Latest company news about DCL Electric Actuators Enable Precision Control in Generator Liquid Cooling Systems
Technical Background

As power density of generator sets continues to increase, liquid cooling systems have become critical solutions for large generator heat dissipation. DCL electric actuators play a key role in valve control for generator liquid cooling systems with their precise flow control, high-temperature resistance, and explosion-proof certifications, ensuring generators operate safely within optimal temperature ranges.

Technical Advantages
  1. High-Temperature Tolerance
    Utilizing special sealing materials and heat dissipation design, capable of continuous operation in ambient temperatures from -40°C to 120°C, allowing direct installation in high-temperature areas of generators.

  2. Precise Flow Regulation
    Equipped with high-resolution encoders (up to 0.1% adjustment accuracy) to dynamically regulate coolant flow, maintaining generator winding temperature within ±1°C.

  3. Explosion-Proof Certification
    Certified by ATEX and IECEx (Ex d IIC T4), suitable for hazardous environments such as hydrogen-cooled generators.

  4. Vibration Resistance Design
    Mechanical structure meets 10-2000Hz vibration test standards, ensuring long-term stable operation in high-vibration generator environments.

Typical Applications
  • Main Cooling Circuit Control Valves: Precise coolant flow regulation based on load changes

  • Backup Cooling System Switching Valves: Seamless transition between primary and backup cooling systems

  • Hydrogen Cooler Control: Regulating coolant supply to hydrogen coolers

  • Emergency Shutdown Valves: Rapid coolant cutoff during overheating events
