The NDC CO2-free air dryer purifies your compressed air network to provide a continuous supply of clean, dry (-70°C PDP) and CO2-free (< 1ppm) air. It allows the replacement of bottles of nitrogen or oxygen at high pressure. 

The unit is very compact, save the space in the lab, silent, and easy to install. 

The NDC can inform you when the service is due via the display screen. 


Advantages product


- The use of air without CO2 reduces significantly noise from background for techniques such as FT-IR
- Protects sensitive optics and air bearings from moisture
- Tested and approved by most TOC and FT-IR manufacturers 


By producing clean, dry air from an existing compressed air system, you save money compared to using bottles.


The use of treated compressed air provides good instrument air quality, eliminating the need to change laboratory high pressure bottles. 


 Air quality obtained: - Water Dew Point less than -70°C (-100°F) - CO2 < 1 ppm - Particles < 1 μ
 Compact, lightweight design
 Patented PSA Technology: - Operation and regeneration fully automatic - Complete repressurization which means that there is no pressure fluctuation
 Quiet operation: The new exhaust silencers significantly reduce the sound level of the dryer (< 60dB (A)).
 Easy maintenance: Single cartridge containing filtration and dessicant which can be easily exchanged without the need for special tools - Less than 15 minutes
