Function

Air and dirt separators are used to continuously remove the air and debris

contained in the hydronic curcuits of heating and cooling systems. The air

discharge of these devices is very high. They are capable of automatically

removing all of the air present in the system down to the micro-bubble

level. The DISCALDIRT

air and dirt separator also separates any solid

impurities in the system. The impurities collect at the bottom of the device

and can be removed through the drain pipe for the steel versions, to which

a separately sourced drain valve can be mounted, or drain shut-off valve

for the brass version. The circulation of fully de-aerated and cleaned water

enables the equipment to operate under optimum conditions, free from

noise, corrosion, localized or mechanical damage.

The DISCALDIRTMAG

™

air and dirt separator with added magnetic ring

removes both magnetic and non-magnetic particles continuously, featuring

a powerful removable external magnet around the body that removes up

to 95% of the ferrous oxide particles that can form in a hydronic system.

Insulation shells are available separately for ﬁeld installation for the brass

DISCALDIRT

and DISCALDIRTMAG

™

air and dirt separators.

Operating principle Brass DISCALDIRT Microbubble air separation The air and dirt separator uses the combined action of several physical principles. The active part is the internal element (1) and consists of a glass-reinforced nylon mesh for the brass DISCALDIRT and DISCALDIRTMAG™, or an assembly of concentric metal mesh ( 304 stainless steel ) surfaces. These elements create the whirling movement required to facilitate the release of micro-bubbles and their adhesion to these surfaces.

Construction details Replacement parts The DISCALDIRT and DISCALDIRTMAG air and dirt separator is designed to be maintained and cleaned without removing it from system piping. ™ ® The automatic air vent, located at the top of the device, has a long chamber for ﬂoat movement (2). This prevents any impurities in the water from reaching the seal seat. The noncorroding stainless steel pinned linkage and PP ﬂoat can be accessed by removing the upper cover (1).
PAGE 5
Insulation shells The brass DISCALDIRT 5460 series and DISCALDIRTMAG™ 5461 series can be supplied with the optional insulated cover, code CBN546002 series (purchased separately), to minimize heat loss. Removing insulation and draining impurities ® 1. Remove the insulation by taking off the bottom casing of the collection chamber ﬁrst, and if necessary, the top insulation casing later.

The process of air formation The amount of air which can remain dissolved in a water solution is a function of pressure and temperature. This relationship is governed by Henry’s law and the graph demonsrates the physical phenomenon of the air release from water. As an example, at a constant absolute pressure of 30 psi (2 bar), if the water is heated from 65ºF (18ºC) to 170ºF (75ºC), the amount of air released by the solution is equal to 1.8 gallons of air per 100 gallons of water.
