CO2 REMOVAL AIR DRYER NDC SERIES 

CALIBRATED GAS

The CO2 adsorption dryers purifier compressed air to deliver a conti- nuous supply of clean, dry (-70 øC pdp) and CO2 free (<1 ppm) purge gas. CO2 adsorption dryers replace high pressure oxygen or nitrogen gas cylinders and are ideal for numerous applications including FT-IR (Fourier transform infrared) purge, TOC purge, NMR, GC flame gas and laser purging. The dryer design has been developed with the laboratory environment in mind ? the unit can easily be wall mounted to save valuable bench space. Using proven pressure swing adsorption (PSA) technology, the units feature automatic regeneration and integral pre and post filtration providing totally clean, dry air with a CO2 level of <1ppm.

F-DGS products are designed and manufactured within an ISO9001 quality system and are CE marked.  

The F-DGS CO2 removal dryer uses the pressure swing adsorption principle of drying compressed air, utilising two identical columns each containing a hygroscopic  desiccant bed. Wet air from the compressor after-cooler enters the dryer through a shuttle valve (a) and is directed into one of the desiccant   columns. Each column contains a unique (and patented) desiccant cartridge which  incorporates inlet and outlet filtration. Bulk liquids (water) and particles are removed by the filtration/  separation stage (b) which is located on the inlet to the cartridge.   Water is retained in a “quiet zone” until the column is regenerated (when it will be vented to  atmosphere as the column is depressurised). 

Following the filtration stage, air passes through the desiccant bed (c) where any     remaining moisture is adsorbed. After drying, the air passes through a particle filter (d), which retains any remaining desiccant particles that may have been  carried through the system (<1 micron / ISO 8573.1 class 2 for dust).  Simultaneously, a small amount of dry air is counter-flowed down through the other   cartridge and exhausted to atmosphere, removing the moisture and thus regenerating the      desiccant. The dryer is controlled by a PLC which periodically switches the      solenoid valves when the compressor is  running, reversing the  function of each column  and therefore ensuring the continuous supply of dry air.
