With this stainless steel plate processing machine, the water washable plates are processed in a very short period of time. The plate is attached to the self –adhesive wash table and is washed out in a mixture of water and 1% soap, at a temperature of 40 degree Celsius. To ensure continuous operation, the water is filtered in two steps. First, the rough particles are filtered through a membrane unit and the smaller polymers are removed. This allows the machine to continuously re-use the water. After working hours the machine can be set to continue water cleaning for e.g. 2 hours before shutting down. The membrane is cleaned automatically by means of a backflush system.
