Depends on where you pulled from and the chiller design.
Not sure if the European numbers are the same as the US numbers, but the valve is a 022 11858 000 and the oring between the valve and the barrel is a 028 12961 001.
the US version comes with an...
New valve is needed. That is a straight thread valve with an oring. The nut tightens down the washer which seats the oring.
sounds like your Alerton BAS programmer needs to change the program. many programmers (mistakenly) believe that once they start something, it just starts immediately. they don't. there are time...
I don’t know about refrigeration systems humidity sensors, but if you want one for regular human humidity monitoring, they are expensive. You get what you pay for.
Most of the piping will likely be oversized which isn’t all bad on the liquid line (other than costing more money for more refrigerant) but could be bad on the suction side where the velocity may be...
"Downflow, Upflow, whatever it takes" - Mr. Mom
I have a cheap harbor freight one that use from time to time. Adding heat is usually the key. We have maxed out the 5 ton piston and it still didn’t work. Add heat, Stay out of the danger zone.
I would recommend sticking with the OEM on a military application machine. I work for JCI and I was told that if I visited the manufacturing site for those machines, I would have to have DOD...
I have never figured out how to clean the refrigerant side of the shells without making it worse. I just always added more filters in various places and added some clean up kits. Let the refrigerant...
with version 12 (Y.OPT.01.12.XXX), after the first 30 minutes has expired, the MINIMUM liquid refrigerant level in the condenser and the MAXIMUM liquid refrigerant level in the condenser are recorded...
I do t know what the code would say in this case, but the “code” that applies to your situation is what the governing body in your area SAYS is the code. They can pick which ever code they want to...
My biggest concern is the “middle ground” money during a failure. That money that is not as much as a chiller but not covered as a normal budget item. When this happens, the upper management think...
Yup. I try to do what is in the best “long term” interest of my customers but some don’t see it that way. So we will let them spend a bunch of money now and then a bunch of money later rather than...
We have already gone down that route. I would hope that the previous contractor also discussed that as well but I am not sure (there has been some personnel changes). We are on to Plan B. We have...
So, a customer who hasn’t any money (or isn’t getting any)….I should just let them flounder and I should try nothing? And “not supporting” doesn’t mean the same thing as “not producing”. We were able...
thanks! i looked up some generic sensors so i can probably have one made or find one but i was looking for the easy way out.
i don't have the sensor and it currently isn't failed...looking for spare parts for a state institution who refuses to put any money in the chiller for an upgrade or replacement. trying to save my...
anybody know what Trane is doing about the obsolete TDR00272 pressure transducer for CVHE/F with HI (UCP2) control panels? is there a service bulletin? WebCATS says obsolete November 2023 with no...
is there a reason you don't want to use the York ones? i believe another company makes them for York but to their specifications. i am sure other microchannels are done the same with other brands.
Thank you for setting me straight. You have a nice day.
that's 100% true. we have to be careful what we ask for AND realize what may happen if we don't ask for everything.
first off, i know very, very little about Daiken.
you seem pretty stuck on the "authorized", "factory", "approved" tech concept. i get it. if they have that moniker, they should be pretty good....
i only have experience with the York mag bearing chillers....so far, mine are working very well (i know some techs around here have had a hell of a time with theirs). as a whole, it is fairly new...
we have done it to ourselves. we asked for cheaper...and what do you know...they gave it to us. we placed our money in the stock market as a "be all, end all" and wanted greater returns....and they...
Not to belabor the oil issue, but you verified that you removed 100% of the existing oil charge and then added 100% of the nameplate oil charge? If you added more oil than you removed, then you have...
I also wouldn’t trust a wire nut. I use them for sure but if I was troubleshooting, I would replace them with insulated terminal connectors or twist the wires together without the nut (carefully...
Yes, the refrigerant could have bled through to the other refrigerant circuit….running this circuit and checking your pressures and temperatures should tell you if that has happened.
The...
there will be lots of parameters in there. what are you lacking clarity about?
Your sensors are greater than 13.9K (25F) difference. Assuming your sensors are accurate (and new doesn’t mean accurate) then you don’t have a sensor problem you have a systems problem…low...
i cant explain the missing page in your manual...i see a similar one in my 2020 manual...at least the first page anyway. the second page may have been from some other manual that may or may not have...

Most brands have a screw chiller that would fit your application pretty well. Centrifugal chillers can be designed to handle higher condenser water temperatures…85F entering condenser water...
Have you replaced the valance lately? What about an accurate suction temp sensor? You say that the superheat is -3…on the display or with your measurements? What is the discharge superheat?
it works out...0.00030 amps x 200 ohms = 0.06 volts....close to your 0.1 volts
so i got curious too. i found a 1 HP, 208VAC, single phase condenser fan motor (capacitor had been removed) in my...
Thank you for that thorough answer. I hope he hasn't been checking back daily for 8 years.
The York YMC2 chiller motor has a permanent magnet rotor. I think the Daiken/Turbocores do too, so, they can create very large currents when the move including high voltages. You need grounding wires...
Correct. It is very small of course. The voltage out of a regular DVM is about 3 VDC or less. It wouldn’t take much movement in the rotor to mess with it.
How does a non-magnetic rotor generate power in a winding?
It is normal to have changes. Your volt meter is inducing a very, very small amperage into the windings which creates a magnetic field which then gets changed as the rotor turns. The same goes for...
Just because the design says it will work doesn’t mean that the design will work….most of the time, that is true…but not always. I have a Trane that is used for building heat that run 14.5 psig 24/7...
it is not to be pressurized beyond 5 psig under any circumstances. the system is not supposed to be a sealed system. i see teflon tape on the pipe plug a lot and i remove it when i find it.
Some of my screwdrivers identify as chisels. Some of my Crecent wrenches also identify as hammers. Can’t seem to get every tool on the same page.
Your economizer line is hot because your compressor is hot.
Suction superheat of 44F is too high. I suspect your discharge pressure transducer is reading incorrectly or your condenser liquid line temperature sensor is reading incorrectly or both.
So, were the WIRES or TERMINALS hot or was the MOTOR WINDING TEMPERATURE SENSORS hot?
No. Is that Nylogs property?
There was a “clear coat” or something on lots of fittings in this chillers purge. A failed flare is obvious. I assume it’s Nylog or something similar. It looked more clear until I wrenched it off. I...
1/4" flare nut. previous contactor tried Nylog or something similar. you can see the worn out flare on the left side of the copper. new flare and all is good. let's try fixing things properly in the...
Fun product for Home Depot DIYers. I am not sure that I want a meter or sensor that uses the word “Volty” or “Tempy”. Makes it difficult for me to take it seriously.
