Air separation efciency
DISCAL air separators continuously remove entrained air in hydronic
systems with very high separation efficiency. The amount of air removed
from a system varies depending on fluid velocity and temperature. As
illustrated on the graph, at the 4.0 feet per second fluid velocity, all the
air artificially introduced into the system is gradually eliminated during
normal system operation by the DISCAL air separator. In conditions
where the fluid velocity is slower or the temperature of the fluid is higher,
the amount of air separated is even faster.
