CARTRIDGE HEATERS
Cartridge Heaters for Industrial Applications
Heatox cartridge heaters are compact, high-watt-density heating elements designed to deliver targeted, reliable heat in applications where space is limited but performance cannot be compromised. Engineered for insertion into drilled holes, these robust heaters offer outstanding heat transfer and temperature control for industrial tools, dies, packaging machines, and scientific equipment.
Manufactured using swaged construction techniques, our cartridge heaters achieve superior thermal conductivity and structural integrity, even under intense thermal cycling. Whether you’re managing a high-throughput production line or maintaining a precision instrument, Heatox cartridge heaters offer the durability and customisation required to meet your specific needs.
Available in a wide range of diameters, lengths, voltages, and lead configurations, every cartridge heater can be tailored to suit your operating environment – from food-grade machinery to heavy-duty plastics processing.

Learn MoreTubular Heaters
Tubular heaters are versatile, robust elements used in air, liquid, and solid heating applications.
Learn MoreSplit Sheath Heaters
Split sheath heaters offer a powerful upgrade from standard cartridges. Once energised, the sheath expands to create a tight fit inside the bore, maximising thermal transfer.
Learn MoreThermocouples
Heatox supplies high-quality thermocouples for accurate temperature sensing in industrial and laboratory settings.

304 Stainless Steel Sheaths
Ideal for oxidation resistance throughout many environments. 316 Stainless Steel and Incoloy® are also available upon request.
High Impact Ceramic Caps
Suitable for high vibration applications and prevent contamination. By employing deep holes in the cap, the fraying of leads is avoided when bent.
High Temperature Lead Wires
High-temperature lead wires are employed for working temperatures up to 550°C.
Nickel-Chromium Resistance Wire
Nickel-chromium resistance wire brings maximum heater life, we evenly wind it for a balanced heat distribution.
High Purity Magnesium Oxide
Selected for maximum thermal conductivity and maximum dielectric strength. It is highly compacted for optimal heat transfer.
