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). Select only values you want displayed on the front 2-line OLED display (fixed or rotating) Adjust pump speed with 10 level increments Show pump impeller speed in RPM Show coolant flow rate in LPM/GPM Show condenser fan speed in RPM Adjust audio alarm based on temperature Relay trigger can be configured as NO or NC and adjusted based on temperature Refrigerant: R-134a Power input: 24VDC, 250W or higher Maximum power consumption @ ambient (approximate): 230W @ 25°C Designed for an operational temperature range of 0-40°C (ambient and liquid) Reservoir capacity: 1 liter G 1/4 BSPP threads on back for fittings
NOTE: Requires 24VDC input power. Keep unit upright at all times, and for at least 24 hours before applying power to ensure sufficient oil reaches the compressor.
