- Model CA 100 - Automatic Fluid Centrifuge



The CA 100 automatic fluid centrifuge is a centrifugal separator for continuous superfine filtering of cooling lubricants and other industrial process fluids. Its main features are high separating capacity down to the smallest particle ranges and automatic sludge draining. The product is thus ideally suitable for bath upkeep on central cooling-lubricant preparation systems and single machines. This prevents the concentration of finest particles of steel, hard metal, silicon, ceramics, graphite, etc. Further areas of application are sludge concentration of backflush filters and full-flow filtering of smaller fluid quantities in superfinishing processes.

  • Very good price/performance ratio
  • Short regeneration cycle thanks to mechanical brake system
  • Frequency-controlled, wear-resistant direct drive via clutch
  • Sound and oil-mist attenuation by shutter flap
  • Electonic vibration monitoring with automatic stop function
  • Separate speed monitoring of motor and drum
  • Automatic flushing of rotor and centrifugal-force valves
  • Flexible control console, can be erected on 2 sides

1. Separation:
The drum accelerates to maximum speed. After entering the centrifuge, the fouled fluid is thrown by the centrifugal forces against the drum wall in a ring shape. Because the dirt particles have a higher density than the fluid, they float outwards and accumulate on the drum wall. A skimming tube takes up the filtered fluid and carries it out of the drum.

2. Drying
The supply of fluid stops after a settable period of time. At reduced speed the centrifugal-force valves open to allow the remaining fluid to leave the drum.

3. Draining
The brake stops and blocks the drum within seconds. Scraper blades rotate in the reverse direction at low speed in the stationary drum. The compact sludge drops out of the centrifuge.

4. Flushing
The drum accelerates to drying speed and fluid is again admitted into the centrifuge for a certain period of time. Then the drying and draining phases start again (see 2. and 3.).
