would you offer a summer only position? Say, from now through September?

In a sea of technicians (and technician accessories, ie: managers and dispatchers and what not), I think Mongo and me has the right attitude. Can't take it all so seriously

has the frequency/hz of the incoming power been checked?

I carry the Fluke 87V.
My apprentice carries the fieldpiece stuff and is constantly confused by the voltage readings. IE...whether it's volts, millivolts, etc. Of course that's just him being...

go into your local a/c/r parts house. many digital stats out there allow for remote/multiple room sensors. they are readily available

we do alot of marine refrigeration on these large cargo container ships and military vessels as well. If you thought to replace a valve that was leaking packing, these folks on the ship would think...

sorry 6.5 ton

direct drive fan

could crap on the fan blade cause such an air flow loss to have the effect I'm having?

Got this gas pack unit, approx 15 years old

try changing out the evaps in a walk in cooler AND freezer all in the same 25 hour continuous shift with no backup. last thing to do is hook up defrost timer and assure it's working. good luck on...

while the circuit is still in a vacuum, you can just "pull" in new oil at the compressor suction port with your refrigerant hose. I recommend devising a way to prevent the addition of air during...

so when a boiler is off do you close off the flue? I did notice that on this first boiler (of three) that I'm retrofitting that the blower wheel is being turned by the draft pulling through the...

what is this guillotine on the exhaust vent?

old stuff.

just curious if you know the tonnage off-hand. My guess would be 6 ton, but don't know for sure. also, do you know the year of mfg?

come out with male flares and install a cap on them. you need to put a nitro holding charge and purge on the lines anyhow, so this will be a perfect spot to facilitate that. then later, you can...

This is Jonathan from down at Emcor-Lake Forest a couple years ago. How are ya man? What are you up to these days?

any chance that your control signal is too strong and burning out the actuator?

call a pump shop. They'll readily calculate it for you if you have piping dimensions and lengths

there is only one option: call a mechanical contractor or engineering firm that you are comfortable with and have them submit ideas to you based on your situation. There are MANY ways to solve...

I've installed a fair amount of both.

It's true that vic is less labor intensive and faster, and anyone as smart as a monkey can put it in.

The welding takes longer and you need an...

your most accurate will be your DP across the pump, then determine the flow from the pump curve.

that chart on the triple duty valve is just a starting point, a rough idea at best

here's the bottom line:

the system was designed and installed with insulation, and now it's damaged to the point of being exposed to ambient conditions. you've lost whatever efficiency was gained...

unfortunately, all the contractors ahead of you went the 'lazy' route as well. now you have to determine which of the control contactors has a bad coil or where a control wire is bad.

I had a...

they lay off the journeymen and experienced folks and hang onto the cheaper apprentices and mechanics that can knock out all the cheap maintenance stuff and struggle through service calls. then when...

the only person that can give a 'detailed' description of the maintenance requirements of each piece of equipment you have is a hvac professional on site. contact a few different companies and have...

yeah I've got this stuff that's got orange flux on the outside of it. it seems to stick to anything. I love it. I always cap it with 25% silfoss rod, but that's probably not necessary if you are...

you can silver braze on a steel fitting. if you can go brass or copper to steel with it, you can go steel to steel, seems to me.

any chance you could put in two flow switches and adjust the springs to close at different flows?

I wonder if one of these 'lithium ion' battery makers would be interested in your lot. might be worth their while to separate the crap out

what he's trying to say is that if he can't put a tap in the small line he's working in, he'll have to recover the 5000# (seems like a lot to me...must be a very large chiller) of gas

all you need...

I work for a really new contractor and we do a lot of factory startup for a few different distributors. I've been just making my own excel forms due to the fact that I hate having papers everywhere....

fan spinning in the correct direction? the motor will state on the name plate what the correct amperage is. you should be at or below this number, but not drastically below it. I'll be happy if...

multiply the diameter by 3.14, which is commonly referred to as pi

so if you're diameter is 2.6 inches, the formula will be

2.6 x 3.14 = 8.164

I wonder if there are attorney's who specialize in mechanical systems

what would make the parts more expensive? and why would a mfg of these highly sensitive machines require the more expensive parts?

I'm guessing the more expensive compressors are built with much...

I think giving hints and help to non-technician types is very dangerous. he can be horribly burned by refrigerant release. He can be shocked badly from fooling with controls. I think it's bad...

so bringing it up to 50% speed in 15-30 seconds didn't prove to be a lubrication issue?

I've always wondered about why we can't use variable speed for capacity control on a recip and the answer's always been lubrication. I wonder if you had an auxiliary oil pump to pressurize the oil...

is the grease your using rated for that low temperature?

really, if you're looking for anything more than a temporary 'rustic' fix, you need to employ a mechanical contractor/engineer if you have the slightest hope of your system having true functionality...

costco has great looking propane fueled heat lamps that work great. restaurant style

on both machines, the branch tee at the top of the purge barrel was just hand tight. I'm sure that was a good leaker. When they return in two weeks, I'll be hooking up the heater and doing a proper...

the reefer engineer pointed to a small fitting on the top of the machine that is all rusted. located in the suction 90. I wish I would have taken a picture. anyhow, once I get it in a positive...
