Alliance provided an Aquamaster CB-2400E compact conveyorized belt washer with a heated wash and ambient blowoff. The conveyor speed is adjustable for varying production rates. The mesh-style conveyor is angled at a slight 3% grade through the wash and blowoff zones to aid in the drying process. A sound-dampening package was included in the ambient blowoff zone to lower noise levels to around 85 dBa or lower. Light curtains were added for operator safety. The customer opted to include a mist collection exhaust system, solution heat auto-timer, micro filtration, oil skimmer, and a custom designed adjustable (for shorter cylinders) loader for automatic positioning of cylinders onto the conveyor.
