National Plastic Heater’s flat coil heaters set the standard with respect to precise fit and profiling to optimize the performance of nozzles and other mating components. Available with or without internal thermocouples -Type J or Type K. At 2.5mm(.098”) in    height, the NPH flat coil heater can accommodate today’s design objective of placing nozzles closer to waterlines and minimizing material usage. With a superior width of 3.4mm (.134”) surface contact is maximized resulting in less required heated length and more watts per linear inch.








     National Plastic Heater, Sensor and Control Offers a wide range of performance enhencing options including:



    Outside sheath to improve heating efficiency
    Inside/Outside sheath with sealed end rings to prevent contaminates shortening heater life
    Embedding in brass to create high thermal mass surrounding the heater improving high

        temperature performance and heater life

    Moisture resistant transition head
    High temperature lead and potting options
    Flexible cold section
    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
