Square Cartridge Heaters Phoenix Thermal Supply

Square and Rectangular Cartridges
SINGLE ENDED SQUARE CARTRIDGE HEATER
SQUARE CARTRIDGE

Phoenix Thermal Supply offers SQUARE cartridge heaters. Unlike square cartridge heaters from other manufacturers, our square cartridge heaters are swaged, allowing them to be used in high temperature and high watt density applications.

Square cartridge heaters are ideal for milled slots in long platens where drilling a long hole would be too difficult.  Square heaters are also much easier to remove from a slot after extended high temperature usage than removing a round heater from a drilled hole.

Our Square and Rectangular Cartridge Heater is designed to distribute maximum heat within a desired area. Because they are completely enclosed, square units will furnish more usable heat for a given wattage than a comparable strip heater attached to the exterior of a mold, platen, or other equipment.

The units are inserted in a milled slot, permitting greater lengths than would be feasible with a drilled or reamed hole. Close dimensional tolerances are held to permit intimate fit for best heat transfer to surrounding medium.

Maximum surface temperatures up to 1200°F. Designations are etched on the sheath to preserve accurate shape and longer heater life.

Square Cartridge Applications:

  • Bag Sealing
  • Long Platens
  • Cutting Jaws
