Dry Ice Cleaning/CO2 Cleaning:

» Effective, Efficient and time saving cleaning of Electrical apparatus like 

Motors, Generators etc. 

» Dry Ice Cleaning or CO2 cleaning is a process where dry Ice (Solid form of carbon dioxide) is accelerated in a pressurized air stream and directed at a surface in order to clean it. 

Advantages of Dry Ice/CO2 Cleaning:

» It is a non-abrasive 

» It is Non-conductive cleaning method 

» Does not leave secondary contaminants such as dangerous solvents as dry ice sublimates at room temperature. 

» Saves downtime as the process is less time-consuming. 

Note: For Motors and Generators, our expertise does not stop at cleaning; we complete the job by applying right combinations of varnishes, resins and drying at appropriate temperatures.
