Dry Ice Blasting Equipment for Power Generation
Reduce Downtime and Prevent Equipment Failures with Non-Conductive Dry Ice Blasting
Safe and Efficient Cleaning Across Gas, Hydro, Nuclear, Coal, and Substation Infrastructure
Cold Jet dry ice blasting delivers exceptional cleaning results for utilities, independent power producers (IPPs), and power plant operators across all power generation sectors. By replacing water-based cleaning, abrasive methods, and time-consuming manual cleaning with a dry, non-conductive solution, power generation operators achieve:
- Up to 90% Faster Cleaning: Dramatically reduce outage time across all power generation sectors—turbines, generators, HRSG systems, and substations cleaned in a fraction of the time required by traditional methods.
- Significantly Improve Electrical Performance: Restore insulation resistance by 600% on average, with improvements up to 1,000% documented. Polarization indices improve from critical levels (1.04) to acceptable range (2.30).
- Safe for Electrical Equipment: Non-conductive, moisture-free cleaning enables safe maintenance of switchgear, control cabinets, transformers, and high-voltage substations.
- Zero Secondary Waste: Dry ice sublimates completely upon impact, eliminating water disposal and hazardous waste handling. With no drying time required, components can be returned to service immediately.
- Clean In-Place: Eliminate equipment disassembly—clean while components remain installed and reach areas inaccessible to traditional methods.

What are the Benefits of Dry Ice Blasting for Power Generation?
Optimize Asset Performance and Minimize Scheduled Outages
Dry ice blasting provides a non-conductive, non-abrasive, zero-waste cleaning solution that removes heavy fouling, carbon buildup, grease, surface oxidation, and corrosive salts without damaging sensitive assets. By eliminating secondary waste and drying time, it allows for immediate inspection and a faster return to service.
Traditional cleaning methods—such as chemical solvents, high-pressure washing, and abrasive blasting—introduce significant operational risks. These processes can lead to moisture-induced corrosion, grit entrapment in precision components, and the degradation of delicate insulation. They also generate vast amounts of secondary waste, turning a routine maintenance task into a costly logistical and environmental challenge.
Cold Jet dry ice blasting eliminates these problems and provides the following benefits for power generation facilities:
-
Dramatic Reduction in Outage Time
Dry ice blasting removes carbon buildup, fouling, and surface oxidation from critical assets—including gas turbines, generators, HRSG tube bundles, and electrical systems. Operators report cleaning time reductions of up to 90% compared to traditional methods. In one instance, a power producer completed the cleaning of an 8-megawatt turbine in just four hours, a task that previously required five days of manual labor. This massive reduction in downtime helps utilities meet aggressive outage schedules and maximize plant availability.
-
Restores Thermal Efficiency and Equipment Performance
Dry ice blasting optimizes heat transfer by removing insulating deposits from finned surfaces and internal cooling passages. Power producers have documented a 12% improvement in power output following dry ice cleaning, compared to just 4% with traditional methods. By penetrating deep into dense tube banks to eliminate bridging, the process reduces differential pressure and lowers fuel consumption, directly improving the plant’s overall heat rate and bottom line.
-
Safe Around Electrical Equipment
Dry ice cleaning is non-conductive, making it safe for cleaning substations, generator windings, motor stators, transformers, and control systems without risk of electrical shorts or equipment damage. Utilities document insulation resistance improvements averaging 600% with some generators showing 1,000% increases. The moisture-free process prevents electrical tracking in windings and eliminates leakage currents that lead to flashovers and unplanned outages.
-
Protects Equipment from Damage
Cold Jet dry ice blasting is non-abrasive and eliminates the risk of surface erosion or pitting on precision-machined components. Unlike grit blasting, which can alter critical tolerances, or pressure washing, which risks moisture-induced corrosion, dry ice removes stubborn contaminants while preserving the original substrate. This allows for the safe cleaning of delicate winding insulation and turbine blade profiles without the removal of base material.
-
Eliminates Secondary Waste
Dry ice sublimates completely upon impact, leaving zero secondary waste. This eliminates the cost and complexity of reclaiming contaminated water, disposing of spent abrasive media, or managing hazardous chemical runoff. While this is a critical advantage for nuclear facilities looking to minimize radioactive waste volumes, it also provides massive logistical savings for fossil and hydro plants.
Dry Ice Blasting Applications for Power Generation
Cold Jet dry ice blasting equipment provides cleaning and maintenance solutions across five primary power generation sectors:
-
Natural Gas Power Plants
-
Hydroelectric Facilities
-
Nuclear Power Generation
-

Dry ice blasting maximizes plant availability by restoring critical components to peak thermal efficiency without the wear caused by traditional abrasives. By eliminating secondary waste, facilities can streamline maintenance schedules and return units to operation faster.
-
Gas Turbine Systems
Dry ice blasting removes carbon deposits, oils, and particulate matter from blades, combustion chambers, and compressor sections. The process cleans turbines in-place without full disassembly. Power producers have reported reducing turbine cleaning time by 90%—an 8-megawatt turbine was cleaned in four hours with dry ice cleaning versus five days when using manual methods.
-
Heat Recovery Steam Generators (HRSG)
Cold Jet dry ice blasting removes ammonia salts (Ammonium Bisulfate), sulfur deposits, insulation, iron oxide, and fouling from tube bundles without damaging tube bundle welds. Dry ice cleaning reaches between closely-spaced tube fins and restores heat transfer efficiency. Facilities report 40% faster cleaning compared to competitive methods, with power output improvements of 12% versus 4% with traditional methods.
-
Compressors & Auxiliary Systems
Dry ice blasting cleans rotating equipment, starting motors, alternators, and auxiliary systems without disassembly. The process removes oils, carbon, and debris that accumulate on these components, maintaining equipment reliability while minimizing downtime.
Dry ice blasting cleans the following equipment in natural gas power plants:

-
Generator Stators and Windings
Cold Jet dry ice blasting safely cleans all generator components—from delicate windings to stubborn contamination on cast iron housings. Utilities document insulation resistance improvements averaging 600%, with some generators showing 1,000% improvements. Polarization indices improved from critical levels (1.04) to acceptable range (2.30). A hydroelectric plant restored a generator considered ‘beyond salvage’ and returned it to full service in just six days using dry ice blasting.
-

Dry ice sublimates completely upon impact, producing zero secondary waste—a critical advantage in nuclear environments where disposing of contaminated water or abrasive media often costs more than the cleaning itself.
-
Operating Facility Maintenance
Dry ice blasting maintains heat exchangers, steam generators, turbines, pumps, electrical components, and ventilation systems without generating contaminated water or spent media requiring disposal as radioactive waste. The process effectively removes radioactive contamination ranging from Class A through Class C, removes buildup and surface contamination without damaging sensitive components, and reduces radiation exposure time for maintenance personnel.
-
Decommissioning & Decontamination
Cold Jet dry ice blasting removes radioactive contamination from walls, floors, hot cells, gloveboxes, equipment, and ductwork. The process minimizes waste volume by 90% or more compared to abrasive blasting, significantly reducing disposal costs.
