Drysnow

What is Drysnow?

▸Drysnow is the cleaner that blasts the fine dry ice powder produced from a liquid CO₂ cylinder.
▸Drying and waste treatment is not necessary due to sublimation of the dry ice powder.
▸Suitable for cleaning precision parts. It can also be installed into production line.

Features
▸Particulates and oil can be removed by blasting fine dry ice powder without damage. ▸The fine dry ice powder is produced by liquid CO₂ cylinder. ▸Water and drying process is unnecessary. ▸CO₂ is not hazardous material and thus the cleaning is environmental friendly process. ▸Snow powder sublimes rapidly and does not cause a secondary dirt. ▸Handy type and in-line type are available.
