The Principle of  Induction Heating
The RPR induction generator sends alternating current through an induction coil, which generates an electro-magnetic field. This magnetic field induces eddy currents in a conductive material like steel.
Due to the resistance of the steel, these currents are converted to induction heating. The heat is generated below the coating, resulting in quick and clean disbonding.


Fast & Cost efficient
Compared with Blasting and Water Jetting methods:
  • Considerable reduction in man hours
  • ۵-۱۵ times faster on tough coatings
  • Energy costs reduced by up to 75 %
  • Minimum waste handling and disposal



  • Operator friendly; Quiet and no HAV’s
  • No use of dangerous high pressure hoses
  • Produces no airborne waste particles
  • Minimal operator safety equipment or gear required
  • No handling or disposal treatment of grit or water
  • Minimum waste removal – simple logistics and low costs


Environmental Benefits:
  • No airborne particle waste
    • Safer for operators and the environment
  • No water waste or wash-off
    • No contaminate of rivers and sea
  • No grit
    • Minimal waste, reduced handling and disposal
  • No noise
    • Safer for operators and co-workers
    • Local community not disturbed
      This results in lower costs and better  cooperation with local health authorities


Surface and Disbonding
  • Substrates and Precautions
  • Removal of different paints and coatings
  • Coating Disbonding
  • After Treatment
  • Works on carbon steel (magnetic substrates) and some Duplex steel types, depending on the steel properties
  • Rate of disponding and operator speed on the induction head will be determined by thickness, type of coatings and type of steel
  • Requires a minimum steel thickness of 4-5 mm to avoid damage on the backside coatings or insulation material used
Removal of different paints and coatings
Easy removal
  • Most types of standard paints and coatings on steel
  • Hard coatings like epoxies, urethanes, old alkyds etc.
  • Glass fibre linings
  • Fire retardant coatings (PFP’s)
  • Glued and vulcanized rubber
Difficult removal
  • Soft coatings like lanoline
  • Bitumen or other asphalt coatings
  • Chlorinated rubber
  • Zinc silicate and Iron oxide (need too high temperature)
