The OWP-BL300H-A2-7 Electronic Coolant Pump is specifically designed to address the thermal management challenges of energy storage systems, including lithium-ion battery packs, flow batteries, and energy storage containers. As energy storage systems operate under varying load conditions and environmental stresses, maintaining optimal temperature is critical to battery performance, safety, and lifespan—and the OWP-BL300H-A2-7 delivers precisely that.

With its rated power of 300W±10% and flow rate of ≥2880L/H at 17.5m head, the pump efficiently circulates coolant throughout the system, rapidly dissipating heat generated during charging and discharging cycles. This prevents thermal runaway, a major risk in energy storage applications, and ensures battery cells operate within their optimal temperature range (-40℃ to 85℃, withstanding instantaneous temperatures up to 105℃). The closed impeller design enhances heat transfer efficiency, while the low noise level (≤65dB) makes it suitable for indoor and residential-adjacent energy storage installations.

The pump’s wide voltage compatibility (175VAC-275VAC) is particularly valuable for energy storage systems, which may experience voltage fluctuations from grid connections or renewable energy sources (solar/wind). Its IP68 protection class and resistance to high humidity (＜90%RH) enable reliable operation in outdoor or harsh industrial environments, where dust, moisture, and temperature extremes are common. With a service life exceeding 40000 hours, the OWP-BL300H-A2-7 minimizes maintenance requirements and replacement costs, ensuring long-term system stability and reducing total ownership expenses for energy storage operators.

Whether deployed in utility-scale energy storage plants, commercial rooftop systems, or residential battery storage setups, the OWP-BL300H-A2-7 Electronic Coolant Pump provides a robust, efficient, and durable thermal management solution. Its combination of key performance features—high flow rate, wide operating range, exceptional durability, and environmental resilience—makes it the ideal choice for optimizing energy storage system performance, safety, and longevity.
