Hey i'm new to the forum

I am currently working on a machine where two small modules (around 30litres each) have to be cooled to 2-5C from room temperture. I am looking into a few idea, using a refridgerant system.

One is to chill a small water tank of water with peltiers and pump the water around the two modules cooling them down. I was looking at controlling the temperture in the module by the limiting the flow etc.
Another is using a danfoss refridgation system to cool both down. But unsure what is needed as it is not my field (only started as a mechincal engineer a few months now).

Any Help is appreicted
