High Performance Low Voltage LWW Liquid Cooling Unit for Transformers & PCBs

Low Voltage LWW Liquid Cooling Unit | Water-to-Water Liquid Cooling Solutions

Our Low Voltage LWW Liquid Cooling Unit is designed for power electronics, VFD systems, industrial equipment, energy storage systems, and thermal management applications requiring stable and efficient liquid cooling performance.

The system adopts a water-to-water heat exchange design, using ethylene glycol solution on the hot side and raw water on the cold side. It is especially suitable for applications where a chilled water source is available on site, such as VFD (Variable Frequency Drive) and power supply cooling systems.

Multiple structural configurations are available, including frame type, cabinet type, portable type, and wall-mounted type. Intelligent control systems and HMI monitoring interfaces can also be configured according to project requirements.


Key Features

  • Water-to-water heat exchange cooling technology
  • Ethylene glycol solution on the hot side
  • Raw water cooling on the cold side
  • Suitable for sites with chilled water sources
  • Multiple installation structures available
  • Intelligent control and monitoring options
  • Stable and energy-efficient operation
  • Industrial-grade reliable design

Working Principle

The system adopts:

  • Hot Side: Ethylene glycol solution circulation
  • Cold Side: Raw water circulation

The integrated water-water heat exchanger efficiently transfers heat from the coolant loop to the chilled/raw water system, ensuring reliable thermal management for high-power equipment.
