Understanding Dry Ice Cleaning Systems: Components & Use
Industrial facilities face constant challenges in maintaining clean, efficient operations—especially when dealing with residue buildup, sensitive surfaces, and costly downtime. As a leading manufacturer of industrial dry ice blasting equipment, Nu-Ice® Dry Ice Blasting provides a non-abrasive, moisture-free solution that avoids the risks of chemical or water-based cleaning methods. A dry ice cleaning system like the Commando® 55TM offers a powerful alternative, combining key components—air supply, hopper, pellet metering, hoses, gun, and nozzles—into a cohesive machine designed to clean thoroughly without surface damage or disassembly.
Dry ice blasting is a non-abrasive, non-conductive cleaning process that uses compressed air to propel dry ice pellets toward a target surface at high velocity. The pellets are composed of solid carbon dioxide (CO₂) and are used specifically for their ability to remove contaminants without mechanically wearing down the underlying material. When the pellets strike a surface, they loosen residues through a combination of kinetic energy and extreme cold. Upon contact, the dry ice sublimates—transitioning directly from a solid to a gas—which creates a rapid temperature differential that weakens the bond between contaminants and the surface. This phase change also contributes to lifting residues away without spreading debris. Because dry ice does not melt into liquid, the process generates no secondary waste such as water, grit, or chemical runoff. These characteristics make dry ice blasting well suited for use in sensitive environments, including industrial equipment, electrical components, and facilities where moisture or chemical exposure must be avoided.
Kinetic Impact
Dry ice pellets are propelled at high velocity by compressed air. The mechanical energy from this impact helps break the bond between the contaminant and the surface, allowing for effective removal.
Thermal Shock
The extreme cold of dry ice causes rapid cooling of the contaminant layer. This temperature differential creates stress at the interface, weakening the bond and promoting separation from the substrate.
Sublimation Expansion
As dry ice changes directly from a solid to a gas upon impact, it expands rapidly—up to 800 times its volume. This expansion helps lift loosened particles away from the surface, enhancing the overall cleaning efficiency without leaving residue.
A dry ice blasting system consists of several key components that work in unison. The air compressor supplies high-pressure air necessary to accelerate the pellets. The dry ice hopper stores and conditions the pellets before use. A metering system controls the pellet flow, ensuring consistent delivery. Hoses transport the air and pellets to the blasting gun, which directs the stream. The nozzle then focuses the output for precise cleaning. Together, these elements support a controlled and efficient cleaning process across various industrial environments.
Nu-Ice Dry Ice Blasting., the company behind Nu-Ice® Dry Ice Blasting, was founded in 2008 and specializes in the design and production of industrial dry ice blasting equipment. All Nu-Ice machines are manufactured in the United States, with a focus on delivering reliable, well-engineered systems for industrial cleaning needs. The company offers a line of dry ice cleaning machines that integrate essential components into a cohesive system designed for ease of use, durability, and effective operation across a range of industries. Its signature equipment, such as the Commando® 55TM, exemplifies this approach.
Nu-Ice dry ice blasting machines are equipped with a lightweight blasting gun designed for ease of handling and precision. Users can choose from various interchangeable nozzles, allowing adjustment based on cleaning requirements. Each system includes an integrated moisture separator to remove condensation from the air stream, which helps protect dry ice pellets from premature sublimation. An aftercooler is also included to reduce the air temperature before it reaches the hopper, maintaining optimal blasting performance. These features support a reliable, controlled operation in challenging environments, including manufacturing facilities and food processing plants.
The Commando® 55TM dry ice blaster is designed with practical dimensions suited for industrial mobility. The machine measures 35 inches long, 20 inches wide, and 40 inches high, with a total weight of 210 pounds. It includes a 55-pound dry ice hopper for extended operation and supports an air flow range between 100 and 165 CFM. Operating pressure ranges from 60 to 150 PSI, accommodating a variety of cleaning scenarios. Dry ice consumption is adjustable, ranging from 0 to 5 pounds per minute, enabling operators to tailor usage to specific job requirements while minimizing waste.
Preparation and Setup: Before operation, users connect the air compressor to the machine, fill the hopper with dry ice pellets, and select the appropriate nozzle for the task. The system’s moisture separator and aftercooler are checked to ensure optimal air quality.
Safety Requirements: Operators wear appropriate personal protective equipment (PPE), including gloves, eye protection, and hearing protection. The blasting area is inspected to confirm proper ventilation and clearance.
Typical Workflow Steps: Once setup is complete, the operator activates the air flow and begins blasting in controlled passes. Adjustments to pressure and pellet feed can be made to suit different surfaces. The process continues until the target area has been uniformly treated, after which the system is powered down and residual dry ice is allowed to sublimate.
Nu-Ice dry ice blasting equipment is used across a broad range of industrial and commercial environments where effective cleaning must be performed without compromising surface integrity or operational efficiency. In manufacturing and production facilities, the equipment is commonly applied to clean heavy machinery, molds, tooling, and conveyor systems directly in place, reducing the need for disassembly and minimizing downtime. Food processing facilities use dry ice blasting to clean ovens, mixers, conveyors, and packaging lines, benefiting from the dry, non-toxic process that does not introduce moisture or chemical residues into controlled sanitation environments. In historical restoration projects, the non-abrasive nature of dry ice blasting makes it suitable for preserving delicate materials such as stone, brick, wood, and decorative architectural features without altering surface finishes. The technology is also widely used in automotive and aerospace maintenance, where precision cleaning is required for engines, molds, composite components, and manufacturing fixtures. Additional applications include electrical and specialty cleaning tasks involving switchgear, turbines, motors, and power distribution components, where moisture-free and residue-free cleaning is essential.
Dry ice blasting generates no secondary waste, as the solid CO₂ pellets sublimate directly into gas upon impact. This eliminates the need for waste recovery associated with water, solvents, or abrasive media. The non-abrasive interaction reduces the risk of surface wear, etching, or dimensional change, making the process suitable for sensitive equipment and coated surfaces. Because the method is entirely dry, it is particularly advantageous in moisture-sensitive environments and around electrical systems. From an operational standpoint, proper ventilation and handling procedures are required due to the extreme cold of dry ice and the release of carbon dioxide gas during sublimation. As part of a complete dry ice cleaning system, Nu-Ice equipment is designed to support consistent performance while reducing reliance on chemical-based or abrasive cleaning methods commonly used in industrial maintenance.
Nu-Ice dry ice blasting systems offer a selection of nozzles and hose configurations to accommodate various cleaning tasks and surface conditions. The interchangeable nozzles are designed for different spray patterns and flow rates. Systems are supported by compatible air supply equipment, including aftercoolers to maintain consistent air temperature. Proper storage of dry ice and regular maintenance of the blasting equipment—such as inspecting seals, hoses, and gun components—are essential for optimal performance and operational safety. These accessories and support systems allow flexible integration into a range of industrial setups.
