Key Advantages of Stulz CyberCool CDU
Optimization for NVIDIA AI
The solution is specifically designed to handle extreme thermal loads from modern high-density rack GPU accelerators.
100% Free Cooling
The solution allows for year-round use of energy-efficient warm-water cooling technology in accordance with ASHRAE W32 - W+ standards.
Complete Loop Isolation
Hermetic separation of FWS and TCS loops completely eliminates risks of cross-contamination and fluid leakage inside IT racks.
Technological Architecture Features
Chip and Platform Cooling
The CDU module acts as the central element for both direct on-board component cooling (Direct-to-Chip) and immersion cooling tanks.
Maximum Pump Efficiency
Variable-speed pumps automatically adapt performance to low loads, eliminating the need for bypass lines.
Impeccable Loop Cleanliness
Stainless steel piping and integrated mechanical filters guarantee that the rack cooling loop (TCS) contamination level does not exceed 50 μm.

Detailed Overview of Module Characteristics
CyberCool CDU includes premium components: plate heat exchangers, intelligent water valves, and stainless steel hydraulics. Joint expertise with NVIDIA allowed for the adaptation of CDU controller algorithms to the dynamic heat dissipation spikes characteristic of training Large Language Models (LLMs) and running neural networks on GPU clusters.
Stulz's proprietary automation provides precise regulation of pressure, flow, and differential temperatures. The system features an integrated condensation prevention function and supports remote monitoring of filters on both sides. For critical environments, factory options for full redundancy of power supplies, pumps, and controllers are available.
All components of the CyberCool CDU architecture are accessible to engineers from both the front and rear. Main nodes are connected using quick-connect couplings, while pumps and valves feature individual shut-off valves for easy replacement or filter cleaning without stopping the data center cooling system.
Frequently Asked Questions About Stulz Cooling Systems
Modern computing architectures for AI (e.g., NVIDIA DGX and similar platforms) have extremely high heat density per rack, which cannot be compensated for by traditional air conditioning. The CDU module from Stulz provides precision fluid distribution directly to the processors, eliminating the risks of thermal throttling.
