Our biggest asset is the equipment tested for thousands of hours and used for over 200 companies in Europe and throughout the world. Our planning and control systems facilitate effective, fast and dependable operation in every situation.

We cooperate with AirPower form Finland that offers a full range of high-quality products. We have chosen AirPower because their technology is proven, fast and efficient. A right selection of equipment ensures high work efficiency and reduces the risk of failures.
Main methods of mechanical cleaning

The main factor, which determines the selection of a cleaning method for ventilation systems is the type of contaminant and the material. Other important factors are the shape, construction and the level of complicity. Generally, we can single out two main methods:

• mechanical cleaning method - used for dry contaminants (dust, ash, deposits) in intake and extract ventilation and air conditioning systems (offices, utility buildings, hotels, shopping centres and similar)

- In this method, dust deposited on the inner walls of the system is removed by a spinning brush inside the duct. The brush is controlled and powered by an external device. Brushes are made of various materials such as nylon, hair, plastic, metal as it provides an optimal choice depending on the degree of pollution. Loose particles are sucked by a ventilator to the filter unit located at the end of the cleaned part. Filtration level is chosen in accordance with the building’s cleanliness class (filters ranging from EU3 to HEPA).
Dry ice blasting

Solid pellets hit against the surface and cools it, which makes the layer of contaminant brittle and fragile. The surface shrinks and makes the contaminant flake off and separate from the surface. It is then removed by blasting pellets.
Advantages of dry ice blasting

• unharmed surface
• can be used everywhere – no need to disassemble production lines
• high efficiency and precision
• universal range of application
• no extra waste except the removed contaminant
• high operating safety

Inspection:

Visual inspection of ventilation ducts is facilitated by a remote controlled robot fitted with a digital camera. The camera helps to assess deposited contaminant, detect humidity and other occurrences. With this system, it possible to collect important data such as temperature, humidity or reproduce the design of the system thanks to an in-built length meter.
Cleaning devices:

Ventilation ducts are cleaned with hydraulic or electro-pneumatic devices. Their design enables the brushes to reach for 42 meters.

Pneumatic-powered and remote controlled centring devices make it possible for the brushes to be kept in a correct position when wide ducts are cleaned.
- Alternative method of cleaning is using compressed air. The technical difference is that brush is replaced by a pressure spinning nozzle. This method is less effective, especially for much-contaminated ducts, but it can be used as a supplementary method.

- Robot equipped with a brushing head and a camera is sometimes used. Due to a low efficiency, it is used only in places where other methods can’t be used.

• chemical cleaning method - used for systems heavily contaminated with fat or other technological substances which are hard to remove (kitchen and industrial system extracts)
Chemical agents used in this method remove the contaminant at a molecular level – they decompose the fat’s inner structure making it easier to remove.

They are safe for the environment and surfaces.
Before cleaning
After cleaning
The camera provides access to the extreme parts of ducts, which are not equipped with inspection holes. All records of testing results can be used for comparative purposes and as the basis for a commissioning report.

The camera can be used to supervise the cleaning process of difficult parts such as shutter louvers.
