The company's Dry Ice Blast Cleaning system fires dense, dry-ice (CO2) pellets at high speed against a dirty surface and ensures all dirty product lands onto the ground as pellets rapidly evaporate - resulting in a clean and dry surface.
This application can be performed on-site with little dismantling and is suitable for generators, switchboards, circuit breakers, electric motors and various other electrical and mechanical applications.
When shot at high speed onto a dirty surface, the dry ice pellets sublimate on impact into a harmless gaseous state.
This leaves the surface clean, dry and undamaged, while keeping the surrounding area free from secondary waste and debris.
Wärtsilä's Dry Ice Blast Cleaning process is a ‘cool' cleaning process and not abrasive, and can be regularly used on hard or delicate surfaces.
The dry ice also has a sub cooling effect - the thermal shock shrinks debris particles and loosens them from the surface.
It is this kinetic energy that blows dirt away quickly and efficiently.
Generator cleaning in particular can now be expedited with very short downtime.
CO2 cleaning is available for land-based applications as well as offshore where space is even more limited for conventional forms of cleaning.
When proper procedures are followed, dry ice cleaning will not harm the internal components of a generator.
Wärtsilä's Dry Ice Blast Cleaning is effective on a variety of surfaces including metals, plastics, ceramics, fibreglass, composite and stainless steel.
The entire process complies with relevant environmental, health and safety standards.
