State-of-the-Art By-product Collection

The PreFilter collects and lessens the buildup of residue in the nitrogen gas circulation loop. It is essential in power cable manufacturing and not to be neglected.


By-product PreFilter for Power Cable

The PreFilter collects and lessens the buildup of residue in the nitrogen gas circulation loop. It is essential in power cable manufacturing. The PreFilter is composed of a container body with multilayer chambers, a cooling unit, pipework, instrumentation and valves.

 

The assembly is highly effective for by-product collection. A sequencecontrolled valve releases the liquid waste into a collection tank. The unit can be disconnected for cleaning. The PreFilter is a pressure vessel. It is calculated and rated accordingly.

 

Cable surface quality is maintained with a PreFilter in place. Cleansed cooling gas optimizes heat exchange throughout. Unwanted defects in cable geometry are thus avoided.

 

Benefits

  • Longer running lengths
  • Extended intervals between maintenance actions
  • Reduced surface defects on the cable
  • Optimum heat exchange in gas cooling circuit
  • Efficient by-product removal.
