DISCALAIR devices are used in air-conditioning systems or in the phase of
filling and starting solar panel systems to discharge even large quantities of
air that has formed in the circuits. This function is performed even when there
is considerable pressure thanks to the special geometry of the discharge
mechanism, which is identical to the one on DISCAL 551series deaerators.
This particular series of automatic air vent valves has been specifically
designed to work at high temperature with a glycol medium, which is typical of
solar heating systems.
