High Productivity Liquid Nitrogen Generating Equipment

KDN- Type cryogenic liquid nitrogen generating plant which produces liquid nitrogen with a more than 99.999% purity, is one of best selling mini liquid air separation plant.
The integrated design and manufacture optimizes the structure and performance of the whole equipment. It is equipped with an automatic control system, with a high degree of automation, one-key start and control, simple operation and easy to use. It is a very popular air separation plant in laboratories.

Air compressor
The inlet air will be compressed into the pressure as per process required.
It 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.
Pre-cooling unit
The outlet temperature of compressed air is around 40ºC which is too high for the down-stream molecular sieves high efficiency operation, in order to increase the performance of the molecular sieves, a pre-cooling unit is required.
Purifier
Remaining contaminants in the process air such as moisture, carbon dioxide, acetylene (and etc.) shall be removed before enters into the main heat exchanger, a molecular sieves system is adopted.

Turbine expander
Turbine expander also referred to as a turbo-expander, is a centrifugal or axial-flow turbine, through which a high-pressure gas is expanded to produce work. It's the one of core part of the whole plant.
Fractionating 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.
Liquid pump
Liquid pump is a kind of cryogenic liquid pump, by which the pressure of nitrogen can be increased to achieve the purpose of transporting liquid nitrogen as user required.

The main data of the KDN- type oxygen plant is as following:

(Differ from other standard product, the air separation plant is non-standard product, we design and manufacture each product according to the User's requirement and environmental situation, so every complete set air separation plant is unique.)

  1) One of most popular air separation plant in the market;
