AUTOOL HTS709

Product Overview

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.

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/cm², making it suitable for users who need professional cleaning performance and accurate pressure monitoring.

Power And Socket

The machine does not run on single phase. The socket must be connected with an earth wire for safe operation.

Hose And Nozzle

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.

Shipping And Return Note

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.

Key Features

Key Features

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.

No Disassembly

Dry ice cleaning can remove carbon deposits without unnecessary engine disassembly, helping reduce service time.

Physical Carbon Removal

Compared with hydrogen-oxygen machine cleaning, dry ice cleaning is a physical process and avoids potential impact on sensitive parts such as catalytic converters.

No Abrasive Residue

Unlike walnut blaster cleaning, dry ice blasting avoids abrasive particle wear and media residue because dry ice sublimates after impact.

Eco-Friendly Cleaning

The process is non-toxic, harmless, chemical-free, water-free, and does not create a secondary waste stream.

How It Works

How It Works

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 CO₂ expansion.

Impact

Compressed air accelerates soft dry ice particles through specially designed nozzles, creating the kinetic force needed to loosen contaminants.

Cold Shock

Dry ice at about -78.5°C / -78.9°C makes carbon deposits, oil residue, and contaminants brittle, helping break the bond between the contaminant and surface.

Expansion

Dry ice sublimates instantly on impact and expands nearly 800 times in volume, creating a micro-explosion effect that removes surface contaminants.

    I have a direct injection motor with 93k miles and the valves were caked with deposits. After a quick clean up of the bulk of the crusty mess, this blaster made quick work of making the valves look like new. Huge improvement in throttle response.

  10. Koua yang

    This Dry Ice Cleaning Machine Works Perfectly!!! I bought this machine to remove the carbon build up on the intake valves from a 2015 Mustang Ecoboost 2.3L engine. I watched a lot of videos trying to decide how I was going to clean the valves. I saw that there were less expensive options by buying pressure blasters, gravity feed blasters, cleaning the valves by manually scraping them with screw drivers or even using a bunch of tie straps on a drill. In the end, I chose this machine because it is all contained into one unit and the videos showed how well it cleans the valves. I am completely satisfied with this unit.

    Came with everything you needs. Works awesome. Very little mess. If you have a shop it’s an instant money maker. You still will have to use a pick just to save some time if the valves are real bad. Even a home shop over time will save money you’re handy.

    Today I used the HTS709 dry ice cleaning machine to clean the combustion chamber, and the effect was very good. I will continue to buy one for my other workshop. This one has a dual pressure gauge, I like it very much

    I believe a dual pressure dry ice machine is better, I used to have an HTS705 but it was smaller and now I’m opening a new workshop.
    I will still go with AUTOOL products! The quality is good! It won’t clean rust but it will clean grease, mud stains

  15. Benjamin Hochhold

    I have used dry ice cleaning machines from other brands before, but the spray force was not enough, and the adjustment was troublesome and easy to clog. But after changing to AUTOOL HTS709, the experience is completely different!
    HTS709 has stronger spray pressure and can easily remove stubborn stains in the engine compartment, chassis, interior and other parts. It supports adjusting the amount of dry ice particles and the spray speed to adapt to the cleaning of different materials, making cleaning more efficient and safer. It is also equipped with an intelligent panel, which is intuitive to operate and saves tedious setting time.
    What satisfies me most is its three-year warranty and remote technical support, which are almost unavailable in products of the same price, and are very suitable for professional stores. In short, AUTOOL HTS709 is the most cost-effective dry ice cleaning machine I have used so far, no one!

    An excellent cleaning tool¡ªI discovered it works not only for cleaning car engines but also for cleaning circuit boards. I used it to clean circuit boards with outstanding results. Setting it to level 5 cleans them thoroughly without damaging any components. It’s incredibly effective, and I’ve uncovered a whole new application for dry ice cleaning!

    The cleaning effect is excellent, with a very high carbon removal capacity. I also use it to quickly clean car chassis. Although it requires a high-performance air compressor, it’s definitely worth getting this machine.

  19. Giancarlo Mazzoni

    Cleaning carbon deposits from an engine typically requires about 15kg of dry ice. This machine uses significantly less dry ice than other models. Its 1100W power is sufficient and highly efficient, making it a highly recommended choice.
