GLOSSARY TERMS
AIR PRESSURE:
The pressure coming from the Air Compressor (90-100PSI; 120PSI max).
CRYOGEN:
A substance used to produce very low temperatures.
CRYOGEN STORAGE VESSELS:
Referred to as a Dewar or Flask.
CRYO TEMP:
The temperature inside the Liquefier expressed in Kelvin units (77K when cold).
COMP TEMP:
The temperature of the Refrigeration Compressor Casing expressed in degrees
Celsius.
CONSOLE:
A Serial Interface, system telemetry is outputted every 10 seconds. 9600,8,N,1
DEFROST:
A 90 minute timed process in which the system warms up and evaporates moisture.
DEWAR:
A containment vessel for cryogenic fluids.
DISPENSE:
The process in which LN2 is transferred to the user.
FLOW:
The measured flow od N2 gas traveling through the Liquefier indicating normal operation.
LIQUEFIER:
The part making up the Elan2Digital responsible for converting a gas into a liquid.
LN2:
Abbreviation for Liquid Nitrogen.
LOCK:
The system will produce internally until FULL but external transfers will be prohibited.
N2:
Abbreviation for Nitrogen Gas.
POWER CONSUMPTION:
The power (Watts) consumed by the Liquefier during operation.
PSA:
Pressure Swing Absorber, the part responsible for drying the air to very low levels.
REFRIGERANT:
A substance within the closed cycle refrigeration system used for cooling.
RUN:
Normal operation.
SCALE:
An external scale for indicating storage Dewar contents.
STANDBY:
The system will remain at room temperature and not produce. The fans an Air
Compressor will shut off after 15mins. Pressing the “DEFROST” button will keep Air Compressor on.
TRANSFER:
The process in which LN2 is transferred from the Liquefier external Dewar.
USER INTERFACE:
The front control panel containing the function buttons and display.
