BATTERY ENERGY STORAGE

Battery Energy Storage Cooling Systems

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.

Air Cooling vs. Liquid Cooling for BESS

Selection factorAir coolingLiquid cooling
Cooling MethodMoves conditioned air through the battery enclosure.Circulates specified coolant through battery-side cooling interfaces.
Temperature ManagementDepends on air distribution, enclosure design and the operating heat load.Depends on coolant conditions, flow distribution and the battery-side heat-transfer design.
System IntegrationCheck air volume, ducts, return paths, mounting and enclosure sealing.Check coolant type, supply/return temperatures, flow, pressure drop and piping connections.
Maintenance ConsiderationsPlan access to filters, fans, coils and air paths as applicable.Plan coolant checks, leak inspection and access to pumps, valves, filters and connections.
Typical ApplicationsBattery 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 →

BESS Cooling FAQs

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.
