Koolance ALR-4600 Liquid Cooling System

ALR-4600 is a high performance ambient liquid cooling system. It can be operated in horizontal or vertical orientations, and is rack-mountable. This model contains a large eight x 120mm fan aluminum or copper radiator, providing roughly 4500W or 4900W of cooling with a 25°C ambient delta. 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.

• Cooling capacity Aluminum: 4500W (15,355BTU/hr) with 25°C liquid-ambient delta @ 12LPM
• Cooling capacity Copper: 4900W (16,719BTU/hr) with 25°C liquid-ambient delta @ 13LPM
• Temperature in °C/°F with set-point based on: liquid, or one of two optional K-type thermocouples
• Pump: 10 manual levels, up to 13LPM (3.4GPM)
• Select only values you want displayed on the front 2-line OLED display (fixed or rotating)
• Show coolant flow rate in LPM/GPM
• Show pump impeller speed in RPM
• Enable audio alarm based on: temperature, flow rate, and/or reservoir coolant level
• Enable relay trigger (NO or NC) based on: temperature, flow rate, and/or reservoir coolant level
• Power input: 110/220VAC, 50-60Hz
• Max power consumption: 220W
• Reservoir capacity: 2.5l (0.66gal)
• NPT 3/8in threads on back for fittings

The cooling system can be positioned in multiple ways. Bracket feet are included for vertical operation, and the unit should be rack mounted when horizontal. The unit fits in a 19-inch, 3U rack profile. The front display can be rotated for these positions by hand. NOTE: 3 x 700mL bottles of coolant are recommended for this system.
