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, reattached with thick perforated sheet on the bottom portion,
painted with attractive stove enamel. The distinct feature or perforated
sheet is that, it prevents the temperature control unit from very high
heat.
Heating elements are made of KANTHAL "A-1" wire in coil form
wound on the muffle, embedded in high grade refractory cement and backed
by high temperature cerwool 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 Brick Furnace.
A viewing cap is also provided on the door. Temperature control unit
consists of Energy regulator fitted in front of furnace with two pilot
lamps. The apparatus is complete with one pyrometer, thermocouple,
silver thermal fuse, main lead with power plug to work on 220/230 volts
A.C. The energy regulator dial is arbitrarily marked 0-100 position.
This marking does not indicate temperature. It indicates control level
i.e. at Position '100' maximum electric is allowed to flow to Furnace.
At Position 'O' minimum electric is allowed to flow to Furnace.
