Read more to learn more about dry ice blasting and why it might be the perfect solution for your next surface cleaning challenge. Dry ice blasting is a non-abrasive cleaning solution where dry ice pellets (CO₂ in solid form) are used as a Small Business The dry ice pelets vaporize immediately on contact with the surface being cleaning. Dry ice cleaning is a completely dry process, so even delicate electrical equipment and wiring can be cleaned without damage.
This leaves you with a very clean, dry, and intact surface with no residue. If the project requires both methods, we are prepared to combine our soft dry ice blasting media with an abrasive media blasting technology for successful completion. Let us show you why our approach issuperior to traditional cleaning and restoration methods. Even persistent substances such as greases, oils, glues, food residues or paint can be removed. The CoolMaster can be used for far more applications as one might initially think of.

We offer products with a range between 20 and 1,000 watts and provide training to ensure your employees can get the most from their laser cleaning solutions. Dry ice blasting machines vary by model, but dry ice usage can be as low as 0.5 pound per minute or as high as 6.0 pounds per minute.
Dry ice blasting, otherwise known as dry ice cleaning, is a more aggressive form of precision cleaning using dry ice pellets instead of CO2 snow. The latest in dry ice blasting technology, the CoolMaster was developed with the aim of permanently changing the cleaning industry. The CoolMaster is a product which sets new cleaning standards in all industries.
Hearing protection is required because of the extreme noise generated during the blasting process. The blasting gun and dosing unit are electrically, rather than pneumatically, driven, so there is no risk that they will become iced up and fail. The aluminium blasting nozzles have rubber insulation and can be changed even when they are icy. Thermal energy from the abrupt cooling to -79°C causes a thermal shock effect and produces fine cracks in the top layer of material to be removed causing it to go brittle and crumble away from the surface. DIP 100 Dry Ice Pelletizer New ICEsonic DIP 100 Dry Ice Pelletizer is capable of producing 100 kg/h of continuous high density dry ice.
Dry ice blasting is completely non-toxic and no hazardous chemicals are used. Costs connected with the disposal of blasting media, chemicals or solvents are saved. Dry ice cleaning can be used in many manufacturing environments to clean production equipment , molds, tooling, and electronic equipment.
Polyolefines have to be pretreated by flaming, corona or plasma treatment, and metals by sand blasting , etching or anodizing. 17.The process generates minimal waste, primarily water and removed contaminants. The beauty of it all is that the CO2 quickly dissipates into the gas carbon dioxide, so there is very little blast residue to clean up — only the failed paint film or removed contamination.
This means that CO2 snow lacks the impact energy compared to similar-sized CO2 pellets used in dry-ice blasting. Second, this is a non-equilibrium process and using equilibrium phase and pressure–enthalpy diagrams serves only as a guide. Stating that the process goes through the triple point ignores the non-equilibrium nature of the process. By sending nanosecond length pulses of laser light towards a surface, laser technology quickly and efficiently removes contaminants from surface areas. When it interacts with contaminants that absorb laser light, the contaminants or coating particles will either turn into a gas or the pressure of the interaction will cause particles to free from the surface. The dry ice used can be in solid pellet form or shaved from a larger block of ice.
While dry ice cleaning is virtually non-abrasive, the material is still being propelled at 80 psi (5.5 bar) or higher, which can damage softer surfaces, like soft woods and soft plastics. Non-abrasive—because dry ice pellets are virtually non-abrasive, they won’t damage the substrate of the surface being cleaned. In dry ice applications, high-density CO2 pellets are propelled via a high-velocity stream. The media makes contaminants and coatings brittle, helping them break off and leave the surface underneath. Luckily, ESCA Blast is your one-stop-shop for all of your dry ice blasting needs.

Cold Jet has developed a system that allows for easy entry into tight places, otherwise impossible to reach using traditional cleaning methods. No other company can provide the variety of essential nozzles and accessories to ensure complete removal of foreign particles from the multitudes of angles that a challenging job often requires. Dry ice blasting can be extremely dangerous, as it can cause a buildup of carbon dioxide within enclosed spaces. Because of this risk, dry ice requires a well-ventilated space, or else the operator and any employees within the space may experienceasphyxiation. Manufacturer trained technicians on staff to service and repair all major brands of dry ice blasting machines and after cooler dryers.
This mode is not suitable for hydrocarbon removal unless there is a velocity boost. Shows an example of a heavily stained optic that was cleaned on one side. 3.The process may create a surface profile on a noncorrosion resistant steel surface. A smooth surface profile is key parameter in superior paint performance. 14.Ice blasting is safe to use in confined areas or where adequate ventilation is an issue. 5.Water ice at low temperature has nearly the same hardness as stainless steel or glass.
Dry-ice blasting involves propelling pellets at extremely high speeds. The actual dry ice pellets are quite soft, and much less dense than other media used in blast-cleaning (i.e. sand or plastic pellets). Upon impact, the pellet sublimates almost immediately, transferring minimal kinetic energy to the surface on impact and producing minimal abrasion. The sublimation process absorbs a large volume of heat from the surface, producing shear stresses due to thermal shock. This is assumed to improve cleaning as the top layer of dirt or contaminant is expected to transfer more heat than the underlying substrate and flake off more easily.
It also does not require supplementary chemical agents within the cleaning process, making it highly effective for cleaning on the sensitive materials that may be found in regulated cleanrooms. The combination of extremely high cleaning speeds and a wide range of nozzles means that even normally inaccessible items can be cleaned rapidly. Only the contaminant that has been removed remains to be disposed of, and this can usually be swept or vacuumed from the floor. Dry ice pellets are accelerated by compressed air to high velocities thus impacting the contaminant and provoking fractures. In a poorly-ventilated room, the cleaning process could cause a build-up of carbon dioxide and lead to asphyxiation.
Dry ice pellet usage is measured in pounds per minute for blast cleaning. In 1959, Unilever filed a patent for using dry-ice blasting (or water-ice blasting, or some combination of the two) as a method of removing meat from bone. It is believed the US Navy, in 1945, were the first to experiment with dry-ice blasting. They were interested in using the technology for various degreasing applications. Due to the blast media sublimating without residue, dry-ice blasting finds use in the semiconductor, aerospace, and medical device manufacturing industries. Dry ice blasting is not inherently dangerous, but there are safety precautions one should always follow.
