Stainless Steel Coil Heater

Hot Runner Heaters are compacted for faster and efficient heat transfer. Generally the long 20-3000mm, spring heating ring external using high quality Ni-Cr steel tube, the internal use of high purity magnesium oxide, high temperature resistance wire. With high working temperature, fast heating, uniform heating precision, long service life, can be automatically controlled area, high thermal conduction, while internal heating material damage, external can be reuses. The heaters are annealed to acquire malleability for bending into any shape. Hot runner heaters with built in thermocouple are also available.

Benefits
High Ductility
Allows the heater to be cold-formed into alomost any shape
Low Mass
Allows for quick response in both heating and cooling
Constructed with no Open Seams
Provides the capability of operating in unusual environment, including cryogenic and sub-freezing temperature, high vacuum, gaseous and liquid immersion heaters
Decreases opportunity for corrosion
Constructed of Standrad Stainless Steel 304, Optional S.Steel 316 or Alloy 600
Provides high-temperature corrosion and oxidation resistance along with ideal expansion properties
Heater Sheath Can be Brazed
Allows the permanent attachment of mounted fitting to the heater, contact your Watlow representative
Diameter Ranging 1.02~4.8mm
