Engineered for demanding industrial environments, the OWP-BL400H-D2-21 stainless steel coolant pump delivers exceptional performance, durability, and precision for distributed generation (DG) and combined heat and power (CHP) applications. With IP68 protection, 20,000+ hours of service life, and multi-layer safety features, this pump ensures stable coolant circulation to optimize energy efficiency and equipment reliability.

1. Superior Durability: Stainless steel wetted components resist corrosion and wear, while IP68 protection enables reliable operation in harsh, humid, or dusty environments—critical for outdoor DG installations and industrial CHP facilities.
2. High Efficiency & Precision: 400W rated power delivers 3000L/h flow rate and 20m head, ensuring rapid heat dissipation for generators, heat exchangers, and power electronics. PWM speed control allows real-time flow adjustment to match dynamic load demands.
3. Comprehensive Safety Features: Integrated reverse polarity, no-load, locked-rotor, and voltage protection prevents equipment damage, minimizing downtime and maintenance costs. Error feedback via high/low level signals enables proactive troubleshooting.
4. Easy Installation & Maintenance: Flange quick-connect design simplifies assembly and disassembly, while airtight construction (0.35Mpa test pressure, 8mL/min leakage) ensures long-term sealing performance.
5. Wide Operating Range: -40℃ to 85℃ temperature tolerance adapts to extreme climate conditions, from cold outdoor DG sites to high-temperature CHP heat recovery systems.

The OWP-BL400H-D2-21 is specifically designed to meet the thermal management needs of distributed generation and CHP systems, where efficient heat transfer directly impacts energy output and system longevity.

In distributed generation (e.g., solar PV plants, wind turbines, small-scale gas generators), the pump circulates coolant through inverters, transformers, and generator windings, preventing overheating and ensuring consistent power production. Its wide voltage range (DC18V~32V) and stable performance under fluctuating loads make it ideal for off-grid and hybrid DG systems, while IP68 protection withstands exposure to rain, dust, and temperature extremes.

For combined heat and power (CHP) applications—including industrial cogeneration, commercial building energy systems, and municipal heating networks—the pump plays a critical role in heat recovery and distribution. It efficiently circulates coolant between power generation units and heat exchangers, maximizing the utilization of waste heat for space heating, hot water supply, or industrial processes. The pump’s long service life (>20,000 hours) and low noise operation (dB(A)) ensure reliable, quiet performance in continuous-duty CHP environments, while multi-layer safety protections safeguard against system failures that could disrupt energy and heat supply.

With its robust construction, precise control, and tailored design for DG and CHP systems, the OWP-BL400H-D2-21 stainless steel coolant pump is the trusted choice for optimizing thermal management, reducing energy consumption, and enhancing the reliability of distributed energy systems.
