Cartridge Heater With Outside Wire

Cartridge heater is one of the tubular heating elements. The heating part is a nickel-chromium heat-resistant alloy wire wound on a magnesium oxide core rod with excellent insulation and thermal conductivity. Between the heating wire and the outer sheath is high-purity magnesium oxide powder as an insulating material, and the air inside is compressed by the machine Into a cartridge heater.
After the main body of the cartridge heater is completed, fixed accessories or threads can be installed according to customer needs. There are many types of fixed accessories or thread structures. Please contact our sales or technical personnel for the best solution.

Advantages:
Small diameter, can be 3-35mm;
The length is not limited, it can be 20-2000mm;
The power is high, which is 2-5 times the power of the normal electric heating tube, and it can achieve a surface area of 20 watts/square centimeter; even a surface area of 60 watts/square centimeter;
It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, long service life, no pollution, and low price. It also saves electricity, is safe to use, can be bent into various shapes, is light, and is easy to disassemble.

MAGMA cartridge heaters are suitable, appropriate devices for applying concentrated heat to solid metal components. Cartridge heater is somewhat similar to tubular heaters structurally but with higher watt densities, usually
custom manufactured to size, sheath, leads, terminals, wattage and voltage as per application or requirement.
Cartridge heaters are used in restricted working areas where localized heating is required for close thermal control.
MAGMA manufactures wide range of cartridge heaters for different numerous applications like heating liquids
(Water, Oil and Glues), Gases such as Air and Solids such as Metal Dies.

MAGMA manufactures 2 types of Cartridge heaters:
HIGH WATT DENSITY
Swaged or High Watt Density Cartridge Heaters
composed of resistance wire (NiCr) spirally wound
on MgO core as per watt density decided. It is inserted in metallic tube selected as per requirement and
space filled with high purity MgO powder. Then it is
swaged to compact the loosely filled powder inside
for achieving high dielectric strength up to the
desired size, diameter and wattage is achieved. The
heat generated by resistance wire is quickly dissipated or transferred to the outer sheath. It is machined
to precise tolerances and straightness.
Swaged or High Watt Density Cartridge Heaters are
fitted into accurately reamed, parallel sided holes for
useful life and fantastic performance. It can operate
at higher temperature and vibration applications.

STANDARD or LOW WATT DENSITY
Low Watt Density Cartridge Heaters comprises of
helical coil (NiCr resistance wire) passed from refractory core and inserted in metallic tube which is predecided by size, diameter and sheath. The remaining space in the tube is MgO powder filled but not
compacted by machine. The end cap is then inserted
on the bottom of the heater and insulated leads are
installed.

Detailed description:
Cartridge heater is cylindrical electrical heating elements. Protected with a stainless steel sheath, their watt density can reach 25 w/cm2 and their operating temperature can go up to 800¡ãc (1472¡ãf)
Mostly cartridge heater is used for heating up solids such as injection presses heating plates or various tools, cartridge heater can also be used for heating up water of gases under certain conditions. Widely used for manufacturing plastic and rubber parts in the car industry or in the food processing industry, etc . Cartridge heaters are also commonly found in the chemical, electronics, medical equipment, packing and nuclear industries
Various cartridge heater technologies are available. The choice of technology will depend on technical specifications required and the application. Unless you know exactly which product you are looking for, we will recommend you the best solution for your needs.
