CRB AUTOMAT
Compressor
Air supply
When water in the system is heated,
pressure in the system rises. If the
nominal pressure at the controller is
exceeded, the solenoid valve opens
and discharges air from the vessel.
It allows water to flow into the
expansion vessel and the water
pressure within the system drops up
to nominal pressure.
As water cools, water pressure in
the system drops. If pressure in the
system drops below the nominal
pressure, compressor delivers air
into the expansion vessel up to
reach the nominal pressure
Overview CRB AUTOMAT
Replaceable bladder
Bladder stores water. It
allows to divide air side
from the water side
Flexible connection R1”
for the expansion line
Load cell
It measures the water level
inside the expansion vessel.
If water level rises over a
limit occurs ”high water
level alarm”
If water level drops below a
limit, occurs “Low water
level alarm”
Expansion vessel
Compressor
controlled expansion vessel.
It allows to maintain steady
pressure in the system,
compensating
volumetric
changes suffered by the fluid,
as
a
consequence
of
temperature variations in the
system.
The air side of the expansion
vessel and the load cell are
connected to vessel control
unit.
Control unit-Touch screen
Pressure system integrated
control
It includes compressor, 7” touch
screen control unit with solenoid
valve, antireturn valve, safety
valve and pressure sensor.
Solenoid valve
opens
and
discharges air from the vessel.
Antireturn valve
avoids air going
in an opposite direction.
Pressure sensor
displays
continuous pressure in the
system.
Safety valves
protects expansion
vessel.
