Application: Data Center UPS Cooling
Uninterruptible Power Supplies (UPS) are the backbone of data center reliability, providing instant backup power during outages to protect critical servers, storage systems, and networking equipment. However, UPS systems generate significant heat during operation—especially under high load—which can degrade components and compromise performance over time. The OWP-BL43-440C Electric Coolant Pump addresses this challenge by delivering efficient, consistent cooling to UPS batteries, inverters, and rectifiers.
With a wide operating temperature range (-40℃ to +85℃ for the cooling medium) and robust IP68 protection, the pump performs reliably in harsh data center environments, including high-humidity and extreme-temperature conditions. Its high flow rate (up to 4600L/H) and maximum lift head (23M) ensure rapid heat dissipation, preventing overheating and maintaining UPS efficiency. The pump’s PWM speed regulation allows for energy-saving operation, aligning with data centers’ sustainability goals, while its comprehensive protection features minimize the risk of pump failure—critical for avoiding UPS downtime.
Whether deployed in large-scale data centers, colocation facilities, or enterprise server rooms, the OWP-BL43-440C Electric Coolant Pump is the trusted choice for UPS cooling, combining technical excellence, durability, and cost-effectiveness.
