First time seeing the inside of a water tower chiller, looks and sounds so cool 😮

The piping and the way its ran seems to always be an afterthought. I constantly run into poor piping practices...the building im on is a prime example....we do what we can....but dang....it can be a pain sometimes. Great video as always

u could put a 90degree elbow facing up on the upper overflow to save that water and chemicals. cut ur pipe going upwards to set water level when pumps off so its not pouring down the drain and then doesn’t have to fill every time pump starts

Man that was smart to change the ABB VFD ramp up rather then change the float! I bet that balanced out the system after that! Chillers wit cooling towers is the best commercial setup for cooling.

Looks like all that water is just from the supply line to the tower draining out. Realistically it should have been run lower and then step up right at the tower, rather than horizontal straight out of the tower. If you want to fix it, you could modify the pipework feeding the top of the tower and install an inverted P trap (P going up not down) just prior to where it enters the tower. That'll stop the water draining out of the entire supply line, only what's left after the trap. Probably not cost effective for the little bit of water it'll save, though.

Had an interview at Trane today for in house chiller tear downs. Man I hope I land that. 😅

Great Video as always. Thank you for sharing. What 's kind of water for use cooling tower ? fresh water , tap water or water mix with chemical ?

I work at a hospital in house and we have 8 cooling towers we work on. 2 are side by side and 1 always runs its amazing being inside the one beside it while the other is running. 4 Evapco and the rest are a different brand.

Hm, maybe the falling water influence the float (until the fan starts) more then normal. I have changed makeup water valves before because of this. Mostly bigger floats to counteract the water from above

Your float should have a nut on both sides to keep it from working it's way out. Those windage screens look plugged up too, should pressure wash those bad boys... Better airflow may cure that noise that you're hearing.

Good place to go swimming 😉

I still dont know why they use butterfly valves as circuit setters? i would recommend a plug valve and set it up and use the butterfly as a shutoff only just my two cents

1-st reason of overflowing during shut down: drain pump is stopped, but water inside of cooling elements still coming; 2-nd reason: drain system is dirty and don't allow to suck a lot of water; 3-d reason: drain valve is closed about 50%

2:59 next time first wait until overflow stops then turn on the pump and then adjust the fill float otherwise the tank will still overflow

Seems like that tower could have neeed an auxiliary sump to contain the overflow as with most tower jobs that I've seen but this is not my area of expertise

Motor control group 26. Code 2606 SWITCHING FREQ increase it from default 4khz to 8khz this will quite down the motor.

Surprised the system runs so high in the sump that normal stop start operation requires water loss out the overflow.

is it really that quiet in the plant...??? no way man.

Lower the water level..seems like a lot.

What a waste of water out of that overflow. Chemical guy hates you I bet… sump level didn’t seem to drop a ton on startup, can you get the fill level down lower without cavitation? Keep water from going out that overflow.

That honeycomb filter media has seen better days.... I bet there's plenty of problems at this site. Nice work on your part to fix the challenge and adjust the ABB Freq-Drive.
