ALR-4500 is Koolance's highest performing ambient liquid cooling system. It can be oriented in horizontal or vertical orientations, and is rack-mountable. This model contains a large eight x 120mm fan aluminum radiator, providing roughly 4300W 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: 4300W (14,672BTU/hr) with 25°C liquid-ambient delta @ 9LPM
• Temperature in °C/°F with set-point based on: liquid (-30 to 90°C), or one of two optional K-type thermocouples (-20 to 120°C)
• Pump: 10 manual levels, up to 10.5LPM (2.8GPM)
• 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 1/4in threads on back for fittings

The cooling system can be positioned in multiple ways. Feet are included for vertical tower or horizontal orientations, with fans facing up or down. The unit also fits within a 3U profile and includes rack mountable ears. The front display can be rotated for these positions by hand. NOTE: 3 x 700mL bottles of coolant are recommended for this system.

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.
