Cryogenic cleaning , also called dry ice cleaning , is an extremely effective, dry, non-abrasive and environmentally friendly cleaning process that can be used in various industrial areas to remove paint, dirt, grease or similar layers from the surface of materials . For some years the industry has relied on dry ice pellets for fast and incredibly effective dry ice cleaning .
From the cryogenic sandblaster tank, the pellets end up in a dosing device and then be accelerated by the compressed air emitted by a high-capacity compressor. The vacuum created in the jet gun gently sucks the pellets to accelerate them up to 300 m / s. Thanks to the high-pressure nozzles, the jet of dry ice is shot with compressed air on the surface to be treated, bringing it to a temperature of -79 ° C. Thanks to this immediate thermal effect, the layer of dirt on the surface shatters and is then removed by the next jet of dry ice.
The main advantage of dry ice cleaning is that dry ice pellets evaporate immediately after removing the dirt from the surface. This feature makes cryogenic sandblasting a cleaning system that fully respects the surface to be treated .

Cryogenic cleaning offers the possibility to clean the most stubborn dirt with extreme ease and speed, without damaging the treated surface and without wetting it, thus becoming an extremely versatile cleaning system, capable of covering many varieties of sectors of use. Below are the main areas where dry cleaning is commonly used, and related views before and after cryogenic treatments.
Car manufacturers have made dry ice cleaning a fixed part of the manufacturing process.
Containers, belt systems, dosing systems or mixers can be easily cleaned from bitumen, adhesive resins and other substances.
Cryogenic blasting is particularly suitable for buildings damaged during a fire which, if not completely destroyed, can still be restored. For this reason, cleaning with dry ice is increasingly imposed by insurance companies.
From a hygienic point of view, keeping the filters intact is not enough. The dirt deposited in the pipes is a real breeding ground for pathogens and parasites which then spread into the air.
Effective removal of release agents and residues without heating or using chemicals. Cleaning of extruders of synthetic material, parts and molds.
Cryogenic cleaning of facades with dry ice makes sense if you have to clean a building very quickly without installing scaffolding and without using water.
In foundries, molds must be cleaned at regular intervals. Thanks to cryogenic sandblasting it is no longer necessary to disassemble, cool and heat the molds. This considerably reduces downtime and costs for mold preparation and waste disposal.
Dry ice jet cleaning is used in the automotive sector for cleaning engines, gearboxes, rims, car interiors, etc.
The fields of application in this case mainly refer to small pipes, such as the production lines of the DN 12 and DN 200 sector. Thanks to cryogenic cleaning, the economic advantages are truly remarkable.
With cryogenic cleaning in just 10 minutes, vulcanization residues (rubber) are removed from the mold without damaging it. 500% time savings.
Thanks to cryogenic sandblasting, partially painted steel and copper pipes can be cleaned from cellulose and grease in about 3 minutes without damaging the treated surfaces. 500% time savings.
With cryogenic cleaning, adhesives, paper dust and grease are removed from aluminum surfaces and pneumatic pipes in just 3 minutes without damaging them. 300% time savings.
With cryogenic blasting, printing inks and greases are removed from printing rollers and other components in approximately 30 minutes without damaging them. 500% time savings.
With cryogenic cleaning, resins and adhesives are removed from the valves in about 1 minute without damaging them. 500% time savings.
With cryogenic cleaning, smoke, welding spots and combustion residues are removed from painted and non-painted surfaces of robots in about 5 minutes without damaging them. 1000% time savings.
With cryogenic sandblasting, two-component paints are removed from the steel frames in about 5 minutes. 300% time savings.
With cryogenic sandblasting, plastic, screen colors and grease are removed from the printing rollers in about 10 minutes without damaging them. 500% time savings.
With the cryogenic cleaning in about 10-15 minutes the calamine is removed from the copper, rubber and aluminum surfaces without damage. 500% time savings.
With cryogenic cleaning in about 2 minutes per square meter, acrylic graffiti paints are removed from aluminum surfaces without damaging it.
With cryogenic cleaning, oils and greases are removed from engines in about 15 minutes, without damaging the treated parts.
With cryogenic cleaning, in about 15 minutes, dust, dirt, soot and oil particles are removed from electrical conductors, relays and synthetic materials without damaging the treated surfaces.
In just about 1 minute per square meter, cryogenic cleaning removes moss, scales and environmental damage from concrete.
In about 30 seconds the bitumen present in the painted sheet metal signs is eliminated. 500% time savings.
Oil, grease and environmental dirt are completely eliminated in about 3 minutes, making the engine practically new.
In about 2 minutes the combustion residues are swept away from the stainless steel.
