Key Features
Dual Pressure Gauges with Anti-Clumping Feed
Inlet and Outlet Pressure Monitoring
Read incoming air pressure and outlet working pressure on separate gauges to monitor the supply and blasting conditions during cleaning.
Moisture and Clumping Control
Use the large oil-water separator and spiral feed to reduce moisture-related dry ice clumping, line blockage and interrupted delivery.
Adjustable Ice Delivery
Increase dry ice output gradually while watching inlet and working pressure, then keep the small-area tested setting appropriate for the approved surface and cleaning task. The machine can begin operation when air pressure is above 4 kg-f/cm².
7.5kg Internal Capacity
The machine can hold up to 7.5kg of dry ice internally, extending continuous operation time and reducing refill frequency.
Match Setup to Job
Match the cleaning setup to the cylinder or intake area being serviced; actual time and dry ice use vary with the job.
Fewer Refills for Repeated Cleaning
Larger capacity reduces refill frequency during repeated workshop cleaning.
Organized Mobile Controls
Push handle, control panel, air source interface, dry ice gun interface, and four 360° universal wheels make the machine convenient and labor-saving. Emergency stop, control panel, gun holder, handle and casters keep operating points accessible.
No Solid Dry-Ice Media Residue
Dry ice sublimates after impact, leaving no solid dry-ice blasting media behind. Collect loosened carbon, oil and other contamination after cleaning.
Physical Cleaning Process
Use dry ice impact, cold shock and sublimation for physical contaminant removal. Select only surfaces and vehicle procedures suitable for the method, including around sensitive components.
Task-Dependent Cleaning Time
The stated cleaning example is about 15 minutes for some engine-carbon tasks. Actual time and required disassembly depend on the vehicle procedure, access, air supply, dry ice, nozzle and contamination; use dry ice on intake valves or combustion chambers only where the exact procedure permits.
Cryogenic Deposit Embrittlement
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.
Near-800× Sublimation Expansion
Dry ice sublimates instantly on impact and expands nearly 800 times in volume, creating a micro-explosion effect that removes surface contaminants.
Compressed-Air Kinetic Cleaning
Compressed air accelerates soft dry ice particles through specially designed nozzles, creating the kinetic force needed to loosen contaminants.
Product Dimensions
The machine measures 635 × 517 × 815 mm.
3 Years Warranty Support
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.

FAQs
Pressure, Pellets, and Ventilation Questions
What is the main HTS709 control difference?
It shows inlet and outlet pressure separately and adds adjustable ice delivery with moisture/anti-clumping support.
What pellet size should I use?
Use 3 mm pellets. Up to 5 mm is supported when the nozzle and setup are confirmed.
What Compressor Does HTS709 Need?
HTS709 requires 90 PSI or more for proper operation. The suggested setup is a 1.5m³/min compressor with a 300L air tank. A compressor with dehumidification function is recommended because it can help prevent dry ice from clumping and reduce moisture-related pipeline problems.
What power supply does it need?
Ask AUTOOL to confirm the voltage, phase, plug and grounding for the selected regional HTS709 unit before ordering.
Does Dry Ice Blasting Leave A Residue?
No. Dry ice sublimates on impact and leaves no blasting media residue, water residue, or chemical residue. This reduces cleanup, secondary waste disposal, and preparation work such as masking delicate sensors or wrapping electronic components.
- It leaves no solid dry-ice media, but removed contamination still needs collection and CO₂ requires ventilation.
Can dual gauges guarantee safe cleaning?
No. Material, coating, nozzle, distance, pressure, airflow and operator procedure still control suitability.
What Is Dry Ice Blasting?
Dry ice blasting, also called dry ice cleaning, is an environmentally sustainable cleaning and surface preparation technique. Like sandblasting, grit blasting, and soda blasting, it uses a pressurized air stream to clean surfaces. Instead of abrasive media, it uses recycled CO₂ pellets that blast at high speed and sublimate on impact to remove dirt and contaminants.
- The process is non-abrasive, non-conductive, non-flammable, non-toxic, chemical-free, water-free, and does not create a secondary waste stream. When dry ice hits the surface, it changes from solid CO₂ to gaseous CO₂.
How Does Dry Ice Blasting Work?
- Impact: Compressed air accelerates soft dry ice through the nozzle.
- Cold: About -109°F / -78.9°C makes contaminants brittle and weakens their bond.
- Expansion: Pellets sublimate on impact, expand, and help lift contaminants from the surface.
What Are The Benefits Of Dry Ice Blasting?
Dry ice blasting can clean equipment in place with little or no disassembly. It is a dry cleaning method that uses no water or chemicals, helps reduce downtime, produces no secondary waste, improves cleaning quality, reduces equipment wear, and provides an environmentally sustainable cleaning method.
What Do I Need To Start Dry Ice Blasting?
In addition to the dry ice blaster, the system needs blasting hose, air hose, nozzles, tips, a compressed air source, a power supply, and a dry ice supply. If using a portable diesel compressor as the air source, an aftercooler may be useful because it removes most of the moisture from the system and cools the air closer to ambient temperature depending on humidity level.
Where Can I Buy Dry Ice?
Most users purchase dry ice pellets or blocks from industrial gas suppliers, welding supply companies, and regional or local suppliers. Dry ice can be purchased as needed, or regular deliveries can be arranged. For manufacturers that regularly require large quantities of dry ice or operate in remote areas, a dry ice production machine may be worth considering.
How Much Does Dry Ice Cost?
Dry ice is a commodity, and prices vary by region. Check with local industrial gas suppliers or welding supply companies for current pricing and delivery options.
Are There Safety Precautions For Dry Ice Blasting?
Use proper ventilation and appropriate personal protective equipment when handling solid dry ice and operating a dry ice blaster. Wear earplugs, safety glasses, gloves, and closed-toe safety shoes. Avoid direct skin contact with dry ice because extremely low temperatures can cause cold burns.
Can Dry Ice Blasting Remove Paint?
Dry ice blasting can remove failing or weakly bonded paint, but its mild-to-medium strength may not always be enough. Paint adhesion, paint type, and primer affect the result. In some cases, even high-pressure blasting can be slow or ineffective.
Will Dry Ice Blasting Remove Rust?
Dry ice blasting can remove loosely adhered rust, surface rust, oxidation, and salt, but it will not remove deeply adhered rust or pitting oxidation. Because dry ice is non-abrasive, it is not suitable for creating contoured or white metal finishes. Deep rust still requires physical grinding or other methods.
Will Dry Ice Blasting Kill Mold?
When following IAQA standards, dry ice blasting can remove 99.9% of mold spores faster than traditional cleaning methods. It produces no secondary waste, reduces mold remediation time, uses no chemicals, and can deodorize the affected area.
Which Model Should I Choose: HTS705, HTS708, Or HTS709?
Choose HTS705 if you need a basic portable model with 5kg dry ice capacity and a flat nozzle included by default. Choose HTS708 if you need a standard professional model with 7.5kg dry ice capacity for regular workshop use. Choose HTS709 if you need the upgraded flagship model with dual pressure gauges for more precise control and more complex cleaning work.
Can I Customize A Longer Hose?
Yes. The standard blasting hose is 3m. A longer hose can be customized up to 5m, with extra fees. Contact AUTOOL Store before ordering for customization details.
