Carlyle 06NW Terminal failure

[eric_galliano]

Has anyone ever experience a terminal breaking off of the main connections for a Carlyle 06NW compressor. It is fitted to a 30HC 080-375 Carrier chiller system. Wondering if this is a design flaw or just one of those things. Also would anyone happen to have a parts list and break down of the compressor? Cheers.

[Dallas Duster]

Just one of those things from what I have seen or heard.

[eric_galliano]

How about having to change filters very often on the system. Seem to go through a set of filters once a month. System has never been opened except for filter swaps.

[Dallas Duster]

When you mean set are you talking external and internal? Does the compressors cycle slot? How's about a full model number.

Carrier 30 HXC 080-375 with the Carlyle comps. We keep having to change the internal filters. System was installed last year and they have been nothing short of a nightmare. No tech. service from installer. We are off the W. coast of Africa and supplier is in UK. Took the money and ran once job was completed.

I would check to see if the material stopping up the filter in metallic or something else. It`s probabnly a French made chiller and I would assume that their manufacturing processes are pretty clean. You might want to take an oil sample and have it analyzed.

[eric_galliano]

I'm going to pull the oil out of one of them tomorrow. Found out earlier today that we recieved more oil. As you suggested I will also send in an oil sample to find out what is breaking down. At this point I'm thinking C4 to take care of the problem. Do you know where I can come across a set of schmatics / enginnering drawings for the compressor broken down? Tried getting in touch with Carrier in the UK and US and no response.

It sounds like you have a contaminated oil system i have chillers running for nearly 5 years without any oil filter changes.
As for Carrier UK their service department will send a tech if you need one you can either ring 44-2088147600 and ask for Phil Treacher he is technical support in service or email phil.treacher@carrier.utc.com.
Change all of the oil and be prepared to do a couple of oil changes.
Send your oil sample off for analysis to find out whats in the sample then lets see what comes back in the report.

Tell him Gibbo asked you to contact him.

Exactly where off the west coast of Africa are you ?

Gibbo,

Thanks for the information. I'll give them a call in the morning. As far as getting a service tech. It is cheaper to swap the compressors with new ones once they fail. Currently offshore Congo W. Africa. Trying to prevent that as much as possible but, always a option.

[Gibbo]

I seem to remember Texaco Angola on their rig used the same logic for looking after their chillers. Their spares for 2 chillers was more than we held in the entire UK for the same chiller.
I'm sure a Carrier tech is cheaper than a 06N Compresser but thats for you to decide.

I have never heard of a 06N that needed that many oil filter changes anywhere.
What alarms are you getting ?

Gibbo

[turbomaster]

I have a copy of the 06N parts breakdown manual at work, I will forward it to you tomorrow.

[eric_galliano]

I'm getting pre start oil pressure failures, Low oil pressure failure, and max oul pressure difference. Not necessarily in that order or at the same time. I know your thinking that our attitude to the maint. of the equipment may be a little strange. Thing is if a piece of equipment is running and you can keep it running managment won't spend the money on a service tech. to come out and have a look at it. Also the attitude is if we can 't fix it then why do they have us here. We have been waiting on spare parts for the chillers since install over a year ago. I can get a compressor faster than a service tech or spare parts to maintain the system. All I can do is the best I can with what I have. Just for an idea after all the visa's, shot's, airline tickets, accomadations, and unforseeables. We would probally be looking at over 10K pounds before the day rate to get somone here.
Thanks for the advice. Cheers

[eric_galliano]

Turbo Master, Thanks. Will be waiting for it.

Phil has your email and will sort out what you have asked for.
You guys have a hard enough job on the rigs without worrying about a brand new piece of kit falling over every 5 minutes.
Is this doing the accomadation and offices onboard
Once you have the critical spares onboard life should become a bit easier.
Who was the supplier/Installer ?
Is this a oil rig or drillship.
The reason i mentioned sending a tech is he can give some product training and make sure your more happy and familar with this type of control and chiller.
Would be interested to know who commissioned it or was it just switched on and hoped for the best.
Make sure the oil is SW220.

All the best

Gibbo,

We have three set of chiller being used for the accomadations and quarters. Also installed at the same time were 2 walk in freezers and 1 walk in refridgerator for the Galley. A couple of weeks into the job we had to let go one of the installers due to multiple safety viloations which left one tach. on his own. We tried to help out as much as possible. Unfortunatly we do have jobs and were not as helpful as the tech thought we should of been. The company was out of Aberdeen and I would rather not name them out right. We are having what we think should be a warrenty issue with one of the compressors at the moment. When the units were commiisioned I believe it was a rush job to get off the rig. We also look for training to get some of the guys sent to and ended up finding a place in Orlando Florida. The request seems to have gone quiet since. If you would like more details about the units and installiation send me an email. I would rather not post bad feelings about a company on a blog.

Thanks

turbo master:
would have a copy to a server, send me a mail rogercastillo_1@yahoo.com.mx

thanks

Eric.

I understand why you don't want to name the company i have no problem with that. Regarding warranty i do feel you need to get this all done, have chillers been running for under 12 months with these problems and are they on all machines or just one. ?

[eric_galliano]

Gibbo,

One compressor came up with a Loss of Phase fault. This turned out to be a broken terminal stud ontop of the compressor. All of them are having the oil filter / oil problems. One we are looking for warrenty on is the one with the broken terminal or the parts to fix it would be nice.

Cheers.

If the metallic debris is ferrous, it could be coming from the discharge check valve. The older versions or the 06N compressors had issues with ovaling of the discharge check bore. As the bore became worn, the wobble and corresponding rattle became worse. In addition, metallic debris would be deposited into the separator where it would eventually be picked up and deposited into the oil filters. So why doesn't the external filter plug up first if it is upstream of the internal filter you may be wondering. The answer is because the internal oil filter has less surface area. In fact, both filters filter to the same micron size.

Ferrous debris can also be coming from the barrels themselves. Check the pressure on the CHW and CDW loops. If they run higher than suction or discharge pressures, a leak in a tube and/or tube sheet will result in water infiltration resulting in the internal corrosion of the barrel. The refrigerant scours the rust from the walls in the form of a fine powder which will eventually end up in the filters.

In addition to the oil sample analysis, you should also get the internal oil filter analyzed if possible.

Sorry fellas, didn't get a chance to send the file yet. If I don't
get to it tomm it will be Monday.

Turbomaster, please kindly email me 06N manual too. Thanks

[turbomaster]

Everyone who asked, check your mail.

Huh no comprehende amigo.

[turbomaster]

It's commonly available to whoever wants it. There are also several
other guides available, though they cost a few dollars each.

[eric_galliano]

Thank you very much.
