Dry ice is a solid representation of carbon dioxide, a
combination of double bonded oxygen and carbon atoms. This cooling substance
has temperatures lower than water ice. Apart from the frost created by
atmospheric moisture, it leaves no moisture residue.
Due to atmospheric pressure, this non-polar, low thermal
electric conductor element sublimates at 109.3 degrees Fahrenheit. Handling
this substance with no protective clothing is therefore dangerous, since it can
cause severe frost burns. The out-gassing although not highly toxic may cause
hypercapnia.
In dry ice cleaning, pellets are propelled at supersonic
speeds by compressed air guns. This results to micro thermal shock upon impact
that breaks the bond between the substrate and coating. The elevated air
pressure stream rids the surface of dirt in a non-toxic, non-abrasive and dry
process.
Extensively used in aerospace and automotive assembly, this
method eliminates several negative cleaning fundamentals such as: relocation
and dis-assembly, use of solvents, damage to equipment, scrubbing by hand,
drying and cooling time.
A green level cleaning alternative, dry ice cleaning (
Trockeneisreinigung
)
saves downtime periods for
industries, while increasing the reliability and the up-time of electrical
machinery. The process is environmentally friendly, safe for employees and
gently cares for the equipment, with no need for power outage or disposal of
secondary waste.
Complex equipment that constantly requires cleaning such as
heat exchangers, evaporators, chillers, condensers, air exchangers, packaging
plants or generator fans can benefit from dry ice blasting. Whereas the
traditional cleaning process can take days to accomplish, dry ice cleaning
(Trockeneisreinigung ) blasts away contaminants and dirt in span
of hours.
Commercial, residential, historical and industrial
buildings that require cleaning or restoration after a fire utilize this dry on
contact element to eliminate a variety of substrates. The ability of dry ice to
sublimate means a speedy, harmless cleanup for safe removal of toxic soot,
odors and acidic residues.
For bricks, wood beams, electrical cables, stucco, ducts,
plumbing, tight spots, indoor and outdoor brick, stone surfaces and many
others, dry ice cleaning (Trockeneisreinigung ) will perform a thorough noticeably superior clean. This cost
effective method will save on insurance rates and costs that could have
otherwise being incurred by reconstruction or replacement.
Many home owners are adopting this current trend to remove
decades of dirt, grim or paint from their properties. This eco-friendly method
is faster than conventional methods and reducing the hourly labor charges.
Sanitation is a crucial element in pharmaceutical, beverage
and food production sector. The wide range of equipment used by these
industries requires constant cleaning. They utilize the dry ice blasting method
to completely eliminate bacteria, fungi and growth of micro-orgasm, while
safeguarding the equipment from short circuiting.
