The Caleffi Solar Systems Safety Relief Valve handles the essential removal of gases from a solar primary circuit in a solar heating system. The presence of dissolved oxygen in a solar circuit caused rapid localized corrosion in collectors and heat exchangers. Carbon dioxide will dissolve in water, resulting in low pH levels and production of corrosive carbonic acid. The removal of these gases is known as air separation and will increase the life of a solar heating system dramatically.
