Dry ice generator for cleaning any surface with a stream of fine particles. This device completely removes soot, oil film, dirt, rust. The generator is equipped with a microcomputer, which accurately doses the amount of dry ice and supply pressure. Thanks to the adjustable flow rate, the device gently cleans even those surfaces that cannot be cleaned in any other way. However, the most important feature of the device is its ability to clean the inner walls of the engine without disassembling the motor. To accomplish this, it is enough to warm up the car to operating temperature, turn off the engine, unscrew the plugs and you can start cleaning. Generated ice particles instantly melt in the air after cleaning, and all the sludge is removed from the engine through the exhaust system. Surely such a tool will be useful for both service centers and ordinary craftsmen who like to fix cars themselves.
