High-Density Cartridge HeatersDownloadsInquiry Form

High density cartridge heaters distinguish themselves by their high compression and therefore especially efficient heat emission. That's why we produce them with a ground surface for a H7 fit. The resistance wire is spooled on a ceramic core as shown on the photograph. Afterwards the space between wire and cartridge sheath is filled with MgO. Finally the cartridge is swaged and thus compressed. Advantage of this construction is the resistance wire's short distance to the sheath, the resulting very good heat emission and the excellent control response.
