When addressing industrial cleaning challenges such as residue buildup, production downtime, and the risk of damaging sensitive surfaces, selecting the appropriate cleaning method is essential. Nu-Ice® Dry Ice Blasting provides a non-abrasive cleaning approach designed to reduce cleanup requirements while preserving surface integrity. This article examines the differences between dry ice blasting and sandblasting, along with other common methods such as wet or chemical cleaning, using the Commando® 55 dry ice blaster as a reference. As a manufacturer of industrial dry ice blasting equipment, Nu-Ice® offers cleaning systems developed to support a wide range of industrial maintenance and surface preparation needs.
Industrial cleaning methods vary significantly depending on surface type, contamination level, and operational constraints. Sandblasting is commonly used for aggressive material removal but can introduce abrasive media, airborne dust, and extended cleanup processes. Dry ice blasting, by contrast, relies on controlled pellet impact and sublimation to remove contaminants without abrasive contact or secondary waste from blasting media. Understanding the operational differences between these methods allows facilities to evaluate which approach best aligns with equipment sensitivity, maintenance requirements, and production workflows.
Dry ice blasting is a non-abrasive cleaning method in which compressed air accelerates dry ice pellets through a nozzle toward a contaminated surface. When these pellets contact the surface, they sublimate — changing directly from solid carbon dioxide into gas — and help dislodge residues without introducing abrasive media or moisture. Because the dry ice vaporizes on contact, the process produces no secondary waste from the blasting medium itself, making it suitable for applications where cleanup time is a priority and where abrasive or wet methods are inappropriate.
Kinetic Impact
In dry ice blasting, compressed air propels dry ice pellets at velocity so that their impact helps break the bond between contaminants and the underlying surface without abrasive damage.
Thermal Effect
As dry ice pellets strike the surface, their extremely cold temperature creates a rapid temperature change at the point of impact. This change can assist in weakening the attachment of residues, facilitating removal during blasting.
Sublimation Expansion
Because dry ice pellets sublimate immediately upon impact, they expand into gas and leave no blasting media behind. This expansion supports detachment of contaminants, while the absence of media residue simplifies post-blast cleanup.
A dry ice blasting system consists of several integrated components that work together during operation. An air compressor supplies pressurized air, which carries dry ice pellets from the hopper into the airflow. A metering system regulates pellet delivery based on cleaning intensity, and the hose and nozzle assembly directs the air and dry ice stream to the target surface, enabling consistent cleaning performance.
Nu-Ice Age, Inc., operating as Nu-Ice® Dry Ice Blasting, is a U.S.-based manufacturer of industrial dry ice blasting equipment. All of its Commando® dry ice blasters are engineered and built in the United States and are designed to deliver controlled, dry cleaning without secondary blasting waste. The company’s product line includes dry ice blasters of various capacities along with blasting accessories such as nozzles, guns, hoses, and air quality conditioning equipment like the Command Air® Aftercooler.
Nu-Ice® dry ice blasters are designed with operator usability in mind and utilize a blasting gun compatible with interchangeable nozzle options, allowing users to adjust blast patterns to suit different surfaces and contamination types. Available nozzle configurations support focused or wider coverage depending on the application. Nu-Ice systems are also designed to work with moisture management components that help reduce water in the compressed air supply, supporting consistent dry ice delivery and helping prevent pellet bridging during operation.

The Commando® 55 Dry Ice Blaster is intended for industrial cleaning applications and features a dry ice hopper capacity of approximately 55 lbs (25 kg). The machine measures about 33.25 inches in length, 23 inches in width, and 39 inches in height, with an overall weight of roughly 234 lbs (106 kg). It is designed to operate across a broad range of compressed air pressures, typically from approximately 60 to 250 psi, with airflow requirements that vary by application and configuration. Dry ice consumption can reach up to about 425 lbs per hour. The system includes adjustable blast pressure and pellet feed controls and is designed to integrate with standard industrial air supplies using a 1-inch JIC compressed air connection.
Before operation, operators verify that the dry ice supply, air compressor, hoses, and nozzle connections are properly set up and secured. Appropriate personal protective equipment (PPE), including gloves, eye protection, and hearing protection, should be worn, and adequate ventilation should be ensured to manage carbon dioxide gas during use. During blasting, dry ice pellets are metered into the compressed air stream and directed through the nozzle toward the target surface. Upon contact, the pellets sublimate and help dislodge contaminants without leaving blasting media residue. After cleaning, the system is depressurized and cleared according to manufacturer guidelines.
Nu-Ice® dry ice blasting equipment is used across a range of industrial and commercial environments where non-abrasive, dry cleaning is required. Applications include cleaning molds, tooling, presses, and production equipment in manufacturing settings; maintenance of conveyors, ovens, and packaging machinery in food processing facilities; and careful surface cleaning in restoration projects involving brick, stone, or sensitive materials. Additional uses extend to automotive, aerospace, and electrical environments where moisture, abrasive media, or chemical cleaners may be unsuitable.
Dry ice blasting with Nu-Ice® systems produces no secondary blasting waste, as the dry ice pellets sublimate on contact and leave only the removed contaminants behind. The process is non-abrasive, which helps preserve the condition of sensitive surfaces such as electrical components, coated metals, and precision tooling. Because it is a dry, chemical-free method, it is well suited for environments where the introduction of water or solvents is not appropriate. Operators should account for proper ventilation and safe handling of compressed air and carbon dioxide during operation, following standard safety guidelines for industrial blasting equipment.
