Introduction
Dry ice spraying is an extremely environment-friendly cleaning method. It uses dry ice (CO2 compressed in solid form) as a spraying agent. The method allows extremely effective removal of contamination with a minimum of residual waste.
Execution
A spray gun is used to spray the dry ice on to the object. This effortlessly removes contaminants such as grease, oil and ink. The spraying agent evaporates, so it does not release any contaminants. The only thing that remains is the removed material is left behind (there will be no water because the dry ice evaporates completely). This makes dry ice spraying a very environment-friendly way of cleaning. Conventional cleaning methods frequently leave you with a variety of waste, because the contaminants mix with the spraying agent (grit, sand or water).
As this is an entirely dry method of cleaning, it is possible to clean machines and their constituent parts in-line. The advantage is that the part being cleaned does not need to be dismantled, thus reducing the idle time of your machines. This allows a very fast restart after cleaning.
Objects cleanable in this way include:
- condensers
- heat exchangers
- printing presses
- valves
- generators
- electric motors
- ventilators
- conveyor belts
- baking trays
- ovens
- silos
- stud bolts
- motors
