Cleaning principles

The major characteristics of precision cleaning: Micro blasting impact

General cleaning principles

- Dry ice pellets are sprayed by high-pressure (low-pressure) air at a high velocity (at an average fluid velocity of Mach1.5) from the dry ice cleaner and then collide with the surface of the target object.

- These pellets then cause a number of cracks on the foreign substance layer because this layer is subjected to thermal shocks and becomes contracted due to the resultant temperature difference.

- The pellets start to penetrate through these cracks all around the foreign substances while, at the same time, subliming and expanding over 800 times in volume, thereby lifting up the foreign substances only.

- These thermally shocked foreign substances are then easily separated from the surface with the help of the wind pressure of the cleaner.

Characteristics of the ESG products

- A hydrodynamic design that ensures the flow paths and kinetics suitable for high-speed spraying

- A nozzle design that allows for the spraying operations where the target can be frozen as quickly as possible

- The effect of various sizes of pellet particles, maximizing their ability to expand instantaneously

- The optimal design of the spraying amount considering the effect of backpressure

The maximization of dry cleaning efficiency

  • Based on these cleaning principles, ESG combines hydrodynamic approaches with its empirical knowledge about design vectors while varying the cleaning conditions so that the cleaning power can be further enhanced against various foreign substances.
    (from precision cleaning to powerful cleaning)

  • The optimal design of a compressor, cleaner, and the size of the particles sprayed from the nozzles is one of the most important factors that determine the quality of cleaning. ESG boasts unparalleled technology in its cleaning operations.

  • Cleaning and washing conditions are adjusted according to the given environment (pressure, temperature, flow rate, the adhesive strength of foreign substances, the degree of age hardening, and thickness) and then prioritized accordingly (spraying amount, particle size, spraying pressure, and nozzle selection) so that optimal cleaning can be conducted.

Characteristics and advantages of the equipment

  • 01 Smart
    airflow

    It is optimally designed to facilitate airflow so that pressure losses can be prevented, and unparalleled cleaning power can be provided.

  • 02 Icing prevention
    screen

    A screen with special patterns is used to prevent the occurrence of icing and reliably feed dry ice pellets of a uniform size to the cleaner.

  • 03 Cleaner with high resistance
    to rust and impact

    Its main body and accessories are made of stainless steel and thus are highly stable and resistant to rust and an external impact.

  • 04 Internal
    storage space

    The cleaner contains an internal storage space where hand tools, nozzles, and other necessary tools can be handily kept.

  • 05 Vent unit

    This unit allows dry ice pellets and pollutants that remain inside the equipment to be discharged to ensure a more reliable equipment operation.

  • 06 Built-in
    smart vibrator

    This vibrator allows for on and off time settings and strength control so that the pellet entanglement can be more effectively prevented.

  • 07 Various models
    of dry
    ice cleaners

    Among the various models, the most suitable one can be selected and applied according to the type of cleaning so that more professional cleaning services can be ensured.

  • 08 Wheels
    that allow for
    easy movement
    and fixing

    On and off-type wheels are applied to promote the mobility and stability of cleaning equipment.

  • 09 Efficient power consumption

    The unnecessary consumption of power is minimized, and as a result, the power consumption of each type of equipment is comparable to that of a 200V fan

  • 10 Smart gun

    A switch-type lightweight gun with smart lighting functions is applied.
