产品描述
Cartridge heaters are most frequently used for heating metal parts by insertion into drilled holes. For easy installation, the heaters are made slightly undersize relative to their nominal diameter. The CIR high Watt density cartridge heater is supplied with an Incoloy sheath, type “F” long life stranded flexible leads and high watt densities. The Incoloy sheath allows operation at sheath temperatures to 1500°F. The CIR series cartridge heaters feature a high temperature Incoloy sheath and swaged construction, which allows for higher Watt densities and maximum life at higher operating temperatures. The maximum sheath temperature for the CIR series is 1500°F. The CSH series cartridge heaters also feature a swaged construction for higher Watt densities and efficient heat transfer from the nichrome resistance wire to the surface of the heater. The maximum operating temperature for the 300 series stainless steel sheath is 1250°F. The CSS series cartridge heaters are constructed of coiled resistance wire which is wound through ceramic cores, and a 300 series stainless steel sheath. They are available in lower Watt densities and in diameters as small as 1 /8 ".
