To explain the glycol system for you a little, there are actually 2 loops in the system. 1 using ammonia, and 1 using glycol. The ammonia is not actually cooling the area where the coil is, it is only cooling the glycol. Once the glycol is cooled the glycol is then pumped to the coil at the area that is being cooled. The glycol supply gauge is actually the pump discharge pressure of the glycol that is being pumped to the coil. The return pressure gauge is the static head pressure of the glycol at the suction side of the pump. So you're actually looking at the pressure of the glycol not the ammonia. They are separated, so the pressure of the ammonia is not going to change the pressure of the glycol pump pressure like you'd think. You could evacuate the ammonia and have 0 psi and still pump the glycol and have pressure on those gauges. Hope this makes sense and helps you better understand your system. Keep it up man and you'll get it!
He probably does rounds and reads pressures and checks the liquid level's in the receiver and that's it. We have guy's like him where I work at and they are extremely dangerous. Seeing that their is no other video's on this system, or him making any actual repair's I am going to say I am 100% correct.
NorthernCaliWay; I just switched back to industrial refrigeration service from market service. The main difference is the size and demand of the systems, and that ammonia is actually a popular refrigerant in the industrial realm due to its higher capacity, cost, and environmentally friendly attributes. Markets are pretty typical, in that the compressor racks and local/stand alone units basically service cases and walk ins. You do have self contained units and ice machines to deal with, but those are significantly smaller in scale as opposed to industrial equipment, obviously. In industrial, you have much larger systems that accommodate a wide variety of processes, lots of cold storage but also lots of other production line equipment like spiral freezers, blast coolers, glycol/water chillers, liquid product chillers, among others. The labor involved in each sector of the refrigeration industry, whether it be markets or industrial, is kind of similar. Some markets, like Costco as an example, are pretty big for commercial and require a lot of work to diagnose issues and make major repairs. But, once you taste what it takes to maintain, service, and repair a large facility, the differences become quite clear. Some preventive maintenance tasks can take up to two days, using a big screw compressor as an example. For example, on one ammonia screw compressor, to do an oil filter change, suction strainer cleaning, liquid line strainer inspection, the job can be billed for 8 hours, sometimes (which should really be every time when dealing with ammonia) with two techs. That’s just for one compressor. Now throw in a motor replacement and alignment... That’s gonna take a lot of time to align and verify alignment after putting in a huge ass motor. An entire rack in a supermarket can get an oil change with filter replacements and liquid drier core replacements in roughly the same time (8 hours), depending on how the job is bid or how many racks you’re dealing with. What I like most about industrial, particularly with ammonia, is there is an understanding that many service orders and preventive maintenance tasks take much more time, and when dealing with something like ammonia, you can’t cut corners or you run the risk of getting yourself and others seriously hurt or killed. The culture in industrial tends to be much more detail oriented because there’s a lot more safety risk involved and waaaaay more money to be lost by losing hundreds of thousands, if not millions of dollars worth of product given the size of many of these industrial facilities. Both commercial and industrial are labor intensive, but when you have to change out a 700 pound screw compressor in an engine room that runs 50,000 lbs of ammonia, there’s no comparison to the labor. But, changing out a 50 horse power recip compressor in a market engine room can kick your ass, most definitely. Just depends on each job. Anyway, I love the bigger stuff. I think no matter what you’re working on, whether it’s commercial market or industrial, some jobs are easier than others, labor wise, regardless of what sector in this industry you’re dealing with. Refrigeration service is a crazy world.
NorthernCaliWay; Both industrial and market refrigeration service jobs are extremely demanding. When dealing with food product and processes, the customer will call any time day or night, and you have to show up. No real way around that, and you have to know what you’re signing up for. It can get brutal in both.
@@Griff1904; Awesome, man. Good luck on getting your certs! I’ve been pretty fortunate, considering I’m not yet certified. Honestly, your hands on experience is going to give you more knowledge than any cert can give you, but it’s a good stepping stone in understanding the basics of it all. Good luck, bro 🤙
I am in Chennai. l have experience in ammonia and freon refrigeration & air conditioning.20 years also Electrical, maintenance looking for job. Thank you.

Two years later, I’m seeing this and I’m starting orientation in a few days. I appreciate the video and the knowledge in it. ✊🏾
I got way better . I learned a lot working at these 2 plants
⚡👍⚡
Talkin till that red light turns on! 😂
Love the video bro
Are you a Pipefitter or a Refrigeration Mechanic?
Whats the actual name of your job title and what time of training/schooling/education do you need for it
I’ve been working in the Supermarket refrigeration sector but I’ve been thinking about going to ammonia industrial refrigeration
ITS COOL

@@seanmichael8202 great fucking info! Pretty spot on. Training as a tech rn. Can’t wait to get certified.

CALIFORNIA IS BUSY I HEAR
Dope shit, I want to get into ammonia. Looking hard a Cgap training.
Mask seal with that beard? Jk great on fly video stay safe!
YES IT DO
Ayy love it bro looking for knowledge new to refrigeration but ain't nothing cooler😂
YEA ITS A GOOD FIELD TO BE IN... MOST OF WHAT YOU LEARN WILL COME FROM THE JOB... WELL THATS WHATS GOING TO STICK... GOOD LUCK
RBG SLIP DUB O hey bro you still around?
🤣🤣🤣🤣 had me laughing at the gyglco . They are 2 different systems working as 1 .
I was talking about the line from the HPR to the Glycol system
@@inkosienkulu ya I know what u was talking about
Where is this? Which plant? Which city?
Did you say comprising air ?
(2:05) - What is all that ice doing there ?
>
The refrigerant inside the pipes (ammonia) is so cold that the gaseous moisture (water/humidity)on the surface of the pipe freezes
What state u from bro?
How did you get in, do you need a certificate?
RETA or CARO certification, is what the industry prefers. Most companies will train you and send you to school
No disrespect but how are you running that engine room by yourself?? What plant is this . Please be careful....
Oh go home will ya? You obviously know nothing yet you speak
@@steamdriver6964 me go home lol
@@justinp7020 yup go away you know nothing
@@steamdriver6964 I have 10 years experience buddy . You go away . You dum f
@@steamdriver6964 you go away . 🤣🤣🤣🤣
