Schmitz Cleaning Balls

Cleaning systems by Schmitz

In collaboration with modern technology, Schmitz has manufactured and developed a state of the art cleaning system in the form of cleaning balls that are used to cleanse complex processing systems.

The cleansing ball is considered an important tool for any automatic heat exchanger or condenser cleaning system.  Much other related equipment such as the ball strainer, the ball collector, and the recirculating pump are only tools that inject the cleaning balls into the required system that passes through the condenser, extracting it along the process.


This unique cleaning system benefits by offering high-quality operational value, eliminating a need for a manual cleaning system.


About Schmitz Cleaning Balls


Guenter Schmitz has many years of experience in putting together cleaning balls for the chemical industry, power industry, and for seawater purification plants. The complete range of cleaning balls are available at CITC with warranty from Schmitz.


With Schmitz’s extensive experience with condenser tube cleaning systems, it is also advisable to optimize its force by considering the following,


– A cooling water source
– The cooling water quantity
– Tube dimension
– Tube material

A closer look at the cleaning system




In all cooling water applications, layers of fouling, such as slime, mud or silt, form on the inner surface of condenser and heat exchanger tubes even with cooling water velocities of 2m/s.
SCHMITZ normally recommends Type RS open pore structure sponge rubber cleaning balls for continuous cleaning with 8 to 12 cleaning ball passes per tube per hour.




In cooling towers or other open evaporative cooling water systems, the water becomes highly concentrated with certain chemicals. The solubility limit is exceeded and hard crystalline deposits, such as scaling, form on the tube surface.
SCHMITZ ring coated abrasive cleaning balls Type RA are first used to clean fouled tubes, typically for a period of a few weeks. Continuous cleaning with Schmitz cleaning balls without abrasive layer then hinders the growth of nuclei.




Copper alloys have marginal corrosive resistance in seawater. Although artificial protective films can be formed by using ferrous sulfate, excessive sponge ball cleaning produces lacquer like films which easily flake away on drying.
SCHMITZ recommends the use of cleaning balls without an abrasive coating Type RS for 1 hour per day immediately prior ferrous sulfate dosing. This produces compact, matt brown films, giving an optimum combination of heat transfer and corrosion resistance. Abrasive balls fully coated Type RAT is effective for removing such films.




Although titanium and high-performance stainless steels have excellent resistance to corrosion they are more susceptible to fouling than copper alloys. This can be attributed to the lack of copper ions, which are toxic and tend to hinder the formation of biological fouling.
SCHMITZ recommends continuous cleaning, Type RB scouring balls with 8 to 12 cleaning ball passes per tube per hour. Additionally, a basic charge of granulated balls Type RG should be circulated every few months to avoid a possible build-up of strongly adherent fouled layers.
