VLR-600 Refrigeration Liquid Chiller

Koolance's VLR-600 is a compressor-refrigerant recirculating liquid chiller rated at 600W, or 2047 BTU/hr (@25°C liquid & ambient). The cooling system can be mounted to a 19-inch equipment rack and is 3U in height.

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.

For added convenience during refilling and draining, Koolance QDT3 quick disconnects are located on the front. To utilize them, a QDT3-F10X13 quick disconnect, funnel, and short fill/drain tubing are included with VLR-600.
