High Voltage LWW Liquid Cooling Unit | High-Efficiency Water-to-Water Liquid Cooling Solutions

Our High Voltage LWW Liquid Cooling Unit is designed for high-voltage power electronics, VFD systems, industrial power equipment, and advanced thermal management applications requiring reliable and efficient liquid cooling performance.

The system adopts a water-to-water heat exchange design with an integrated plate heat exchanger, using ethylene glycol solution on the hot side and raw water on the cold side. It is especially suitable for environments where chilled water sources are available on site, such as VFD and power supply applications.

Equipped with a complete high-voltage liquid cooling system including online deionization, automatic water replenishment, fault diagnosis, and redundancy protection functions, the unit ensures stable and safe long-term operation.
