TumbleJet Duo While one box is being washed, you can take out the washed box and put the next one in. This allows a capacity of 50 boxes per hour to be achieved by 1 forklift driver. The TumbleJet Duo is ideally suited for large arable farmers, cold stores or bulb companies that wash a significant amount of boxes. Thanks to a simple insert frame, the TumbleJet Duo is suitable for all common box sizes. AgrinServ has several machines for rent. Used machines can be purchased at a competitive price. Price depends on year of construction and number of washed boxes. Available from EUR30,000 It is also possible to first gain experience with the TumbleJet Duo on a rental basis and purchase the machine if you are satisfied.
