AUTOOL HTS709
Dry ice cleaning is a non-invasive cleaning method that uses compressed air to propel dry ice particles onto dirt, oil, and carbon deposits. Because dry ice sublimates directly into CO2, it leaves no water residue and reduces secondary cleanup compared with many traditional cleaning methods. The AUTOOL HTS709 dry ice blaster is designed for automotive maintenance and wider industrial cleaning scenarios. This guide explains how dry ice blasting works, why it is useful for car care, and which HTS709 features matter most for repair shops in 2025.
Working Principle

The basic working principle of a dry ice blaster

1. Dry Ice Blasting Cleans Through Impact, Temperature Shock, and Sublimation

A dry ice blaster machine uses compressed air to propel dry ice particles onto a surface. The cleaning process depends on three connected effects: high-speed impact, rapid cooling, and CO2 sublimation.

High velocity impact and heat transfer

High-pressure airflow drives dry ice particles toward the surface. When the particles hit the dirt layer, they rapidly vaporize, causing intense heat transfer and instant CO2 sublimation.

Freeze embrittlement and cracking

Dry ice is about -78.5°C. The low temperature cools dirt quickly and makes it brittle. Differences in thermal expansion create tiny cracks that weaken the bond between dirt and the surface.

Micro-explosive stripping and removal

Dry ice particles enter the cracks and expand rapidly as they sublime. This expansion can reach about 800 times the original volume, creating a micro-explosive stripping effect that separates dirt from the surface.

After sublimation, the CO2 volatilizes directly and the main material left behind is removed dirt residue. This means there is no secondary pollution from the cleaning medium, and it reduces wastewater, chemical residue, and follow-up cleanup work.

Car Maintenance Value

2. Dry Ice Cleaning Is Efficient, Waterless, and Gentle on Delicate Parts

Dry ice cleaning is valuable in automotive maintenance because it combines cleaning efficiency with a waterless and non-corrosive process. It can remove carbon deposits, oil, and dust while reducing the need for disassembly in many service scenarios.

  • Efficiency and eco-friendlinessDry ice cleaning can remove carbon deposits and improve maintenance efficiency. By helping clean deposits that affect combustion and airflow, it can support engine performance and fuel efficiency maintenance.
  • Protection for delicate partsThe process is waterless and non-corrosive, making it useful around electronics, seals, circuits, engines, and transmissions when the correct method is used.
  • Environmental benefitsIt leaves no wastewater or residue from the cleaning medium, helping reduce pollution and cleanup workload.
  • Wide range of applicationsDry ice cleaning can be used on engines, brakes, interiors, chassis areas, and other automotive components where controlled non-invasive cleaning is useful.

3. HTS709 Focuses on Precise Control, Stable Ice Delivery, and Continuous Operation

The AUTOOL HTS709 is a dry ice blaster machine developed for car care and other industries. Its main advantages come from high-efficiency cleaning, precise control, stable operation, and design features that help reduce clogging and downtime.

Precise operation

The dual pressure gauge design includes input and output pressure gauges, helping operators keep the cleaning process safer, more controllable, and more precise.

Intelligent control panel

The built-in microcomputer control system can adjust pressure and dry ice conveying speed so the cleaning process can be matched to the surface and dirt condition.

Efficient cleaning without disassembly

High-pressure dry ice blasting can remove carbon and oil from the throttle, intake valve, engine parts, combustion chamber, and other components without disassembling every part.

Short cleaning time

The original article notes that a deep cleaning job can be completed in about 15 minutes, improving maintenance efficiency when the application is suitable.

Anti-clogging technology

Spiral dry ice separation technology uses an innovative mixing system to prevent dry ice from sticking and clumping, helping maintain stable dry ice pellet delivery and reducing pipe clogging.

Oil-water separation

The large-diameter oil-water separator helps prevent water from entering the dry ice system, reducing dry ice clumping, pipeline blockage, and water accumulation inside the equipment.

4. HTS709 Supports Engine, Intake, Chassis, Suspension, and Industrial Cleaning

The HTS709 includes a 7.5 kg large-capacity ice storage bin, which extends continuous cleaning time and reduces frequent refilling. A push-pull handle and 360° universal wheels make it easier to move in different cleaning scenarios.

  • Engine compartment cleaningRemoves carbon, oil, and dust in high-temperature engine areas to help reduce buildup that can affect performance.
  • Intake system cleaningCleans the throttle, intake valve, turbocharger, and related components to support airflow and fuel economy maintenance.
  • Chassis and suspension cleaningRemoves mud, oil, and anti-rust coating residue to reduce component wear and help prolong service life.
  • Precision and electronic partsBecause the process is waterless and dry, it is suitable for components sensitive to water and chemicals when handled correctly.
  • Industrial applicationsBeyond automotive maintenance, HTS709 can also be used in rubber, casting, shipbuilding, electric power, chemical, printing, plastics, food, pharmaceutical, aviation, and other industries.
