Changeable Membrane heating Series Tanks

IT IS WELL KNOWN THAT WATER CAN NOT BE COMPRESSED

Taking that as a princible, the volume of the system’s water
increases along with the temperature increase in the closed
circuit heating&cooling systems. As the increasing water
volume can nor be compressed, the excoss of the water
has to be compansated into the closed curcuit system. For
this reason, the most common way to compensate the
excess the water is to add an expansion tank to the system.
When comparing, NIAGARA heating series expansions
vessels in use at closed circum system to open circul
systems. the expansions vessels provide great advantages
to the svstem:
• The outside going water has to be added back
into the system each time in the open circuit systems.
• Corrosion is quite possible in open circuit systems
because of the oxygen penetrating into
the system
• The installation of the expansion vessels is much easier
than the open circuit systems
