Industrial environments in electronics and aerospace sectors face persistent cleaning challenges—from delicate sensor surfaces to sensitive wiring systems—where residue buildup can lead to costly downtime and damage. Traditional cleaning methods, including wet washes, abrasive scrubbing, or harsh chemicals, often pose risks to intricate equipment. Nu-Ice™ Dry Ice Blasting offers a precision solution: an innovative cryogenic blasting technology designed to clean without water, abrasion, or residue. As a manufacturer of advanced dry ice blasting systems, Nu-Ice™ presents a non-invasive alternative that is ideal for critical applications requiring cleanliness without compromise. Dry ice blasting electronics and dry ice blasting aerospace operations now have a safer, faster, and residue-free option.
Dry ice blasting is a non-abrasive, non-conductive cleaning process that uses solid carbon dioxide (CO₂) pellets accelerated by compressed air to remove contaminants from surfaces. The process relies on high-velocity impact combined with the unique properties of dry ice. Upon contact, the pellets sublimate—transforming directly from solid to gas—eliminating any need for water or abrasive media. This sublimation also means there is no secondary waste, making it ideal for use in sensitive environments where residue and moisture are unacceptable.
Kinetic Impact
Dry ice pellets are propelled at high velocity through a blast nozzle, delivering sufficient energy to fracture and dislodge surface contaminants without damaging the underlying material.
Thermal Shock
The extreme cold of dry ice creates a rapid temperature differential between the contaminant and the substrate, weakening the bond between them and aiding in removal.
Sublimation Expansion
Once the dry ice contacts the surface, it sublimates instantly, expanding in volume. This expansion helps lift contaminants from complex geometries and textured surfaces without abrasion or liquid runoff.
A dry ice blasting system is composed of several essential components that work in concert to deliver precise and effective cleaning. The air compressor generates the compressed air required to accelerate the dry ice pellets. The dry ice hopper stores the solid CO₂ before it is metered into the airflow. The metering system controls the flow of pellets to ensure consistent blasting. Finally, the hose and specialized nozzle deliver the dry ice to the target area, allowing operators to direct the cleaning force with control and precision.

Nu-Ice dry ice blasters are equipped with a lightweight blasting gun engineered for controlled, precise handling during extended cleaning operations. The ergonomic design supports operator comfort while allowing accurate targeting of both broad surfaces and detailed areas. The system includes a selection of interchangeable nozzles that enable users to adjust spray patterns, impact intensity, and coverage based on surface material, geometry, and contamination type. This flexibility allows the same unit to be used for varied cleaning requirements across different industrial environments. Integrated into the system are a moisture separator and an aftercooler, both of which play a critical role in maintaining consistent performance. The moisture separator removes water vapor from the compressed air supply, reducing the risk of ice clumping or blockages, while the aftercooler lowers air temperature before blasting to help preserve dry ice pellet integrity. Together, these components support stable operation and precise user control in applications where dry, non-abrasive cleaning is essential.
The Nu-Ice Commando 55 dry ice blaster is a compact, portable unit designed to support industrial cleaning tasks that require mobility and consistent output. The machine measures approximately 36 inches in height, 18 inches in width, and 30 inches in length, with a total operating weight of 175 pounds, allowing it to be transported and positioned easily within industrial facilities. It features a 55-pound dry ice hopper, supporting extended blasting cycles before refilling is necessary. The system operates within an airflow range of 100 to 225 CFM and accommodates air pressures between 80 and 200 PSI. Typical dry ice consumption ranges from 1.5 to 3.5 pounds per minute, depending on operating settings and application requirements, supporting both light-duty maintenance and more demanding cleaning scenarios.
Preparation and Setup
Before starting, the operator ensures the equipment is connected to a suitable compressed air supply and fills the hopper with dry ice pellets. Proper placement of hoses and nozzle components is confirmed.
Safety Requirements
Operators wear standard personal protective equipment, including gloves, hearing protection, and eye protection. Adequate ventilation is ensured, especially in enclosed spaces, to accommodate CO₂ expansion during sublimation.
Typical Workflow Steps
The system is powered on, and the airflow is adjusted using onboard controls. The operator engages the trigger on the blasting gun and directs the nozzle toward the targeted area, maintaining a safe and steady distance. Blasting continues in controlled passes until the surface is visibly cleaned, after which the equipment is powered down and purged.
Nu-Ice dry ice blasting equipment is used across a wide range of industries due to its dry, residue-free cleaning capability. In manufacturing and production facilities, it aids in the cleaning of molds, presses, and conveyors without halting operations. Food processing environments utilize dry ice blasting to remove organic buildup on machinery while maintaining hygiene standards. In restoration work, the non-abrasive nature of the process makes it suitable for cleaning delicate surfaces such as historic masonry or painted wood. The technology is also applied in the automotive and aerospace sectors to clean engine components, avionics, and airframes without moisture exposure. In the electrical industry, the process is used to remove carbon deposits from energized equipment and insulators. Specialty uses include plastics manufacturing, printing equipment maintenance, and fire damage cleanup.
Dry ice blasting produces no secondary waste, as the CO₂ pellets sublimate on contact—leaving only the dislodged contaminant behind. The process is non-abrasive and does not etch, grind, or wear the cleaned surface, making it safe for delicate equipment. It operates without water or chemicals, reducing cleanup time and lowering the risk of equipment corrosion or residue. Environmental handling of carbon dioxide must be considered, particularly in confined spaces, where CO₂ gas buildup requires adequate ventilation. Overall, cryogenic blasting provides a dry, efficient, and contact-free cleaning method for sensitive or hard-to-reach areas.
Nu-Ice dry ice blasting systems support a variety of accessories designed to improve versatility and operational efficiency. Multiple nozzle options are available to suit different cleaning tasks, including focused and wide-angle applications. Hoses are selected based on required airflow and reach, and must be properly matched to the system’s specifications. Air supply is provided by a compatible compressor and can be paired with an aftercooler to condition the air for optimal pellet performance. For best results, operators store equipment in clean, dry environments and perform routine checks on air filters, seals, and fittings to ensure consistent operation.
