INTRODUCTION
WELCOME: Congratulations on your purchase of the world’s smallest office Liquid
Nitrogen Generator, the Elan2Digital. Being the latest generation of award winning
Liquid Nitrogen generators offered by MMR, the Elan2Digital boasts increased
production rates, a smaller foot print, quieter operation, and a digital
microprocessor.
The Elan2Digital offers a new user friendly interface; including self-management
and error checking to improve overall efficiency, uptime, and production. By
minimizing user intervention, and with the provision of intelligent feedback
and control, the Elan2Digital will offer years of quiet, clean, on-hand Liquid
Nitrogen produced directly in your office.
INTENDED USE: The Elan2Digital systems are intended for indoor use only, for the production of
Liquid Nitrogen. Because the Liquid Nitrogen generated does not get handled by complex industrial
processes or trucks, it is extremely clean. This makes it an ideal solution for research applications,
clean rooms, tissue biological sample preservation, or clinical cryosurgical applications.
PRODUCT OVERVIEW: The Elan2Digital produces Liquid Nitrogen straight from the air direct to the
user in their office. This is made possible by advanced Nitrogen separation and closed-cycle
Kleemenko cooler technology. When put together a production rate of 1Liter every 3-4 hours of
high purity, clean Liquid Nitrogen is possible. The new built in self-management system provides
peace of mind that the Elan2Digital is always performing at its peak, and Liquid Nitrogen is always
available on-demand and on-time.
The system is comprised of:
Elan2Digital Liquefier
Whisper Air Compressor

SAFETY
LIQUID NITROGEN SAFETY: These Liquid Nitrogen generators have been designed with the highest
level of user safety in mind. They are also designed to minimize direct handling of Liquid Nitrogen
by the user. However care must be taken to ensure no contact is made with the cryogenic fluid
during Liquid Nitrogen removal from a leak or splash.
HANDLING: Never allow any unprotected part of the body to touch un-insulated pipes or vessels
which contain cryogenic fluids. The extremely cold fluid can cause severe burns if even momentary
contact with human skin is made. Always wear adequate eye protection and gloves when handling
cryogens.
CONTAINMENT: Never carry Liquid Nitrogen in a vessel not properly suited for Cryogenic Fluids.
MMR assumes no liability for injuries caused through improper handling or use of the provided
Cryogen Storage Vessels (Dewars). MMR has thoroughly tested and approved the following
Cryogenic Storage Vessels (Dewars) for use with this system:
Brymill CRY-AC Series for cryosurgery
MVE Dewars from PrincetonCryo
RISK OF EXPLOSION!
NEVER CAP OR SEAL A STORAGE VESSEL (DEWAR) FOR LIQUID NITROGEN THAT DOES NOT HAVE
ADEQUATE VENTILATION HOLES OR A PRESSURE RELIEF DEVICE.
SPECIFICATIONS: Liquid Nitrogen is a colorless, extremely cold liquid and gas (-198°C). It can cause
rapid suffocation when concentrations are sufficient to reduce oxygen levels below 19.5%. Contact
with liquid or cold vapors can cause severe frostbite. Cold vapors in the air will appear as a white
fog due to condensation of moisture. While this may indicate the presence of the gas it should not
be used to determine its concentration in the atmosphere. Oxygen concentrations must be
monitored in the release area. All cryogenic liquids produce large volumes of gas when they
vaporize. One volume of Liquid Nitrogen will expand to produce 696.5 equivalent volumes of gas.
MSDS-OSHA: Not established
ACGIH: Simple Asphyxiate
CAS NUMBER: 7727-37-9

LOCATION RECOMMENDATIONS
CHOOSING A LOCATION: To ensure optimal operation and ongoing performance of the system, the
following guidelines must be met:
Room temperature should not exceed 72°F
Well ventilated
The room should be free of dust and exhaust from other instrumentation
The room should be of low humidity (<40% Relative Humidity)
A stable dedicated power source (extension cords should be avoided)
HANDLING:
Never tilt, tip, or lay the system down. Never move or JAR the unit when running
Never power down the system immediately (run in “STANDBY” for 15 minutes first)
Never block or obstruct the vents; doing so will overheat the system and in some cases cause
permanent damage. Temperature recording devices have been implemented for warranty
purposes

QUICK SETUP
CONNECTING THE AIR COMPRESSOR TO THE LIQUEFIER:
1. Connect Air Hose from Air Compressor to Liquefier; hand tighten only
2. Connect Air Compressor Data Cable from the Air Compressor to the Liquefier
3. Connect both Power Cables from Air Compressor and Liquefier to suitable wall outlets
4. Turn on Air Compressor and Liquefier
5. Switch the device to “RUN” 11
SETTING THE CLOCK (IF NECESSARY): The clock is factory set, and is displayed when the unit powers
up, followed by the day. Press “RESET” 13 to view the clock at any time. See page 8 if the time or date
are incorrect. The clock is used for automatic maintenance, which takes place at 9pm every Saturday
night.
TESTING THE AIR SUPPLY: With the unit running, press and hold the “Test Air Pressure” button 14 on
the rear of the unit. Over a period of 30 seconds, the “Pressure” 10 should rise to a minimum of 90PSI.
if it doesn’t reach 90PSI, check the Air Hose connections for leaks.
DEFROST: Each time the unit starts up following installation, a power failure, or resetting of the unit, a
90 minute defrost is commenced. This can be cancelled at any time by pressing the “DEFROST” 8
button on the front panel. Subsequent defrosts can be started if required by pressing and holding the
“DEFROST” button for 2-3 seconds.
VIEWING SENSOR VALUES: When the system is not defrosting pressing the “MODE” button 6 will
toggle the sensor value as indicated by the lights 1.
COOLDOWN: Once defrosting has completed, the refrigeration system will become active and will
begin to cool down the Liquefier. This can be monitored by watching the “Cryo Temp”. See Viewing
Sensor Values. When the temperature has reached 77K, cool down is complete and production will
begin. This should take about 30 minutes.
LOCKING AND UNLOCKING: The “LOCK” feature 9 is a security device to stop unwanted dispensing. If
the system is unlocked and the Dewar is in place, dispensing is enabled indicated by the “Ready” light
