AUTOOL HTS709<\/div>\n

Product Overview<\/h2>\n

The AUTOOL HTS709 is a high-performance dry ice cleaning machine and dry ice blasting equipment with dual pressure display functions, designed for automotive engine carbon cleaning and professional workshop cleaning. It accelerates dry ice particles with high-speed airflow to quickly remove carbon deposits from engine compartments, cylinder combustion chambers, intake valves, throttle valves, vehicle undersides, and related areas. After cleaning, the dry ice rapidly vaporizes into gas, leaving no residue, moisture, or chemical pollution and causing no damage to the vehicle surface when used properly.<\/p>\n

Compared with other AUTOOL dry ice blaster machine models, HTS709 is further optimized and upgraded for uninterrupted operation, stronger reliability, and more precise control. With its new design, it can start working as long as the air pressure is above 4 kg-f\/cm\u00b2, making it suitable for users who need professional cleaning performance and accurate pressure monitoring.<\/p>\n

Before You Order And Use<\/div>\n

Before You Order And Use<\/h2>\n

Review dry ice pellet size, compressor setup, power connection, hose length, nozzle size, shipping, tariff, and return policy before ordering HTS709.<\/p>\n <\/div>\n

\n
\n

Dry Ice Pellets<\/h3>\n

Recommended dry ice pellet size is 3mm. Up to 5mm dry ice pellets are supported.<\/p>\n <\/article>\n

\n

Air Pressure Requirement<\/h3>\n

The machine requires 90 PSI or more for proper operation. The new design can start working when air pressure is above 4 kg-f\/cm\u00b2.<\/p>\n <\/article>\n

\n

Compressor Setup<\/h3>\n

Suggested compressor setup is 1.5m\u00b3\/min with a 300L air tank. A dehumidification function is recommended to prevent dry ice from clumping.<\/p>\n <\/article>\n

\n

Power And Socket<\/h3>\n

The machine does not run on single phase. The socket must be connected with an earth wire for safe operation.<\/p>\n <\/article>\n

\n

Hose And Nozzle<\/h3>\n

The standard blasting hose is 3m. Custom hose length up to 5m is available with extra cost. Nozzle sizes are available in 5mm and 6mm.<\/p>\n <\/article>\n

\n

Shipping And Return Note<\/h3>\n

HTS709 has relatively high shipping cost and may involve customs duties, so returns are not supported. Tariff policy varies by country; contact support before ordering if you have questions.<\/p>\n <\/article>\n <\/div>\n <\/section>\n\n

Key Features<\/div>\n

Key Features<\/h2>\n

Dry ice cleaning offers strong advantages over chemical solvents, hydrogen-oxygen machines, and walnut blasters. It is a physical carbon removal process that does not require engine disassembly, avoids abrasive residue, and leaves no secondary pollution after cleaning.<\/p>\n

\n
\n

No Disassembly<\/h3>\n

Dry ice cleaning can remove carbon deposits without unnecessary engine disassembly, helping reduce service time.<\/p>\n <\/article>\n

\n

Physical Carbon Removal<\/h3>\n

Compared with hydrogen-oxygen machine cleaning, dry ice cleaning is a physical process and avoids potential impact on sensitive parts such as catalytic converters.<\/p>\n <\/article>\n

\n

No Abrasive Residue<\/h3>\n

Unlike walnut blaster cleaning, dry ice blasting avoids abrasive particle wear and media residue because dry ice sublimates after impact.<\/p>\n <\/article>\n

\n

Eco-Friendly Cleaning<\/h3>\n

The process is non-toxic, harmless, chemical-free, water-free, and does not create a secondary waste stream.<\/p>\n <\/article>\n <\/div>\n <\/div>\n

\n
\n
How It Works<\/div>\n

How It Works<\/h2>\n

Dry ice blasting uses compressed air as the power source to accelerate dry ice particles to high speed and blast them onto the contaminated surface. The cleaning effect comes from impact, low-temperature thermal shock, and rapid CO\u2082 expansion.<\/p>\n <\/div>\n

\n
\n

Impact<\/h3>\n

Compressed air accelerates soft dry ice particles through specially designed nozzles, creating the kinetic force needed to loosen contaminants.<\/p>\n <\/article>\n

\n

Cold Shock<\/h3>\n

Dry ice at about -78.5\u00b0C \/ -78.9\u00b0C makes carbon deposits, oil residue, and contaminants brittle, helping break the bond between the contaminant and surface.<\/p>\n <\/article>\n

\n

Expansion<\/h3>\n

Dry ice sublimates instantly on impact and expands nearly 800 times in volume, creating a micro-explosion effect that removes surface contaminants.<\/p>\n <\/article>\n <\/div>\n

\n

Safe And Harmless<\/h3>\n

Dry ice is non-toxic and harmless. It sublimates after impact, leaving no blasting media, water, or chemical residue behind.<\/p>\n <\/article>\n

\n

Exquisite Workshop Design<\/h3>\n

Push handle, control panel, air source interface, dry ice gun interface, and four 360\u00b0 universal wheels make the machine convenient and labor-saving.<\/p>\n <\/article>\n
