(NOTE: Rev.1.7 of this product has changed the rear fitting threads from G 1/4 BSPP to NPT 1/4in.)

Koolance's EXC-800 is a portable recirculating liquid chiller rated at 800W, or 2730 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-800 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: 800W (2730BTU/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); toggle °C/°F
  • Pump: 10 manual levels, up to 11LPM (2.9 GPM)
  • Select only values you want displayed on the front 2-line OLED display (fixed or rotating)
  • 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: 110VAC, 60Hz
  • Maximum power consumption @ ambient (approximate): 450W @ 25°C, 650W @ 35°C
  • Designed for an operational temperature range of 0-40°C (ambient and liquid)
  • Reservoir capacity: 3 liters
  • NPT 1/4in threads on back for fittings

NOTE: Requires 110VAC, 60Hz input power. Keep unit upright at all times, and for at least 24 hours before applying power to ensure sufficient oil reaches the compressor.
