I have an interesting problem that perhaps someone can give an answer to.

A client asked if he could use a York packaged chiller
(it is the one with the Frick screw mounted ,
upside down above the chiller I think it is a tdsh 163
short 200 hp),
was used for ac water chilling but now he wants to chill
a salt brine solution to -40 degress F.
Now before the questions.....
panel and starter were changed to accomodate the low
operating conditions, oil cooler was enlarged for the
extra heat of rejection, and misc other minor changes
such as a slide valve modify, r-22 is the refrigerant
Load is approx Xx tons with a flow rate of 450 gpm
in at -39 F and out at -43 F PD not a problem..
The system will drain and flush the brine after
each daily usage to alleviate damage to the copper
chiller tubes.

The original capacity was about 200 tons so the 30 or so tons should not be a problem
I believe there should be ample surface in both the chiller and the condenser to do the new capacity.

NOW YOU CAN FIRE AWAY. ANY INDUSTRIAL YORK GUYS OUT THERE THAT HAVE USED THIS UNIT FOR REALLY LOW TEMP??

I really look forward to your comments, This seems to be an excellent one for you Iceman...
