Coil Heater Working PrincipleElectric Coil heater, also known as cable heater, convert electricity into heat through the process of Joule heating. Electrical current running through the element encounters resistance, resulting in heating of the element.2. Coil Heater StructureThe main features of these heaters are 360o heated area, readily confirms to surface, fast response and quick heat transfer, helical coil design for superior performance, good resistance to corrosion and it can easily be coupled with J or K type thermocouple.The integration of temperature thermocouple for the precise temperature control. It also provides the best combination of physical strength, high emissivity and good thermal conductivity to heat hot runner bushings and nozzles.3.

Coil Heaterimported Raw Materialsa. The coil heater resistance is used German Nickel Chrome wire, can be coiled and straight.b. The insulation material magnesium oxide powder is imported from USA; which ensures the high performance, fast response time and good unformity.Heating photo for example4. Surface TreatmentBlasting and blackening surface treatment, also can provide bright surface.6.Coil Heater Cross Sectionbased on specific requirements and applications, coil heaters are manufactured in different cross sections. Each one is having its own advantages and disadvantages. Basically there are three types of coil heaters. They areCoil Heater Cross SectionRound Coil Heater DiamaterΦ3.0, Φ4.0,Φ5.0Square Coil Heater Diamater3.0×3.0, 3.3×3.3, 3.5×3.5, 4.0×4.0, 5.0×5.0Rectangular Coil Heater Diamater4.0×2.0, 4.2×2.2, 4.5×2.7Cross section 4.2*2.2mmCross section 3.3*3.3mm7.
