2. Full Heat Zone! Especially important when using nylon design tips. Other suppliers stop
their heat at the rear of the nozzle tip, one source even drills through the RT nozzle threads. • Cartridge Heated Nozzles put
the heat closer to the melt.
3. Full 1/2” internal bore to avoid unnecessary restriction of the plastic material! We put the
heat closer to the melt where it belongs. Some competing designs reduce internal bore to • No external heater bands to

5. With our cartridge heater design we have eliminated two causes of failure common to competing cartridge heated nozzles. (High
wattage and lead wire failure.) Low watt density cartridge heaters are absolutely essential to give you the correct response to voltage
increases on powerstats, and on-off switching of controllers. Other high watt density heaters are difficult to control and require higher
amperage when they actually use 25 to 40% of the rated wattage. They cause rapid heat variations, material discoloration or burning,
loss of control, unnecessary current consumption and extremely short heater life. Need more heat; add a forth heater or use a higher
wattage premium cartridge heater from our stock list. PPE heaters outlast the others by a conservative 3 to 1 margin. Even if you’re not
using our nozzles, we recommend you use our heaters for accurate control and longer life.
6. Maximum heated surface of our cartridge heaters gives uniform heat equally distributed over the heater surface less a very small zone
on each end necessary to manufacture. Other designs have a 1” cold zone on the lead end further reducing your actual heat zone.
DANGER! Do not use standard cartridge heaters with crimp on leads, always use swaged-in leads only! We evaluated them thoroughly
and found:
a. The lead wire insulation won’t stand up at high temperatures.
b. The crimp lug can short in the nozzle hole causing serious accidents.
c. The lower temperature rated lead wire will fail and come apart at the crimp with a minimum number of flexes.
d. The wattage is too high and cannot accurately control temperatures.
7. 3/16” diameter cartridge type thermocouple hole drilled between two heater holes is designed to accept our stock cartridge side
sensing thermocouple. Thermocouple should be located near the nozzle tip, not back at the hex. Leads exit in the nozzle hex. Never
use a standard T.C. located in the hex because it’s location relative to the heat is not critical enough and many control problems will
result. We know, we tried it.
