Cartridge heaters are cylindrical electrical heating elements. Protected with a stainless steel sheath, their watt density can reach 50 w/cm2 and their surface temperature can go up to 800cc [1472f]. Mostly used for heating up solids such as injection presses heating plates of various tools, they 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. They are also commonly found in the chemical, electronics,medical equipments, packing. 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.
Available technologies are:
-high-density cartridge heaters [hdc]
For watt densities from 6.5to50w/cm2.
-low-density cartridge heaters [ldc]
For watt densities from 1to6.5/cm2.
-watt density [ w/cm]2 can be a decision factor, but dimensions heater and conditions of use [temperature, vibrations, environment] are also important factors when making the choice between the technologies.
Applications
-plastic processing machineries.
-hot runner module.
-food processing.
-labeling machineries and a lot of other applications.
-heating liquids.
Features
-sheathing mat : ss 304 or ss316
-highly compacted construction improves heater life and reduces the effect of vibration and shock.
-excellent heat transfer.
