EXC-450 Portable 450W Recirculating Liquid Chiller, 24VDC (Rev.2.0)
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).
Coolant flow rate, temperature, and reservoir level are monitored, and a USB port allows control and logging of most features using the Koolance System Monitor application. A 0-5V differential voltage output is also provided for industrial process monitoring.
- Cooling capacity: 450W (1535BTU/hr) @ 25°C liquid/ambient
- Temperature options: liquid set-point, external thermocouple set-point, liquid and ambient delta-T, external thermocouple and ambient delta-T; toggle °C/°F
- Pump: 10 manual levels, up to 8.2LPM (2.2GPM)
- 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 and relay trigger (NO or NC) based on: temperature, flow rate, coolant level, pump RPM, and condenser fan RPM
- Refrigerant: R-134a
- Power input: 24VDC, 250W
- 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
- NPT 1/4in threads on back for fittings
NOTE: Requires 24VDC input power. Koolance offers a separate power supply for AC wall outlet sources. Keep unit upright at all times, and for at least 24 hours before applying power to ensure sufficient oil reaches the compressor.

Liquid Coolants
Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth. Additionally, do not use aluminum with bare (unplated) copper or bare (unplated) brass in the same system. Do not use silver with nickel in the same system.
