Advanced Control System
1. HMI human-machine interactive touch screen, display temperature, liquid level, temperature curve and alarm information.
2. Important events such as temperature, alarm, liquid nitrogen fill, can be checked, and can also download through USB disk.
3. Various alarms, and the alarm information can be stored and downloaded through the USB disk.
4. Operating data, such as temperature and liquid level, can be stored for up to 10 years.
5. Optimized structure design to achieve the best sample storage density and save space.
Features
1. Multiple capacity freezers, from 175L to 600L, 2.0ml vials storage capacity from 10,000 to 40,500.
2. Excellent temperature uniformity and stability, enabling samples to be stored at controlled cryogenic environment.
3. Excellent vacuum performance and structural design ensure minimum liquid nitrogen consumption and lower storage costs.
4. Advanced temperature, liquid level monitoring and alarm system, and can realize remote monitoring.
5. Automatic supply of liquid nitrogen, safe and labor-saving.
6. 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.
7. Manual filling available under special circumstances.
8. The optimized mechanism design realizes high-density storage to save space.
Humanized Design
1. Defog function, easier to find samples and shorten lid opening time.
2. The remote alarm interface can be connected to the central alarm system.
3. Optional backup battery in case of power failure.
4. Optional vacuum jacketed hose for lower liquid nitrogen consumption.
Why W Series?
1.High density storage
Compared with similar products, W series 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.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.
3.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.
4.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.
