New generation dry ice cleaning

DCA Deckert Anlagenbau GmbH is a medium scale company with 25 years of tradition in the field of special machine and system engineering.During the advanced development of our new device generation of dry ice blasters, our core focus was on operation friendli-ness, efficiency and economy.For your most varied requirements, we offer 4 device types that have been designed primarily as dual-hose systems for highest loads in continuous operation.

Your advantages at a glance- Effective cleaning in every smallest angle- Environment-friendly since there are no residues- Time-saving and gentle to surfaces

Dry ice cleaning process

In the case of dry ice blasting, dry ice pellets at a temperature of –78 °C are “fired” at high speed on the surfaces to be cleaned. Pellets hitting the surface cool it down extremely quickly and to a great extent. The material sticking on the surface becomes brittle. Since the carrier material and the layer to be loosened are made of different materi-als, both have different thermal expansion coefficients. Therefore, they react differently to severe cooling. Mechanical tensions build on bounda-ry layers. These tensions are also known as thermal tensions and lead to the contaminations loosening from the carrier material. (Image 1)At the time of the impact, these are immediately transformed into gaseous state owing to the kinetic energy of dry ice pellets. This leads to a quick and extreme increase in the volume of CO2. Pellets blast off depo-sits in “mini explosions”. (Image 2)

Dry ice evaporates directly without melting, i.e. without going to the liquid state. Carbon dioxide is one of the few gases that can assume a solid state. The cooling capacity of dry ice is approximately 640 kJ/kg when heating from –78.5 °C (194.65 K) to 0 °C (273.15 K); this is nearly 3 times the cooling capacity of conventional ice. However, the more impor-tant advantage is that there are “no” residues after evaporation, which is not the case with the normal ice made from water. When heat is supplied, dry ice is immediately transformed into the gaseous state.

Conventional blasting methodBlasting agents damage the surface. The resultant waste mixes with the residues of contamination and must be disposed of.(Image 3)

LT 380 Champion BlasterLT 380 is a dry ice blaster made of high-quality components and is the perfect solution for a variety of difficult industrial cleaning and maintenance activities.LT 380 is filled with nuggets (10 – 16 mm) and is suitable for extremely hard high-pressure applications.This device is portable, is fully pneumatically controlled and easy to operate.Unlike LT 380, dry ice blasters can process only pellets. Since the 16 mm nuggets have double the length of 3 mm pellets, the ordering, storage and delivery of dry ice is more profitable in the case of LT 380.

Control the ice rate setting as per your requirements: Jet pressure 6.5 bar / ice rate 1 / consumption = 30 kg/h Jet pressure 10 bar / ice rate 1.5 / consumption = 40 kg/h Jet pressure 10 bar / ice rate 2.5/ consumption = 60 kg/h

LT 380 Champion Blaster can withstand continuous operation up to a maximum jet pressure of 15 bar and an ice rate of 4.

LT 280 Double Impact – The all-rounder

Owing to the controllable pellet/particle feed and the controllable jet pressure and the use of a special grinder, LT 280 can be used exceptionally well in all areas.Thanks to its integrated 2-grinder system, the device can do fine and crude cleaning work. Push the flap to the left or the right, depending on which grinder you have chosen. The knurled grinder is suitable for fine applications, such as applications associated with headliners for automobiles, automobile seats and lime sandstone. It can also be used in conjunction with abrasive shots. It is very economical in terms of consumption. The grinder that has been furnished with troughs is suitable for rough applications, such as applications associated with underseals, the cleansing of moulds etc.

Control the ice rate setting as per your requirements: Jet pressure 6.5 bar / ice rate 1 / consumption = 45 kg/h Jet pressure 10 bar / ice rate 1.5 / consumption = 65 kg/hJet pressure 10 bar / ice rate 2.5/ consumption = 95 kg/h

LT 280 Double Impact can easily withstand operation up to a maximum jet pressure of 15 bar and an ice rate of 4.For tough applications such as moulds, ingot moulds, underseal, etc., we recom-mend the setting (of ice rate 2.5) and for light applications such as interior cleaning, motor washing, switch cabinets, fire protection, etc. we recommend a setting (of ice rate 1).

Dry ice blasting machines manufactured by DCA Deckert feature the ability to clean goods in an effective and economical manner. At the request of several users and customers, DCA Deckert developed an abrasive set for the LT 50, LT 280 and LT 380 devices.This abrasive set makes it possible to use an additive like quartz sand to improve, in a targeted manner, the cleansing-related performance that the device in question generates with the help of dry ice pellets.

Combining the LT 50, LT 280 and LT 38o dry ice blasting machines with the abrasi-ve set offers you the option of using the following operating conditions:

- Shot blasting with dry ice- Combined shot blasting with dry ice and an additive

The abrasive set can be fitted onto the DCA Deckert dry ice blasting machine in a user-friendly manner that only requires a few movements.This expands the application area to cover, among other things, activities associ-ated with the processing of metallic and mineral surfaces such as

- Derusting- Paint stripping- Cleansing of open-pored surfaces- Material removal- Roughening of surfaces before the application of paint layers/coatings etc.
