WK2500 is the extended version of WK500. Apart from a large sedimentation tank, in which the returning cleaning water is collected, the machine has two tanks with 1,500 liters of water each. While the first tank is used for feeding the machine, the water of the second tank is incessantly led over a high-volume special filter and thus cleared of dirt particles in an intense mechanical way. WK2500 reduces the use of water to the residual moisture on the tarpaulin and to the exchange of liquid in the sedimentation tank. Since 2004, satisfied customers take advantage of this mechanical cleaning machine which offers them a minimum of water consumption.
