Our ice blaster equipment uses compressed air to accelerate 3 mm pellets of dry ice to speeds over 150 m / s!
The kinetic energy combined with the very low temperature of the pellets (- 79 ° C) causes the loss of elasticity and cracking of the contamination coating. Following particles penetrate the created cracks and change there from solid to gas.
This process loosens the dirt, but does not destroy (even very delicate) surfaces. It also allows cleaning of materials prone to corrosion, contact with water and electrics.
