Terkon stands for DRY ICE CLEANING CONCEPTS.
Dry ice blasting is a gentle way of cleaning practically all surfaces without chemicals.

Dry ice blasting is electrically non-conductive, chemically inert, non-toxic and non-flammable.

Dry ice is electrically non-conductive, chemically inert, non-toxic and non-flammable. Unlike other abrasives, dry ice changes directly from a solid to a gaseous state at ambient pressure without liquefying - it sublimates.

For cleaning, the dry ice particles are accelerated with 5000 liters of air per minute, for example, and hit the material to be cleaned at the speed of sound. This causes the layer to be removed to be locally supercooled and embrittled. Subsequent dry ice particles penetrate the brittle cracks and sublimate abruptly on impact. The carbon dioxide becomes gaseous and increases its volume by a factor of 700 to 1000. In the process, it blasts the dirt off the surface.

The advantages of this minimally abrasive and non-corrosive process are the minimal damage to the material to be cleaned and the fact that no cleaning medium remains for disposal after processing, as the CO2 evaporates into the ambient air in gaseous form. As dry ice is relatively soft, many surfaces are not damaged; even extremely sensitive electrical components, such as circuit boards, can be cleaned in this way. Due to the ability to process the smallest geometries with minimal damage and without dismantling, dry ice blasting is used for cleaning casting molds, stripping paint from assemblies, removing underbody protection in classic and vintage car restoration, cleaning replacement engines and removing paint, rubber, oil, grease, silicone, wax, bituminous coatings, release agents, binders and adhesives, among other things.

In the preservation of historical monuments, paint can be removed without causing major damage, even inside buildings. This technique is also used to remove paint, graffiti and to remove the adhesive roots of ivy and wild vines on walls.
