Tower water temps

[indoorcomfrtsl]

It sounds like you might have a bypass somewhere in the piping. Can you check the suction and discharge of the pump and look up the curve? I would also want to know what pressure drop is reguired across the barrel.

I'd start with cleaning the strainers at the pump and in the tower.

You should be able to get within 6-8 degrees of wet bulb.

Maybe there's a tower by pass for minimum temp, and it's not modulating.

Might also want to check if tower has modulating dampner on fan..is it open?

[largetonnage]

not really. is there a method for measuring GPM w/o a flow meter?

GPM2 equals GPM1 times square root (deltaP2 divided by deltaP1)

gpm1 equals design
gpm2 equals actual
delta p1 equals design pressure drop
delta p2 equals actual pressure drop

don't forget to also check the spray heads and trees for blockage. and if you're growing algae, you may have other bacteria thriving - i.e. legionella - be careful!!!!!!!!!!

What kind of tower do you have? Is water going over the top of the tower? Or maybe running through a bypass? Hot deck plugged up? 110*h20 pretty darn hot. Not to sound like an a$$ but is the fan going the right direction?

lol, funny you mentioned that. it was one of the things I checked when I looked at the tower.

what is the brand of tower and model...your looping tower return water with towering entering to the chiller someplace.the tower will only do its 10F as you have typically.
