I need a few suggestions on where to look for this AHU.  inlet water is 42 deg-F.

thanks,
 

RE: 15 ton 6 row chill water coil AHU

Beyond my typical design conditions, but wouldn't one of the standard AHU manufactuer's be able to pull this off:

McQuay, York, Trane?

Failing that a custom manufactuer:

Haakon, Engineered Air.

RE: 15 ton 6 row chill water coil AHU

it should be fairly straight forward, pretty easy with 6 rows and 42F

start by looking for a model with a 12 square foot coil section

here is the econo version http://www.trane.com/COMMERCIAL/DNA/View.aspx?i=1022

Take the "V" out of HVAC and you are left with a HAC(k) job.

RE: 15 ton 6 row chill water coil AHU

Why do you limit it to 6 rows?  If there is a concern for airside delta-P, there is also fin and tube spacing to play with. Depending on circuiting, you might not even need 6 rows.  I believe HeatCraft's coil program is downloadable for free, you could play with the different factors.
