Mechanical Cleaning of Heat Exchangers
Mechanical cleaning with a brush system is one of the most effective methods for cleaning (smaller) shell & tube heat exchangers. By this we mean cleaning the inside of the tubes by means of a rotating brush method. The concept is simple, a tube cleaning system powers a flexible shaft, which then rotates a brush. Due to the rotating action of the brush, there is continuous friction on the tube wall, which will cause the pollution to quickly come off. In combination with a water flush, the pollution is flushed away immediately. The water also acts as cooling for the internal core of the flexible shaft, so that the outer mantle does not heat up.
Usage within HVAC
Mechanical tube cleaning is fast, effective and very simple to perform. As a result, the method is characterized as very user-friendly and people can often carry out the work themselves. The technology is especially interesting for the following systems/installations:
- Watercooled condensers/chillers.
- Process heat-exchangers (often found within the petrochemical/process industry).
- Tubes of an Air fin cooler.
- Evaporator tubes of Aircooled Chillers.
Think of systems from well-known suppliers and manufacturers, such as: Trane, York, Carrier, McQuay etc.
Application and Usage
In principle, the tube cleaning systems can all be used from an internal tube diameter of 7,0 millimeters. Everything above is no problem. Please note that more accessories will be required for various internal diameters. This is because different diameters of brushes and shafts are available, to be able to clean any diameter of tube. In addition, it is important to choose what kind of tube cleaning machine you use, should it be powered by air or electric, etc. You can read more about this in the specific categories listed.
- Can be used from an internal tube diameter of 7,0 millimeter and up!
- Can be used for any length - just a matter of the right accessories.
- Brushes available in various materials including; nylon, brass, stainless steel etc.
- Can be used for any industry - various types of tube cleaning systems available.
The mechanical brush method allows you to remove different types of deposits. In general, the focus is more on light to medium pollution. But with the right brushes, heavier types of pollution can also be removed. Think about:
- Silt, mud and algae.
- Biofilm (slime).
