CARACTERISTIQUES & AVANTAGES - eliminates dangerous and expensive gas cylinders! |
Generating purge gas out of compressed air :
The new Purge-Gas Generators of the PG series are produced specially for the use with FT-IR Spectrometers to provide a purified purge gas and air bearing gas from compressed air.
The generator is delivered ready to use with coalescing
prefilters and automatic drains.
First oil-, water- and dust particles are removed from compressed air. CO2
removal is achieved by pressure swing adsoption (PSA) technology to reduce the
concentration of these compounds to CO2 < 1 ppm, H2O
< 1 ppm.
The molecular sieve is regenerated automatically by removing CO2 and H2O.
The process is being repeated continuously
in time and nearly maintenance-free.
To protect the whole system it is recommended to change once per year the
prefilter.
All systems are designed to operate continuously 24 hours/day, 7 days/week.
| Benefits : Using a Purge-Gas Generator of the PG series the FT-IR chamber will be removed much quicker from CO2 and water than using nitrogen. The user gets clearer backgrounds in a shorter period of time. The
small and space saving systems use your in house compressed air supply.

For units with built-in compressor please ask separately for dimensions,
weight and power consumption.
Max. flowrates higher than 85 Nl/min. are also available.
Max. air inlet temperature + 30°C. Air should be prefiltered and oil free.
To guarantee a longlasting maintenance-free use please use air with the
following standard :
ISO 8573.1, class 1.2.1.
Oilcontent < 0,01 mg/m3, water content < - 40°C dew point,
particles < 0,1 µm.
In case of dirty compressed air with maybe high rate of oil and water special coalscing-filters can be delivered.
