Introduction
The APR system is a highly effective and extremely efficient way of removing paint remnants from metal surfaces. It is a proven and reliable technique. The induction method is a cost-saving and environment-friendly solution for preparing surfaces:
- very fast removal of coatings
- low-noise and dust-free operation
- no wear products/spraying agents or contaminated water
- removes difficult coatings
- works cleanly and safely
Execution
While the induction method is active, the power supply sends alternating currents through a coil. The local eddy currents that this produces in the carrier material provide accurately adjustable local heating that causes the coating to come away. Afterwards, it is possible to use a simple scraper to remove the coating. Water is used for cooling if the temperature becomes too high.
Concept and fields of application
The system removes coatings, rust, roll oxidation layers and bacteriological growth and also oil and grease from electrically conducting surfaces (like metals). The bonds between the carrier material and the material being removed are severed by means of controlled, locally-limited inductive heating with small energy consumption. The technology is ideal for removing paint remnants, rust, coatings like rubber layers, epoxides and fire safety paint. The coating thickness makes no difference with this method.
Environment-friendly
The system induces heat only where it is needed. Inductive heating does not produce any harmful emissions, exhaust gases, smoke, noise or wastewater. It does not# harm the surroundings. Compared with conventional methods, the induction method consumes only 25% of the energy per surface unit. For the sand spraying/high-pressure hot water methods, the amount of energy needed is approximately 3 kWh per m2. With the induction method, it is 0.75 kWh per m2.
