So worth repeating....
Why complicate your garden with a chiller, when something as simple as a few layers of bubblewrap or some strategic shading can do the job.
I suspect a lot of the UK NFT growers who are suffering from Pythium problems may find that they start the problem when they plant out a new crop of small clones, plenty of spare light directly hits the top plate for many days until the plant canopy develops and shades it, the temps under there can get really high and it may be this that sets off the problem, likewise for DWC units and other systems.
did you say....bubblewrap? lol
