Cartridge heaters are ideal for generating localised heat in contact applications, often requiring frequent heat-cool cycles. As heating element manufacturers we can build and supply a full range of UL recognised cartridge heaters with customised watt density, seals, thermocouples, fittings and thermal characteristics to perfectly suit your application.
We supply cartridge heaters in a range of standard diameters from 1/8 inch to 1 inch – with custom diameters and lengths available. These heating elements can be manufactured in high or low watt density versions depending on the target temperatures required, and can be fitted with a wide variety of different termination options, lead exits, thermocouples, and end seals to suit the environmental characteristics such as temperature, moisture levels or likelihood of flexing.
Termination options: Swaged in leads, Crimped on leads, Right angle leads, Straight braid, Right angle braid, Stainless steel flexible conduit, Right angle stainless steel flexible conduit, Convoluted conduit, Right angle copper elbow with conduit, Copper coupler, Ceramic beads, Straight pins, Sleeving
End seal options: Lava seal, Cement, Epoxy potting, Epoxylite potting, Teflon, RTV
Fitting optons: Single ended NPT, Double ended NPT or Custom in a choice of brass or stainless steel
Internal thermocouple options: Type J or Type K, grounded or ungrounded, middle or disc end location
