Anyone have any teardown/overhaul literature they would like to share. Thanks

I have a 30 ton CGAF with a restricted braze plate and frame heat exchanger. I was planning on circulating RYDLYME through it for a couple hours to try and clear it, anyone have any luck with...

I sat through a presentation recently by a DuPont rep, and he also said all elastomeric seals should be replaced as ICEMEISTER stated. He also recommended adding 10% POE oil to the existing mineral...

Usually means you've been slugging liquid

by hydro testing could they be refering to a test procedure where a coil is put under nitrogen pressure and then submerged in water to see if it bubbles, indicating a leak......just a thought?

I had a similar problem with cvhe, after speaking with Cutler Hmmer and trying to just replace the power supply, we ended up having to replace the entire soft starter. There is also a fan kit...

Why would you need it in writing? Proper greasing of the motor will not harm it. By the serial number those units appear to have been manufactured in 2004, they deserve a good greasing by now!

I agree P-66 all the way.

I have a customer who put it in a CVHE. We did not reccommend them adding it, but they were givin the product free to try which is very expensive. They had a third party monitor the chiller...

I like to put isolation valves in to make changing driers and cores easier and faster in the future

I have installed these on many chillers. I have even rigged up a portable version that I can hook-up to any chiller for leak testing purposes. They have an adjustable setpoint for vessel pressure. ...

Just wondering if anyone could provide me with any information on a Carrier coil M/N 28G13-288 S/N 5-25-70, I am looking for CFM, GPM, number of rows and fins per inch. I am trying to save a trip to...

Does anyone know of a formula for calculating belt size? I know the span center to center and both sheave diameters. I have always used a peice of string to measure total distance and it gets me in...

on one of the first tube cleaning jobs I did, I valved off condenser, hooked up a hose to drain water and left to go work on another chiller. I returned about an hour later and saw no more water...

This chiller did not have any cond cleaning performed on it since feb of this year. I was also instructed by our factory chiller guru(JT) to add a lengthy disclaimer at the bottom of my job report...

I was on-site today to witness the addition of the additive to the chiller, a 1998 CVHE450, never has been overhauled, never a purge rate, purs like kitten 24/7, shutdown 3 days a year for annual...

We do not have an all inclusive contract with them, just PM and we bill all repairs. They are a very large well known pharmacutical manufacture with about 15 large tonnage centrifrigals on-site. My...

I have a customer who is going to be putting an oil additive into his Trane CVHF called permafrost. We, with factory input, have advised against it but the customer insists claiming an increased...

Plenty of work for us in central NY, our equipment sales are at an all time high this year, I have done more new equipment start-ups this year than in my previous 11 years. We are however seeing a...

The gun overall is 46.5 inches long, the barrells are 30 inches long from the breach to the end. I have no plans on firing it, I would like to take it to gunsmith to see about restoration. I am...

just wondering if there are any firearm buffs on the site. I am not, but am looking for some info on an old shotgun that someone has given to me. It is a side by side double barrell shotgun, 8...

I really wish I could change my user name. I don't know if I can. The name started out as a joke with the person who introduced me to this site. I honestly didn't think I would enjoy this site as...

In my opinion those low ambient kits suck, I can't even tell you how many of them I have had to replace this past winter. I prefer to use a Johnson P66. Just make sure to have a ball bearing fan...

Its a single stage, not quite sure of the tonnage, but it is a full working unit with ucp2. Thats the only absorber they have, but they do have some burners from the direct fired units. Dave said...

Dave taught the class, absorbtion essentials, and it focused mainly on the cycle of the single stage unit. Its really great to have a real working unit to learn from in the lab. Steve teaches the 2...

I just got back from a week long training class/lab about absorbtion chillers. I always stayed away from them in the past due to lack of training, but now I can't wait to get my hands on one. I...

TRANE makes an intelipak unit that gets modified in one of its Michigan offices that is a hot/cold deck set-up. The six we installed had dx cooling and on board, gas fired, boilers for hot water...

I had the same problem with a CVHE of the same age. Cutler Hammer told me that they had experienced some internal component failure inside their solid state modules. I replaced the module and...

I actually heard that the hardness of the ceramic balls were causing the races to wear, I may be wrong but I remember hearing something like that

Why would you want to go cheap on something that you wear every work day or maybe more? I have had Carolina Logger style boots for the past 10 years. They cost about 150-200 on average and last...

Just in case anyone was wondering, I did leave the unit the unit off with the gas valve locked out, and provided plenty of documentation to show that a leaking heat exchangeris present. I have never...

Just wondering if anyone has ever tried anything to temporarilly patch any small cracks/leaks in a gas heat exchanger. I have to replace one and have to wait about 2weeks for the new one to arrive. ...

I do some work on a true geo system that sound similar to yours with Florida heat pumps. Loop temp is around 32 in winter(ny state-upstate). We have had nothing but problems with them, manufactuer...

Why does everyone always assume that it is Tranes responsibility to solve every problem you may encounter on a troubleshooting job. Trane offers tons of literature and training to any one who is...

You can absolutely retrofit TRANE ch530 controls on any chiller. We have done several York chillers that had the Optiview panels with great results. Customer says chillers run better than ever.

killer dave, you sound frustrated that Trane was not able to solve your problem for you. I don't understand why people assume their is a Trane technician waiting for the phone to ring to help solve...

first of all lets start with some specifics on these chillers, mod # and ser # will help. Their are different procedures for all types of chillers. Air Cooled? Water Cooled?

WOW, first I ever heard of that! American Standard is the parent company of Trane. My paycheck says American Standard not Home Depot, but who knows?

I heard a rumor, and I pray its just a rumor, that Honeywell is trying to buyout Trane or American Standard, or something to that effect. I dont really put a lot of faith in the source, but just...

I work for a non-union TRANE office, and we do not have to buy anything. its plain and simple if you dont have the proper tools/safety equipment you are only taking risks on completing a job...

Its funny how the logo on my shirt may be different, but that may be the only thing!

maxster,
I work for the Syracuse Trane office. Hows things out in Albany?

I was on a job recently in northern NY, where the code enforcement guy told me that all links need to be changed every 4 years. Anyone else ever heard of this?

Make sure the test terminals are not rusty or corroded, if they are, jump across the terminals on back of the LTB, look for a blinking light on the UCM or RTRM board to be sure you are in test mode,...

In this case we usually have a qualified contractor come in and water blast the tubes, may want to eddy current test afterwards.

Is this an upgrade for Techview or a new version on a laptop where you never tried your key before. I had the same problem on a new laptop, turns out you need an additional program to use your...

I believe in jan of 2006 TRANE units will be available

I've done a few of these, the hardest thing is the rigging. The coil fins are razor sharp. The last one we did was only a 30 ton condensing unit and two of us did it in less than a day including...
