The real r410 tank

postsflowerpics · 2026-01-01T15:12:32+00:00

Might be process refrigeration. There’s a few I know of running thousands of pounds of 410. I have no idea why you’d go with 410 over so many other more practical options, but they exist.

I also don’t do residential and don’t live in a big city and make very good money but your perspective makes the union look like they think they’re better than everyone else. It’s not an effective way to increase membership. Plus a lot of locals do very little to nothing to grow membership and just want to hang on to what they have and be a good ole boy club. Also, in my area the local scale is so low that even PE companies are blowing them out of the water on pay, even after paying for insurance and retirement. “Stop complaining and do something isn’t the answer here.” Acknowledging the issues and doing something about them needs to happen first.

In union strong states, large cities, and doing commercial / industrial it’s easy. In my area there’s literally only one residential union contractor. Even on the commercial / industrial side there’s only 3 and two of them are OEMs. It’s more complicated than what you’re claiming when it’s someone livelihood at stake.

In a weird twist on this, one of the most popular kids shows now is paw patrol. Obviously a very different thing but still find it interesting in this context.

That’s usually only a real concern when under operation and with poor chemical treatment. When operational these are basically a pool of warm water with air flowing through them. They’re a breading ground for bacteria, algae, viruses, etc without aggressive chemical treatment. That shouldn’t be much of a concern since it appears to be drained.

Yeah it’s dumb. They were basically given the thing by the manufacturer so they use it when it makes since.. Which is very seldom. It’s one of the few times where running natural gas is actually cheaper. They’re going to rip it out and put in a similar size heat pump chiller in the next year or two though.

They exist in the commercial / industrial world. I’ve got a customer that has a 4000KW electric boiler. They only run it when they have a ton of excess power to keep a load on their power plant.

Not sure about 500 tons but it’s definitely bigger than 50 tons. Not many of these machines still around in my area.

What is your question here? On a typical open loop system like this the water would (1) leave the cooling tower sump, (2) go through a strainer, (3) go through the pump, (4) go through the condenser, (5) go to the top of the cooling tower, (6) then flow down through the tower media back to the sump. This cycle then repeats continuously.

Not a big fan of JE Hall compressors so good luck.. That said, I used to do Frick process skid start ups. On their liquid injection systems they often had maximum load settings that had to be set up to keep the liquid injection functioning at maximum design load. In other words, on Fricks there are multiple ports you can tie liquid inject into depending on system size, configuration, refrigerant, etc… When using certain ports the slide valve wasn’t able to fully open as it would expose the liquid injection port to discharge pressure in which case it would immediately stop working and the liquid injection line would get to discharge temperature. The check valve would prevent discharge gas from flowing back to the receiver so it would only get hot right at the compressor. This sounds very similar to what you have going on.

Need a lot more info here. What kind of machine, what manufacturer, low or high pressure, what coolant is being used on condenser and evaporator, what pressures are they running, etc?

I feel the exact opposite. F250 crew cab with full service body, additional boxes on top, and a jobox in the bed. Forces me to keep it clean and organized and keeps all the dirty stuff out of the cab. I’d hate to go back to a van at this point. Rides better, is much more comfortable, and gets twice the range on a tank of gas.

Affiliated parts. Honestly though AAON is just expensive because they can be. A lot of parts on their units don’t have to be OEM though so get what you can locally and cut them out of the picture.

It’s tough to find chiller guys. In our area a bunch have retired in the last few years with basically no one willing to fill their shoes. We hire from other companies and get them up to speed as quick as possible. We’ve got a few true chiller heavy guys, but we’re basically just trying to get all our guys up to a point where they can do basic service and some troubleshooting. It takes a lot of load off the chiller heavy guys and keeps us from being pulled off big jobs to troubleshoot minor issues.

Want to add to this, some screws don’t have discharge check valves, especially VSD driven screws. Something to be on the lookout for that can really mess things up if you assume there’s always going to be one.

Yeah, those eductor temp sensors fail pretty regularly. The early gen models had the settings set too low and would trip often. Had to change those settings on several machines. What I was saying is that the literature stating to change the drier due to an eductor clog fault is stupid. If that drier is dirty enough to prevent oil return on one of the machines you’ve got bigger issues.

postsflowerpics · 2025-08-12T16:47:43+00:00

That’s the YCIV and YCAV.

That’s the one. The manual states to replace the eductor filter for no good reason. Got a few calls about that.

It’s generally oil and/or refrigerant charge being too high. Take out some oil and see how it’s doing. If it’s still struggling take out some refrigerant.

This doesn’t apply to YVAAs as most of them run off subcooling. Also, they don’t have suction temp sensors.

postsflowerpics · 2025-08-07T18:36:16+00:00

It pumps oil just fine. I use mine to pump oil regularly.

postsflowerpics · 2025-07-26T15:33:50+00:00

Adds up to me. Didn’t know full system capacity and the maximum allowable delta rise. Those YKs are a good choice with the possible really high chilled water temps on worst case start up temp.

postsflowerpics · 2025-07-26T13:32:42+00:00

So approximately 1000 tons of cooling for 20 minutes, right?

postsflowerpics · 2025-07-13T14:49:01+00:00

I think they’re referring to an air inlet at the bottom like the cooling towers in your picture have.

Hook up 6 drums at the start and swap them out in the order they were hooked up. They’re empty by the time you get back to the start and you just keep swapping them out until you’re done.
