 Low Profile Coil Heaters                                    High Wattage 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
