– Service interval display
The target value for the flow rate is freely selectable. A suitable tubing set with
connectors for the CultiBag RM are included in the package. An integrated pressure
sensor controls the overpressure in the CultiBag RM and sets the aeration to achieve
a max. of 30 mbar of overpressure.
Only available with the optional aeration module.
For the air intake, you can select either an integrated air pump that supplies the bag
with room air or a compressed air supply on the rear side of the rocker housing for
external air intake. The overpressure in the CultiBag RM is monitored via an
integrated pressure gauge (for details, see
You must observe the gas pressure values listed in the operating instructions.
This is the only way to ensure proper functioning of the system.
y Room air supply: via a membrane pump which compresses the air at the rear
"AIR IN" connection
y Compressed air: integrated pressure regulator for connection to an external
compressed air source, + 1.5 bar
y Quick release coupling: for the direct connection of a rigid tube (AD 4.0 mm)
y CO integrated pressure regulator for connecting to an external CO2 source.

1.5 bar quick release coupling for the direct connection of a rigid tube (AD 4.0 mm)
y The gasses used must be dry as well as dust and grease free.
Use a filter if necessary.
Mass flow controller for flow speeds of 50–1000 ml/min;
Reading accuracy ± 5 %
The CO concentration controller has a target value range of 0.8 % – 15%, the display

8–42 ± 1 rocker movements/min, can be set on the display
4–10°, ± 0.3°, can be set on the display.
PLC-programmed PID controller. The heating plates can be used to heat an individual
2L or 10L bag on one side or two 2L or 10L bags or one 20L or 50L bag on both sides.
The temperature of the heating panel can be controlled via the touch screen on the
front of the device. Only room air is used for cooling. No additional device is required.
A heating | cooling function with water cooling is available as an option for the
