Hydraulic characteristics
Flow capacity
The fluid velocity at connections for DISCAL
®
551 series air separators is
recommended to not exceed 10.0 f/s. Above this speed, heavy internal
turbulence and noise can occur and air and dirt elimination efficiency
begins to fall measurably. Optimal air elimination performance occurs
at fluid velocities of 4.0 f/s or less. See the flow capacity charts below.
Installation
DISCAL
®
units may be used in heating or cooling systems to ensure
the progressive removal of 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 for horizontal pipes must be installed
vertically. Flow direction of the DISCAL
®
air separator is bidirectional: flow
in either direction is permitted. In installation conditions where inspection
is not possible, it is recommended that the venting valve cap is replaced
by a Caleffi Code R59681 hygroscopic safety vent. The standard
replacement cap code is 59119.

®
