Strip Heaters are made of helically wound resistance coil evenly stretched and strung through series of ceramic insulators. Resistance coil is mechanically connected to screw terminals or lead wires for positive connection. The element assembly is electrically insulated and covered by metal sheathing. Sheath metal selection of S.S. 304, S.S.316, Mild steel is available.
This is Basically a Heavy Duty Refractory insulated strip heater with locked on finns for fast transfer of heat to air as the surface contact area increases, also with this results in higher watt density. The finns also act as a cooling option in area where the temperature has to be precisely monitored.
