Different industries have different temperature requirements for cryogenic cryostats. Of course, there are many types of cryogenic cryostats. The refrigeration methods used in different industries are different. LNEYA uses compressor refrigeration to achieve refrigeration. The effect is similar to or better than liquid nitrogen cryogenic cryostat.
However, there are still customers who use liquid nitrogen cryogenic cryostats, and customers who encounter power failures when they encounter them do not know how to solve them.
One is the frequent power outage. If the power is cut off frequently, then there will be some damage in the next time the liquid nitrogen cryogenic cold box is started. The compressor is out of the working state, then the compressor will be on the compressor. There is damage. If the power outage is not used for a long time, it is also easy to cause the pipeline inside the liquid nitrogen cryogenic cold box to be damaged and the pipeline refrigerant to leak. Obviously, the impact is relatively large and prone to failure.
In two cases, it is not energized for a long time, because it is cold in the northern part of the winter, so many customers cut off the electricity of the liquid nitrogen cryogenic low temperature box
. So what can you do in the end? If the refrigerant is not energized for a long time, the refrigerant will be converted from a gaseous state to a liquid state during operation, and it will be very easy to cause damage to the pipeline, which will lead to leakage. That is, leaking refrigerant.
Then don't frequent power outages. If there is no power failure when the compressor is not working, if there is a sudden power failure and then the power is turned on immediately when the compressor is working, the chance is caused by the large pressure difference between the two ends of the compressor. The liquid nitrogen cryogenic cold box has no way to work, so the thermal protection is stopped. If the protection zone of the liquid nitrogen cryogenic cold box is damaged, the motor will be burnt if it is serious.
It seems that this situation is also more complicated. If you feel that the liquid nitrogen is cold and cold, you can choose LNEYA cryogenic low temperature box or ultra low temperature freezer, and the cooling effect is good.
