Increase your washing capacity with a Tunnel Washer MachineTunnel washer machines are designed to wash heavy and heavy loads of laundry. In other words, we can define tunnel washers as continuous washers. Tunnel washer machines, which take out more clean laundry from one end of the tunnel to the other, have become the choice of those who trade in this field with their efficiency. The screws used are made of perforated metal, so they can travel in one direction through the washing machine while water and washing chemicals move in opposite directions. Thus, laundry passes through pockets with increasingly cleaner water and fresher chemicals.
