Gradual Heating
Cartridges can be manufactured with (compensated) watt distribution, this means that we can insert the necessary amount or heating wire to control the temperature. Watts distribution is recommended for relatively long cartridge heaters requiring a stable temperature along its whole length.
Different possibilities of construction
Point-by-point heating
Cartridges can be manufactured with inactive areas, where no temperature is required at one point, or several, or to the entry of the connections, so not to damage them.
With four connections
Cartridges can be made with double voltage and different watts within the same cartridge.
