safe and economic work with low pressure
no delay in operation while the instrument is being purged

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.

Compressed air supply

All Purge-Gas Generators are available with a external low noise and oil-less compressor for permanent use (<55 dba).

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 standards: 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.

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. Therefore dangerous and expensive gas cylinders are eliminated from the laboratory.
