I bought a set of the exact same pipe clamps and the rubber boot opposite of the sensor boot on the liquid line clamp had broke, my fault. Don't be rough with these clamps because they are a little...

I have had the fortune of installing and providing service for Fujitsu, Mitsubishi, and Daikin. I work at a University so we get exposure to almost every brand stated in this thread. I have...

Hello everybody,

I am writing to see if anybody out there can help me find a compressor I/O board that needs replacing. These boards are no longer available through Trane so I am coming here to...

Love my veto. I'm sure it will last for several years to come.

I agree about the possible low charge at night with using a headmaster. The first method would be to calculate the proper charge and weigh in the proper charge. Sporlan has a great bulletin on this...

My question is I have recorded 2 compressors data for 8 hours. I now have the files and can watch
the time date stamped values throughout the 8 hours. My question is can I export this data into
an...

We have 2 Mcquay WMC chillers, I guess I should say Daikin now. From what a friend who has been with McQuay for 30 years says the name Mcquay will be completely removed from them. We also have 2...

Im just finishing up rebuilding a York YSC slide valve piston assembly along with replacing the pot for slide valve position. I will relay you any wiring diagrams that I have. Let me know if your...

I have a 4 story building that has a closed loop water system in which it is used to cool the shell and tube condensers on about 20 refrigeration walk-in condensers. The closed loop cooling tower and...

Sounds like your a pretty smart guy uhPrintUs.

This is not a small amount on moisture. Water in the the oil sight glass of a scroll 15 ton compressor is not a little water. I removed the main removable shell drier and got water drops coming out...

I do not believe this is true because there was more refrigerant pressure when I hooked on to the refrigerant service valves then there was water pressure going through the shell and tube condenser....

Arrived to a call today to find one of the circuits (two scroll compressors) with what looked like water in the sight glasses. This system utilizes a water cooled shell and tube condenser. I have...

Just used the new recovery machine. I was very impressed with the machine. I did however make a "subcooler" out of 1/4" copper that I put in a bucket of ice to increase the recovery time. I...

Boss just ordered this new recovery machine. I was wondering if anybody has used it yet. It is the Pro-set TR21 Revocery machine made by CPS. It claims to be almost twice as fast as the Appion G5....

Thanks Icemaster for the link to that. I could not find it earlier.

I was wondering if anybody can supply me with detailed instructions on how to fabricate a four piece fitting that fits over a 90 degree elbow. I do not want to use a 45 degree angle. I believe this...

GoColts,

If your taking this exam in the Sacramento local 447 then your 5th year teacher Ed Swisher is awesome. He will provide you with all the information you need to pass the test. I was in his...

I am writing you find out if a Hoshizaki "flaker" ice machine can be supplied with DI water. I found through the Hoshizaki website TIPS125 that RO water is not to be used. However does the same...

We have just installed a SMARDT chiller with dual turbocor compressors. The contol logic for the chiller is Kilteck. Our chiller is water cooled. It has been running for about 6 months with not one...

I was just looking at your install. You guys did a nice job! I was wondering how do you like your set of digital refrigeration gauges?

I am writing to find out if any of you guys have seen refrigeration condensing units with the copeland digital scrolls installed on them. I've started up a few AAON units with the copland digital...

I have been working in the HVACR field for about 13 years now. I started my career in residential air conditioning (for about 3 years). The company I worked for sold only Trane equipment. I think the...

Just wanted to throw in what I know about 407C. It is a blended refigerant, meaning if you get leaks in the system you need to recover the whole charge and repair the leak then add new refrigerant...

Has anybody had any experience with the oilless compressor made by Danfoss/Turbocor? I noticed that McQuay is using them on some of there new equipment. I hear that they are 20-25% more effiecent...

I have noticed that Danfoss has joined the Canadian Company TurboCor in the magnetic bearing, oilless turbocor compressor. This little centrifigul looks like the wave of the future. So many...
