2005 York Chillers - Tube Counts

[MasonIndustries]

Hello Everyone,

I am looking at purchasing a couple of 05' vintage 3,000 ton York chillers (mod# YDYFYBJ3-DCA) and according to the literature the tube counts are as follows:

Evaporator: 183 - 0.035" Enhanced Copper Tubes
Condenser: 262 - 0.035" CSL Enhanced Copper Tubes

I was looking at scrapping them as it can be very difficult to place an end user for chillers of this size especially when I haven't been able to secure documentation of service records. To my way of thinking these tube counts can't be correct. That is what I would normally find in 300 ton chiller. I am also surprised that chillers of this vintage would have 0.035" wall thickness. If anything I would have expected the tubes to have thinner walls than normal.

The operating weight of these things is 162,000 pounds a piece. Does anyone have any insight into this matter? I simply don't see any possible way that these tube counts could be correct.

Thanks for your help,
Joe

Those numbers are a designation of tube type. It's not the quantity. I don't know if I have any YD literature. I'll check in the morning.

By the way, you posted this in the wrong forum. Should be in the chiller open forum.

I haven't dug up any literature on the York YDs. Never saw one out on the West Coast. Anyway, tube wall thickness and material type can be ordered from the factory. Tubes could be ordered as copper or Cu-Ni. Wall thicknesses of .025", .028" or .035". I did look up the most recent YK parts and for the largest YK offered (as of 2010) had 1850 tubes in the evaporator, 2325 tubes in the condenser and 180 tubes in the sub-cooler for a total of 4355 tubes. Those shells are 14' long, so there is 60,970 feet of copper tube. We used to use approximately 1 lb./ft as a rule of thumb so in the largest YK shells you would have close to 60,000 lbs. of copper. Your mileage may vary.

on the Series A chiller, the YF evaporator has 2,004 tubes and the YB condenser has 2,496 with an additional 180 tubes in the subcooler and i see them as 18 feet long. the YF, with a 183 designation, is 0.035" wall and the YB, with a 262 designation, is also a 0.035" wall.....

with KY definition of 1 lb/ft, there is over 168,000 lbs of copper in 2 chillers! party is at your house!

Quick question ? How much do theses machines weigh, 84,000lbs each ,wow? That's just copper only.
