The kiln has a low thermal mass ceramic fibre hot face lining with brick piers for element support trays. The type of elements include:

  • Spiral wire wound on trays.
  • Material Kanthal A-1 Ferritic FeCrA alloy.

The element positions for the kiln are:

  • Side wall
  • Door
  • Back wall
  • Kiln car

The element power rating is 180 kw / 60 per zone.


There are 3 control zones in this kiln all controlled by Eurothem high reliability zero crossover burst firing thyristor units.


There are also three "S" type thermocouples.

The kiln was also supplied with:

  • A roof mounted motorised automatic exhaust/cooling damper.
  • Side wall air injection system controlled by a motorised control butterfly valve.
  • Hood over the kiln exhaust/cooling damper with an exhaust chimney.
