BUSE-JET Cleaning Process

 

Dry Ice Cleaning has it’s main usages in industrial cleaning and surface removal.  The process is comparable to the conventional sand or water pressure blasting methods.  Instead of sand or water, dry ice pellets are shot at high speeds using compressed air, delivered from an industrial air compressor, at the surface requiring cleaning.  It is also referred to as Dry Ice Blasting, Blast Cleaning, CO2 Blasting and Cryogenic Blasting.

Unit & User

The advantages of dry ice make it one of the most advanced and environmentally friendly alternatives of industrial cleaning and coating removal.   The dry ice pellets literally “melt” upon contact, there is no dry ice residue, only the removed soiling or coating that has to be collected and disposed of.  Furthermore due to the low abrasive quality of dry ice there is no risk of damage to the substrate leaving it clean and undamaged.   As dry ice cleaning is a completely “dry” process it can also be used on most forms of electrical equipment.  Dry ice is also 100% ecologically safe and biodegradable and can be used in environments that must heed strict hygene obligations. 

 

The BUSE-JET advanced cleaning technology accomplishes this effect through four means:  

 

Blasting Process 1-4

1)       The dry ice pellets are shot out of the unit at a speed of up to 300 m/s

2)       The coating is frozen in a split second (micro-thermal shock)

3)       The subsequent pellets are then able to infultrate through the cracked and brittle surface onto the substrate (kinetic energy)

4)       Upon impact the dry ice converts from its hard aggregate state to it’s harmless gas form and expands it’s volume by 700 times.  Through this “explosion” and the high kinetic energy combined with the brittle surface all types of dirt or unwanted coatings are removed

 

Dry ice is produced from liquid carbon dioxide (CO2).  The liquid CO2 utilised in dry ice production is an industry by-product and as a type of "recycling" is not a contributing factor to the Green House affect.  Through atmospheric pressure the liquid CO2 is transformed to a dry ice snow with a temperature of -79°C.  This snow is then pressed into rice-sized pellets for use in the BUSE-JET Blasting Process. 

It is a NON-TOXIC, NON-HAZARDOUS, NON-ABRASIVE, NON-STATIC and NON-EXPLOSIVE cleaning medium.

 

History of Dry Ice Cleaning?

Dry Ice Cleaning as a cleaning method is a relatively revolutionary technology being introduced into the Australian market.  The idea of Dry Ice Cleaning was developed in the 1960s in the USA for aircraft surface cleaning.  The initial equipment were quite bulky, had a complicated construction and a high material usage, resulting in high investment costs. 

 

Only through the new generation of modern blasting units (reduced price and easier handling) that use of a “normal” compressed air supply and a sufficient supply of blasting material (pellets) can the wide use of the process be introduced into the market.
