3/4" NPT Female DISCAL Air Separator for Solar Heating

The removal of dissolved gases from a solar primary circuit is an essential process in a solar heating system. The presence of dissolved oxygen in a solar circuit causes rapid localized corrosion in collectors and heat exchangers. Carbon dioxide will dissolve in water, resulting in low pH levels and the production of corrosive carbonic acid. Low pH levels in a solar circuit causes severe acid attack throughout the solar heating system. While dissolved gases and low pH levels in the solar circuit can be controlled by the addition of chemicals, it is more economical and thermally efficient to remove these gases mechanically. This mechanical process is known as air separation and will increase the life of a solar heating system dramatically.
