One of our supervisors got in touch with a local York parts rep and got an answer.
York says "these seals are designed for some oil leakage"
Well H**L, we figured they'd say that.
It has the info you need to make the puller and overhaul the compressor.
Thanks for all the replies. This gives me something to go to the customer with.
I worked on open recips for years and those seals seldom dripped. When they went it was obvious. I thought...
Does anyone have info on the allowable shaft seal leakage (oil) on York open type centrifugal compressors. All I find in the manuals is that some leakage is normal and just discard the oil collected...
I am told service tool doesn't work with any version of Windows beyond Windows 98. I haven't tried it on ME or Xp so I don't know.
You also need the B&B converter to connect to the network.
Condensers are on a closed loop using a plate/frame heat xchngr. Water temp controlled by GBAS (70 - 80 deg.). Fan speed OK.
I actually watched the unit cycle several times on supply air temp and/or...
We don't have air or WS economizers and disabled MWU and NSB. Unit HI never indicates anything preventing compressor operation. Also, as I mentioned, the only way to get it to...
Most situations I have experienced with "too small" involved air leaks throughout the building which never let the compressor catch up. Quite often, where demo/remodeling work is done lines get cut...
I posted this in the Pro Forum also.
I wonder if any of you Trane experts have experienced this.
A multistory office bldg. (partially occupied) with VAVs and PIUs on SCWG intellipak...
Try this site for DowTherm products for chillers etc.
Check with Dwyer.
They have a good variety of flow and pressure controls.

Seems like I remember doing something like that with a small motor. With no load it slung the rotor apart. I have no idea what the RPM was but it was FAST!
BTUs/Hr = GPM x Delta T x 500
With DC you don't get the AC hummmmm.
Contactors are quieter.
When a large inductive load such as a motor hits the line it drags the voltage down considerably. This causes dimming of lights and a whole multitude of other problems.
Most utilities dictate the...
No, it's not backwards.
Think about it. Dewpoint is when liquid droplets start to form in the refrigerant vapor mixture. Part of the blend has a higher boiling point than the other at a given...
If you are checking superheat use the dewpoint.
If you are checking subcooling use bubblepoint.
OK, here's my story. Reading Shogun's experience reminded me of a simular situation.
A large chilled water air handler with a 4 row coil located in a student center at a local college just didn't...
I remember reading that silica was very hard to remove.
Found this in old RSES SAM manual.
Heavy acid concentrations require (3 gal. liquid scale remover to 10 gal. water).
Also, after initial...
I gave up on the batteries in the Robinair and installed a jack that I could plug a wall wart power supply into.
It served me well. it's somewhere in my basement now.
Thanks again for the...
Excellent information! Thanks.
I guess at some point we are going to have to trust all of this new fangled electronic stuff.
From what you are saying, I think I would go with the Yellow Jacket too....
Flotronic Monitor is available from your Carrier Distributor support guys. It's DOS based software that allows you to look at all of the temps, stages, and EXV positions while chiller is operating....
A compromise was the 3 pipe system where variable temperature hot water and chilled water were both supplied seperately and mixed with a valve at the coil to provide desired air temperature. The...
These are the older model Carrier Flotronic chillers.
30GB, 30GT etc.
the newer models require the use of Network Service Tool or ComfortView software (which gets into your pocketbook).
it really gives you a larger picture of what's going on during operation. Especially TXV position.
You will need the Telebye Model 65 (or equivilent)converter connected to J8 terminals 3 & 6. I...
