Acrolab Ltd. Round Cartridge Heater HCA

Cartridge heaters are round tubular heaters with electrical terminations on one side. These dependable heaters are made to withstand tough industrial usage. With a tolerance of ±0.002" on their outside diameter to secure a tight fit inside receptacle holes , and rock hard compaction of MgO insulation through swaging, these heaters can attain up to 1500°F sheath temperature. They are available with various termination styles and mounting attachments. In cartridge heaters the resistance wire loops are positioned as close as possible to the outside shell. Because the MgO powder insulation around these loops is compacted by swaging and transformed into a very hard medium, heat transmission is very efficient. Cartridge heaters can have up to 200 W/in 2 watt density. Cartridges are usually supplied with lead wires.
