Have you all seen these? BrewUK and HBC been touting them.https://www.brewuk.co.uk/gf-glycol-chiller.html
They are stupidly priced - £400 for the FV and chiller is £800! They justify it with the claim that it can control 4 FVs at once...so thats £2400 for the privilege.
I'm sure they are great, but I really can't see too many people indulging. The FVs are too small for a commercial microbrewery but out of most home brewers price. Not really sure what they're thinking by launching these.
It's cheaper to buy four brand-new fridges. Probably cheaper to run too!
