Typical application

ARKAL 65 V is adapted to superstructure application with complex and large shape. Used in:

  • working end and wide feeder superstructure for various type of glasses,
  • flat arches in canal and spout lip area for float glass furnaces.

Can sustain more severe operating conditions in term of temperature and creep resistance compared to ARKAL 60 V.
