Chiller questions

Need some help here guys. As part of a research lab that I am a part of, I am setting up a holding tank for a cold water sea urchin species. Roughly 54 to 60 degrees F. These will be harvested for their gametes and used for embryonic research. Anyway setting up the tank is easy but I have never run a chiller. Ill need two. One for the mixing tank and one for the holding tank so that their are no temp swings. The holding tank is a 55 gallon with about a 10 gallon sump that im making and the mixing will be a 29 gallon. What hp chiller would be enough to keep these running in the range listed? Preferably the lower end of the range? Cost is not an issue but I am trying to be economical. I was looking at these.

That looks like itd give me roughly 20 degrees of cooling for a 60 gallon total volume which puts me right where I need to be. Thanks ill look into it. Any others?

It depends on your ambient temperature of the room. They always exaggerated the capacity of the chillers. You are going to need one that is much bigger then what's stated for your water volume. The temps you are keeping are much lower then what the average person uses a chiller for. Good Luck!

I assume room temp. Never being higher than 72 degrees. Any reccomendactions? How about thw 1/6 hp version of this for the holding tank and the 1/10 hp for the 29 gallon mixing tank?

I would oversize it. JBJ has a good calculator on their site. Make sure to include all the temperature factors like pumps and lighting.

I have decided on the pacific coast ones. the 1/6hp and the 1/10hp. My last question would be if these come with everything needed to set them up? I assume it will have a return and an uptake hose and i just put one in the sump and one in the tank itself? it does not need to look nice as this is a holding tank not a display tank

I'm no expert, but I think you are a little undersized.


You will also need a pump at the flow rates specified for that chiller.
