The CO2 cleaning process is based on liquid carbon dioxide. Carbon dioxide is a non-flammable, non-toxic, naturally occurring gas that, when subjected to pressure, becomes a liquid and is a very effective solvent. Since the solvent is recognised as being environmentally friendly, it is not subject to any environmental regulations or liability potential from soil or groundwater contamination.

Every component on our liquid CO₂ machine, which is subjected to pressure, is built to the most stringent pressure vessel codes available. The storage tanks are tested and lifetime certified. They are designed for a long life of worry-free operation. Many common items (i.e. scuba tanks and restaurant tanks) operate at higher pressures and have been used safely for many years. As long as these devices are treated properly, there is no need to fear the operating pressures.

Carbon dioxide (CO₂) is a colourless, tasteless, odourless gas that is found naturally in our atmosphere. Though it is present in relatively small quantities (about 0.03% by volume), it is one of the most important gases we know of. It is important because it is part of the basic life cycle in nature. Humans and animals give off CO₂ which is used by plants to help them grow. Plants, in turn, release oxygen, upon which we depend for survival.

Equally important are carbon dioxide’s wide range of chemical and physical properties that make it a key part of countless industrial applications - in gaseous, liquid and solid forms.

• CO₂ as a gas: The commercial production of carbon dioxide begins with CO₂ in a gaseous state. CO₂ gas is inert, a property that makes it extremely useful for such applications as purging flammable vapours from tanks and pipelines. It also provides a shielding atmosphere around flammable materials during welding as well as around perishable foods during storage and transfer. CO₂ is used for carbonation of soft drinks and beer and to reduce the alkalinity of treated water.
   
• CO₂ as a liquid: Liquid CO₂ is produced by cooling and compressing carbon dioxide gas under pressure. The liquid produced in this process is a clear, transparent fluid that flows readily at temperatures between +87.80F and -69.90F (liquid CO₂ is normally delivered at 00F under 300 psi.) Below -69.90F, liquid CO₂ freezes to form solid carbon dioxide, more commonly known as dry ice.
