All about CO₂

Deutscher Text >>>

All about CO₂ does not only mean a complete product range: above all it means complete and individual CO₂ solutions including professional consultation and best possible after sales attention. ASCO’s service starts before and does not end with the sale.

ASCO has all you ever need to make your CO₂ project a success.

Our product portfolio is based on the expertise of over 130 years of practice in the field of CO₂ and dry ice. During this time, we have recognized that only a continuous development and improvement of products ensures our future and the success of our customers. Our ISO certification underlines our demand on our products and Services (IQNet ISO Certificate 9001:2008  and SQS Certificate ISO 9001:2008).

Since 2007 we belong to the international industrial gas enterprise Messer Group and we are the competence centre for CO₂. This merger with the German BUSE Gastek GmbH & Co. KG headquartered in Bad Hönningen, in 2014 allowed us to concentrate and substantially expand our expertise and product portfolio, especially on the complex field of CO₂ recovery.

Dry Ice Production - Info >>>

For a maximum of quality and flexibility in the daily working process and remarkable cost savings. As a provider of complete CO₂ solutions we are not only your contact in regards to dry ice production machines in various capacities but also your competent partner for setting-up your in-house dry ice production.

What is dry ice?
Dry ice is the name for solid CO₂. At atmospheric pressure it has a temperature of approx. -79° C (-110,2 °F). The evaporisation is residue free. Dry ice is non toxic, non flammable, inert, tasteless and odourless. It is white and has a density of approx. 1'500 kg/m3 (93,64 lb/ft3) in its compact form.

Applications of dry ice
Dry ice is an ideal cooling media which can be used for many applications. It has a high cooling capacity. Dry ice blocks/slices or dry ice pellets are used for cooling purposes.

ASCO Dry Ice Blasting is a powerful, gentle, dry and ecologically friendly cleaning method causing no secondary waste. It is applied in many industries. For the cleaning of surfaces with our ASCO dry ice blasting technology dry ice pellets with the diameter of 3 mm (0,12 in) are standardly used. Dry ice pellets with a diameter of 1.7 mm (0,06 in) can also be used for the cleaning of delicate surfaces. For cooling purposes dry ice blocks and pellets with a bigger diameter are used.

How dry ice is produced
Dry ice is produced from liquid carbon dioxide (CO2). Inside a dry ice pelletizer, the liquid carbon dioxide is expanded under controlled conditions to form dry ice snow. This snow is then pressed through an extruder plate into round, hard pellets (elongated grains with a diameter of 3 mm or 1.7 mm according to the used extruder plate) for dry ice blasting purposes or into larger pellets/dry ice slices/blocks for cooling purposes.  . 

Dry ice for cooling purposes
Dry ice is an ideal cooling media which can be used for many applications. It has a high cooling capacity. Dry ice blocks/slices or dry ice pellets are used for cooling purposes.

Dry Ice Blasting - Info >>>

As a provider of complete CO₂ solutions we offer a comprehensive product range in the field of dry ice blasting including complete dry ice logistics. On top of that, we are your competent partner for all interest and matters concerning dry ice production and setting-up an in-house dry ice production.

How does dry ice clean?
The ASCO Dry Ice Blasting machine accelerates with compressed air the dry ice pellets to a speed of approx. 300 m/s (984,25 ft/s). The pellets hit the object to be cleaned. The surface is shock-frozen in a fraction of a second. Due to the sudden thermo shock generated on the surface to be cleaned, the coating/dirt contracts, becomes brittle and cracks. Due to the cracking of the surface, the pellets can reach under the dirt and remove it. The additional kinetic energy removes the coating/dirt from the surface. Immediately after impact, the pellet sublimates and goes back to atmosphere as a pure gas (CO₂) without leaving any moisture behind. The only thing left is the coating/dirt removed from the surface and no blasting media has to be disposed of. Since the hardness of the pellets is only approx. 2 Mohs, the cleaning is virtually non-abrasive, and the surface quality is maintained.

The thermo shock
As a result of the sudden and intense temperature shock on the surface, the coating or impurity contracts.

The cracking
As a result of the contraction the coating cracks and the material becomes brittle due to the cold.

The cleaning
The dry ice pellets hit the surface with great speed and remove the detached coating and clean the surface material.

CO₂ Production and CO₂ Recovery Plants - Info >>>

Advanced CO₂ Production and CO₂ Recovery Plants to gain high-purity CO₂ for all industrial and food applications, individually adjusted to our customers’ requirements.

What is CO₂?
Carbon dioxide is the combination of two atoms of oxygen joined with a single atom of carbon. Its chemical formula CO₂, is almost as well-known as that of water, H2O, and it is frequently referred to by its formula rather than its name.

In nature’s chain of life, the mutual dependence of plant and animal life is maintained through the link of carbon dioxide. Every time we breathe we release this gas, which plants need for life. Through the process of photosynthesis, the plants separate the carbon from the oxygen. In turn, plants release the pure oxygen, which we need to survive. We reverse the process, and by combining the oxygen with carbon from the foods we eat, produce carbon dioxide again.

CO₂ is a colourless, inert gas approximately 1 ½ times heavier than air and 0.03 % is present in the earth’s atmosphere. It is odorless, has a sweet biting taste (soda water) and is highly stable (difficult to separate).

It is produced in varying amounts by the common process of combustion of fuels high in carbon content. The most common source of fuel for combustion is oil which, when mixed with the correct proportion of air, burns to produce around 15 % CO₂ in the flue gases of a CO2 plant. After combustion has taken place, the CO₂ can be separated from the flue gases and, through a simple process, made available for the many commercial purposes to which it can be applied.

CO₂ can exist in three forms:
- in gaseous form: for the beverage and food industries
- in liquid form: in a storage tank under pressure
- in solid form:  called dry ice (for cooling, blasting etc.)
