AUTOOL HTS708 Dry Ice Blasting Cleaning Machine

• 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 which 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 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 need it, the longgest 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 duty, so it does not support return. Please be sure to contact us if there is any problem with the HTS705 or if you have any question. 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 🙂

• Dry ice cleaning offers several key advantages over traditional cleaning methods like chemical solvents, hydrogen-oxygen machines, and walnut blasters. First, it does not require engine disassembly. Second, compared to hydrogen-oxygen machine cleaning, dry ice cleaning is a physical carbon removal process that does not damage sensitive vehicle components such as the catalytic converter. Third, unlike walnut blaster cleaning, dry ice avoids part wear. During the process, carbon deposits rapidly convert to powder when high-pressure air and -78.5°C dry ice particles collide and explode. The treated parts then undergo sublimation and decomposition, expelling impurities through compressed air. This entire process is non-toxic, harmless, and free from secondary pollution.

• The Dry Ice Blasting Machine uses compressed air as its power source to accelerate dry ice particles to supersonic speeds, which are then blasted onto the surface of the object to be cleaned. Unlike cleaning methods that rely purely on the kinetic energy of the dry ice particles, the dry ice blasting equipment also utilizes the extremely low temperature of dry ice to enhance its cleaning effect. When the dry ice particles collide with the surface, they sublimate rapidly upon impact. This process generates a swift heat exchange, causing the solid carbon dioxide in the dry ice to sublimate into gas, expanding nearly 800 times in volume. This rapid expansion creates a “micro-explosion” effect, which effectively removes surface contaminants, resulting in a thorough cleaning.

Dry ice blasting or dry ice cleaning is an environmentally sustainable cleaning and surface preparation technique.

It is similar to sandblasting, grit blasting and soda blasting in that it uses a medium accelerated in a pressurized air stream to prepare and clean surfaces. The difference is that dry ice cleaning uses recycled solid carbon dioxide (CO 2 ) pellets or particles that are blasted at supersonic speeds and sublimate on impact to remove dirt and contaminants from the substrate beneath.

The process is non-abrasive, non-conductive, non-flammable and non-toxic. It is also chemical-free, water-free and does not create a secondary waste stream. When dry ice hits the surface being cleaned, it sublimates or changes from a solid CO 2 phase to a gaseous CO 2.

There are three main factors that affect the dry ice cleaning process. These factors are the kinetic energy of the particles, the thermal shock effect and the thermodynamic effect. To explain the process more easily, we have created the following acronym (ICE).

Impact – The impact of the particles creates a kinetic effect. Compressed air accelerates the soft dry ice at supersonic speed through specially designed nozzles.

Cold – The low temperature of the dry ice pellets creates a thermal effect. The temperature of the dry ice (-109°F / -78.9°C) causes the contaminant to become brittle. This helps to break the bond between the substrate and the contaminant.

Expansion – The expansion of dry ice pellets. Dry ice pellets sublimate on impact, expanding in volume and removing contaminants.

Because of its unique properties, dry ice has many advantages that make it a more attractive cleaning solution than alternatives. Benefits include.

1. Cleaning equipment in place with little or no disassembly
2. Dry cleaning without the use of water or chemicals
3. Reduced downtime associated with cleaning
4. Cleaning without secondary waste
5. Improved product quality and reduced scrap
6. Eliminate equipment wear and tear
7. An environmentally sustainable cleaning method

Dry ice blasting requires a simple setup. Along with your dry ice blasting machine, the system will be equipped with the blasting and air hoses, applicators and nozzles that are best suited for your application.

The only other items required for the operating system are:

• Compressed air source (plant air or air compressor)
• Power supply
• Dry ice supply

If you are using a portable diesel compressor as your air source, an aftercooler may be useful. The aftercooler removes most of the moisture from the system and cools the air to within 15°F (-9.4°C) of the ambient air. This depends largely on the humidity level.

Most of our customers purchase dry ice pellets or blocks from industrial gas suppliers, welding supply companies and other regional or local suppliers. Dry ice can be purchased on an as-needed basis, or regular deliveries can be arranged to your facility. Regular delivery trucks covering a 100-mile radius are available in most major metropolitan areas. Dry ice can also be shipped using common carriers and delivered in insulated containers.

For manufacturers who regularly require large quantities of dry ice or work in remote areas, we recommend considering a dry ice production machine to meet the high demand.

Dry ice is a commodity, and prices vary by region.

When working with CO 2, precautions must always be taken to ensure that the area is adequately ventilated and that the proper PPE is used when handling CO 2 in liquid or solid form (dry ice).

Wear appropriate protective devices such as earplugs, glasses, gloves and open-toed shoes when operating a dry ice blaster

While dry ice blasting is effective in removing failing paint and weakly bonded paint, dry ice is a mild-medium, and in some applications, the use of dry ice alone is not always successful. There are many variables that determine the success of dry ice blasting, such as the adhesion of the paint and the type of paint and primer. Depending on the application, even high-pressure dry ice blasting can be too slow, too mild or ineffective.

Dry ice blasting alone will remove any loosely adhered rust, surface rust, oxidation and salt (SP 6), but it will not remove deeply adhered or pitting oxidation. Due to the non-abrasive nature of dry ice, it is not sufficient to create contoured or white metal finishes.

When following IAQA standards, dry ice blasting removes 99.9% of mold spores faster than traditional cleaning methods. The process eliminates timely manual cleaning without secondary waste, resulting in reduced mold remediation time, lower total labor costs and project time. The dry ice blasting process uses no chemicals and is able to deodorize the affected area.

Dry ice blasting leaves no residue or waste. Dry ice sublimates on impact with the surface being cleaned, creating no secondary waste, residue or moisture. This eliminates additional cleanup, disposal of secondary waste streams and additional cleaning preparation, such as masking delicate sensors or wrapping electronic components prior to cleaning. This significantly reduces the duration of cleaning projects and the resulting downtime.

Eliminating secondary waste also allows the equipment to be cleaned both in-line and while still in operation.
