Koolance ALR-4600A Liquid Cooling System

If your hardware is running under continuous load, you need a cooling solution that won’t let you down. The Koolance ALR-4600A is a powerful ambient liquid cooling system designed for professional applications and high heat dissipation – engineered for maximum stability and precise control.

• Up to 4500 W cooling capacity for servers, workstations, and industrial setups.
• Large radiator with 8×120 mm fans for efficient heat dissipation.
• 10-step adjustable pump with up to 13 L/min flow rate.
• OLED display with real-time data on temperature, flow, and fan speeds.
• 19″ rack mounting as well as horizontal or vertical operation possible.

Koolance ALR-4600A – Industrial Liquid Cooling with 4500 W Capacity

The ALR-4600A is a powerful ambient liquid cooler for external heat dissipation. With a cooling capacity of up to 4500 watts at a 25 °C temperature differential, the system is suitable for demanding environments such as data centres, laboratory applications, or high-performance workstations. The large aluminium radiator is supported by eight 120 mm fans to reliably handle even high thermal loads.

Precise Control & Comprehensive Monitoring

The integrated OLED display lets you keep an eye on all relevant operating values: temperature, flow, pump, and fan speeds. The pump can be manually adjusted in ten stages and achieves a maximum flow of approximately 13 litres per minute. Additionally, acoustic alarm functions are available to respond immediately to critical conditions. Via USB interface, you can connect the system to a PC to read out or log operating data.

Robust Construction for Professional Integration

The system features an integrated 2.5-litre reservoir and standardised 3/8-inch NPT fittings for flexible integration into existing cooling loops. Thanks to 19-inch rack compatibility and the option for horizontal or vertical positioning, the ALR-4600A can be optimally integrated into professional infrastructures. Power supply is via 100–240 V AC, enabling worldwide use without any issues.
