Product advantages:
| High-density storage | Compared with similar products, it occupies a small area and stores more samples, which can save space and reduce the storage cost of unit samples; |
| Excellent temperature uniformity | Vacuum insulated stainless steel box structure, high vacuum coverage, to ensure excellent thermal insulation and thermal insulation performance |
| Stable opening temperature | The innovative box cover and the excellent design of the small opening with an offset neck can greatly reduce the volatilization rate of the liquid atmosphere. Even if the cover is opened for a long time, the temperature inside the box can still be kept constant, and the temperature of the box can be maintained no higher than -150CC within 48 hours; |
| Advanced temperature monitoring system | The monitoring system based on a microprocessor and upper and lower double-platinum resistance temperature probes can display the highest and lowest temperature in the box in real-time with an accuracy of ±1 c. The user can set the alarm point by himself. It has the option of alarm mute; |
| Automatic perfusion liquid nitrogen and liquid level monitoring system | Based on the differential pressure sensor and the liquid level monitoring system, the liquid level is displayed in real-time to ensure the safety and reliability of the automatic filling process of liquid nitrogen. The 10-inch LCD screen can display parameters such as top temperature, bottom temperature, liquid level, and operating status; |
| Hot gas bypass | The hot gas bypass can remove the room temperature ammonia gas in the pipeline before the liquid nitrogen is injected to ensure that only ultra-low temperature liquid nitrogen is injected into the tank, which avoids the temperature fluctuation of the liquid nitrogen tank during the liquid addition process, which affects the safety of the sample and reduces the extra consumption of liquid nitrogen; |
| Multiple humanized designs | Stainless steel auxiliary workbench can be used for temporary placement of freezer racks to speed up sample picking and placing: the folding steps of the body reduce the operating height, which is convenient and labor-saving for picking and placing. Alternate openings in the inner swivel tray make it easy to find accidentally dropped samples. |
Packing with wooden box and shipping method can be negotiated.

Q: Application of insulated welded cylinders (Dewars)?
A: AUYAN supplies dewars to safely contain liquefied gases such as nitrogen, oxygen, argon, and carbon dioxide, which are for industry and commerce use. These gases are stored at extremely low temperatures and in a liquid state.
Q: How many different specifications of insulated welded cylinders (Dewars) does AUYAN have?
A:We produce Insulated Welded Cylinders (Dewars) with 6 different specifications: 175 L (Net Capacity 161 L, 67 kg*), 195 L (Net Capacity 179 L, 75 kg*), 210 L (Net Capacity 193 L, 81 kg*), 410 L (Net Capacity 377 L, 158 kg*), 450 L (Net Capacity 414 L, 173 kg*), 499 L (Net Capacity 459 L, 192 kg*)
*The weights above are counted under the circumstance that the density of the cryogenic liquid is 0.42 kg/L.
Q: What is the ideal working pressure of the LNG Vehicle cylinder?
A: The ideal working pressure is 0.8 Mpa - 1.2 Mpa, while the nominal working pressure is 1.59 Mpa.
Q: What is the warranty of your Products?
A: The warranty for the vacuum of equipment is 3 years from the date of sale.
All components come with a limited 1-year manufacturer warranty on defects in material or workmanship from the date of purchase to the original owner.
