Cooling 2 tanks with one chiller

Recommended Posts

Needing to chill two small tanks 18" x 9 x9 with one chiller tanks are undrilled and don't really want to drill them, I want this to be cost effective. Chiller is a 250amp hailea.

The chiller is rated to 500lts so your tanks fit the bill there.

Possibly only a bit of plumbing required.

Tee off the suction line to your pump, install a valve on each leg, place one end in each tank.

Tee off the outlet from the chiller, install a valve on each leg, place one end in each tank.

Now, to help the whole setup out, the length of each leg 'after' the tee, should be as close as possible in length to the other line that shares the same tee.

Now, open All valves Fully, start your pump, a bit of fine tuning with your valves and you should be able to equalise the flows to maintain the levels in your tanks.

But please note, should flow in one tank be obstructed for Any reason, you are going to have a wet floor.

You could also consider a siphon overflow type setup,,,,similar to some sump systems.

Have fun.

If you want economical than use a water bridge to join both tanks. Pump from one tank through chiller and return to other tank. You won't be able to pump very fast with a water bridge. Use two bridges as they do clog and slow down. You only need to sieve the input side of the bridge. Google will show you how to bend PVC pipe into U shapes easily.

If you will be filtering on the same water circuit, filter before the chiller as bacteria aren't as active in cold.

I would do a water bridge, t-ing off is just a recipe for disaster. Or you could do overflow boxes and run a sump, chill and filter the sump and run up to the tanks... That's a lot of effort though.
