  • Pre-heating: For coating, bending, fitting, unfitting, welding.
  • Post-welding heat treatment: Tank, boiler or other metal jobs
  • Heating: Metal sheet heating, Mold heating, shipboard, zinc bath, large& irregular metal parts
  • Pipeline heating: Pipeline oil, pipeline gas, pipeline water, pipeline petrochemical and other pipeline material


  • Digital Display and Adjust for parameters, like output power and temperature setting up.
  • High Efficiency: Electric Power is converted directly to heat power with low power loss.
  • Failure Alert: Once operation occurs, a sounding alarm is activated and error box shown on PLC touch screen.
  • Integrated Module Design: System is more stable and low cost for maintenance.
  • Digital Recorder with optional printer is able to record the temperature data and create chart trends of the heating progress.
  • Accurate Measurement for temperature: Multi-points to detecting temperature; 6 channels for temperature control with ± 3° C tolerance; Evenly heating.
  • Air Cool System allows system work at ultra circumstance: -30 º C~ 50º C
  • IGBT Module: We adapt advanced IGBT Technology.
  • Smart Control: All operation is micro computed and controlled through PLC touch screen.
  • Easy to Install: Quick-release coupling.
  • Easy To Move: Through Lifting Eye or Wheel System.
  • Safe: Automatic Protect for Power Failure.
  • Universal Connector: Water-proof; Insulation.
