Cartridge heaters and tubular heaters are both widely used electric heating elements, but they are designed for different applications.
A cartridge heater is a compact cylindrical heating element, usually inserted into a drilled hole or metal block. It is commonly used for molds, dies, hot plates, sealing machines, and other applications requiring localized heating.
A tubular heater consists of a metal tube, resistance wire, and insulation material. It can be manufactured straight, bent, U-shaped, or in other forms. It is widely used for heating air, water, oil, ovens, tanks, and industrial equipment.
| Cartridge Heater | Tubular Heater |
|---|---|
| Compact cylindrical design | Flexible shapes |
| Usually inserted into a hole | Can be mounted or immersed |
| Localized heating | Air, water, oil and surface heating |
| Molds, dies, hot plates | Ovens, tanks, industrial equipment |
The right choice depends on the heating method, installation space, temperature, voltage, wattage, and application.
We can customize both cartridge heaters and tubular heaters according to your specifications, drawings, samples, and application requirements.
