Cooltechx manufactures liquid cooling units and air conditioners for battery energy storage, from C&I cabinets to utility-scale BESS containers. Our liquid cooling units can be configured to match your cooling load, installation space and coolant connections. Our BESS air conditioners use an upper side outlet that connects to the cabinet’s top air duct.

For containerized battery systems
Liquid-loop cooling for containerized BESS projects with defined coolant and piping interfaces.
For commercial & industrial battery cabinets
Compact liquid-cooling equipment for commercial and industrial battery cabinets.
For battery cabinets and containers
Air conditioning for battery cabinets and containers designed around internal airflow.
Bring the cooling equipment into your system design, from the required cooling duty to the cabinet connections.
Configure cooling around the battery heat load, site temperature and operating conditions.
Coordinate the mounting format, available space and air or liquid connections with your cabinet or container layout.
Define the electrical supply, control interfaces and communication requirements for integration with your equipment.
| Selection factor | Air cooling | Liquid cooling |
|---|---|---|
| Cooling Method | Moves conditioned air through the battery enclosure. | Circulates specified coolant through battery-side cooling interfaces. |
| Temperature Management | Depends on air distribution, enclosure design and the operating heat load. | Depends on coolant conditions, flow distribution and the battery-side heat-transfer design. |
| System Integration | Check air volume, ducts, return paths, mounting and enclosure sealing. | Check coolant type, supply/return temperatures, flow, pressure drop and piping connections. |
| Maintenance Considerations | Plan access to filters, fans, coils and air paths as applicable. | Plan coolant checks, leak inspection and access to pumps, valves, filters and connections. |
| Typical Applications | Battery cabinets or containers engineered for an air-based thermal design. | Battery cabinets or containers engineered with a compatible liquid-cooling loop. |
Both approaches must match the battery-system design and project operating conditions. Read the detailed air vs. liquid cooling guide →
20 kW liquid-cooling equipment for a 2 MWh BESS, with HVAC and piping integration.
7.5 kW air-conditioning equipment for a 2 MWh containerized battery system.
Technical answers before you specify a cooling system.
Start with the thermal architecture specified by the battery and enclosure designer. Check whether the design uses conditioned airflow or a battery-side coolant loop, then verify heat load, site conditions and integration requirements.
A BESS chiller removes heat from a specified liquid loop. A battery cabinet air conditioner conditions enclosure air. Their interfaces and ratings differ; equal nominal kW labels do not make them interchangeable.
Choose a single-system cooling product or a PACK + PCS dual-system product according to the integrator’s system design. The PACK + PCS product serves the cooling requirements of both loads.
Custom BESS cooling configurations can be reviewed against installation space, electrical supply, cooling interfaces, controls and site conditions. For OEM projects, share your drawings and technical requirements so our engineering team can confirm the available configuration and supply scope.
