KDON-
Type Air Separation Plant
is a cryogenic liquid oxygen and liquid nitrogen producing machine which can produce high purity Liquid Oxygen or high purity Liquid nitrogen in different working condition or LOX+LN2 at the same time.One machine with multi functions, while providing customers with high-quality liquid products, it also saves costs for customers. Customers can adjust the production mode according to the actual liquid market conditions to meet market demand.
Product Parameters

Air compressor
is sprayed-oil screw compressor, box-body construction, it have low noise, whole machine gather gas, lubricate, water, electric, cooling and instrument to one, realize machine and electric become one body. Control system adopt PLC controller, touch-way panel may provide the supervision of all adjustment of parameter and critical running parameter, also have alternative Chinese and English liquid crystal display, have full protection function, may realize no-person operate.

Turbine Expander
Turbine Expander is combine produced by our factory and Cryogenic Center of China Academy of Sciences, main machine is produced by China Academy of Sciences. It have abundant experience in Turbine theory's design and make, its product adopt patent construction combined moving pressure and static pressure, so its ability to resist the turbine's vortex is very strong, carrying capacity is big. It wines the advancement second and third Prize of Science and Technology by Academic of Sciences in 1995 and 1999.
Rectification Column
It adopt fin type heat exchange, made in aluminum, heighten heat exchange affection, depress the operating pressure, reduce the power consumption furthest, saving cost.
It is equipped with exclusive instrument control cabinet. The temperature, the flow rate, liquid level etc. can be displayed in the digital display instruments. The special technology shortens the starting time to only 6 hours. The oxygen capacity and purity fulfill the relative requirements.
Our 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, keep the ground
level is ok.3. Adopting liquid oxygen pump inner-compress technology, we can produce high-quality medical oxygen with purity
range in 99.6-99.9%. The high quality oxygen products comply with the medical oxygen standard, widely used in medical and industrial area.4. Small volume, covers an area of less.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 oxygen requirements in time in different areas.9. It only takes about 15-20 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 5ºC~200ºC. 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.

All equipment are packed as required as general transportation standard.
