There was a service bulletin put out by Carrier to perform this upgrade. I have been retired for a few years and unfortunately I do not have access to it....so I have to rely on memory. The internal...

I have found that you don't really need a spacer (which acts as a replacement for the impeller) to measure the thrust. I simply take a couple of feeler guages and insert one between the slinger and...

Pick out your favorite Wiley X frame and have your optometrist replace the lenses with your new prescription lenses. The frames are all ANSI rated. You then have a set of great safety glasses that...

Come to Florida, I got lots of beer here

I am the responsible mechanic for the 3 Multistack chillers that NYRB talks about. I started all three of them and have spent a great deal of time from my home tweaking the one oversized chiller. ...

Multistacks are able to run with condenser water temps a minimum of 12F above leaving chilled temps. In fact they provide an algorithm in the Flex Sys controller that will continually lower the tower...

Got this info directly from the Copeland (Bitzer) installation manual. I agree a phase meter would be ideal, but circumstances don't always work that way.

Install a pressure guage on the suction service valve to read compressor pressure. Close the service valve and run for approx. 5 seconds. The pressure should drop rapidly if it is rotating properly.

I have a 19XR lid2 for sale recently removed on a retrofit job.
The module part number is 19XR04005001. Make a fair offer and its yours.

Keep in mind all the negative comments about Multistack deal with their plate heat exchanger models. When you compare the Smardt to Multistack flooded chillers, the comparison is very close. I prefer...

I'd love a copy, thanks so very much.

I just replaced the gasket directly under the motor (motor temp sensor)and it was a flat rubber style gasket. Suspect the one I changed and yours are the same part no.

Project looks great. I would certainly like a copy of your powerpoint. What a great project to get involved with. You have some great salesmen to be able to land a project like this.

Sorry I can't supply a bulletin with Carrier letterhead. I worked for Carrier factory service for 10 years. In that time most of my experience was on 19DA to 19DR chillers. Obviously all low...

Yes I know, but my problem is not. I took the proactive approach and searched for threads that may contain the info I was looking for. Do you suggest starting a new thread and rehashing old info. At...

Customer calls us in to give competitive quote on replacing micro on 19xr chiller. Carrier has recommended replacement and already submitted their price. All maintenance is done in house so I suspect...

My chillers are built up with remote evap (6 floors up) and are not packaged units. They are used for process (they condense Hydrofluoric acid, nasty s$it). They are 1970 vintage. The evaps have...

Carrier manufactured this series of chiller with at least 2 seal configurations that I am aware of. The earlier version had NO "O" ring between the shaft and contact ring. Carrier instructions...

I believe it could be used to provide a constant delta T across chiller barrel, regardless ol load by varying the flow. There would be limits based on minimum and maximum allowable flow thru the...

It was rebuilt, with eddy current testing, both by York. York gave a 90 day warranty knowing the chiller hardly runs and this satisfied the customer. As you can see its been running for 7 years now...

I service a refrigeration unit in a plant that makes HF acid. You absolutely do not want to come into contact with that stuff, If I could show you video of an HF acid burn, you would run, not walk...

Could be a bad coil on the oil heater contactor dragging down the power and not letting the display fire up. By unplugging the I/O board you removed the power drain and up came the display. Something...

Need to have the end of the tube faced flush with the tube sheet so that the shoulder of the plug seats properly. Have used both and prefer the two piece.

Try Micro Control Systems in Ft. Myers Florida. They can provide a controller to replace the UCP2.

We have just installed a Multistack 180 ton flooded chiller. Very good build quality with isolation valves on every control for serviceability. Nice sight glass on condenser and evap so you can see...

Very high maintenance chiller. Great if you have a need for the waste heat such as domestic hot water, otherwise you are rejecting the heat to the tower.

Tonnage ratings are somewhat inflated. A...

I would say that you need to pull the top off, while its running of course, no oil pressure when its off, and stick your head in there real close to read the oil pressure guage. I think its located...

Schedule 10 stainless, I got approval to use from Trane on an air cooled remote evaporator installation. Project did not happen. the pipe was going to be welded and cleaned as required. The weight is...

Smardt advertises on their internet site for training at various times of the year. MY company has attempted to send multiple employees to the training, (since we now have some of these chillers...

There is a difference between both your chillers, chilled water flows, condition of...

Multistack has just announced a 600 ton flooded chiller using 4 turbocor compressors. Hvae downloaded the info and the chiller looks impressive, more industrial type cotrols. May be worth a look.

Try Blue Sky Technologies in Indiana............8122882033. They have helped me many times in the past dealing with other OEM's. Ask for Randy or Jeff.

Good to hear from you BB. That chiller has not run very much, probably why you didn't notice it before. It is tied in with the casino loop. Their system is completely down right for major repairs and...

Chiller Model No. YCAS0200EC58XFA

Compressor No. DXS45LA58

This is the critical one presently.

Would you be kind enough to send me a copy of the slide valve bulletin. I have tried all my Canadian and American contacts with no success. York acknoledges the bulletin exists but gives the old run...

Has anyone seen or worked on this brand of chiller. I have gone to the Armstrong web site and it appears the equipment is made in the UK. The site says both air cooled and water cooled versions are...

Hi Abs

Would you be kind enough to email me the form, I tried getting it
from JCI directly, no luck. My email is Email Address Removed

best regards..........wayne

Thanks for the reply. I don't have a diagrahm in front of me but I thought the unload signel came directly from the compressor controller. This is a Microtech II retrofit.
