Will cryogenic cleaning replace other methods?

A well-maintained space constitutes a factor of well-being for users. Likewise, when work equipment is well maintained, it increases the motivation and productivity of a company’s employees. For this maintenance, more and more companies are turning to cryogenic cleaning. Will this cleaning method replace the others?

Cryogenic cleaning and other methods

One of the most used techniques for cleaning a space in a business is stripping. This is a method of cleaning metal surfaces with the aim of ridding said surfaces of the dirt they contain. Stripping can be done in different ways. You will learn more about these ways and their value in relation to cryogenics.

Cryogenic cleaning in brief

Cryogenic cleaning is a process which consists of the use ofa mixture of dry ice and compressed air to clean a surface. The mixture thus obtained is then projected using cryogenic cleaning equipment onto the surface to be cleaned. To learn more about this material, discover cryogenic cleaning machines for various sectors such as plastics, aeronautics, electricity, agri-food, etc.

Cryogenic cleaning is a technique which, for its implementation, uses three elements. These are the cryogenic cleaner otherwise called cryogenic machine, the air treatment and the air compressor. The combination of these three elements allows the elimination, decontamination and deep and safe cleaning of different surfaces.

More clearly, cryogenic cleaning is more than cleaning dirt. This is a great way to completely disinfect a surface. At the same time, it is a means of cleaning up a living environment by destroying microbes or bacteria produced by human actions or from the living environment.


Other stripping methods

Cryogenic cleaning differs from other stripping methods such as airblasting, hydroblasting and sandblasting. Airblasting consists of the use of a stripper based on compressed air and natural abrasive diffused from an airblaster. It is important to specify that an abrasive is a substance of hard mineral origin which can tear particles off an object or surface.

Hydroscrubbing is a stripping method that requires a mixture of abrasive and water sprayed onto the surface to be cleaned. Air is added to the abrasive substance and water. The combination of the three elements allows gentle cleaning of the surface impregnated with waste. Hydrogommage is done with the machine called hydrogommage.

As for sandblasting, it is a stripping method formerly carried out using sand projected using air on a surface to remove its impurities. This method is very effective in removing impurities, but it can create lesions on the cleaned surfaces.

In addition, it is a method that presents health risks. Indeed, sand contains silica which, once in the lungs, can create silicosis, an incurable disease to which sandblasters are victims. It has been replaced by other abrasives. From now on, these are vitrified slag, corundum and other abrasives that are used. Sandblasting is done with a sandblaster.

How cryogenic cleaning works

To carry out cryogenic cleaning, also called dry ice stripping, you must have specific work tools. These must be designed to promote spraying of the cryogenic solution. They are supplemented by accessories intended to protect users from possible risks.

The main operating tools

To carry out cryogenic cleaning, you must have dry ice. It is a safe cleaner for your surfaces. You will distinguish different formats of dry ice, including dry ice pellets. They come in the form of 3 mm diameter cylinders to be stored in an easily transportable dry ice box.

Furthermore, one of the main elements used for cryogenic cleaning is the cryogenic cleaner also called cryogenic machine or dry ice blasting machine. Among the different types of cryogenic machines that exist, you will find the electro-pneumatic or 100% pneumatic cryogenic cleaner. The choice of device must be made according to your needs.

To clean your surfaces using cryogenics, you must put the dry ice in a hopper which is the ice receiving tank. It is only once this stage has been completed that you will be able to start the spraying process through a compressor. The ice will then be diffused over the surface to be cleaned and the dirt or residue cracked into small pieces. These pieces will then be eliminated by the blast of the machine.

Like all other work tools, the cryogenic cleaner needs maintenance. For this maintenance, it is recommended to contact a professional. In particular, you can go to the store in which you purchased the device which will provide you with maintenance service.

Cleaning accessory tools

The machine produces noise which can be around 85 dB(A). Due to the internal damage that this noise can cause to the user, it is recommended that they equip themselves with an acoustic protection device. You will have to wear gloves to protect yourself from dirt and avoid injury due to contact with carbon dioxide or being frozen by dry ice.

Likewise, you must equip the user of the device with protective glasses. Indeed, during the cleaning operation, it may happen that particles fly away. To protect your eyes, you must wear these protective glasses.

Cryogenic cleaning is cleaning with liquefied carbon dioxide. Carbon dioxide can cause harm when concentrated at high levels. It could deprive a body of oxygen and cause discomfort. To avoid this, you should wear a device that detects the amount of carbon dioxide present in the air.

It is important that each user is equipped with this device which then becomes individual. It sounds an alarm as soon as the carbon dioxide level becomes high enough to be considered dangerous.

Reasons for cryogenic cleaning

It is important to know why cryogenic cleaning can replace other cleaning methods. You will discover the usefulness of cryogenic cleaning compared to other cleaning methods and you will understand why it pleases its users.

The usefulness of cryogenic cleaning

This projection of the cleaning agent dry ice at -80°C has many advantages. It not only allows clean the surface to be cleaned, but also to completely restore your space. This is a cleaner that could be described as safe in terms of security and protection of the cleaned spaces.

Compared to the cryogenics technique, other methods have certain imperfections. Of course, they can remove dirt from surfaces, but their effectiveness is undermined by the possible damage they can cause. Indeed, airbrushing, sandblasting and hydrogumming leave traces of water and dust likely to cause damage to the tools.

The effectiveness of these methods can also be reduced by their targeted use. Concretely, these cleaning methods cannot be used for cleaning certain surfaces due to the nature of their cleaning solution. Indeed, the latter when cleaning can damage the surfaces. So, airbrushing, hydrogumming and sandblasting can only be effective on certain surfaces, while cryogenic cleaning has no risk of destroying the surfaces to be cleaned.

Satisfaction of cryogenic cleaning beneficiaries

The beneficiaries of cryogenic cleaning are mainly from the industrial sector. This sector produces and rejects several materials that require specific cleaning methods. This is one of the reasons for stripping. Each of the methods previously mentioned participates in these cleaning operations. Cryogenic cleaning stands out for its ability to clean all industrial surfaces. It can be used in:

  • the food, cosmetic and pharmaceutical industries to clean traces of grease and starches on tools,
  • the wood industry to clean wood processing machines, turbines or even electrical cabinets,
  • plastic and molding industry to rid rubber or silicone from molding instruments,
  • the printing industry to refurbish tools like cylinders, printing machines and equipment necessary for printing,
  • the automotive industry to eliminate all mold release and binder elements.

Other industrial sectors can benefit from cryogenic cleaning. This is the stationery sector for removing the deposit of cellulose wadding, glue, limescale and dust without having to stop the operation of the machines. In the mechanical or aerospace industry, it cleans carefully due to the electricity present.

Likewise, you can use it for the maintenance of your electrical or electronic installations. This cleaning is without risk for these installations. Note that it is equally effective in oil and gas industry equipment and tooling. It deeply cleans damage caused by mold, water, smoke or fire.

The advantages of cryogenic cleaning

Cryogenic cleaning is a cleaning technique that has the advantage of being safe and environmentally friendly. These advantages as well as several others demonstrate that it is a cleaning technique which can perfectly replace other cleaning methods.

The ecological replacement

The solution used during cryogenic cleaning has the particularity of being healthy. In other words, it was developed without adding any chemicals. Likewise, it is free of abrasives. This composition protects the cleaning environment and at the same time, the users of the machine and the workspace. They will therefore be able to move around in a healthy environment.

Compared to other methods, cryogenic cleaning constitutes a healthy, environmentally friendly solution. Dry ice is made using a method called sublimation which consists of the transformation of carbon dioxide into solid matter. This method does not harm the environment. Here are the necessary elements for a cryogenic cleaner:

  • a carbon dioxide filter,
  • isothermal conduits,
  • a carbon dioxide filter,
  • a pelletizer,
  • insulated storage bins and a storage tank.

As for other methods requiring the use of abrasives, they often involve unsafe abrasives such as polyester or ceramic which is also earth. It is important to remember that polyester comes from the synthesis of petroleum which is harmful. Sand as an abrasive is used less for its deadly silica. Regardless, these methods contain risks for the environment and the health of users.

The safe replacement

Cryogenic cleaning deeply cleans surfaces. It cleans all surfaces. Thanks to the machine’s device, it can reach very tight spaces. The peculiarity of this cleaning is the fact that it allows not only to clean, but also to restore damaged surfaces.

Likewise, cryogenic cleaning cleans without producing waste. This is also dry cleaning and therefore does not require water. At the end of the operation you will obtain a surface free of carbon dioxide residues, secondary waste and a completely dry space.

Cleaning carried out by airblasting or sandblasting has the particularity of raising and leaving traces of dust on the cleaned surface. If cleaning with hydroscrubbing is an exception to this rule, it leaves traces of water on spaces. Cleaning based on cryogenics, for its part, allows completely dry cleaning of surfaces, without dust.

Clearly, cryogenic cleaning is safe cleaning for manufacturers. It completely cleans surfaces, various objects. In addition, it restores surfaces worn by time or the impact of waste produced by industries. This is also one of the main reasons for its use, that of power against all types of impurities.

The question of whether cryogenic cleaning could replace other types of cleaning could be answered in the affirmative. You just need to look at the many benefits mentioned above to be convinced.
