YDD series high-efficiency vapor phase liquid nitrogen storage system
provides the most ideal storage conditions for biological samples. The whole
series realize -190°C vapor phase storage.
Supported by LN2 automatic filling system and temperature & LN2 level
monitoring system, YDD freezers provide all-round protection toprecious sample,
assisting life science research and cell therapy applications.
Based on the actual needs of users, Banagee has innovatively optimized the
performance, structure and control system of the vapor-phase cryogenic freezer
to meet the user's highest standard of large-capacity vapor-phase cryogenic
storage requirements.
Advanced Control System
HMI human-machine interactive touch screen, display temperature, liquid
level, temperature curve and alarm information.
Important events such as temperature, alarm,liquid nitrogen fill, can be
checked, and can also download through USB disk.
Various alarms, and the alarm information can be stored and downloaded
through the USB disk.
Operating data, such as temperature and liquid level, can be stored for up to
10 years.
Optimized structure design to achieve the best sample storage density and
save space.
Features
Multiple capacity freezers, from 370L to 1,800L, 2.0ml vials storage capacity
from 15,600 to 94,500.
Excellent temperature uniformity and stability, enabling samples to be stored
at -190°C vapor phase environment.
Excellent vacuum performance and structural design ensure minimum liquid
nitrogen consumption and lower storage costs.
Advanced temperature, liquid level monitoring and alarm system, and can
realize remote monitoring.
Automatic supply of liquid nitrogen, safe and labor-saving.
The liquid nitrogen supply system is controlled by multiple solenoid
valves,which can effectively prevent the overflow of liquid nitrogen and sample
contamination caused by high LN2 level.
Manual filling available under special circumstances.
Compatible with vapor phase and liquid phase storage modes, users can choose
according to their needs.
The optimized mechanism design realizes high-density storage to save
space.
Humanized Design
Defog function, easier to find samples and shorten lid opening time.
After 48 hours of lid open, temperature in the freezer remains below -150°C
(according to the factory test standard).
The remote alarm interface can be connected to the central alarm system.
Foldable step for convenient operation & space saving. Optional backup battery in case of power failure.
Optional vacuum jacketed hose for lower liquid nitrogen consumption.
Why YDD Series ?
1.High density storage
Compared with similar products, YDD freezers have a small footprint and can
store a large number of samples. It truly realizes high-density storage, which
not only saves space, but also reduces the storage
cost per sample. Both horizontal and vertical rack systems available.
2.Excellent temperature uniformity
Vacuum insulated stainless steel tank structure, high vacuum coverage, to
ensure excellent thermal insulation performance. When samples are stored at
vapor phase, top level sample temperature is lower than -180°C.
3.Stable opening temperature
The innovative lid and vacuum insulated neck design reduce LN2 evaporation.
Even when the lid is opened for up to 48 hours, the inner temperature can remain
stable.
4.Advanced temperature monitoring system
The monitoring system based on microprocessor and platinum temperature probe
can display the maximum and minimum temperature inside the tank in real time
with an accuracy of ±1°C. The user can set the alarm point by himself, with the
option of alarm mute.
5.Automatic LN2 filling & level monitoring system
The liquid level monitoring system based on high-precision differential
pressure sensor displays the liquid level in real time to ensure the safety and
reliability of the automatic filling of liquid nitrogen. The color touch screen
can display: top temperature, bottom temperature, liquid level height, daily
liquid nitrogen consumption and other parameters.
6.Warm gas bypass
The warm gas bypass design can remove the high temperature nitrogen (gas) in
the pipeline before the liquid nitrogen is injected, so as to ensure that only
ultra-low temperature liquid nitrogen is injected into freezer, which avoids the
temperature fluctuation in the freezer & thermo shock to samples during
filling process,protecting the safety of samples.
We are a pioneering high-tech enterprise dedicated to the research, development, and production of advanced cryogenic liquid nitrogen | LN2 storage container systems.
