1.3 Functions

The following functions are - in some instances optionally - included in the boiler guard:

Gas separator:
The outgassing is based on three physical principles:
• Deflection on the deflector plate acts like a centrifuge.
• Reduced flow speed decompresses the liquid (Bernoulli), which
causes microbubbles to form from the dissolved gasses.
• The supply water flows through what is referred to as the
flow straightener: a bundle of several small pipes. The micro-
bubbles gather on the large surface area and once they have
reached a certain size, they release and rise to the automatic
air vent.

Dirt separator:
Return water from the heating circuit flows slowly through the
boiler guard. Solid particles (sludge) sink to the base. Specific
deflection devices support this cleaning effect. The accumula-
ted dirt can be flushed out through a fill and drain ball valve.

Magnetite separator:
A stack of magnets is contained within a brass case. Mag-
netic particles (rust) from the heating circuits accumulate on
the outer surface of the brass case. Pulling out the stack of
magnets causes the particles to fall to the base from where
they can be flushed out along with the accumulated sludge by
opening the fill and drain ball valve. Note: On the base, there is
an additional ½" coupler with plug for an additional magnetite
separator or an RL sensor.

Hydraulic diverter:
Boiler guards painted orange contain a perforated plate instead
of a sealed separation between the supply and return line
chambers (boiler guards without a hydraulic diverter are pain-
ted black). This hydraulically decouples the boiler circuit from
the heating circuit, allowing different volumes of heating water
to circulate upstream and downstream from the hydraulic
diverter. Note: Deflections increase the length of the flow path
in the short end section. This stops the inflowing water from
affecting the other (decoupled) heating circuit, despite the
compact construction height.

a Supply sensor:
An immersion sleeve ø 9.7 mm is integrated in the boiler
guard for the sensor for the heating circuits.
