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