Dry ice cleaning with

COOLMASTER®

The latest in dry ice cleaning

Heavily soiled motors, tools or production parts? Sensitive or hard to clean surfaces? Starting

today, you can meet the widest variety of challenges with just one device:

the COOLMASTER, the latest in dry ice blasting units. Developed with the aim of permanently

changing the cleaning industry and providing a product which sets new cleaning standards in

all industries, and this also improves companies’ economic effi ciency. The COOLMASTER starts

where other cleaning methods and devices reach their limits – unbeatable for fl exibility

and range of applications. This makes it perfect for removing contaminants in all

sectors. Particles of varying sizes, surfaces and degrees of soiling are cleaned effi -

ciently and powerfully, yet gentle. At the same time it saves resources; it is less time

consuming than manual cleaning and it reaches even the most diffi cult areas, it

reduces the downtime of machines as they often do not need to be dismantled, and

fi nally machine parts no longer need to be sent off for cleaning. The COOLMASTER

sets itself apart with its ergonomic, modern design and provides the new standard

in quality and performance.

Flexible, robust and versatile

Due to its fl exibility, the COOLMASTER can be used across all industries and removes dirt of any size

from any surface. Highly robust and with a low level of noise, the COOLMASTER is especially suitable

for permanent use in the industrial environment. The device sets itself apart with its performance and

modern, ergonomic design

Precise and thorough cleaning

With the help of dry ice, the COOLMASTER is able to powerfully and effectively clean even

the most sensitive surfaces and hard to reach areas. It works gentle enough not to cause

any damage. The procedure is dry and therefore leaves no trace of water or detergent.

Remedies of dirt particles can easily be disposed of after the cleaning process.

Mobile and easy usage

With a weight of only 36 kg, the COOLMASTER is a compact and portable helper which can be used

readily with a small amount of training. The handling of the COOLMASTER is intuitive and through the

guidance of the menu is easily managed with the control knob and LCD display. A built-in interface offers

the possibility to individualize programs and settings for the option to connect automatic solutions.

Optimizes workfl ows and saves costs

It is no problem for the COOLMASTER to clean during ongoing operations. The loss of production through

machine downtime and the amount of time necessary with manual or chemical cleaning procedures

is reduced. Since is no damage to surfaces, it extends the lifespan of forms and tools, thus enabling a

reproducible product quality. In addition, eliminating the use of chemicals increases safety.

Economical operation

The COOLMASTER uses an average of only 15-18 kg dry ice per hour which can be regulated and dosed

with its innovating grinding system. For operating in the industry, already existing compressed air

systems can be used, as the device only needs an average of 600-700 l/min of compressed air. The air

pressure can be regulated which enables noise-optimized working.

Environmentally friendly cleaning – without any chemicals

Cleaning with the COOLMASTER requires absolutely no water or chemicals. In addition, after the

cleaning procedure no blasting residues are left so that there is no strain on the environment. The CO2

required for the production of dry ice is edible and is gained from natural resources in the earth or as

recycled by-product of industrial processes.

The process of dry ice cleaning

What is dry ice?

Dry ice is produced from liquid carbon dioxide (CO2, carbon acid), a noninfl am-

mable, odorless natural gas. It can be found in large quantities in volcanoes and

springs, as well as in plant or human metabolisms. A huge advantage of dry ice is

the temperature of 78.5 C. On impact with a hard surface it immediately transforms

from a solid to gaseous state and completely dissolves without any residues. This

could be considered an essential characteristic in the use in cleaning procedures.

How is dry ice produced?

In a so called pelletizer, liquid carbon dioxide is relaxed under atmospheric pres-

sure through a physical process. Thereby a part of it evaporates, thus depriving its

environment warmth. The remaining carbon dioxide gets cooled and dry ice snow is

formed. Afterwards it is pressed through a matrix of pelletizer resulting in solid and

elongated dry ice pellets.

The functioning of dry ice cleaning

When cleaning with dry ice, the particles are used as blasting medium. With the help of a dry ice blaster like the COOL-

MASTER, the particles are being accelerated to an extremely high speed with a stream of compressed air, and subse-

quently blasted on the object that needs to be cleaned. This creates three different effects which enable an optimal

cleaning procedure. With the fi rst effect, the kinetic effect, dry ice particles are accelerated to high speed. The following

impact of the particles causes the second effect: as they hit the layer of dirt with -78,5°C it is cooled down, contracts and

builds cracks. Through the different coeffi cients of thermal expansion the compound of surface and dirt is loosened. The

third, and most important effect, results through the change of the physical condition of the dry ice particles: On impact

the carbon dioxide directly transforms from solid to a gaseous state and expands about 700 times the volume within a

split second. This expansion literally „blasts off“ the dirt from the surface. At the end of the cleaning procedure the loose-

ned dirt particles can be easily disposed of.

Our revolutionary technology

Your benefi ts at a glance:

No blockage of the unit or grinding system due to technical reasons

Homogeneous and consistent cleaning stream

Precise dosage of compressed air and amount of dry ice

Grinding size of the pellets between 0,2 and 3 mm

Grinder settings:

Depending on the structure of the surface the required size of dry ice particles can be set within

seconds and adjusted to changing conditions. Whether coarse or fi ne, sensitive or robust, you can

easily choose the suitable particle size between 0,2 and 3 mm with the help of the color coded area

on the dosing lever.

Choice of blasting nozzle:

If the particle size is set, only the blasting nozzle needs to be connected with the blasting gun

according to the color-coded area and particle size. The nozzles can be easily changed under all

operating circumstances and just need to be screwed on the muzzle of the basting gun.

The grinding system is the core element of the COOLMASTER and one of the main reasons for its high cleaning power

and fl exibility. It is located directly inside of the machine and therefore works extremely precise, as compared to con-

ventional dry ice blasting machines where the dry ice is shredded as late as in the blasting gun. The grinding system of

the COOLMASTER is placed before the actual blasting process where it brings the pellets into a consistent size. After

grinding, the dry ice particles are accelerated by compressed air and then blasted evenly and well-aimed onto the com-

ponent that needs to be cleaned. Because of the specifi c arrangement of unique position of the grinding system within

the dry ice blasting machine, the requirements for the compressed air supply are signifi cantly lower than with other dry

ice blasting machines. Furthermore the blasting gun is lightweight and handy, the cleaning stream works homogeneous

and consistent.

Compressed air settings:

Next to the setting of the particle size the adjustment of compressed air is essential for an effective

and precise cleaning procedure. The homogeneous stream of compressed air allows a pressure of

0,5 to 10 bar and can be changed through the program in the menu. Default values are defi ned to

make the compressed air settings as easy as possible. However it can also be adjusted individually

and settings in the user menu.
