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, duly painted. Heating elements are made of KANTHAL "A-1" wire and backed by high temperature cerwool insulation, which avoids loss of energy. Temperature is controlled through Digital Temperature Indicator- cum-controller. To work on 220/230 volts or 400/440 volts A.C. Maximum Temp. is 10000C and working temp 9000C. For models of higher temperature the maximum temp. is 12000C and working temp. 11500C.

These are sturdy double walled units with outer chamber made of M.S. sheet duly enamel with inner made up of anodized aluminium or S.S. sheet. The gap between inner and outer chamber is filled with high grade glass wool to avoid thermal losses. Beaded heating elements are placed in ribs, at bottom and sides.
