the silo’s integral feeders is provided strictly on an as-needed basis without the use of air, eliminating problems that can occur when flow promotion devices operate continuously or on a fixed-time basis. Custom control packages and ancillary equipment are available. 201/440-8300; www.acrison.com
