Overview

A professional ambient liquid cooling system delivering approximately 4900 W capacity for high thermal loads in servers, workstations, and lab environments.

Performance and Thermal Capacity

The system provides roughly 4900 W of cooling at a 25 °C liquid-to-ambient temperature difference. A large copper and brass radiator paired with eight 120 mm fans handles extreme heat loads from servers, HPC workstations, and research equipment.

Monitoring and Control

A front-mounted OLED panel displays real-time coolant flow, temperature, pump speed, and fan speeds. USB connectivity enables software control, data logging, and configurable audio alarms or relay triggers based on thermal or flow thresholds.

Build and Integration

The unit fits a standard 19-inch 3U rack form factor and operates horizontally or vertically. It includes a 2.5-liter reservoir, standardized 3/8-inch NPT fittings, a rotatable display, and rack-mount ears. Power input accepts 100–240 VAC at 50/60 Hz with a noise range of 42–71 dB.
