Our revolutionary technology

Our grinder system directly in the unit. This makes the COOLMASTER® unique.

Because in comparison to conventional dry ice blasting units, which often grind the dry ice pellets first in the gun: the grinding mill of the COOLMASTER® is placed before the actual blasting process and brings the dry ice pellets into a uniform size there.

Due to the special arrangement of the grinding mill inside the dry ice blasting unit, the requirements for the air supply are considerably lower than with other dry ice blasting units.

Another advantage of this design, the blasting gun is light and handy, a plus that should not be underestimated in daily handling and longer cleaning tasks.

The grinding mill – Right in the middle:

  1. Hopper with pellets
  2. Compressed air
  3. Rotating dosing roller
  4. Grinding rollers
  5. Blasting hose
  6. Blasting gun with laval nozzle

The advantages:

  • No blockage of the unit or grinding system due to technical reasons
  • Homogeneous and consistent cleaning jet
  • Precise dosage of compressed air and amount of dry ice
  • Grinding size of the pellets between 0,2 and 3 mm

Intuitive operation – so easy:

1. Grinder adjustment

You set the grinding degree according to your cleaning task and surface structure. The COOLMASTER® grinds dry ice particles flexibly from 0.2 – 3 mm.

You can change and adjust the size of the dry ice particles at any time.

2. Selecting the blasting nozzle

When the particle size has been set, simply screw the matching blasting nozzle onto the blasting gun.

The nozzles can be easily changed under all operating conditions.

3. Program setting

The adjustment of the compressed air is essential for an effective and precise cleaning. Therefore the compressed air jet is continuously adjustable from 0.5 to 10 bar (7 to 144 psi).

Standard values are already stored in the programs. In addition, you can set and save frequently used values individually.
