Industrial environments often face persistent challenges from grease, oil, and residue buildup, particularly in areas with sensitive components where downtime and surface protection are critical. Traditional cleaning methods—such as water, chemicals, or abrasive techniques—can introduce risks to electrical systems and require partial disassembly. As an alternative, dry ice engine cleaning offers a non-conductive, moisture-free solution that helps preserve delicate components. Nu-Ice Blasting™ designs and manufactures advanced dry ice blasting equipment, including the Commando 35, engineered to support precise cleaning applications. This approach enables effective dry ice engine bay detailing and safe engine cleaning dry ice processes without introducing secondary waste or compromising electrical integrity.
Dry ice blasting is a cleaning method that uses solid carbon dioxide (CO₂) pellets accelerated by compressed air to remove contaminants from surfaces. The process involves directing dry ice particles at high speed toward a target area, where they impact and loosen unwanted residues such as grease, oil, or dirt. Upon contact, the dry ice pellets rapidly sublimate—transitioning from solid to gas—without leaving behind liquid or additional waste. This absence of secondary waste reduces cleanup requirements and eliminates moisture-related risks. The system relies on controlled airflow and pellet delivery to ensure consistent and precise cleaning across a range of industrial applications.
Kinetic Impact
Dry ice pellets are propelled at high velocity using compressed air. When they strike a surface, the impact helps break the bond between contaminants and the underlying material.
Thermal Shock
The extremely low temperature of dry ice creates a rapid temperature difference upon contact. This causes contaminants to contract and become brittle, weakening their adhesion to the surface.
Sublimation Expansion
As the dry ice pellets sublimate instantly into gas, they expand in volume. This expansion lifts and dislodges loosened contaminants, leaving the surface clean without generating secondary residue.
A dry ice blasting system consists of several key components that work together to deliver consistent cleaning performance. An air compressor supplies the pressurized air required to propel dry ice pellets. The dry ice hopper stores and feeds the pellets into the system, maintaining a steady supply during operation. A metering system regulates the flow rate of pellets, allowing operators to adjust cleaning intensity based on the application. The hose transports the combined air and dry ice mixture from the machine to the point of use, while the nozzle directs and focuses the stream onto the target surface. Together, these components enable controlled and efficient cleaning processes.

Founded with an emphasis on engineering and manufacturing in the United States, the company produces equipment intended to support efficient and non-abrasive cleaning across various industries. Its product range includes machines such as the Commando 35, which are built to deliver controlled dry ice pellet flow and consistent performance. By utilizing dry ice as a cleaning medium, Nu-Ice Blasting™ equipment enables processes like dry ice engine bay detailing while avoiding the use of water or chemical agents. The company’s approach centers on providing equipment solutions that support operational efficiency, reduced downtime, and effective contaminant removal without generating secondary waste.
Nu-Ice Blasting™ equipment incorporates a range of functional features designed to support controlled dry ice cleaning operations. The blasting gun serves as the primary interface for directing dry ice pellets, allowing operators to manage the flow and targeting of the cleaning stream. Interchangeable nozzle options are available to adjust the shape and focus of the blast pattern, enabling adaptation to different surface geometries and access requirements. Systems may also include integrated moisture separators, which remove water from the compressed air supply before it enters the machine, helping maintain dry operating conditions. In addition, aftercoolers are used to reduce the temperature of compressed air, contributing to consistent airflow performance. These components work together to support stable pellet delivery and system operation.
Nu-Ice Blasting™ equipment is designed with specifications suited for industrial cleaning environments. Machines are constructed with compact but durable dimensions to allow for mobility and integration into various workspaces. Unit weight varies by model but is configured to balance portability with structural stability. Hopper capacity is designed to hold a practical volume of dry ice pellets, supporting continuous operation before refilling is required. Air flow requirements typically fall within a defined range to ensure sufficient propulsion of pellets, while operating pressure levels are adjustable to accommodate different cleaning intensities. Dry ice consumption rates depend on the selected settings and application demands, with metering systems regulating pellet usage. These technical parameters enable operators to align equipment performance with specific operational needs.
Preparation and Setup
The process begins with connecting the equipment to a suitable air compressor and ensuring a clean, dry air supply. Dry ice pellets are loaded into the hopper, and system settings such as air pressure and pellet feed rate are configured.
Safety Requirements
Operators follow standard safety procedures, including the use of protective equipment and ensuring adequate ventilation. Equipment checks are conducted prior to operation to confirm proper connections and system readiness.
Typical Workflow Steps
Once activated, compressed air propels dry ice pellets through the hose and nozzle toward the target surface. The operator controls the blasting pattern and intensity using the gun and metering system. After completion, the system is shut down, and remaining dry ice is managed according to handling guidelines.
Nu-Ice Blasting™ equipment is used across a range of industrial and commercial environments where controlled surface cleaning is required. In manufacturing and production settings, the equipment is applied to remove buildup from machinery, molds, and production lines without introducing moisture. Within food processing and sanitation environments, dry ice blasting systems are used on equipment and surfaces where dry cleaning methods are preferred. The technology is also utilized in historical restoration projects, where delicate surfaces such as wood, stone, or artifacts require careful treatment.
In automotive and aerospace sectors, equipment is applied to clean components, assemblies, and engine areas, including applications involving electrical systems. Electrical and specialty cleaning environments benefit from the dry, non-conductive nature of the process. Additionally, dry ice blasting equipment is used in industries such as printing, plastics, and power generation, where residue removal and surface preparation are part of routine maintenance operations. These applications reflect the versatility of equipment across multiple sectors.
Dry ice blasting is characterized by a process that does not generate secondary waste, as dry ice sublimates into gas upon impact. The method is non-abrasive, allowing surfaces to be cleaned without mechanical wear when operated within appropriate parameters. Because the process is dry and does not rely on chemical agents, it avoids introducing moisture or residues into sensitive environments. These characteristics support applications such as safe engine cleaning dry ice, particularly in areas where electrical components are present. Operational considerations include ensuring proper ventilation due to CO₂ release and maintaining a consistent supply of dry ice pellets. Equipment setup and air quality management also play important roles in maintaining stable performance.
Nu-Ice Blasting™ systems can be configured with a range of accessories to support different operational requirements. Nozzle and hose options allow operators to adjust reach, flexibility, and blast pattern depending on the application. Air supply components, including compatible compressors and aftercoolers, are used to maintain consistent airflow and reduce moisture in the system. Proper integration of these elements supports stable equipment performance. Storage considerations include maintaining dry ice in appropriate insulated containers to minimize sublimation, while routine maintenance involves checking hoses, fittings, and air quality to ensure reliable operation over time.
