DRY ICE Manufacturing
Our dry ice (DI) is made from liquid carbon dioxide (CO2) that is compressed through high pressure into solid dry ice pellets ranging from 3mm to 12mm diameter at a temperature of -85°C.
Dry ice has a variety of uses such as:
• DI blasting
• Refrigerating medication
• Transport refrigeration
• Shrinking fitting metal parts
• Freeze drying
• Special effects
• And much more…
DI blasting is a revolutionary blasting method that uses small, compact dry ice pellets as the blasting material. The pellets are accelerated in a jet of compressed air similar to that used in traditional blasting methods.
This method is designed to replace high-pressure hosing, other traditional blasting methods and other cleaning methods that involve the use of hazardous chemicals, solvents, etc.
The unique feature of DI as a blasting material is that it vaporises on contact with the surface to be cleaned. Treated surfaces are therefore left dry and clean, without residues of detergents or blasting materials. As the process is completely dry and non-conductive, DI blasting can be used where other methods are unsuitable. For example, electric motors and equipment with electric, pneumatic or hydraulic components can be cleaned directly using dry ice blasting.
What is dry ice blasting used for?
In the Electrical Industry this technology is most commonly used to clean dirt and other conductive substances built up on High Voltage insulators, where if left this will lead to high voltage shorts circuits causing long down times to equipment while power is restored. Another common use is to clean the residual carbon left on switch boards after a voltage explosion has occurred.
Blasting with DI is ideal for removing coatings such as adhesives, varnish, oils, grease, coal dust & soot, mould release agents and bitumen.
No detergent or blasting material is left after treatment. This makes the system highly suitable for industries that require a high degree of hygiene – the food and pharmaceutical industries for example.
Environmentally friendly, dry ice is completely non-toxic. As no hazardous chemicals or solvents are used in DI blasting, operators avoid being exposed to hazardous fumes and other dangers during cleaning. In contrast to high-pressure hosing, polluted drain water is avoided.
