Pennybottom Cartridge Heaters – Power Variations

Type DW: Distributed Wattage

Cartridge heaters can be designed to vary the wattage along the length of the heater. Specify the number of zones and the required watts and length per zone starting from the disk end. Leads can be connected externally or internally. The picture shows a heater with Type N externally connected leads. Heaters with other terminations may require a longer cold section at the lead end.
