Discover the 7 selection criteria to choose the cryogenic cleaning equipment adapted to your needs… Part 1/2

Are you making this mistake of believing that buying a very expensive cryogenic scraper will allow you to cover all applications in cryogenic cleaning?

Do you know that for 50% of the price of a very expensive cryogenic cleaner, you can today:

  • Perform all cryogenic cleaning services,
  • For a dry ice consumption up to 50% lower for the same type of work?

The choice of your cryogenic cleaner must match your needs.

No need to invest:

  • In a "Fly fairy" if you want to be able to perform all types of cleaning,
  • In a "canon" if you want to carry out small technical works on small surfaces…

Here is the list of 7 criteria that your cryogenic cleaner must fill to meet your needs…

1-mono-tube or bi-tube technology…

 

There are 2 types of equipment: bi-tube machines and single-tube machines.

A-Bi-tube technology…

Bi-tube technology uses the principle of suction or venturi to project dry ice at subsonic speed: Although this system is inexpensive to purchase because of the simplicity of its operation, this system is quite greedy in compressed air, and Does not allow to cover all the apllications of cryogenic cleaning…

Operations on persistent pollution, are very slow see impossible with bi-tube technology…

B-Mono-tube technology

Mono-tube technology, mixes dry ice in a compressed air stream, and projects solid CO2 at supersonic speed: This system covers all applications of cryogenic cleaning: soft to very hard. This technology is more expensive to purchase because of its operating mechanism: frame tray, rotor coupled to a airlock system.

C-Kinetic energy

The effectiveness of cryogenic cleaning is based on the interaction of 3 phenomena, including kinetic energy:

Ec = 1/2mv2

 

The higher the projection speed (v) is (supersonic > subsonic) and the more kinetic energy and therefore the efficcacité of cryogenic cleaning are important.

Conclusion:

As a service provider, small or large cryogenic cleaner, your equipment must be a mono-tube equipment in order to offer you the maximum aggression.

For the so-called "soft" applications, you will ensure that your cryogenic cleaner is equipped with a pressure regulator in a series, in order to reduce the impact force of the dry ice.

A fragmentation nozzle (dispsoitif of dry ice crushing will reduce the mass (m) of the dry ice for milder treatments.

2-The consumption of dry ice…

 

The consumption of dry ice is very often a neglected position in the choice of a cryogenic cleaner.

Dry ice can indeed weigh very heavily on a quotation and for many cryogenic scrapers on the market, the dry ice station can even represent up to 50% of the total amount of the benefit.

Experience shows that an ice consumption of 50 kg/h Maxi (ATX25-E, 25, 30, 30-E & 80), with a standard nozzle, provides aggressiveness and optimum performance.

A cryogenic cleaner must also be able to work with low consumption.

Ex: Cleaning Electrical Cabinet-15 to 20 kg/h (ATX Nano, 25, 25-E, 30, 30-e, 80)

Conclusion:

A cryogenic cleaner must be able to allow you to modify the consumption of dry ice, depending on the application, and a maximum dry ice consumption of 75 kg (+ 50% compared to firing at 50 kg/h) is sufficient.

3-Power and work performance… or speed of execution

The vast majority of applications are made between 3 to 7 bar of compressed air pressure: About 85% of total benefits.

To the cleaning power you must add the performance (or speed of execution), defined by:

-Working pressure,
-The consumption of dry ice,
-the volume of air used

As part of a cryogenic cleaner, it is possible to compare its working power and performance with a high pressure cleaner:

The pressure: corresponds to the "cutting" force of the water under pressure or in the case of a cryogenic cleaner with the force of "detachment" caused by the impact of the carbonic ice on the pollution.

The volume of water (high pressure cleaner) and the volume of air (cryogenic cleaner) correspond to the accompanying force of the pollution.

Example…

The defoaming with a high pressure cleaner at 130 bars 17 litres/min, is much faster than the treatment with a cleaner at 130 bars 8 litres/min only…

The greater the quantity of water and the easier the accompaniment of the dirt is, and the more important the yield.

The same will be the case with a cryogenic cleaner, with the same pressure, but a volume of air and a dry ice consumption of 3 times more important.

Conclusion:

If your goal is to be able to perform all possible and imaginable benefits:

  • From "soft" operations through
  • Recurring and preventative cleaning,
  • So-called "curative" benefits
