Liquid Nitrogen Plant

Product Advantages

1 Each unit machine is skid-mounted construction, connected by fixed-size short pipe, the whole set of plant with all pipes and valve together are delivered to the User’s site, the Users needn’t to buy any additional spare part by themselves, we ensure the plant’s perfect and integrate.

2 The User only need prepare well the workshop, workshop ground and crane.

3 Adopting liquid pump inner-compress technology, we can produce high-quality nitrogen with purity range in 99-99.999%.

4 Small volume, space small, the complete set of plant only occupied 125M2(25m×5m).

5 Complete set of plant is installed without foundation, it has following advantages: stable running, easy operation, convenient maintenance, without easy-damaged spare parts within two years.

6 To ensure all valves’ quality, we adopt the best-quality valve in Air separation Industry produced as the cold-valve in the Rectification column. We adopt stainless steel valve as the Purifier valve, and also install thermostability mat in the stainless steel valve to ensure that the valve is of little wear, no cooling leak, no gas leak, long life in the long-term running.

7 Advanced technology adopted in each unit can reduce power consumption greatly, and save electricity fee at the same time.

8 Complete set of plant could be transported by car easily to suburban and faraway district. That can satisfy customer’s nitrogen requirements in time in different areas.

9 It only takes about 15-30 days for the installation and commissioning.

10 The pipes used in the Purifier, including the connecting pipes between Purifier to Rectification column are in the conditions of cold-heat changing alternately. The temperature changes range from 5℃～200℃. When temperature is low, condensing-water corrode pipe, while the temperature is high, the pipe oxidized seriously. To ensure the life of connecting pipe, and safety of plant, we have made heat insulation treatment on all the pipes.

11 To ensure the safe running of the plant, we equip four-stage pipe oil-filter to ensure that no oil can enter purifier and rectification column. The pressure-difference meter in the four-stage pipe can also show the oil quantity to inform us to change the filter core, ensure the safety of follow-up plant. All filters are equipped with pressure-difference meter, we can judge the degreasing effect and the best time to change filter core, in this way we can prevent oil entering system after the filter core lose efficacy.
