Low Profile Coil Heaters-Custom Coil Heaters

Low Profile Coil Heater-1.8 x 3.2 mm Higher Wattage Low Profile Coil Heaters


National Plastic Heater has responded to industry calls for a thinner coil heater with integral thermocouple option by creating the 1.8mm x 3.2mm flat low profile coil heater. The 3.2mm width allows for greater watt density while the 1.8mm height allows OEMs to design drops closer to each other and, also, closer to coolant line. The 3.2mm width delivers higher wattage per linear inch compared to mini coils



National Plastic Heater, Sensor and Control offers a wide range of performance enhancing options including:


  • The 1.8 x 3.2 coil, delivers the performance of standard NPH coil heaters in a thinner profile.
  • Thinnest available coil heater with an integrated TC (J or K)
  • Flexible Cold section
  • Moisture resistant transition head, that is sealed for moisture resistant applications available
  • High temperature lead and potting options
  • Build to order & ships in 7 business days
  • Wide variety of standard and custom lead exit options

National Plastic Heaters, Benefits and Advantages:

  • Custom wound from straight stock for same day shipments
  • Flexible cold section
  • Higher watt density than a cable heater
  • Resistance wire centered for more repeatable heat profile
  • Sealed transition head for moisture resistant applications available
  • NPH can wind coil heaters from stock and ship same day or build to order in 7 business days
