We solve well-known problems and create sustainable investments
How much energy does your property really use to keep warm? Do you have high maintenance and repair costs for your HVAC systems? Or, are you worried that your investments in heating and cooling systems are not sustainable in the long-term?
Instead of repairing and replacing components prematurely, you can, instead, take preventive measures that need small investments but give great effect – exactly what TTM’s products for fluid processing are about. Our products increase the energy efficiency in the system fluids, reduces corrosion and prolongs the lifetime of the components.
Feed efficiency is not an obvious matter
Effective flows to all parts of a heating and cooling system are a prerequisite for good energy efficiency. The water contains gas; oxygen, nitrogen and, in some cases, carbon dioxide. The gas content is affected by pressure and temperature, the higher the pressure and the lower the temperature, the more gas the fluid can carry.Water that contains gas, when the pressure and temperature varies, forms gas bubbles, which disrupts the flow and lowers the efficiency of heat exchangers, pumps, radiators, fan coils etc.
The disruptions in flow are usually experienced as difficulties in obtaining heating, or cooling, out to all parts of the HVAC system, where varying pump capacity and difficult to balance systems are common symptoms.
Already at about one gram oxygen per liter, the corrosion process starts. In system fluids without a vacuum degasser, the corrosion proceeds quickly and forms dirt and magnetite that “consume” the system components from within.
The aim of processing the fluid using vacuum degassing is to reduce the gas content to a level where corrosion stops and the system fluid regains its optimal energy carrying properties.
Degas the system fluid and reduce the costs by vacuum degassing
The particle content in the system fluid impairs all systems, regardless of system components. Increase the lifetime of the system, lower the operating costs and reduce the energy demand by continuous vacuum degassing.
In normal cases, your heating and cooling system is filled with ordinary tap water, which contains gases such as oxygen, nitrogen and carbon dioxide. These gases substantially impair your system’s useful life, economy and performance.
At low temperatures and high pressures, gases are bound to the fluid and cannot be released using standard air separators. To release the gases under these conditions it requires treatment with TTM NoXygen® vacuum degasser.
The easy way to degas the system fluid!
The method is based on filtering and vacuum degassing the system fluid. First, you analyse the fluid visually, take water samples and measure the oxygen concentration, pH, conductivity and carbon dioxide concentration (CO2).
- 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.
- Filter with MAG 76 or MAG 250
Magnetite and particles are removed efficiently with TTM MAG 76 together with TTM NoXygen®.
- For heavily soiled systems TTM MAG 250 is used to remove magnetite and other particles efficiently.
- Pressure equaliser
In systems that use pump expansion, TTM Offset is used together with TTM NoXygen® to counteract pressure variations.
Replace the fluid if the conductivity is higher than the tap water’s, if the fluid smells bad, is yellow/brown, has low pH and/or foams. With TTM Refill, the fluid replacement takes place during operation.
