Cryoclean snow+ industrial cleaning process launched

BOC, the UK and Ireland's largest supplier of industrial and medical gases, launched the Cryoclean snow+ industrial cleaning process at BOC's Manufacturing Technology Centre in Wolverhampton at the end of January.

Cryoclean snow+ combines dry ice blasting (using CO2 dry ice crystals) with sand blasting to provide a flexible industrial cleaning method for a wide range of industry sectors. This new process can be used to clean industrial products such as machinery, process equipment, and conveyor belts. Cryoclean snow+ is also useful in the new, fast-growing, additive manufacturing sector, where it can be used to remove oxides from the surfaces of a number of materials, including steels and aluminium, and to clean polymers. By changing the ratio of CO2 and abrasive material, the operator can adjust the intensity of the cleaning process to match the condition of the surface. This is particularly useful where cleaning challenges vary within a process flow, with relatively clean areas followed by heavily soiled, chemically altered, or even corroded zones.

Developed by BOC and its parent, The Linde Group, Cryoclean is a completely dry cleaning process in which liquid CO2 is pressurised to 60 bar, creating tiny dry ice crystals known as snow. When the snow is accelerated onto the component using compressed air, the contaminant becomes brittle. The gas jet then permeates cracks and lifts the contaminant off the surface - after which it is expelled through exhaust systems.
Stuart Wilders, BOC's market sector manager for advanced manufacturing, said: "BOC is delighted to introduce Cryoclean snow+ to the UK and Ireland industrial cleaning market. This innovative new technology delivers the same standard of cleaning faster and more efficiently than traditional wet cleaning. It is also more environmentally friendly and requires a smaller footprint."
