JXCooling BESS Cooling Solutions
Air Cooling System + Liquid Cooling System
JXCooling provides complete thermal management solutions for Battery Energy Storage Systems (BESS), helping maintain safe operating temperatures and controlled humidity for battery racks, PCS, and auxiliary electrical equipment. Stable thermal conditions reduce overheating risk, improve performance consistency, and support longer battery life—especially during high-power charge/discharge cycles and in harsh ambient climates.
Our BESS portfolio includes two main solution paths: Air Cooling Systems for container climate control and Liquid Cooling Systems for high-efficiency rack-level cooling.
1) Air Cooling System for BESS (Cooling + Heating + Dehumidification)
Overview
JXCooling BESS air cooling systems regulate the container air environment to keep batteries and power electronics within safe temperature and humidity ranges. This is a practical and widely used approach for containerized storage where airflow distribution and moisture control are critical.
Key Benefits
Cooling, heating, and dehumidification in one system for year-round operation
Supports stable container temperature and reduces condensation risk
Top air discharge design improves airflow distribution and reduces hotspots
Built for field deployment with IP55 protection (model-dependent)
Monitoring-ready integration via RS485 (standard on many configurations)
Typical Applications
Containerized BESS (20ft/40ft) with battery racks and PCS sections
Grid-side storage stations and C&I energy storage projects
Sites requiring humidity control and seasonal heating support

2) Liquid Cooling System for BESS (Rack-Level Thermal Management)
Overview
JXCooling liquid cooling systems deliver precise thermal control for liquid-cooled battery racks. Coolant circulates through cold plates or liquid channels to remove heat efficiently and maintain tight temperature uniformity—ideal for high-density racks and high C-rate operation.
Key Benefits
High heat transfer efficiency for high power cycling
Improved temperature uniformity (reduced hotspots and gradients)
Better scalability for high-density and high-capacity systems
Energy-saving control strategies (variable-speed pumps, optimized heat rejection)
Monitoring-ready integration for alarms and maintenance management
Typical Applications
Liquid-cooled battery racks in BESS containers
High-density or high C-rate storage projects
Hot climate deployments or sites with strict temperature control requirements

How to Choose (Quick Guide)
Choose Air Cooling when you need container-level climate control (temperature + humidity) and a cost-effective, widely adopted approach.
Choose Liquid Cooling when you require higher efficiency and tighter temperature uniformity, especially for high-density racks or aggressive cycling profiles.
Many advanced projects use hybrid strategies: liquid cooling for battery racks + air cooling or ventilation for auxiliary rooms/equipment.
