The intent of the wash tank is to rinse and cool the material during production. The material web is conveyed to the wash tank where one side contacts the water in the tank at surface level. Rolls across the web width are utilized to submerge the web in the water contained in the tank. The web is then conveyed out of the water and sprayed with chilled water spray nozzles on both surfaces for final rinse.


The Wash Tank System is a water tank with a circulation system including a pump and process piping to an auxiliary water tank adjacent to the wash tank. The auxiliary tank includes a heat exchanger with flow through one side of the heat exchanger connected to a process chiller. The process chiller and heat exchanger are used to maintain the wash tank temperature during process. The wash tank is supported on a structural steel framework and is enclosed on all sides. The entire support structure and actual tank include all stainless steel construction. The tank enclosure includes hinged access doors and is manufactured with stainless steel framework and polycarbonate sheeting to allow the process to be viewed during operation. Rolls within the tank are used to submerge the web during travel through the tank. The web transitions from the wash tank water to an exit conveyor to convey the material to the next process. Spray nozzles are used to rinse the web on both sides prior to exiting the wash tank system. A crossover platform and handrail is used to provide personnel a means to cross the line during production.

The wash tank system is part of a series of multiple machines included in this production line. The entire production line, including the wash tank, is controlled by the overall PLC system we provided for the production line. All machine functions are controlled from multiple operator HMI’s (touch screens) at various locations along the line. Any machine included in the production line can be viewed and controlled from any HMI location.
