Blasting machines

We have the solution for your cleaning problem: CO2 Snow Blasting and CODry Ice cleaning

This technology can be used as a stand-alone solution or installed upstream into existing processes. This process guarantees residue-free cleaning of components and thus flawless coating.

Venjakob Dry Ice cleaning for perfectly cleaned surfaces

Whether CO2 snow blasting or CO2 dry ice cleaning, our blasting systems represent perfection down to the smallest detail, from small 3D parts to large workpieces in large batches. Our blasting systems are suitable for any application. CO2 cleaning can be used as a stand-alone solution or installed upstream into existing processes. The process achieves residue-free component cleaning and thus enables a flawless surface for subsequent processing such as coating.

How CO2 cleaning works

Schema Abbildung CO2

CO2 - Dry Ice Cleaning

Dry ice cleaning uses solid carbon dioxide – dry ice – as its blasting medium. Dry ice cleaning works in a way that’s comparable to abrasive blasting or hydroblasting. Solid CO2 pellets (solid carbon dioxide, often referred to as “dry ice pellets” are used rather than water, sand or other abrasive materials. Made from a mixture of compressed air and dry ice particles, the cleaning jet hits the surface to be cleaned at high speed.

CO2 - Snow blasting

A cold burner produces its own dry ice from liquid CO2. The cleaning blast consists of a mixture:

  • CO2 snow particles
  • CO2 gas that’s not converted into particles
  • Compressed air
