Cleaning neglected cooling tower screens [HD]

Actually they were not deliberately neglected.
Once heat of summer hits I need to try and make it to the end of summer to do a complete thorough cleaning of the entire towers.

I couldn't quite make it as the black slime started to take over rather suddenly (need to shock it with some Chlorine) and were restricting the filter screens.

The small mesh filter screen at the pump was the real culprit and more of a pain in the butt. I have to clean it about every 2 months but I tried to make it until the heat of the summer was over.

This week the pressure dropped on my pump discharge and this AM was a nice drop in temp.

Next month I will shut down each tower one at a time to do some major cleaning.

8:43 Wow Wow Wow hold on a second, I dont speak Chinese!! Great Videos, really enjoy watching them. What part of the valley do you live in?

@HiddenValleyHVAC

NW Valley.

so those cooling towers chill the water with air or is there refrigerant circuit somewhere in the system to chill it? this is the type of system that uses inline coils in the duct system to cool different areas? heating is done with boilers?

@hvacbuck

The towers cool the water which is pumped into the chiller's "condenser barrel" to remove the het from the hot gas refrigerant. The chiller cools water to 45 degrees to cool the building.

You have a cool job, I'm in the residential side, but Im hoping to get more experience and hopefully jumt to some commercial. Does the company you work for do both? I live in AZ.

I work directly for the properties here fixing stuff on site ranging from the HVAC to kitchen stuff to misc electrical, etc. I no longer work "in the field".

It doesn't pay as good as being in the field but I like it. Pretty straight hours too. And 15 min from home.

Kinda scary that the black crud seems a little harmless there in tower sump, but damn near brings the system down by restricting the water flow. Good thing the temps were down and you had another chiller and tower in standby, in case there was some problem getting restarted. So many darn things to set/reset switching over the pump, could make a guy really tense on a hot day when max system capacity is needed. Good video!

Awesome video bro ! Looks great in HD.

Is that a Chicago Pneumatic air impact wrench or some cheap one? Snap On makes some nice electric ones, but they are about $500 dollars.

I forget what the exact tonnage was.

The building it cools is pretty big. 6 floors with about 250+ units averaging 1600 sq ft each plus a full restaurant, a dozen rooms at about 800 sq ft each, an entertainment room at somewhere along the likes of 5,000 sq ft and the main middle section at another 6,000 sq ft.

The one chiller cools it all here in the Arizona Valley. :-)

I've got a video up of it that I made not too long ago.

How Much tonnage you got out there on those Chillers. 30, 60 or 100 tons?
