Discover the 7 selection criteria for choosing the right dry ice blasting equipment for your needs… Part 1 of 2

 

Are you making the mistake of believing that buying a very expensive ice gun will allow you to cover all dry ice blasting applications?

Did you know that for 50% of the price of a very expensive dry ice cleaner, you can today:

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

The choice of your dry ice cleaner should match your needs.

So there’s no need to invest:

  • in a “small cryogenic blaster” if you want to be able to perform all types of cleaning,
  • in a “big cryogenic blaster” if you want to do small technical work on small areas…

Here is the list of the 7 criteria that your dry ice cleaner must meet to meet your needs…

1-Mono-tube or bi-tube technology…

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

A – Bi-tube technology…

Twin-tube technology uses the suction or venturi principle to project dry ice at speed subsonic: Although this system is inexpensive to buy because of the simplicity of its operation, this system is quite greedy in compressed air, and does not cover all dry ice blasting applications…

Operations on stubborn pollution are very slow, if not impossible, with twin-tube technology…

B – Single-tube technology

The single-tube technology mixes dry ice with a stream of compressed air and projects the solid CO₂ at supersonic speed: this system covers all dry ice blasting applications: “soft” to “very hard”.

This “single-tube” technology is more expensive to buy because of its operating mechanism: honeycomb plate, rotor coupled to an airlock system, but allows you to find your way around over time: reduced working time, multiplication of cleaning possibilities due to power (5X higher than the twin-tube technology).

C – Kinetic energy

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

Ec=1/2mv2

The greater the projection speed (v) (supersonic>, subsonic), the greater the kinetic energy, and therefore the efficiency of dry ice cleaning

.

Conclusion :

As a service provider, small or large dry ice cleaner, your equipment must be a single-tube equipment to be able to offer you the maximum aggressiveness.

For so-called “soft” applications, you will want to make sure that your dry ice cleaner is equipped with a pressure regulator as standard , so that you can reduce the impact force of the dry ice.

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

2- The consumption of dry ice…

 

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

Dry ice can, indeed, weigh very heavily on a quote and for many cryogenic pickers on the market, the dry ice item can even represent up to 50% of the total amount of the service.

Experience shows that an ice consumption of up to 42 kg/h (ATX25-E) with a standard nozzle provides optimum aggressiveness and efficiency.

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

E.g. control cabinet cleaning – 15 to 20 kg/h (ATX nano, 25, 25-e)

Conclusion :

A dry ice cleaner should be able to allow you to change the dry ice consumption, 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 efficiency… or speed of execution

The vast majority of applications are carried out between 3 and 7 bar of compressed air pressure: about 85% of the total performance.

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

– the working pressure,
– Dry ice consumption,
– the volume of air used

In the context of a dry ice cleaner, its working power and performance can be compared to a high-pressure cleaner:

Pressure: corresponds to the “cutting” force of the pressurized water or, in the case of a dry ice cleaner, to the “detachment” force generated by the impact of dry ice on pollution.

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

Example…

Defoaming with a pressure washer at 130 bar 17 liters/min is much faster than treatment with a cleaner at 130 bar 8 liters/min only…

The greater the amount of water, the easier it is to accompany the dirt, and the greater the yield.

The same will be true with a dry ice cleaner, with the same pressure, but with three times the volume of air and dry ice consumption.

Conclusion:

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

  • from “soft” operations to
  • recurrent and preventive cleanings to,
  • so-called “curative” services

In this article, you have discovered 3 of the 7 criteria to observe when choosing the right dry ice blasting equipment for your needs.
