HC Pressurisation and Degassing Units Standard Range

For systems larger than 4MW, or with higher static heights than 9.2 bar, contact us here

The units do not use a membrane pressure vessel, the expansion is at atmospheric pressure which not only minimises the expansion vessel size, but also allows the pressure step de-aeration process. No membrane in the vessel mean no gas pressure to maintain, no membrane to replace.

Free and dissolved gases or air bubbles, formed during system filling and absorbed from parts of the heating system are removed using this unique de-aeration device. Opening a mineral water bottle produces gases which were dissolved in the water, the Olymp Automat uses the very same principal to remove from the installation all aggressive and destructive gases even from remote areas of the system. See Henry's Law - adiabatic gas separation.
