Cooling down the water in a 1000 liter container

When I use 1 1000 liter container that water is in about 1 till 2 hour 30\40 degrees celsius when I drive the laser with DC 30A secondary current. The laser needs water with a maximum temperature of 30 degrees celsius, and 8.5 liters/min or 2.2 gal/min

Is there a way to cool the water down to about 10 degrees stable? Please keep in mind that the laser must be able to run the whole night.

Worst situation, 1000 liter was heated in hour from 10 to 40°C.
So you need a cooler of 1000 x 30 x 1,16 = 34 kW.
MOost positive situation : 1000 l in 2 hour from 15 to 30°C =
1000 *0.5 x 15 x 1.16 = +/- 8 kW.

So your figures should be more precise to calculate your machine.

I should go for this configuration for a Rhoss (relative cheap and good quality, everything build into it, pump, buffer, made to install outside..) of +/- 15 kW.

You can also consider to install 2 independent machines so that you will have a safer setup. If one fails, then you always have the other one as a backup.

You will need +/- 20 to 25 l/kW so 500 l should be sufficient.
