AMMRL: Dry air supplies

Dear NMR Friends:





We are purchasing a new CP-MAS probe and need a source of dry
air.  Our house air (80-90 psi) is sometimes wet or oily and we
need to clean it up.  A company called Kaeser sells a Desiccant Dryer KADW-15 Wall Mount (15 SCFM,
up to 150 PSI, -40 C dew point) with two desiccant columns and filters
for about $1600.  We have a similar one for FTIR and it works
good (except for the occasional pressure release which one kind of
gets used to.)

I would be interested to know if there are any experiences out
there with this unit or with alternative solutions.  If there are
sufficient responses, I will share with the group.





Thanks in advance,


Frank
