Koolance ALR-4600C Liquid Cooling System

If you work with high thermal loads, the Koolance ALR-4600C is a professional ambient liquid cooling system that combines massive cooling power, flexible mounting, and precise monitoring – perfect for demanding servers, workstations, or laboratory cooling circuits.

• Approximately 4900 W cooling capacity at 25 °C liquid-to-ambient delta for high thermal loads.
• Large copper/brass radiator with 8×120 mm fans for efficient heat dissipation.
• OLED display for real-time monitoring of flow, temperature, and fan speeds.
• USB monitoring and logging with compatible software.
• Rack-mountable (19-inch, 3U) and mountable horizontally or vertically.

Koolance ALR-4600C – High-Performance Ambient Liquid Cooler

The ALR-4600C is an industrial ambient liquid cooling system with an outstanding cooling capacity of around 4900 W at a 25 °C liquid-to-ambient delta – perfectly suited for applications with very high heat dissipation such as servers, HPC workstations, or research facilities. The system uses a large copper/brass radiator with eight 120 mm fans to ensure efficient heat removal.

Intelligent Monitoring & Flexible Control

A front-facing OLED display shows real-time values such as coolant flow, temperature, pump, and fan speeds. You can connect the system via the USB port to the Koolance System Monitor software to control functions and log data. Audio alarms and relay triggers can be configured based on temperature or flow values.

Robust Design & Professional Integration

The ALR-4600C features a 2.5-litre reservoir, standardised 3/8-inch NPT fittings, and is housed in a 19-inch 3U rack form factor. It can be operated both horizontally and vertically – including rack mounting ears and a rotatable display for optimal readability. Power is supplied via 100–240 VAC, 50/60 Hz, and the device operates at a noise level of approximately 42–71 dB.
