Department of the series resistance furnace cycle mode of operation for the laboratory, industrial and mining enterprises, scientific research units for elemental analysis and small size steel hardening, annealing and tempering heat treatment, heating, furnaces can be made of metal, ceramic sintering, fusion, analysis, high-temperature heating. 
 Features: 
 Appearance in this series are rectangular electric furnace, furnace shell system and high quality steel with folded edges with angle iron welded. Studio furnace made of refractory, heating elements placed where the furnace and the furnace shell with insulation material between the masonry. 
 Door hinge through a multi-level fixed on the electric panel, door handle door closure is the use of dead weight, through the leverage of the door close to the furnace mouth, turned off the handle just stay put, after decoupling pulled out, the door can be placed on the left. Another mouth with the bottom of the chain and the door safety switch, when the door opened, will automatically cut off electric power to ensure safe operation.
