Cartridge Heaters are tubular formed industrial electrical resistance heating elements in different metric and imperial sizes. Heaters are manufactured to the customer’s specific application to significantly boost process equipment efficiency.

Available in brass, steel, or stainless steel pipe fitting which allows liquid tight installation through threaded openings.  Fittings are brazed to the heater.  Be certain the watt density and sheath material are compatible with the material being heated.  (Available in both NPT and Straight thread with O-Ring)  See chart for sizes available.

Cartridge Heater can be manufactured with flange located at any point along sheath with adequate unheated area.

Conduit Coupler Connector: Flexible conduit is attached with a copper coupler over-lapping the heater by 1/4″. Leads are 14″ long and cable 12″ unless specified.
Fig. 1B and 1C can be attached to stock items.

Additional Variations: Special Wattage Distribution. Specify percentage of overall wattage and length for each section. Typically, the entire length is divided into thirds with the overall wattage split into the following percentages: 40% at lead and bottom third of length with 20% in the middle, or, 35% at lead and bottom third of length with 30% in the middle
