I really like the amount of explanation you give Mr. TY. Personally I enjoy your teaching the most but so will say HVACR videos, HVAC School, AC Service Tech LLC and Anti DIY HVAC are all great people. Thanks for making these videos because I’ve learned that people get tired of explaining the same stuff over and over and your videos with others provide super valuable knowledge that can be learned without the stress of asking a person to repeat something.
I'm honored to be mentioned amongst such great people. Thank you. When I started out, resources for learning where limited. It is great that we have so much available to us now and that I can help others. Thank you!
Very helpful breakdown of medium scale equipment! I'm working at a combined cycle power plant that has evap coolers for the air inlet of the gas engines for efficiency gains, and I've only ever had a surface level understanding of the concept. Where I'm living, I'm surrounded by data centers that are all hiring for operating and maintaining UPS systems and various cooling solutions. This video looks like it addresses what an evap cooler in that setting might look like and, more importantly, what problems and solutions to expect and implement in the field! Most other video results were about small scale swamp coolers for a room, which is the same process, but not very helpful to what I wanted to see. Thanks for the hard work and good teaching!
I like the second pump system the best. Basically, it is a blow down method, been used in steam boilers for many, many years. The cooling towers where I work has a sand filter system where accumulated mineral deposits can be removed through a blow down. We use a chemical free method of controlling mineral deposits.
I live in Colorado, I love my swamp cooler! Best $500 I've ever spent! I have only had to replace a pump and a couple of belts. My home is 920 sqft and it cools the whole house down!
I worked in Las Vegas for 30+ years maintaining Evap coolers as part of HVACR service and without bleed off or pump down those coolers would scale up within months. I liked using Coolpad vs. aspen pad. Mastercool celdek coolers were the best for providing the coolest air.
Awesome! First time I hear about these units, then again I'm pretty young in the trade... Very good explanation, hopefully I never have to work around these units, but incase I do, I now have a better understanding of them..thanks ty...👍
Thanks for doing this demonstration with a rusty system because its more realistic. I learned a lot and I really like evaporative coolers for dry environments, man it feels good, and I like that its an evolution of ancient wisdom and technology. I wonder if newer evap cooler systems have a better protected motor because my evaporative cooler gets absolutely blasted with the evaporated water and when it dries that calcium cakes it up. I probably just need new soaker panels haha, once a season and Im over here reusing it for several seasons, thats probably my main problem.
Try a calcium filter and a pump to flush out the sedements. Some of the newer models use use a cartridge style evaporator instead of pads and they use sealed motors with plastic fans and fan housings. Calcium dissolvers can be used in them since they are plastic. I think they are better but they are pricey!
Great question, I'm sure there is a way, but I imagine it would be a nightmare. They usually end up rusting before getting dirty. I have washed them in place before. Also once the feed water is treated, the wheel clears up. They don't get dirty like the blower wheel for ac since all the air is outside and the water and pads acts like a filter.
There is a way to remove the blower wheel but it is a long drawn out process and if you're in the trade it might not be economically feasible > time and materials. I have done this on my cooler and for a dozen or more customers coolers.
Seems to me putting treatment in the pan is not going to do too much for these systems,I'm in new england,I've never seen one before but I'm experienced in water treatment for feed water systems and what's going on with fresh water being added daily to these systems is not going to be controlled by adding chemicals to the pan,especially on the ones that pump out like you say. The best thing would be to filter and run the water through a softener system before it feeds the unit,better yet an r o and a softener, then you could probly get 5 years or more out of your pads and 3 to 5 times the life out of the unit itself.
I should have covered it more than just a picture but we use a descaller filter on the inlet water for all units. The pump is certainly the better choice over chemical tablets although we do have some now that treat for bacteria with a controlled release. The RO would be awesome. Although I don't think I have ever seen one in a unit. In cooling towers we have chemical pumps that add in a chemical for every x gallons of water added. When the chemical person messes up it does a lot of equipment damage. Some of the new coolers use a crate style cartridge that performs better and lasts longer. I believe the port-a-cool units use this same style. They last several years. I guess it would come down to cost vs replacement at some point. Great comment and insight.
@@love2hvac yes cost is always what it seems to boil down to lol but if I lived out that way and this is the type of unit I would have in my home forever, I think I would invest a bit into water treatment for sure, they sell small inline r o systems for 400$ or so for an entry level decent one, water softener setup around 1200 in materials if you could do install yourself and save money there, I know you can,I mean other viewers or the average homeowner. But ya I'm sure there's people who do install these things for there systems, it's not like it's brand new technology I'm sure the installers try to push for it out that way
I do think it's a better way of cooling for a dry climate. You get a lot air exchange in the house pushing out off the air contaminants from all the products in the home. It uses much less electricity and the extra moisture in the air is good skin nose throught and eyes. I want to try the RO or softener system now. I agree that would make a big difference.
The inline scale/filter is a misnomer. The scale cartridge contains polyphosphate, a compound that helps to sequester calcium and magnesium salts, thus reducing the tendency of calcium to harden and salts to corrode metal surfaces. The r/o is a better idea but you would need a storage tank to supply water to the cooler in between r/o operation and flushing intervals. As for a salt based water softener system, why would you want to add more salt to your feed water ?
@Anthony Gonzalez you wouldn't be adding more salts to the water, you'd be reducing cal mag and other dissolved solids. This is done before you send the water to an r.o. otherwise you'd just plug the membranes up in a short time. Although phosphates do react with calmag to turn them to a dissolved state in a boiler feed application, it's always best to remove as much as possible before it gets there as chemicals are only partially effective at their jobs. You need a combo of both external and internal treatment in those cases, in this case with the swamp coolers, I was just thinking it would be best to pretreat so you don't have to guess if the tablets or inline filter is working efficiently. It could mean the unit lasting 15 or more years longer was my thought
I have an evaporator cooler that is spitting/ sputtering out water from the supply air. The float is working correctly and isn't flooding/ doesn't have water near the blower housing. Any idea what is causing it?
Check the gutter tray at the top. sometimes they start to clog and overflows out of the tray into the blower. Check the pads, once they get frayed or mineral solidified they will pull water off Since it is the end of summer, sometimes its more cost effective to slow the blower down and replace the pads next spring.
If the pump is too large ( head pressure ) , too much water will be supplied to the water troughs and they will flood causing excess water to be splashed out into the coolers duct ( this is called " water entrainment " ) .
We have a similar roof system but it's constructed with plastic (lower section) and stainless steel (upper section and panels), seems like the colorbond steel construction is a poor choice for the consumer.
Awesome! The narrative that you present on this video is outstanding for beginners, thank you so much…

Very informative. I just bought a house with one. Thank you.
Glad I could help

They need to make the whole thing out of stainless steel, I am going to build 1 outta stainless steel
Thanks I just bough house with this old unit and it looks bad.thank you Mr.TY
If it's in bad shape just replace it and maintain the new one.
I have wasted many houses trying to save old ones.
I run em till the wheels fall off. Its still good.
Beautiful video brother 🙏 so helpful
Thank you so much for all the videos and explanations! This dirty blower wheel can we pull and clean out or there is no way?
Great question, I'm sure there is a way, but I imagine it would be a nightmare.

What do you think about the Eco pump Have you ever seen it Check it out
Thanks for sharing! I have not seen that before. I just looked it up. I will have to get one and try it.
Seems to me putting treatment in the pan is not going to do too much for these systems,I'm in new england,I've never seen one before but I'm experienced in water treatment for feed water systems and what's going on with fresh water being added daily to these systems is not going to be controlled by adding chemicals to the pan,especially on the ones that pump out like you say.

how long to soak pads
I have an evaporator cooler that is spitting/ sputtering out water from the supply air. The float is working correctly and isn't flooding/ doesn't have water near the blower housing. Any idea what is causing it?
Check the gutter tray at the top. sometimes they start to clog and overflows out of the tray into the blower.

After watching this video...I will never buy or use a swamp cooler
You’d think they’d make these out of stainless steel or aluminum so that they don’t rust
Lol mines nearly 60 years old only hadto replace the water pump and a belt so it's so worth it
Good for you.
@@vidademikey9790 it will be good for me
