Efficient Liquid Cooling solution for IT loads up to 100 kW per rack
Our solution, equipped with integrated Direct Chip Liquid Cooling (DCLC), is a standardized, row-style modular data center designed for high-density applications. It combines air and liquid cooling from a single source, ensuring optimal performance for IT loads up to 100 kW per rack.
Manufactured, fully tested, and ready for deployment, this modular data center offers customers peace of mind.
Liquid Cooling System Overview
Climate. Customized.
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.
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
Fast and easy deployment
The integrated Liquid Cooling system is designed for rapid deployment, with setup completed in one day. It includes pre-installed piping for the Technical Cooling System (TCS) and Facility Water System (FWS), requiring only a quick connection to the pump and dry cooler. No additional components or chiller are necessary, making this a streamlined and efficient solution for your cooling needs.
Components
- Control system with integrated monitoring system
- CyberCool CMU Coolant distribution unit (CDU)
- Technical Cooling System (TCS)
- Pre-installed piping for Technical Cooling System (TCS) and Facility Water System (FWS)
- DCLC racks with manifolds for 80 % Liquid Cooling
- Power Distribution Unit (PDU)
- CyberRack Active Rear Doors (air-cooled) for the remaining 20 % of the cooling requirement
Components: This all-in-one system was designed with all the essential components to deliver a comprehensive and reliable solution for your specific application needs.
Precise control for greater reliability
Thanks to its flexible and precise control, the integrated Liquid Cooling sytems ensures maximum reliability during continuous operation. In addition, to achieve the highest standards of reliability and usability, STULZ develops the controller in house, ensuring that software, hardware and liquid cooling units are perfectly harmonized.
Other advantages
