Cork-based Alternative Maintenance Services Ltd. was set-up
to satisfy a growing demand for an alternative, environmentally
friendly and low cost cleaning solution in many industries.
Dry ice blasting and Media blasting are two methods Alternative
Maintenance Services specialises in for cleaning a
wide range of equipment in all industries.
Dry ice blasting is a new 'dry cleaning' method and
is increasingly used worldwide for cleaning injection moulding
equipment, medical device manufacturing equipment, printing
equipment, power generating equipment, food and beverage equipment
and fire restoration.
It is a process in which particles of solid carbon dioxide
- commonly known as dry ice - are accelerated in a pressurised
air stream to impact a surface to be cleaned. Upon impact,
the dry ice pellet creates a micro-thermal shock which breaks
the bond between the coating and the substrate. The thermal
shock is caused by the extreme cold temperature of the dry
ice, which is -79°C.
The high pressure air stream removes the contaminant from
the surface, while the dry ice pellets vaporise upon contact
with the surface.
Traditional abrasive blasting methods clean through a chiseling
action, damaging the underlying surface. There are no harmfull
chemicals or liquids used in the process.
Dry ice blasting has been approved by the FDA, EPA and USDA
as an acceptable cleaning method.
