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 friendliness, 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 materials, both have different thermal expansion coefficients. Therefore, they
react differently to severe cooling. Mechanical tensions build on boundary 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 deposits 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 important 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 method
Blasting agents damage the surface. The resultant waste mixes with
the residues of contamination and must be disposed of.

LT 380 Champion Blaster
LT 380 Champion Blaster
LT 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
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/h
Jet 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 recommend 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).

LT 50
Shop Blaster
LT 50 High Power
LT 50 Shop Blaster , LT 50 High Power
LT50 is the smallest dry ice blaster available in the market. It is
handy, easily transportable and suitable for continuous operation.
It is an optimum addition to the existing product range.
LT 50 Shop Blaster has been designed for light applications and
LT 50 High Power has been designed as a powerful package for heavy
duty applications. Both device types are equipped with a patented
electrically-operated grinder and a compact housing.
Thanks to a suitable electronic controller, the grinder can be optimally
adjusted as per the operating pressure and the cleaning task.
Owing a lower compressed air volumetric flow consumption, only
small compressor systems are required for supplying compressed air.
Thus, there is no need of cost-intensive investments.
The LT 50 series offers all advantages of cleaning using dry ice.

Abrasiv set
Dry ice and additive – LT
280 Double impact
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 abrasive 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 associated 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.

Equipping the device types with the abrasive set makes it possible to use
additives such as quartz sand, glass beads, nutshells etc. to enhance the
cleansing-related performance that the devices in question generate with
the help of dry ice pellets.
Devices belonging to the LT 50 series include Shop Blaster devices, which
are designed for light applications, and High Power devices, which are
designed for more intense applications. These are the smallest dry ice
blasting machines that are available in the market.
