At our core, we are committed to providing a flexible and tailored solution to meet your specific needs. Through a highly adaptable system of standardized components, we enable a wide range of configurations that can be customized to suit different operational requirements.

Liquid cooling solution with integrated Direct Chip Liquid Cooling (DCLC)

Energy efficiency & reliability

High Efficiency

  • Extremely low pPUE (~1.02 at full load) for optimal energy performance
  • Year-round Free Cooling possible depending on TCS water temperature specifications
  • Energy-efficient inverter components, including EC fans and inverter pumps, eliminating the need for liquid bypass
  • Slightly oversized pipes reduce pump power consumption, enhancing overall efficiency

 

High Reliability

  • Verified by third-party performance reports (noise, EMC, and pPUE) ensuring transparency and reliability
  • Optional redundant configuration of critical components (power supply, pumps, EC fans)
  • Redundant sensorics for key features
  • High-quality liquid maintained with sanitary-grade stainless steel pipes and a built-in filter on the TCS side preserving 50 μm water cleanliness
  • Optional 25 μm filter on the TCS side
  • Integrated anti-condensation function
  • Room neutral cooling: racks do not release heat into the IT room
  • Leak detection
