In Rack CDU | Compatible With All NVIDIA Server Models

In Rack CDU（Coolant Distribution Units）is suitable for AI, HPC, modular, and retrofit data center ,there are two standard power consumption products (65KW/130KW) to choose from. Equipped with dual power supplies, power supply 220v, input power 480w, a single CDU is equipped with 2 pumps, and supports cycle and automatic fault switching functions; local and remote system parameter settings, running status viewing, running time recording, alarm information query, and also It can automatically save settings and fault information and will not be lost when the power is turned off. When the power is turned off and then comes back, the CDU can start and run automatically.Furthermore, it is compatible with all NVIDIA server models.

Application in liquid cooling system

Rack-mounted CDU closely and intelligently connects the room-level cooling infrastructure with the server-level heat dissipation requirements. It is a key link in unleashing the potential of liquid cooling technology and addressing the heat dissipation challenges of modern high-density computing.

It has six major advantages in liquid cooling system：

1.Compatible with all NVIDIA server models.（B200/B300,GB200/GB300,H100/H200)

2.Up to 135kW Cooling Capacity in a Compact 4U Form Factor
3.Rack-Level Cooling Distribution for Lower PUE
4.N+1 Redundant Pumps & Dual Power for Maximum Availability
5.Factory-Integrated, Plug-and-Play Deployment (50% Faster Installation)
6.Comprehensive Intelligent Leak Detection & Multi-Layer Protection

FAQ
What is the In rack CDU and why is it important for modern data centers?

A In Rack CDU (Coolant Distribution Unit) is a liquid-cooling system installed at or near a server rack that regulates, pumps, and distributes coolant to IT equipment such as high-density servers, GPUs, or AI accelerators. It acts as the thermal interface between the facility’s cooling loop and the rack-level liquid-cooled hardware. Rack CDUs are important because they enable efficient heat removal at much higher power densities than air cooling, reduce overall energy consumption, improve temperature stability, and support next-generation workloads like AI and HPC while helping data centers lower operating costs and meet sustainability goals.

What are the benefits of using a Liquid cooling CDU for servers?

Answer: A Liquid cooling CDU delivers precise thermal control, higher rack density, lower PUE, and quieter operation. It enables higher performance per rack (supporting greater compute density), reduces chiller load, simplifies coolant management, and provides monitoring and safety features that protect servers — making it ideal for high-density and edge deployments.

How do I choose the right CDU in liquid cooling deployments?
Answer: When selecting a CDU in liquid cooling deployments, evaluate flow rate and pressure capacity, thermal capacity (kW per rack), compatibility with coolant type, monitoring/telemetry options , redundancy and serviceability, footprint, and compliance (materials, certifications). Match CDU specs to your server cold plates, rack power density, and site cooling infrastructure for reliable performance.
