BESS Air Conditioner (7.5kW–30.0kW) | JXCooling

JXCooling BESS air conditioners are engineered for thermal management of Battery Energy Storage System (BESS) containers and energy storage rooms. Designed for continuous-duty operation, the unit provides cooling, heating, and dehumidification to maintain a stable environment for batteries, PCS, EMS/BMS, and power electronics—helping improve safety, reliability, and lifecycle performance.

With top air discharge airflow design, the system supports efficient air distribution in container spaces, reduces hotspots, and enhances temperature uniformity across battery racks. Built for harsh site conditions, JXCooling BESS HVAC solutions feature IP55 protection, RS485 communication, and high-capacity performance from 7.5kW to 30.0kW.

Key Benefits

• Cooling + Heating + Dehumidification in one unit for year-round container climate control

• Top air discharge design for better air distribution and reduced thermal stratification

• High-capacity range: 7.5kW / 10kW / 12.5kW / 15kW / 20kW / 25kW / 30kW (selection by heat load)

• IP55 protection for reliable outdoor/container-side installation

• RS485 monitoring for remote status, alarms, and integration with BESS supervisory systems

• Stable operation to help prevent overheating, condensation, and humidity-related failures

How It Works in a BESS Container

BESS environments require both temperature control and moisture management:

• Cooling mode removes heat generated by batteries, PCS, inverters, and busbars

• Heating mode maintains minimum operating temperature in cold seasons to protect performance

• Dehumidification controls moisture to reduce condensation risk and corrosion, improving insulation reliability

Selection Guide (Fast Sizing Inputs)

To recommend the right capacity and configuration, please share:

1. Container size and layout (battery racks arrangement)

2. Total heat load (kW) from batteries + PCS + auxiliary equipment

3. Ambient temperature range (summer peak and winter low)

4. Target internal temperature/humidity requirement

5. Installation position and airflow direction preference

6. Monitoring requirements (RS485 address/protocol details)

Tip: Choose capacity with margin for peak charge/discharge cycles and high ambient temperature conditions.

Installation Notes

• Ensure sufficient clearance for air inlet/outlet to avoid hot-air recirculation

• Use proper condensate drainage and waterproof cable routing

• Seal mounting cut-outs to maintain container protection level

• For best temperature uniformity, keep airflow unobstructed along the aisle and rack fronts

Monitoring & Integration

With RS485, the air conditioner can be connected to BESS EMS/BMS or site SCADA to support:

• Remote ON/OFF and status monitoring

• Alarm reporting and fault codes

• Temperature/humidity management strategy coordination
