Wow. That was very good. Maintenance is key to equipment longevity and preventing unplanned down time. Unfortunately companies under bid and don’t provide techs sufficient time to do the right thing. Over greasing is my biggest pet piv. Thank you for this presentation.
I wasn’t aware of over greasing being an issue. What could possibly happen to bearings if there over greased? What’s a good rule of thumb for how much grease to use? Thanks
I have seen some nasty towers over the years. I had one customer that had tower no sales and strainers so plugged, that the machine was doing a 28 degree temp rise on the condenser with the machine only loaded to 30 percent lmao
I took over maintenance of a chiller and a tower in an 8-story apartment building. The residents had been complaining for a couple of years how warm it was. I went up into the shack and I just about quit then and there, but, I sometimes like a challenge and this was going to be one. The chiller was okay but the condenser was a disaster. The fan motor was out, The fan bearing was seized, the belt lay in pieces on the gravel, the waterfall and sump were totally blocked with scale-mr. fremont hadn’t been through in years. The pump in one leg of the building was burned out. Those residents were paying some pretty good money to live there too. Took me about four months to clean up and fix the mess and get the water back. Then it was time to start going through the blowers in all the apartments. The coils were plugged in all of them and I had to replace over 20 motors. A few of the squirrel cages were locked up. I moved on three years later leaving one sweet-running plant for the next guy. That was what I call a very satisfying job.
Great video. If I could just correct him on one thing, The louvers above the fill are not inlet air louvers. They are drift eliminators. Their purpose is to collect water vapor so it can drip back down instead of going out the top through the fan.
You guys touched on pretty much all service points. Just an FYI, a closed loop tower is commonly called a fluid cooler too. Which has many advantages over an open loop. The use of the fan without the water in the basin, use of the spray pump separately with no fan, or a combination of spray pump and fan for higher load days.
Really helpful and knowledgeable. I do not do chillers but am interested into getting into the field of it and this was really helpful. Keep up the good work 👍
Manny did a great and through explanation. He knows what he is talking about. This channel's presenter is a novice. Manny is a pro and can explain everything.
Great vid. I see you standing inside the tower with a ladder next to you. Isn't that considered confined space are? I know it would be for us unless it was declassified, I would recommend replacement with all the structural cracks. Upsell!!!👍👍👍👍👍👍👍👍👍👍
Great post. Unless I missed it, our PVC? inlet air louvers are directional. Many different vendors have worked on both of our cooling towers due to emergency availability. When I started doing my own PMs I found them all installed so the water would be diverted to the outside of the tower. Not being able to find any firm answers from our local vendors, I turned them around. It would make sense to me that you’d want any splash or residual water going back into the tank not out. Did I do the right thing? Excellent info here.
Can Manny or yourself do a video on Well-Water systems? I am seeing these more often lately on accounts in the Caribbean. I’m sure it’s becoming more common due to advances in technology. 👍🏽👍🏽👍🏽 great work everyone!!!
After doing 2 years of light commercial. I applied for an entry level hvac position at a hospital. They have 2 cooling towers but unfortunately we do not service or mess with the chiller, Only the air handlers. I wish I can get my hands on the equipment
Up by the motor and fan we call those mist eliminators. We also have lots of fluid coolers for towers. Most companies here have companies that specialize in towers perform the PM. We occasionally change the belts and fill and air inlet fill.
I work for a company we pressure wash that whole unit and we treat the tower with are in house chemicals blends.we clean them out every 6 months to 1year we clean out alot dirt and algae off ....Apollo technology .. in California
Hello I am a supermarket refrigeration service technician and looking to go for chiller service technician. What do I need to have to become chiller service technician and what is life compared to supermarket technician?
Ok is it a counterflow tower or crossflow tower? Counterflow towers have spray nozzles. Crossflow towers Ave a pan at the top and the water comes down via gravity and condenser pump discharge force
What happens when the water pan is over flowing? I had that happen one point but that was years ago. I don't remember if they turn off the tower or the open valve didn't open and had to open it manually...
What are your thoughts on this industry as far as a later introduction to the trade ? I’ve been in the trades for decades and now maintenance for about 6 years. I learn readily but training g is limited unless I’m with a great tech . Would apprenticeship be the way to go ? I still have a lot of interest. Thanks
It is a very tough situation the trade is in as a whole. If you can find a really good company that has good techs to be an apprentice at that is very beneficial but that's not a whole lot different than just working with a company that has good techs. It really is one of our biggest issues right now, we've lost so much of our senior experience. Those of us that are left are having to train a large volume of people at a time and it is very difficult at every company. One great thing is there is a ton of opportunity in the trades right now to do just about anything you want, but it's because of the lack of experience as to why those opportunities are there. What this means is that those who are willing and capable will have to strike their own way more than they'll be able to be trained. I hope that makes sense. And is somewhat encouraging or gives some form of direction?
If the pump fails the chiller would shut down on the safety flow switch. If the tower fan fails the chiller would shut down on pressure switches after a few minutes
This is off topic, but I have a similar system and looking for ways to conserve power while tenants are not in the building (Fri-Sun). Can I turn the 4 AHU's off, there are 2 on each floor, 2 floors. If I turn the AHU off, what actually keeps the water circulating in the closed loop water chilled system? Thanks
If you turn the AHU off water will not flow through your coil cause your actuator will close but your circ pumps should stay on moving the water. Find out where your circ pumps are
@@HVACTIME : I found a small cooling tower in a 6000 sqft. mansion in New York. It cools the compressors on a series of giant AC units. Water cooled AC! But I thought evaporative coolers really only work in very dry climates. Who knew?
The powerloss and inefficiency of a belt driven fan is insane. You lost almos 90% in the worst cases the power from the motor, it means your powerbill gets inflated and your building overheated. instead of a direct drive that has 0 power loss... thank god engineers noticed that... a little too late but they did notice.
Ok I don't hear nothing about the wet bulb temperature design, the approach temperature, blade tip clearance, density ratio, angle of the blade. I see that the tower has 5 blades, therefore angle of each blade should be 72°. He didn't speak on the importance of how to calculate evaporation rate etc.
I didn't hear anything about cooking tower effectiveness and how to determine the efficiency performance of a tower. Tower fan should not exceed 0.30kW/ton. Did he even mention tower approach. I can see in the video that the tower is not located in a good place, is boxed in surrounded by a wall & structure too close to it. Tower is located in a very low spot

4:09 Doesn't he mean supply from the Chiller?
really dope info, i can see y’all getting huge if yall keep it up!
I'm moving in to larger system HVAC work and this is a great video for learning. Thank you and keep up the good work.
You guys are awesome with all the helpful info you provide. Thank you.
Guys well explained. This is one of the best videos have watched on RUclips.
Thanks Manny for the tour. We had one of these at my school always wanted to know how it worked.
Nobody can teach like you very good sir
Really really good, very well explained. Thanks
Wow never seen inside a cooling tower amazing 😊
Thank you for a good explanation on the intricacies of preventive maintenance! Love this video!!
This shows how to do a complete inspection on a large item of HVAC equipment.
Is it typical to have a written checklist for this type of procedure?
Thank you very much indeed for such a detailed and informative explanation.
Very thorough rundown, thank you 🙏🏼
Thank you
Underrated Chanel
Top of the line. explaining, much appreciated
Nice video, great knowledge and experience.
Thanks for sharing
Thanks for the video just transferred from residential to commercial and thought this was great!!
im in texas so yeh our towers take a beating more than 6 months out the year... we do our pm bi annual before summer and before winter
Nicely explained working of cooling tower at site, thanks
Finally a better understanding of identifying a closed loop system 🤙🏼
Great description, our condensers fans are belt driven. But do just about all the same things.
Very much appreciated.... great explanation🎉🎉🎉
That's literally so COOL!

It has to do with air flow direction. Its intended to direct the incoming air evenly across the fill.
@@HVACTIME so is what I did correct then, facing inwards? Thanks for the reply btw.
Good break down, thx for sharing.
This is good stuff. Thanks man

So when is the best season to “pm” a cooling tower? Thanks for sharing your videos
Great stuff and thanks from London England
Very informative, thank you!
Let’s go all my HVAC brothers
Intresting👨🔧
Do like to share this very informative cooling tower maintenance, please.
Up by the motor and fan we call those mist eliminators. We also have lots of fluid coolers for towers. Most companies here have companies that specialize in towers perform the PM. We occasionally change the belts and fill and air inlet fill.
Ya thats definitely not the norm here
Thanks for the video!
I gave your channel link to a buch of apprentices and I’m surprised how fast they catch on between that and working with it daily
Great explanation
Great information 👍🏿👍🏿👍🏿
So what do you do about the cracks, also do the safety switches get stuck with so much rust and humidity?
replace the metal plate
Great video
I work for a company we pressure wash that whole unit and we treat the tower with are in house chemicals blends.we clean them out every 6 months to 1year we clean out alot dirt and algae off ....Apollo technology .. in California
Great video 👍🏿
Wow thanks for the knowledge 🙏🏽
How would i as a 10 year commercial refrigeration tech get in this field? I have a lot of mechanical background as well
Hello I am a supermarket refrigeration service technician and looking to go for chiller service technician. What do I need to have to become chiller service technician and what is life compared to supermarket technician?
I like this channel
Thank you!
Ok is it a counterflow tower or crossflow tower? Counterflow towers have spray nozzles. Crossflow towers Ave a pan at the top and the water comes down via gravity and condenser pump discharge force
What are the temperatures entering an exiting this condenser unit?
it's 30 entering and 25 centigrade leaving. Generally it's about 5°c difference
What type of Fill does this tower have? and how many cells does the tower have? There are two types of fill. Splash fill, and film fill.
What happens when the water pan is over flowing? I had that happen one point but that was years ago. I don't remember if they turn off the tower or the open valve didn't open and had to open it manually...
Tower overflow in most cases is caused by faulty ball valve
@@davepeera1247 it wasn't. I figured it out it was clogged holes on top of the CT
@@bluecavemen ok.guessed it was the bottom basin
a full 8 day from top to toe. love this video
Excellent video
Does vibration switch in cooling tower a "must need?'" Or it is just optional for the more safety of equipment?
It is optional but it's a critical safety that will prevent extreme damage
@@HVACTIME thanks for your response. Can I integrate this to a crossflow type of cooling tower?
How much would a maintenance like this cost?
Yes!
What are your thoughts on this industry as far as a later introduction to the trade ? I’ve been in the trades for decades and now maintenance for about 6 years. I learn readily but training g is limited unless I’m with a great tech . Would apprenticeship be the way to go ? I still have a lot of interest.

What exactly happens to the chiller when the water cooling tower completely fails?
If the pump fails the chiller would shut down on the safety flow switch. If the tower fan fails the chiller would shut down on pressure switches after a few minutes
This is off topic, but I have a similar system and looking for ways to conserve power while tenants are not in the building (Fri-Sun).
Can I turn the 4 AHU's off, there are 2 on each floor, 2 floors.
If I turn the AHU off, what actually keeps the water circulating in the closed loop water chilled system? Thanks
If you turn the AHU off water will not flow through your coil cause your actuator will close but your circ pumps should stay on moving the water. Find out where your circ pumps are
Solid
Thank u for very good video 💪👍
So this is kind of a huge evaporative cooler, a swamp cooler?
Yes
@@HVACTIME : I found a small cooling tower in a 6000 sqft. mansion in New York. It cools the compressors on a series of giant AC units. Water cooled AC! But I thought evaporative coolers really only work in very dry climates. Who knew?
Its based on wet bulb. The lower of wet bulb the climate is around the tower the better performance it will have.
Great Vid
Thank You...
Would it be better if the tower was made out of Stainless steel?
Yes but VERY expensive
@@HVACTIME Do you know anyone that has made one out of SS in-house? It looks like a good challenge but not impossible.
Can someone explain heat sinks in a cooling tower ?
What can cause the basin water temperature to increase?
Poor water circulation..
Choked filler assy
Choked air intake
Defects in fan motor or blade
I'll be rewatching this one allot 😂
Does anyone know if most cooling towers are cleaned by the repair companies or by tower cleaning comp?
We service, repair, and maintain them. But we also do chillers so we are a complete package
Do you guys shock the tower before u guys do pm’s on them?
No, only when customer requests and they have their chemical company do it.
Hi.
Does anyone knows a Legit online HVACR program/training or institution?
Thank you.
I work for a company that clean all the inside eliminaters of that and teat water also ricks,Evap co..
Good luck
Safety first people! before all these steps and going inside the tower make sure to lock out tag out all disconnects!
❤🎉🎉🎉
U didn't talk about pitch angle of fans
The powerloss and inefficiency of a belt driven fan is insane.

It’s like a giant AC system
Instead of gas it’s water
Did he say pecker head lol
Yes thats what its called
No those are "drift eliminators" not inlet air whatevers.
