The operating pressure in the vessel allows for withdrawing
the liquid gas.
Vessel name Apollo
®
maximum operating
pressure
1,3 bar
The safety valve limits the maximum operating pressure.
Should the pressure in the tank not be sufficient for the
withdrawal operation, it can be increased by opening the
pressure build-up valve.
Prior to pressure build-up:
• Check the EK Siphon for tight seat.
• Adjust the operating pressure only as high as
required.
Pressure Build-up
1. Close the waste gas/overflow valve.
2. Close the filling/withdrawal valve.
3. Slowly open the pressure build-up valve.
4. Watch the pressure gauge.
5. Close pressure build-up valve when the desired pressure is
reached.
Continuous Withdrawal under constant Pressure
1. Slightly open the pressure build-up valve.
2. Close the pressure build-up valve when the desired
pressure is reached.
3. When starting with the withdrawal, watch the pressure drop
at the pressure gauge.
4. Open the pressure build-up valve is such a way that the
desired pressure remains constant.
Note
• Avoid blowing-off of the safety valve.
• Frost formation on the vessel bottom is operational.
Close the pressure build-up valve prior to finishing
the withdrawal process.
A pressure control valve is recommended for
continuous withdrawal. This item has to be indicated
separately on the purchase order. Retrofitting is
possible.
