Hey guys,
It has been some time since I have posted. I am hopeful you guys can provide real world experience with York equipment vs others.
Over the past couple of years we have noticed that York...

They have that for water/hydronic systems. Picture a pipe and another slightly smaller pipe within the larger pipe. The smaller pipe/slip can move but needs to be sealed. There are different methods...

Expansion joint. Depending on the model that plug would be the packing cylinder. We have 6 expansion joints to replace this summer on a university steam system. Ranging from 4” to 18”.

No, not common. Years ago I worked on an extremely old carrier split for a member of the DuPont family. I was told the condenser was one of the first systems ever produced and the condenser was...

Have you chemically cleaned the HX? Talk to your chemical treatment company and inform them what materials the chemical will come in contact with and cook it out. We do this frequently up here since...

Success takes hard work no matter where you live. Headaches are everywhere. I think a difference you might find south is the pace. The North East is fast paced

Need all the info on combustion results. Is the Air damper automatically shift between different fuel sources? Digest gas contains approx 40% less btus compared to natural gas. So when you switch to...

Even though the piping is incorrect the fact each boiler has its own circ pump will guarantee the boiler has enough flow. Are the main loop pumps on a VFD? If so has anyone increased lowest speed...

Does it flame out on main flame trial for ignition? Or does it snuff itself when it's starts to stroke from low fire to high fire?
If it occurs after MFTI I would like to know your CO, CO2 and O2...

Tell them to install a 3 way valve so they can maintain the boilers with a minimum return temp of 150 and provide a blended supply to the building at 120. 150 could be too low if the burner sits in...

You do not require supply air per code. You do require exhaust. 75 cfm per toilet. Minimum. We always suggest electric baseboard heat or some type of heat for the winter due to cold toilet seats...

You need your low fire O2 around the same. When you start getting above the 9% range you getting these issues. We just did a startup on some Fulton boilers VMP 130 HP and they have linkage less...

Low fire O2 is way too high

what kind of companies do you guys work for?

I have buddies doing amonia, but their company goes through techs because of the stress. If you think a store with a system going down is bad try having Kraft foods production come to a hault and...

This is normal, is it a drop ceiling? If so install batts of insulation

All of us got certified today since we are working at a bottling plant, strange thing is that we never heard of it until going through this plant. After digging into it last week we realized its the...

Check the side of the boiler, it will tell you the design delta t

What is your combustion readings? What's your inlet gas pressure and manifold readings, do you have a barometric damper? The tubes will fail, only a matter of time. If you get a hairline crack it...

If you want to see if you have condensation issues just look for green streaks all ove the heat exchanger. To have 4 burner tubes severely cracked over 6 yrs is not bad at all. Just wear and tear.

What's the size of the boiler? Make and model. Old boilers used to have single blocking valve and now are required to have 2. Some applications will have a gas vent solenoid between the blocking...

From experience, sounds like its being over fired. We have a meat plant that we have 13 of their copper fin boilers and on average we replace 4 tubes per water heater. Unfortunately we have to over...

No danfoss

check valve is bad. Instaleld a 50 ton carrier and the new compressor did this. Carrier ate that one and replaced the compressor and paid for the crane and all!

Standard units up to 15 tons or so, our expierence, it is always the time delay

If he does have those readings I want to see it! What's is the highest subcooling youve ever seen? Not trying to hijack the thread.

youre saying 140 degrees super heat?
290 degrees sub cooling?
20 horse power?

43 degree SH is really warm, most compressor mfg would tell you thats too high. We have a Drake chiller running at 30 SH and manufacturer said if you get to 40 they would be concerned. The chiller...

Hey guys, just picked up a new account with a McQuay recip chiller. M# WHR060E-A S# 56F8127200.
Looking the manual and if anyone has and service bulletins or know of any issues?

Thanks guys

They use the tools because this helps reduce the skills required to service the equipment. Many techs out there are good enough with electrical but have a difficult time with the refrigerant side.
