Koolance shows off the EXC-450, a portable recirculating liquid chiller rated at 450W for cooling your liquid loop to sub-zero temperatures. The unit is priced at $1,499.99.
Koolance's EXC-450 is an extremely compact (6in x 8in x 21in, or 152mm x 203mm x 533mm) portable recirculating liquid chiller rated at 450W, or 1535 BTU/hr @25°C liquid & ambient. Chiller control is based on one of four configurable temperature set-points, including the option to lock liquid to ambient for avoiding condensation or to an external K-type thermocouple sensor (not included).
Along with temperature and set-point, EXC-450 can report internal coolant flow rate, pump RPM, and condenser fan RPM on a customizable 2-line OLED display. An adjustable relay trigger output on the rear of the unit is available based on temperature.
Cooling capacity: 450W (1535BTU/hr) @ 25°C liquid/ambient
Temperature options: liquid set-point (1 to 50°C), external thermocouple set-point (1 to 149°C), liquid and ambient delta-T (-50 to 50°C), external thermocouple and ambient delta-T (-50 to 50°C).
