Application Focus: Data Center UPS Cooling
Uninterruptible Power Supplies (UPS) are the backbone of data center reliability, providing continuous power during outages to protect critical servers, storage systems, and networking equipment. The OWP-BL43-200 Electric Coolant Pump plays a vital role in UPS thermal management by:
- Maintaining Optimal Operating Temperatures: Delivers consistent, high-volume coolant circulation (up to 4800L/H) to dissipate heat generated by UPS inverters, batteries, and power modules—preventing overheating and ensuring stable performance.
- Supporting Critical Loads: With a maximum lift head of 20M and wide voltage range (18-32VDC), the pump adapts to diverse UPS system configurations, including large-scale modular UPS setups in enterprise data centers.
- Ensuring 24/7 Reliability: IP68 protection, dry running resistance, and automotive-grade components guarantee uninterrupted operation in mission-critical environments where downtime is costly.
- Reducing Energy Consumption: High motor efficiency (3-5% above industry standards) and low power draw align with data center sustainability goals, cutting energy costs while maintaining cooling performance.
Whether deployed in colocation facilities, cloud data centers, or enterprise server rooms, the OWP-BL43-200 ensures UPS systems operate at peak efficiency—protecting valuable equipment and ensuring business continuity.
