Heat Treatment Furnace

Product Details:

Working Temp. Range   : up to 1200ºC.

Temp. Accuracy: ± 1ºC.

Light weight with ceramic Fibre wool insulation (instead of Brick insulation). The outer casing is made of double walled thick P.C.R.C. sheet, finished with attractive powder coating.

Elements are made of KANTHAL “A-1” wire in coil form placed in the ribs of the tiles to have a free radiating heating. Backed by Zirconia cerewool insulation, which avoids loss of energy, this arrangement also assures the most uniform distribution of heat.

The weight & size of furnace is of one quarter and 30% respectively as compare to Bricks Furnace. A viewing cap is also provided on the door.

Additional Information:

• Production Capacity: 10
