Systems for Cleaning Industrial Liquids

Rösler Centrifuges – efficient cleaning of industrial liquids

This technologies utilized for treating process liquids like coolants, sludge from painting operations and other industrial liquids must not only guarantee an excellent cleaning effect but they must also be economical. With its sturdy and sophisticated centrifuge technology Rösler offers a wide range of cleaning solutions which include not only numerous technical features but also excel with their outstanding cost efficiency.  The powerful centrifugal filters from Rösler, available with 2- or 3-phase separation, are usable for a wide range of different cleaning tasks and can easily be adapted to specific applications.

Cleaning of different kinds of process liquids:

  • Machining centers: Maintenance of coolant and grinding oil reservoirs
  • Technical ceramics: Cutting, grinding and polishing
  • Glass processing: For technical and decorative purposes, etc.
  • Wafers for solar applications: Cutting, grinding
  • Paint booths: Maintenance of the water reservoir in wet paint applications
  • ECM (electro-chemical deburring): Maintenance of the water and electrolyte balance
  • High pressure water jet blasting: Aerospace applications
  • Recycling of precious materials: Gold, silver, copper, etc.
  • Wet paint applications: De-watering of the paint sludge
  • General sludge de-watering: Reduction of residual water content

Rösler centrifuges offer many benefits:

  • No delicate filter units that require time consuming maintenance
  • No costly consumption of filter materials like paper, cloth, etc.
  • Improved of tools, pumps and valves in production machinery due to total removal of solid fines from the process water
  • Very small quantities of residual waste materials
  • Waste materials are relatively solid (residual water content reduced to 30%)

Two basic systems are available:
The fully automatic peeling centrifuges, model range RZ 150A, and semi-automatic centrifugal filters, model range RZ 120M.The semi-automatic system RZ 120M is also available as a 3-phase centrifuge, which includes the standard separation of solids from liquids, and also allows the separation of liquids from liquids. This is essential for the treatment of coolants where solid fines and oil must be separated from the water.
