water coolers!

I don't use one but if I had to snag one with condenser coils I'd def grab a vevor one or something not grow branded (just regular aquarium chiller). You can also just grab a single or multiple TECs setup for fluid flow, usually for experiments or computer cooling devices for about a fifth of the price of a model like above. The TEC style is going to not really care about a filter for the chiller, less efficient than a refrigerant based one. If you use a sterile system with flow descalers, you could get away with an inline TEC or two. Most brands will have an entry unit for a few hundred bucks for a refrigerant version pre-filled with coolant. Vevor gets you 50 gallon chiller for two hundred or 90 gallon for three hundred or 500 gallon for under eight. I mean for a few hundred you can get a true laser engraving dedicated coolant system for water like below 20C if you wanted from vevor. Long story short, if you live in anywhere in the West...these chips only come from 1 of 3 places....the parts come from 1 of maybe 6 places....so check Vevor before paying ten times the price for something some already rich person paid a Chinese company to dropship from a western country.
