CRB AUTOMAT
Description
Compressor controlled pressurization units, classified as a dynamic pressurization system for heating and
cooling water systems. It requires an auxiliary power source for its operation.
They are controlled by a compressor and allow to maintain steady pressure in the system, by compensating
volumetric changes suffered by the fluid, as a consequence of temperature variations in the system.
CRB AUTOMAT is formed mainly by a control unit (Compressor & controller) and an expansion vessel.
Expansion tank is fitted with a bladder to divide the vessel between air and water side.
CRB AUTOMAT provides the following safety features:
• Optimization of pressure maintenance.
• Reduced corrosion damage due to oxygen removal.
• No direct intake of air thanks to a regulation of the pressure maintenance.
• No circulation issues caused by free bubbles in the water system.

Application
Increases and decreases in water volume are continuous in heating and cooling systems due to temperature
variation. When temperature raises, the pressure in the system increases. As a consequence water level in water
side of the expansion vessel changes. That increase is absorbed by the expansion vessel. Pressure differences in
air side is showed in display.
On one hand, pressure sensor measures air pressure and transmit to the control unit. Control unit compares the
measured value with the programmed nominal value and if the pressure increases, the solenoid valve will be
activated to reduce the pressure until reaching set values.
On the other hand, when temperature in system drops, pressure in the air side change. Control unit compares the
measured value with the operative or set point pressure value and if pressure decreases the compressor will be
activated until reaching set values.
A. Temperature increase
Unit contains a small amount of water. Unit is
in res
t
B. Temperature increase
Water volume and pressure system rises. Controller
responds to this by discharging air from the vessel and
as a result, the ex
p
ansion water flows into the bladder.
C. Full power
By storing increasing amounts of water in the
vessel, controller keeps pressure system at a
constant level. When system has warmed up
completely, vessel will be operating at almost
its maximum ca
p
acit
y
.
D. Cooling down
When water volume and thus pressure system
decreases, controller will respond by increasing the air
pressure in the vessel with displacement of water back
into the subsystem as a result. This restores

q
uilibrium in

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

Pre-Comissioning
Determine the position of the expansion vessel. It must be placed on a level ground or surface, or failing that,
proceed to level it correctly, in order to ensure the proper functioning of the vessel. It is important to do this
correctly so that the volume sensor can detect a third of the weight of the vessel and therefore, indicate the correct
volume. If the delivery includes more than one vessel, the "secondary" vessel does not have a volume sensor.
Check that the data collected on the sticker attached to the expansion vessel are in accordance with the purchase
specification and they are suitable for installation. Before proceeding with installation, make sure that the volume
of the expansion vessel has been calculated by authorized personnel, technical staff has an appropriate profile and
training in the facilities of this type of equipments. The local regulations for the operation of the expansion vessels
must be considered. The installation and operation must be carried out in accordance with good practices by
professional installers and authorized technical personnel.
The expansion vessel must be installed in an enclosure protected from the weather with necessary dimensions to
facilitate the inspection of the vessel from all parts, being the control unit, air filling valve, the connection sleeve
to the installation and label accessible. It should be located in the boiler room, well ventilated and with an ambient
temperature of 5 to 40 ° C. Check that there is enough space around the vessels and the pressure maintenance unit
to facilitate future maintenance and service work. It is not allowed to isolate any part of the equipment.
Make sure that the equipment has no marks, dents or signs of tampering.
Do not place any valve whose closing may unintentionally cancel the operation of the expansion vessel. It is
recommended to install traps and / or air separators to avoid air accumulation.
Avoid direct radiation on the expansion vessel to protect the membrane from possible excesses of temperature.
In closed heating systems, a warning should be visible next to the expansion vessel to indicate people who are in
danger because they are near surfaces with high temperatures.
Mounting air hose: If the equipment includes an extra or secondary vessel, mount the T-tube supplied with the
hose set, in the main vessel and the elbow coupling in the sleeve located in the upper part of the secondary vessel
(air side). If it is necessary to cut the connecting air hose of the two vessels, main and secondary use a sharp knife.
If is used other ripping tool, plastic chips can be appear and can enter in solenoid valve or other sensitive places
and cause unnecessary operating anomalies.
Attention: The pipes must be dimensioned and installed in accordance with the specific requirements
according to local and national regulations. Remember that the connection of pipes or equipment with the
system may cause additional stress to the device. Ensure a stress-free installation of the pipe connections
between the ex
p
ansion vessel and the s
y
stem.

Being the valve that connects the expansion vessel with the closed heating system closed, install the expansion
vessel to the heating / cooling system using the flexible hose with elbow supplied. The angled end of the flexible
hose is screwed into water connection of the expansion vessel located in the lower part of the vessel and the
straight part of the flexible hose to the heating system.
Being closed the water passage valve between vessel al heating system, check that the manual air bleed valve on
the top of the vessel is closed through the hose fitted on the top cover. Also check that the valve in the lower part
of the tank (condensation water) is closed. It is preferable to fill the system with the valve closed.
Commissioning is easier when the vessel is empty.
Attention: If using a secondary expansion vessel in addition to the primary vessel, make sure that all
vessels have the same type and dimensions.
Before proceeding to parameterize the control unit, confirm that:
- The tank is empty of water.
- The heating system is completely filled with water.
- The control unit is connected to the expansion vessel.
- The water connections of the tanks to the system of facilities are established.
- The valves for emptying the tanks are open.
- The electrical connection has been created in accordance with applicable national and local regulations.
