Koolance VLR-600 Liquid Cooler, 600W – Black

With a massive 600W cooling capacity (2047 BTU/hr), the Koolance VLR-600 is a self-contained liquid cooling system engineered for extreme thermal loads. It integrates a powerful PMP-300 pump, a 1.5-liter reservoir, and a rotary compressor running on R-134a refrigerant, all housed in a rugged steel chassis. The front-panel digital LED display and buttons provide precise temperature set point control from 5°C to 40°C, while the built-in flow sensor and temperature alarms ensure safe operation. Standard G 1/4 BSPP fittings make it compatible with a wide range of liquid cooling components.

Overview

The VLR-600 is a turnkey solution for high-performance PCs, industrial equipment, or any application requiring reliable, high-capacity cooling. It operates on 100-240 VAC (50/60 Hz) and consumes up to 300W, delivering consistent thermal management without the complexity of a custom loop. The black steel enclosure is built for durability, and the system is pre-charged with 120g of R-134a refrigerant.
