(U)HP Ultra High Purity Nitrogen Generators without compressor

(U)HP Series - Pioneering Pure Nitrogen Solutions for High-End Applications

Pure and precise - engineered for your analytics

  • Designed for labs, delivering up to 2 l/min nitrogen flow
  • Utilizes advanced PSA technology, achieving 99.9995% nitrogen purity
  • Integrated two-stage coalescence, particle filtering, and an activated carbon filter for superior purity
  • Optional feature: hydrocarbon removal to less than 0.05 ppm

You do not have a central compressed air supply in your laboratory?

Our model range also includes ultra high purity Nitrogen Generators with integrated quiet compressor (U)HP1A and (U)HP2A.


A hydrocarbon separator improves the gas quality considerably. This is very important e.g. for GC analysis. The separator ensures high-purity output gas (99.9999 % or 6.0 degrees) with a residual moisture content of 0.05 ppm and thus ensures reliable analysis.

Separators are an essential part of GC analysis, as impurities in gases can significantly affect the quality of the results. Hydrocarbons can cause problems such as background noise, altered peak shapes, false positive results or poorer consumption efficiency.

With our optional hydrocarbon separator, you can actively counteract this.



Nitrogen Generators with PSA technology for your analytical applications

With the (U)HP1 and (U)HP2 versions, Dürr Technik is expanding its range of Nitrogen Generators for analytical applications that require ultra-high purity gas.

The models are ideal for use in laboratories that already have a central compressed air supply or where a source of clean high-pressure air is available at the point of use (e.g. a Dürr Technik compressor station).

Due to their compact dimensions, Chromalytic Nitrogen Generators can be installed under the workbench to save space.

PSA technology is the ideal method for high purity levels and is used in our (U)HP1 and (U)HP2 models.

Efficient nitrogen separation provides reduced total air demand while ensuring the production of high purity nitrogen. Pressure swing adsorption (PSA) separates nitrogen molecules from oxygen molecules by adsorbing oxygen from the compressed air stream.

Lower real operating costs and a reduced carbon footprint make Chromalytic nitrogen generators the ideal solution for your laboratory.
