Operating and service manual, Controlled Atmosphere
Preface
The Star Cool CA is a controlled atmosphere system designed to prolong the shelf life of perishables by regulating the internal atmosphere of the container. The container’s atmosphere obtains the
desired gas composition based on entered set points for O2 and CO2 via the controller.
The desired atmospherical composition of the gas serves to lower the respiration of the perishables,
and thereby providing a prolonged shelf life.
ATTENTION! Due to regulation of the cargo atmosphere during transport, oxygen level
may be low and/or carbon dioxide level high inside the container! Please check gas levels
and flush with fresh air before entering and unloading. Exposure to low oxygen/high carbon dioxide may cause loss of consciousness and suffocation.

The basic principle is that the fruit will generate CO2 from O2 via respiration. This will increase the
CO2 level and decrease O2 level inside the container. When the CO2 level reaches above the CO2
set point the vacuum pump will activate and evacuate CO2 with the selective membrane. In case
the O2 level goes below the O2 set point the fresh air valve will open and let in ambient air (20,9%
O2). This described mechanism will regulate the gas concentration within the container as illustrated
below:

Warning
Due to low oxygen levels inside the container, ventilation is necessary before entering, either
for repairing the unit or unloading. Stay away from doors while venting.

1. STD function test
2. CO2 sensor test
3. O2 sensor test
4. AirEx motor test
Operation
Set points:
CO2 and O2 set points are entered in the menu structure O07 an O08.
O2 levels below 2% can not be entered.
CO2 levels below 5% can not be entered.
Level readings:
O2 and CO2 concentrations can be viewed in the menu structure I03 and I04. The membrane pressure can be viewed in the menu structure I18 - this displays the vacuum level created. Vacuum
pump oil temperature can be viewed in the menu structure I36.
Manual mode
The AirEx motor can be activated in manual mode in the menu structure M09.
0%: Valve closed
100%: Valve open
10
Operating and service manual, Controlled Atmosphere
The vacuum pump can be activated in the menu structure M10. Activating the vacuum pump should
result in a pressure drop which can be viewed in the menu structure I18.
Only manually activate the vacuum pump when absolutely necessary! The vacuum pump
is not pre-heated if manually activated - this can cause damage to the vacuum pump over
time.
CA curtain
When CA is activated a CA curtain must be installed. Ensure the CA curtain is installed in accordance with the guide included with the CA curtain.
Vacuum system test
Note: BE AWARE OF HOT SURFACES - when handling the vacuum pump.
The vacuum system consists of a membrane connected with a hose to a vacuum pump. Below you
will find a step-by-step method to determine the root cause of a vacuum fault. Please be aware that
there can be more than one problem in a vacuum system, and you might need to go through the
tutorial several times to eliminate the problem.
A vacuum fault alarm can be caused by a single or a combination of the following:
1.
2.
3.
4.
5.
Insufficient amount of oil in vacuum pump
Defective pressure transmitter
Defective or leakage in vacuum pump
Leak in fittings or connections
Leak in membrane
Method to determine the cause:
1.
2.
3.
4.
Check oil level in the vacuum pump. Refill if needed.
Go to menu structure M10 and turn on the vacuum pump and verify that it rotates in the right
direction. If vacuum pump does not activate, see section
“Simple trouble shooting vacuum pump / controller module” on page 12. If vacuum pump acti
vates proceed to 3.
Disconnect the vacuum hose at the vacuum pump and plug the vacuum pump inlet.
a. If the pressure is above 30 mBar, proceed to 4
b. A pressure below 30 mBar indicates the vacuum pump is OK, proceed with the following:
Connect the hose to the vacuum pump again and ensure the connection is tight.
Install a manometer at the transmitter inlet and ensure the reading is similar to the display
reading. If not, the pressure transmitter is defect. If pressure is OK, change the vacuum pump.
Go to menu structure M10 and turn on the vacuum pump.
If the vacuum fault alarm is still present - 2 options from here:
If unit is in operation with cargo: Do nothing! Either the membrane or the connection to the
membrane is leaking. It is not possible to correct this fault during operation, due to low oxygen
level inside container.
Do not enter the container - including opening the service hatches - when
oxygen level is below 20.9%.
Empty container: Disconnect the vacuum hose at the membrane and plug the hose.
Go to menu structure M10 and turn on the vacuum pump.
If readings are:
- Above 30 mBar: ”Problem surrounding the vacuum hose” on page 12
- Below 30 mBar: ”Problem located at membrane” on page 12
