Dry ice granules are obtained by pressing at a pressure of 160-200 atm, due to which its density becomes very high, and the lumen of the granules is almost transparent. Regular blocks of dry ice, white in color and very fragile. granules, in turn, are loose and solid, so they are used for high-quality cleaning.

No, only small cylindrical pellets with a diameter of 1.6 or 3 mm.

The grinder in the TRANSFORMER machine can only accept loose pellets with a size of 3 to 20 mm in diameter, it does not work with blocks.

It immediately evaporates and turns into CO2 gas.

It flies off in the direction where the air jet with pellets blows. dry ice is inert and does not interact with dirt and the surface to be cleaned.

When cleaning, a screw compressor is used, which supplies a large amount of air during the cleaning process through the nozzle, so in 99.99% of cases, there are no breathing problems. if the room is closed, has a small volume or low ceilings, and the container with pellets is located in it, then there is a need to ensure constant ventilation of the room. This is explained by the fact that CO2 is heavier than air.

Dry ice is sold in some large cities of Russia by independent producers, so dry ice is a market commodity, not a monopoly. In order to find out the nearest manufacturer of dry ice, you can contact IRBISTECH, our specialists are always ready to provide this information.

Storage is carried out in special industrial thermal containers on wheels with a capacity of 100,200,300 kg of ice; there are also inexpensive household containers for 50-75 kg with good characteristics, made of foam. All these containers have basic properties: tightness and a wall thickness of 10 cm. Some local dry ice producers provide containers for rent.

5-8% of the volume per day. The rate of evaporation depends on the time of year. Before the first opening of the container, 3-millimeter pellets can be safely stored for up to three days without changing their properties. Large pellets with a diameter of 6-20 mm evaporate more slowly than pellets with a diameter of 3 mm, due to the smaller specific area per 1 kg of pellets.

In the machine, everything is thought out so that, with proper operation, it will serve for many years. In case of violation of the operating rules, the following damages may occur:

• breakage of the operator’s handle when it is hit hard;
• damage and abrasion of the batch shaft with a seal, knives and shredder sieves in case of frequent ingress of solid dust into the hopper or through the air flow, as well as in case of a single ingress of a large solid object into the structure, such as, for example, a nut or bolt.

For uninterrupted operation of the plant, the compressed air must have a low humidity (the maximum value is 5% relative humidity, the dew point is below 0°C). The compressed air must be free of oil, dirt and large particles. The compressed air must, at a minimum, comply with the air quality indicators according to «ISO 8573, class 3». 

Compressor for a point solution: removal of dirt of light complexity, which are easily removed by hand with a rag (for example: oil deposits, light deposits, crumbly and brittle dirt, industrial dust, street dirt): working pressure of 7 ATM and 3 cubic meters / min according to FAD (estimated price 330,000 rubles. with an electric drive of 18 kW);

Universal compressor for cleaning services: for removing medium-complexity dirt (including paint, deposits, grease deposits, food soot, dried glue and bitumen): working pressure 8-9 ATM and 4-5 cubic meters / min according to FAD (estimated price 600,000 rubles. with an electric drive for 30 kW);

Special applications: for removing high-complexity contaminants (including old rust,» stone » deposits on a steam turbine, polymer and fire-fighting paint): working pressure of 10-12 ATM and 7 cubic meters / min according to FAD (estimated price 900,000 rubles with an electric drive of 55 kW).
