29- Do Dry Ice Pellets Rebound?

When they hit a surface, dry ice pellets change from solid to vapor form. Therefore, in general,
they do not rebound. As a rule, removed material is carried away by the compressed-air jet. Safety
goggles should however always be worn when dry ice blasting.

30- Does Dry Ice Blasting Cause Condensation?

Condensation will normally not occur when cleaning warm surfaces, as the temperature of the surface will
remain above the dew point. To prevent condensation occurring in connection with intensive cleaning or
when cleaning is performed in cold locations, the use of heat lamps, fan heaters or heated compressed air
is recommended.

31- Are Dry Ice Pellets Better than Dry Ice Blocks?

Yes. Dry ice pellets are more compact than flakes cut or grated from a dry ice block. Dry ice pellets therefore clean
more effectively. Many of the cleaning jobs currently performed with dry ice pellets would not be possible with a
dry ice blasting machine that uses flakes.

32- Are Pellets more Effective than Granulate?

Pellets consist of dry ice that has been formed into small particles under high pressure.
Their compactness makes them much more effective than "granulate", which consists of porous flakes
that have been cut or grated from a block of dry ice.

33- What cannot be achieved by Dry Ice Blasting?

Dry ice blasting is non-abrasive and treats surfaces very gently. Therefore, it cannot be used to obtain
a rough surface.

34- Can Dry Ice Blasting be used in the Food Industry?

Yes. Dry ice blasting is ideal for the food industry, as the cleaning process does not involve the
use of water or chemicals. The various applications of dry ice blasting in the food industry clearly
illustrate just how versatile the system is. The process is used to remove baked-on food deposits from
ovens and to clean mixers and moulds. It can remove paper and adhesives from packaging machinery. Dry
ice blasting can be used on plastic and metal surfaces irrespective of whether the object to be cleaned is hot or cold.

35- Can Dry Ice Blasting be used on Electronics?

Yes. Dry ice blasting can be used to clean dirt and soot from electronics without making them wet or using chemicals.
Dry ice blasting can be used on units of up to 29 kW without disconnecting the power supply. Unexpected power
failure and resulting production shutdown can be avoided by periodically cleaning electronic components.
