Induction heating cuts coating removal times by as much as 90 per cent compared to alternative methods. It is also the safest, healthiest, most environmentally friendly coating removal method available.
How it works
Using induction heating to remove coatings has been an EFD Induction application for many years. Induction exploits the laws of electromagnetism to generate con- trollable heat. Alternating current flowing through a coil generates a magnetic field. When the magnetic field passes through the coating eddy currents are induced just under the surface of the metal substrate. It is the phenomenon of resistance that generates heat in the area where the eddy currents are flowing. When the steel substrate is heated the coating is dis-bonded and the coating can simply be lifted away from underneath. The process is completely free from contaminates such as abrasives and blast media.
Outperforming traditional methods
Induction heating can outperform traditional paint-stripping methods. Abrasive blasting or disk grinding are generally more labour intensive and come with other issues such as the cost of enclosure or containment and collection of blast media plus the filtration or separation of the coating materials for disposal. In many urban projects these are prime considerations and extremely costly to overcome. In the case where coatings are removed by induction the only waste is the coating itself which in most cases can be swept or even vacuumed like any other workshop waste.
The Coating Removal System efficiently removes industrial coatings of almost any thickness. Contractors and operators report a significant time-saving – up to 90% reduction in time required to remove tough, high-build coatings.
Eco and energy friendly
EFD Induction is committed to providing high performance solutions which minimise the environmental impact of your project. Our Coating Removal System is a prime example as it offers:
Safer working environment. The controlled, localized heat results in significantly reduced fumes and toxic dust.
Easy clean-up. The coating material mainly peels off in flakes rather than being pulverized.
Noiseless operation. Operators can work in public areas without creating a disturbance.
Reduced energy consumption. Fast, easy, accurate and repeatable heat delivery makes the coating removal process extremely energy-efficient.
Controlled, efficient, rapid heating
EFD Induction applications are all about controlled, efficient, rapid heating. We have developed many ways for applying exactly the right amount of heat to exactly the right place, time and time again. In coating removal we can choose to apply any of a number of methods of applying heat and controlling it. We can choose automatic, semi- automatic, controlled-manual or freehand manual. And we can choose between scanning or spot-heating.
