This cartridge heater from RS PRO is suitable for immersion heating applications at high temperatures. It's suitable for use at temperatures of up to +450°C thanks to its fibreglass-insulated lead wires.


This compact unit is ideal for heating hard-to-reach areas as it's small enough to pass through a tank wall. Its hardwearing ceramic cap protects the element from vibrations and impact, while deep holes in the cap help prevent wires from fraying for long-lasting performance. The nickel-chromium resistance wire keeps rust and corrosion at bay for an improved service life.


You'll find this type of heating element in a wide range of industrial environments, from warehouses to workshops. To reduce the risk of overheating, we strongly recommend that you use this heater with a control system and temperature sensor.
