We solve well-known problems and creates long-term investments

When was the last time you performed fluid treatment in your HVAC system? How much energy does your property actually use to keep warm? Do you have high maintenance and repair costs on your HVAC system? Or are you worried that your investment in your HVAC system is not sustainable in the long term?

Instead of repairing and replacing components in advance, you can instead prevent with fluid treatment, such as applying permanent degassing. This is done by installing a permanent vacuum degasser. Measures that involve little effort but have a big impact – exactly what TTM’s fluid treatment product range is all about. Our products increase the energy efficiency of the system fluids, reduce corrosion and extend the life of the components.

Flow efficiency is not a matter of course

Efficient flows to all parts of a heating and cooling system are the key for energy efficiency, but usually requires liquid treatment in the form of degassing. Water contains gas; oxygen, nitrogen and in some cases carbon dioxide. The gas content from tap water is about 8 mg of oxygen and about 13 mg/l of nitrogen per litre. The gas content is affected by pressure and temperature; the higher the pressure and the lower the temperature, the more gas a liquid can carry. If the oxygen/gas content is high, degassing is needed.

Water containing gas at varying pressures and temperatures causes gas bubbles to precipitate, which disrupts the flow and reduces the efficiency of heat exchangers, pumps, radiators, fan coils etc.

The flow disturbances are usually experienced through difficulties in getting heat or cooling out to all parts of the HVAC system where varying pump capacities and unbalanced systems are common symptoms.

Even at a few grams of oxygen per litre, the corrosion boom starts and fluid treatment is a must. In system fluids that are not degassed, the corrosion breeze “burns” brightly, forming dirt and magnetite that “eats” the system components from within.

The purpose of fluid treatment by degassing is to reduce the gas content to a level where corrosion stops and the system fluid regains its optimum energy-carrying property.

The easy way to degas the system fluid!

  1. If the oxygen level is above 1 mg/l, the fluid needs degassing!
    A partial stream is pumped from the main pipeline and is treated at vacuum in TTM NoXygen®. The gases are released and vented off and the fluid returned to the system. After the initial boost degassing, one hour’s operation daily is enough to keep the gas content at at a low level.

  2. Filter with TTM MAG 54, 76 or 250
    Magnetite and particles are removed efficiently with TTM MAG 54 or TTM MAG 76 together with TTM NoXygen®.

  3. For heavily soiled systems TTM MAG 250 is used to remove magnetite and other particles efficiently.

  4. Pressurization unit GeniX GE18
    The unit provides a constant operating pressure in the heating system.

  5. Pressure equaliser vessel
    In systems that use pump expansion, TTM Offset is used together with TTM NoXygen® to counteract pressure variations.

    Fluid replacement
    Replace the fluid if the conductivity is higher than the tap water’s, if the fluid smells bad, is yellow/brown or has low pH and/or foams. With TTM Refill, the fluid replacement takes place during operation.
