Washing machine type SKM

Type SKM

  • Robust and user-friendly washing machine for inside and outside cleaning of containers with an open top through spraying with solvent
  • Very good inside cleaning, even with large container diameters, by means of a rotating spray pipe with pointed spray nozzles that moves up and down along the longitudinal container axis
  • Effective outside cleaning due to spray pipes rotating around the containers
  • Separate spraying system for rinsing with clean solvent
  • Tight closing, hydraulic washing chamber door; used as loading platform in front of the washing chamber
  • Position sensor for the door, spraying does not begin until the washing chamber is closed
  • Cylindrical washing chamber, tilted backward, very good draining of the solvent, no corners where residues can accumulate, hence low solvent emissions
  • Closed solvent tank under the washing chamber (no solvent vapors when the washing machine is open), level switch for filling and draining
  • Very powerful centrifugal pump for washing with circulated solvent, separate centrifugal pump for rinsing, pneumatic diaphragm pump for draining
  • External filter with removable basket for protecting the spraying system
  • Strainer for protecting the solvent tank and pumps
  • Explosion-proof hydraulic unit
  • Internal air extraction system with powerful suction fan
  • Automatic washing program: washing – draining – rinsing – internal air extraction; program steps can be selected individually
  • Explosion protection according to ATEX, category 1 (with type examination) for zone 0 inside, category 2 for zone 1 outside


  • Ramp for moving containers onto the loading platform (approx. 150 mm high); the loading platform can also be lowered into a pit for loading at floor level
  • Separate outlet cleaning system if the rotating spraying system of the inside and outside cleaning systems does not clean the outlet well enough (preliminary tests by Renzmann)
  • Warm air drying, removes nonvolatile solvent residues on the container surfaces
  • External air extraction system, supplements/replaces the air extraction in the room/at the workplace
  • Solvent cooler, required for limiting the temperature and solvent emissions, various accessories adapted to the existing cooling water supply system
  • Solvent concentration measuring and regulating system for connection to an exhaust air cleaning system

Type SKM-W

like model SKM, but with the following differences:

  • Suitable for water-based/alkaline media
  • Heating of the washing agent, heat insulation of the washing chamber and the washing agent container
  • Rinsing with water
  • Storage of washing agent and rinsing water in separate, free-standing containers (alternative to floor containers)
  • Explosion protection that is adapted to the washing agent with the washed-off contamination and to the requirements of the installation site
