12000BTU enough?

[dirk_brijs]

I will be setting up a 375Gl DT and complete water volume would be 700Gl with Fuge and sump included.
My regular water temp reaches 86F and I would like to reach a constant temp between 77 and 78F
I have currently a 12000BTU chiller available from my current system.
Would this chiller be big enough for the new system?
Or would you guys need more info on the chiller to actually calculate this?
Thanks

can anyone help?

I take it the chiller you have is roughly a 1hp unit? Should be fine, but depends on what brand, water flow through it & how you have it plumbed. Incorporate fans aimed at water to cut back on how often the chiller runs, watch your evap rate though.

I believe its a 1 1/2Hp unit and it was costum made by a local airco shop here who is into aquariums himself and builds chillers for aquariums.
its connected to a 1500GpH pump.
for the system I have now (1100Gl) it works real well. Takes less then 1/4 Hour to get my water down back to the required temp with a 1F influx.
But as said it will be 2000Gl plus system I am building now?

I'm confused, I thought you said you're building a 700 gallon total volume system? Either way, if it's 700g system it won't have to come on as much, if it's a 2000g system it will work harder but still be sufficient. Just aim fans at the sump water and fans at the lighting, they help huge. Water flow of 1500-2500gph should be your target, higher flow end if your setting up a 700g system or slower flow end if it's 2000g.

sorry bout that got my liters and gallon mixed up lol

LOL, that chiller should be ok with a lot of fans but might be overworked resulting in a big electric bill. If money isn't really an issue, then I would get a chiller in the 18000-24000btu range. Doesn't Thailand get really hot? I have all my fans controlled by an aquacontroller 3, and I have a lot of them.

it tends to get hot here at times yes about all the times lol

lol, good luck with the build stay cool
