Light weight with ceramic fiber wool insulation (instead of brick insulation). The outer costing 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 of perforated sheet is to prevent the temperature control unit from very high heat. Heating elements are made of KANTHAL A1 wire of coil form embedded on the muffle with high grade refectory cement and backed by high temperature cer-wool insulation which avoids loss of energy. These arrangements will ensure the most uniform kind of distribution of heat. The weight & size of furnace is of one quarter and 30% respectively as compared 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 V. The energy regulator dial is arbitrarily marked 0-100 position. This marking does not indicate temperature. It indicated control level i.e. at position 100 max. electricity is allowed to flow to furnace. Maximum temp.950ºC working temp.900ºC
