LIQUID COOLING
FOR BATTERY ENERGY
STORAGE SYSTEMS
(BESS)

Protect your batteries. Maximize Uptime.

In battery energy storage systems, effective cooling is critical—it directly impacts performance, lifespan, and operational safety. Lithium-ion batteries are especially sensitive to temperature, performing best around 68°F; a rise of just 20°F can reduce their lifespan by 20%, and at 113°F, that lifespan can be cut in half. Pfannenberg brings over 70 years of thermal management expertise and a deep understanding of energy storage applications to every solution we design. Whether you’re powering an off-grid system or managing a compact, high-density BESS installation, our cooling technologies are built to maintain ideal battery temperatures and ensure efficient, reliable operation in any environment.
