Description
Used for process heating,Heating Rod Tubes Micro Cartridge Heater is sometimes referred to as an insertion heater. This is because the unit is inserted into a specially drilled hole to heat metal parts or small areas. Each industrial rod heater will come in a specific watt density. Leads and voltages also vary between models.
Heating Rod Tubes Micro Cartridge Heater is available in standard and metric sizes, and they ship within 1-2 business days. Cartridge heating element is offered with a variety of terminations and options.Leads are available in 14", 26" and 38" lengths.
To function efficiently, a micro-cartridge heater must be able to maintain a stable, uniform temperature. Closely controlled work temperatures of up to 1200°F (648.9°C) can be obtained by a combination of heater location and proper wattage output.
It is an economical heater used in applications requiring lower operating temperatures and watt densities.
How Micro-cartridge Heaters Work？
Cartridge heaters consist of a heated wire packed with inorganic powder, packed tightly into a metal sheath. The size, sheath allow, leads, terminals, wattage, and voltage can be customer specified or customized to meet your heating requirement needs.Micro-cartridge heaters are used to heat the metal surfaces of dies, platens, and other types of processing equipment. They play an important part in a wide range of engineering and manufacturing applications.
What is the surface load of cartridge heater?
The surface load is defined in the machinery industry standard as the power per unit area on the heating surface, in watts per square centimeter (W/cm²). The maximum surface load that each type of sheath materials can withstand is different. When inquiry cartridge heaters with REheatek, it is necessary to communicate with REheatek sales or engineers to get the best solution.
How to calculate the surface load? Surface load (W/cm²) = power/ (diameter*3.14*length of heating section) Surface load for different applications: Heating air (dry heating): the surface load needs to be below 8W/cm². Heating mold: normally below 12W/cm². Customized high surface load: can be custom to 18W /cm².

Note: Customize the hole depth of the mold according to the length of the heating section of the heater.
If the hole is too shallow, the heating section of the heater will be exposed after installation and without good heat dissipation environment, which will damage the heating tube and may even cause fire and other accidents.
If the hole is too deep, the heater end part and lead wire may be inside the mold after installation. It may cause problems such as a short circuit between the electrodes.
