Innovative Tank Cleaning
Using State-of-the-Art Dry Ice Technology
Effective removal of stubborn residues
High-viscosity or hardened residues in tanks often pose a major challenge during cleaning—especially when they cannot be removed using conventional flushing methods.
Our innovative dry ice process offers an effective solution:
Through targeted cooling, any remaining product residue in the tank is cooled to such a low temperature that it hardens completely. In this solid state, it can then be easily and efficiently removed mechanically—for example, using a mini excavator or conveyor systems.
To ensure complete freezing, cushions or bags filled with dry ice are placed directly on the product. A tube is integrated into the dry ice to allow for the controlled release of the CO₂ that is produced. Since the bags used are not completely gas-tight, the CO₂ can also escape through designated openings.
The CO₂ released in the tank room is continuously extracted and properly treated and rendered harmless in the combustion chambers of our partner company, ETS. The position of the extraction system is flexibly adjusted to the progress of the work and the location of the dry ice packs being used. Explosion-proof ATEX blowers can also be used to ventilate the tank.
Dry ice blasting – thorough, dry, and gentle on materials
In addition to removing products, dry ice blasting enables particularly efficient cleaning of tank interiors and internal components.
When the dry ice pellets come into contact with a surface, the CO₂ sublimates immediately—transitioning directly from a solid to a gaseous state. This loosens dirt without damaging the surface.

Logistics and Use of Dry Ice
The dry ice (cryopellets) used is delivered in special insulated containers with a typical capacity of approximately 400 kg. These containers are portable and can be easily transported to the desired location using a forklift or pallet jack.
