What's CTW-16?

Thanks to the inhibitor being a part of the fluid, CTW-16 has no negative impact on pipe goods, radiators, water heaters, washers, etc. These characteristics together with the biodegradability makes CTW-16 unique. The liquids commonly found on the market today are often harsh chemicals that must be sent for disposal after use. CTW-16 can be drained into the sewage system without any problems - it will actually give the drains a cleansing.

CTW-16 is:

  • Unique product that is completely biodegradable.
  • Cleaning liquid for all types of water systems.
  • Acidic liquid of pH 1.5 (neutral pH is 7).
  • Consisting of citric acid, phosphoric acid and inhibitor.

What can CTW-16 do for you?

In the central heating system water is always heat conductive. This water is taken from the municipal network, for example a river, a stream or your own well. Water quality is varying depending on the source. In general, one can say that water from the municipal network, rivers, lakes, etc. is soft water with a higher pH than water from drilled wells. This water is often hard and with a lower pH and usually contains more calcium. Another problem with water from wells is that it is not clean. When water is taken into a closed system and is used as a heat conductor it's heated up and that's when problems arise. Impurities accompanying the water slowly falls out and settles as a coating on the inside of the pipes, heat exchangers, valves, etc. The coating can become very solid and act as insulation in the system so that the heat from the water is not used to the desired extent. 

This coating consists essentially of:

  • Lime.
  • Magnetite.
  • Rust.
  • Humus.
  • Bacteria.

CTW-16 is easy to use.


To compensate for the loss, the system must run at a higher temperature than otherwise necessary. This leads to a higher energy consumption and increased costs.

The solution

CTW-16 is the solution to the problem. CTW-16's unique characteristics dissolve the deposits so that they return to liquid form. This has a natural explanation. The contaminants have entered the system as water. The mixing ratio is about 1:10; that's 10 liters of CTW-16 in 100 liters of water. The ingredients are mixed in a specific ratio that causes an immediate attack on the contaminants. All impurities are gradually returning to a liquid form and can then simply be flushed out of the system. Previously acids have been used for this purpose, but these have proven to be corrosive to both tubes and gaskets. CTW-16 is more lenient, and in the long run a more cost-efficient solution.

CTW-16 removes all impurities without damaging any materials in the plant.

Rubber and fiber gaskets will not be damaged by CTW-16. Since it's biodegradable, the fluid is easily disposed. It can simply be poured in the drain. This is a great advantage compared to acids that must be drained in barrels and sent for disposal. Imagine the cost of transporting 30,000 liters of hazardous materials. One should keep in mind that older systems are sometimes held together by rust and calcium deposits. This means that a cleaning is likely to cause a leak. It's preferable that this occurs during a controlled and planned event.

Who needs CTW-16?

Anyone with heating and cooling systems. Wherever water is used as heating and cooling medium, CTW-16 is the preferable solution. Water contains minerals, limestone and other impurities, which over time dissolves and creates a coating on pipes, heat exchangers, etc. These pollutants create an insulating layer inside the facility. Over time these layers thicken and significantly reduces efficiency. To still achieve the desired effect, the consumption of water, oil or energy must be increased. In this way, both industrial plants and private homes waste energy equal to several power plants annual production every year. When it comes to energy conservation, much more can be done than switching to low energy lightbulbs and installing saving showers. Keep in mind that the CTW-16 can be used anywhere where water is used as a cooling or heating medium.
