EcoCold 500/30 Classic

The compact and mobile EcoCold 500/30 Classic removes dirt from the smallest corners. The high-pressure water unit has been specifically developed by WOMA for use in professional high-pressure cleaning. It provides pressure up to 500 bar (X) and a capacity of up to 30 l / min,(X) as well as many opportunities to work efficiently and safely.

Advantages :

  • Suitable for cleaning: concrete formwork, facades, cleaning of filters in the industry, and the removal of organic growths on ship hulls and buoys.
  • The pressure controlled switch off the power (X) when there is no water supply to prevent dry operation.
  • The slow start of the electric motor can slowly initiate the motor and pump. This prevents leakage and increases service life.
  • The wheels and control of the machine are equipped with brakes so that the EcoCold also can drive up slopes.
