Raas Heat Tech offers Cartridge Heater both High watt and Low watt Density. These heaters are designed for a long life and outstanding performance.
HIGH WATT DENSITY CARTRIDGE HEATER:
The Construction of this type varies from Low Watt Density Cartridge Heater in two aspects. The space between Ceramic bricks & the tube filled with selected grain size of high purity Magnesium Oxide (MgO). This is swaged to an extent of producing excellent heat transfer capability and dielectric strength and long life. The tube used to house the ceramic brick arrangement is of SS 316 sheath or In coloy 800 with maximum watt density of 12 Watt/sq.cm.
LOW WATT DENSITY CARTRIDGE HEATER:
Coil is made up of helically wound coil of Nickel Chrome wire. This coil is passed through specially designed circular ceramic bricks in such a way that it is evenly stretched to form stacks of ceramic bricks. This arrangement is housed in a tube of SS 304 Sheath with maximum Watt density of 4 Watt/sq.cm.
