Cleaning with the dry ice method does Flashovers can occur in electrical equipment due to a build up of not leave CO2 and moisture particles trapped inside your carpet contaminants, such as dust, grime and product. This can result in fibers as they vaporize and fade away in a matter of minutes. catastrophic failure and significant production downtime. However, in the unfortunate event of a flashover occurring, replacement of equipment is not Dry cleaning allows you to use your carpets immediately after the only option. Dry Ice Cleaning removes contaminants created during the cleaning process is complete. flashover from the equipment, restoring the distribution boards and If you’re dry cleaning an office, it doesn’t interrupt business switchgear back to efficiency. Cleaning with Dry Ice rather than replacing operations and takes less time to perform than other methods. equipment reduces financial costs significantly. Dry Ice Cleaning process is non-conductive and moisture free, and therefore Dry cleaning makes for extremely clean rugs and carpets. The ideal and safe for use on sensitive electrical components. chemicals used to dry clean surfaces pull apart most stains, Effectively removes contaminants post-flashover including stubborn ones that cannot be removed by other Restores electrical equipment to efficiency post flashover methods.

Dry Ice Cleaning in Medical Industry Dry ice blasting for medical and pharmaceutical facilities is a non-abrasive process that will not damage molds or tooling. It allows for more frequent and effective cleaning, which significantly reduces replacement tooling costs and product scrap rates while increasing quality output. Due to its safety, high efficiency, strong cleaning power, and no pollution, dry ice blasting machines are more and more prominent in the medical industry Dry ice blasting process uses small dry ice pellets that are moisture- free, non-conductive, non-corrosive, and non-flammable. Dry ice blasting helps in carefully maintenance of Tools and Ventilation Systems in Hospitals which is critical for postoperative therapy of patients and helps in removing a number of pathogenic microorganisms from surfaces Clinic Cleaning Using Dry Ice
