Would you scoff at the notion at paying $1,400 for a recirculating liquid chiller? If so, then Koolance's EXC-800 portable 800W chiller isn't for you. For those who don't mind spending a small fortune on big time cooling performance, Koolance will take your money in exchange for the EXC-800, which offers four configurable temperature methods, including the option to lock liquid to ambient temperature to avoid condensation.
It can also lock temps to an external K-type thermocouple sensor, though you'll need to provide your own. What it does come with is an integrated Koolance PMP-500 pump with a maximum coolant output of 2.9 gallons per minute. You can adjust the pump speed with 10 level increments while keeping an eye on the pump impeller speeds in RPM, coolant flow rate in LPM/GPM, and condenser fan speed in RPM.
If you don't plan to fixate your eyeballs on the chiller at all times, there's audio alarm you can configure based on temperature. There's also a relay trigger around back that can be configured as NO or NC and adjusted based on temperature.
