air which is continuously formed. The units should
preferably be installed after the boiler and on the
pump suction side, as these are the points where the
formation of micro-bubbles is greatest. DISCAL air
separators must be installed vertically. In installation
conditions where inspection is not possible, it is
recommended that the venting valve cap is replaced
by a Caleffi Code nr. 59681 hygroscopic safety vent.
The maximum fluid velocity recommended at the unit connections is
~
4.2 f/s.
The following table shows the maximum flow rates to comply with this
condition.
