Refrigerent approx. +45 deg.F dewpoint, Dessicant approx. -100 deg.F (dewpoints listed are pressure dewpoint).
So you see, it's not just a simple answer for your question.
For a standard on Instrument Air see the following site:
www.isa.org
Find the following standard, ANSI/ISA 7.0.01 1996, "Quality Standard for Instrument Air"
This will allow you to determine what type of dryer you need, but why design one yourself, when you can buy one off the shelf.
Hope this helps.

1) Do we use multiple beds in the same dryer vessel or single beds are sufficient.
2) What type of support shoud I select for my packed beds- I will also need to re-generate it.
I just need general information regarding hte design. I f I am unable to complete calculations on my own, I will surely come back to you guys.
Thanks...

Dryer manufacturers may not be quick to give up bed support details.

ANSI/ISA-7.0.01-1996 (Quality Standard for Instrument Air)would be a good start.
Good luck

I would not expect you to specify bed support details to a dryer manufacturer. As TomOC mentioned, internal details are typically considered proprietary by dryer companies on standard air dryers (bottom line-you won't get a vessel fabrication drawing). Experienced dryer companies use various bed support methods.
Regeneration choices depend upon your circumstances and available utilities. Pressure swing (heatless) use ~15% of your dry air, but use no other utilities (~100 watts for the control panel). Various heated types use dry air, ambient air or recirculated air and can use electricity, steam or waste heat. Tradeoffs of capital,utilities and available purge gas will impact the decision.
CAGI (Compressed Air and Gas Institute) is the organization most dryer companies belong to...
