Electric Heating Tubes / Heating Plates – Product Description

Electric heating tubes and heating plates are highly efficient, energy‑saving heating elements that convert electrical energy into heat via resistance wires or ceramic heating cores. Their surfaces can directly contact media or workpieces for rapid and uniform heating. They are widely used in air heating, oil tank heating, mold auxiliary heating, ovens, laboratory equipment, and various industrial and domestic applications.

Key Features

  • Rapid Temperature Rise
    Made with premium resistance alloys (NiCr, FeCrAl) or ceramic heating cores for quick thermal response and fast reach of set temperatures.

  • Uniform Heating
    Heating plates use composite lamination technology, and tubular elements are densely arranged to ensure even heat distribution with no hot spots.

  • Energy Saving & Eco‑Friendly
    Surface treatments such as nitriding or nickel plating boost thermal conductivity and extend service life; efficient insulation design minimizes heat loss.

  • High‑Temperature & Corrosion Resistance
    Tubes can be made of stainless steel or aluminum alloy; heating plates on ceramic substrates, suitable for –50 °C to +800 °C conditions and various chemical environments.

  • Flexible Installation
    Tubular elements support direct‑insertion, flange, threaded, or clamp connections; heating plates can be fixed by adhesive, screws, or embedded into grooves to meet diverse installation needs.

  • Customizable Specifications
    Power, voltage, length, and thickness are all customizable, and options include single‑phase, three‑phase, and DC power supplies.

  • Household appliances (electric kettles, heated blankets)

  • Any application requiring localized or surface heating

Installation & Maintenance

  1. Installation

    • Confirm matching of power supply voltage and rating;

    • Ensure tight contact between heating element and workpiece to avoid air gaps;

    • Provide reliable grounding to prevent leakage.

  2. Commissioning

    • Power up gradually and monitor sensors and controllers for proper response;

    • Adjust power or temperature settings step by step to prevent overshoot.

  3. Maintenance

    • Regularly inspect terminals, insulation layers, and sealing rings;

    • Clean surface dust and debris to maintain adequate heat dissipation;

    • On fault detection, immediately power down, stop operation, and replace or repair the heating element.
