AUTOOL HTS708 Dry Ice Blasting Cleaning Machine is a professional-grade cleaning solution engineered for the automotive repair and service industry, specifically designed for efficient engine carbon deposit removal. By accelerating dry ice particles with high-speed compressed air, the HTS708 rapidly dislodges and removes stubborn carbon buildup without damaging engine components.

During the cleaning process, dry ice sublimates instantly after impact, leaving no secondary waste, no moisture, and no chemical residue—ensuring a clean, environmentally friendly operation. The HTS708 is ideal for carbon cleaning in critical areas such as the engine bay, combustion chambers, intake valves, throttle bodies, and vehicle underbody. Most cleaning tasks can be completed in as little as 15 minutes, with no disassembly required, significantly reducing labor time and improving workshop efficiency.

Why Choose the AUTOOL HTS708 Dry Ice Cleaning Machine?

Dry ice cleaning offers clear advantages over traditional carbon removal methods, such as chemical solvents, hydrogen-oxygen machines, and walnut blasting, making the HTS708 a safer, faster, and more professional solution.

First, no engine disassembly is required, which significantly reduces labor time and eliminates the risk of installation errors. Second, unlike hydrogen-oxygen cleaning, which relies on chemical reactions, dry ice cleaning is a purely physical carbon removal process, ensuring sensitive components such as catalytic converters, oxygen sensors, and intake systems remain completely unharmed.

Compared with walnut blasting, the HTS708 avoids abrasive contact altogether. No media wear, no residual particles, and no component erosion—protecting engine parts while delivering thorough cleaning results.

During operation, high-pressure air propels -78.5°C dry ice particles onto carbon deposits, causing rapid thermal shock and micro-explosions that break carbon into fine powder. The dry ice then sublimates instantly, lifting contaminants away and expelling them with compressed air. The entire process is non-toxic, chemical-free, residue-free, and environmentally friendly, with no secondary pollution or cleanup required.

Differences between different dry ice machine models

The AUTOOL HTS705, HTS708, and HTS709 dry ice blasting machines are designed to meet different professional cleaning needs. The HTS705 is a compact, entry-level model focused on portability and cost efficiency, making it ideal for individual users or small workshops with light cleaning demands. The HTS708 serves as the core professional model, offering increased dry ice capacity and a robust industrial design to support stable, continuous operation in daily workshop use. The HTS709, as the flagship version, features dual pressure gauges for more precise control, making it best suited for complex, high-precision cleaning tasks and sensitive components.

Warm tips:

• Recommend using preferably 3 mm dry ice pellets and up to 8 mm dry ice pellets.
• The machine requires 90 PSI or more for proper operation.
• Suggest to use a 1.5m³/min compressor with a 300L air tank to supply the air pressure and store air pressure in the air tank (It would be better if your air compressor has a dehumidification function, which can effectively prevent dry ice from becoming clumped together).
• The machine doesn’t run on a single phase. The socket must to connect with the earth wire.
• The blasting hose is 3m.
• Machie’s operating power is more than 1.5m³/min.
• The connection of the air inlet is a female 4-part (1/2) thread with an inner diameter of about 19mm.
• Nozzle sizes are available in 5mm and 6mm.
• We can customize a longer hose for you if needed; the longest hose is 5m. You need to pay extra fees for it. Please contact us for more details.
• Different countries have different tariff policies—some impose tariffs, while others do not. The good news is that HTS708 shipments from China to the US can be tariff-free, and tariffs for shipping to other countries can also be reduced.
• Because AUTOOL HTS708 has a relatively high shipping cost and also needs to pay certain customs duties, so it does not support returns. Please be sure to contact us if there is any problem with the HTS705 or if you have any questions. We will ensure that we solve your problems effectively, provide you with the best customer service, and make you 100 percent happy with your purchase. Thanks 🙂
