Generally, dry ice pellets used in dry ice cleaning machines are of 3mm size. Therefore, cleaning methods for spaces less than 1mm in size are challenging. 

However, at KMTech, we possess the technology to perform nozzle cleaning at a size of 0.7mm, and based on this capability, we have succeeded in carbon fiber nozzle cleaning. 

With this technological prowess, we have supplied to large corporations and established ourselves as a company equipped with cleaning systems that were previously deemed impossible by other dry ice cleaning machine companies.
