Dry ice cleaning

White Lion Trockenstrahlverfahren

Dry ice blasting procedure

The function principle

The White Lion dry ice blasting machines accelerate dry ice pellets to about 1000 km/h (ca. speed of sound) and blast them onto the workpiece that has to be cleaned. The following physical factors are essential for the effect of the procedure.

Automated dry ice blasting

Absolutely in line with the trend

Continuously clean surfaces play an important role in any manufacturing industry, especially the automotive industry. Simply being clean is not nearly clean enough. Nowadays, the demands made on surface quality before finishing are many and diverse: the surface must be fat-free, without fingerprints and with no micro-particles before it can be coated.

Versatile and forward-looking

The standards of quality expected by many manufacturers are growing continuously alongside their innovative developments. Today, dry ice blasting systems and techniques are finding versatile applications in sectors as diverse as microtechnology and medical devices.

The requirements for surfaces are therefore very high: they must be clean, dry and deburred so that further processing, finishing or coating of workpieces can be carried out smoothly in just-in-time production.

Cleanness without secondary effects with dry ice cleaning

Contrary to other blasting processes, dry ice cleaning is a process that produces only minimal secondary effects. After a dry ice cleaning, only the removed dirt remains, which can be easily vacuumed, swept up or washed away. Dry ice cleaning does not produce any damage to the surface of the material to be cleaned, and there is not a mass of used blasting material. The used blasting material sublimes into natural gases, such as those that are also present in the breathing air. The result of dry ice cleaning is a visibly cleaned surface, even with persistent soiling.

Dry ice cleaning – high-tech in blasting technology

Dry ice cleaning is a process that offers many advantages. Of all types of cleaning, it is the gentlest and most versatile process, which also guarantees the best results and prevents consequential damage. Dry ice cleaning is done without harsh chemicals, without the use of water, at the lowest temperatures and without finely distributing blasting material.
Dry ice cleaning shoots pellets of frozen carbon dioxide at high pressure. The approximately 3 millimeter long pellets have a temperature of -80 ° C. When they come into contact with the dirty surface, they blow off the dirt. Then dry ice cleaning really shows what it can do: Immediately after contact with the warmer surface, the pellet evaporates explosively. The resulting pressure also acts like a shock wave on the soiling. Because of the extremely low temperature the adherence become brittle. This makes dry ice cleaning a process that can be used in areas where others have to give up.

We start where others have to give up

What do you think happens when you treat dirty power cables with a sandblaster or computer boards with a high-pressure cleaner? What remains if plastic bodies are stripped with harsh solvents? Or when sensitive devices are cleaned with hot steam pressure? The result is always the same – the cleaning procedure results in the complete destruction of the object to be cleaned. However, it is quite different with dry ice cleaning: Whether body, computer components, cables, machines, tools and molds or upholstery and plastics – this cleaning gets everything as clean as a whistle again, without destroying the cleaning object.

Professionals with over 25 years of experience in dry ice cleaning

White Lion started dry ice cleaning over 25 years ago. At first as a service provider, we were so enthusiastic about the technology that we soon started to develop our own machines. We know what is important for efficient cleaning with dry ice and are happy to share our great experience with you. In addition to powerful and innovative products, intelligent accessories and an extensive service, we have not forgotten our roots: The service of dry ice cleaning is still in our portfolio today. Before you buy a dry ice machine, let yourself be impressed by our ability in design, manufacture and application. Call us, we will find the right approach for your challenge.

Dry ice cleaning for upholstery and textiles

Because of the non-abrasive effect, dry ice cleaning is an ideal cleaning process for upholstery and textiles. Regardless of whether it is a dirty car seat, stained armchair, dirty office chair, truck seats or dirty curtains – cleaning with dry ice makes textiles and upholstery look like new again. The procedure is the same as for cleaning solid surfaces: The -80 ° C cold CO2 particles cause the pollution to become freeze through the cold and become brittle. Through explosive evaporation, the CO2 pellets tear off the dirt. They fall to the ground and can be easily vacuumed or swept away. The special advantage of dry ice cleaning is its universal solution. No matter how complex a surface is and how many different materials it is equipped with, dry ice cleaning makes everything equally clean. Nothing has to be dismantled or disassembled for this cleaning method. The product will be cleaned as it is – and then seems like new. Of course, rough pre-cleaning is always a good idea, even with dry ice blasting. In the case of upholstery and textiles, vacuuming is completely sufficient to remove the loosest dirt particles. The dry ice blasting machine will clean the rest and removes even engrained dirt out without leaving any residue. This process is therefore also ideal for special cases of hardship: chewing gum stuck in upholstery is very difficult to remove using conventional methods without damaging the upholstery. Even chewing gum that has dried for years has no chance against dry ice blasting.

FAQ – Typical questions:

What do you need for dry ice cleaning?

A dry ice system consists of the dry ice hopper, hose and nozzle and a powerful compressor. You can dry ice pellets and keep them in a cool box. With frequent, professional use, a dry ice pelletizing machine is the better choice because it can supply any amount of pellets.



Which compressor is recommended for a dry ice blasting system?

The compressor for a dry ice blasting system should supply at least 6 bar / 6m3 pressure. Since dry ice cleaning can sometimes take a long time, a compressor with a correspondingly long service life is required. In addition, we recommend the use of a “whisper compressor” with current exhaust emission standards. Working with noise-reduced compressors is much more pleasant.



What work protection and safety is required for dry ice cleaning?

Working with the dry ice cleaner is generally not dangerous. However, to rule out freeze burns or eye injuries, we recommend long-sleeved work clothing, eye protection and gloves. Hearing protection also significantly reduces noise exposure while working.
