Air Separation products

Large air separation
Large-scale air separation equipment mainly includes output from 12000Nm³ / h to 60,000Nm³ / h. The large air separation equipment produced by DEAR is highly efficient and energy-saving, and can use multiple boiling points of oxygen and nitrogen for partial and multiple evaporation.
  • Energy efficient
  • Rigorous craftsmanship
  • Convenient operation
  • Smart and simple
Small air separation
Low pressure process is used to extract pure oxygen and pure nitrogen from the air by deep freezing and rectification. According to the different boiling points of liquid oxygen and liquid nitrogen, secondary rectification is performed in the fractionation tower to obtain 99.6% purity oxygen and Nitrogen with a purity of over 99.99%.
  • High Purity
  • Reasonable Configuration
  • Advanced Performance
  • Easy to Operate
High purity nitrogen air separation
Pure nitrogen and high-purity nitrogen equipment is one of our main products, and most of them adopt single (double) tower forward flow and return flow expansion process. The output nitrogen product pressure is high and the purity is not affected, and the one-time investment in the complete set of equipment is small.
  • Economic
  • Energy Saving
  • Safety
  • Reliable
Liquefaction air separation
Liquefaction equipment is divided into two processes of medium pressure and low pressure. The low-pressure process is generally suitable for small-scale liquefaction plants with a capacity of less than 1000m3 / h (LN2); while the medium-pressure process is suitable for medium-scale and above-scale liquefaction units with an output of more than 1000m3 / h (LN2).
  • Small Footprint
  • Low Energy Consumption
  • High Performance
  • Works Well
Complete air separation
The complete set of air separation equipment uses molecular sieve purification and pressurized turboexpander to supplement the equipment with cold capacity, full low-pressure process, high purification rate and strong adaptability.
  • Safety
  • Reliable
  • Reasonable
  • Economic
Bioenergy products
After several years of continuous exploration and innovation, the company's research and development of bioenergy equipment has stable performance and extremely low failure rate, which has been well received by customers at home and abroad.
  • Low Failure Rate
  • Stable Performance
  • Efficient
  • Environmental Protection
