Cryodax looks really good from a $/kW standpoint, downside to them is they need another cooler or source of cold water to handle the liquid loop since they don’t exchange heat to air.
I’ve been really impressed by Chillkings offerings, downside is their LT series units don’t get very cold. But they are great for falling films and getting things down around or slightly below 0C.
We just took delivery of a Fluid Chiller but don’t have it up and running yet. Lead times suck but thats true of every industrial supplier I’ve talked to in the last year+
Lots of good information in my bitch thread about Huber: Who sells huge cryo chillers that aren't huge disappointments?
