Coolant Distribution Unit (CDU)
400kW – 2MW+ Liquid-Liquid Heat Exchanger for Liquid Cooled & Hybrid Data Center Architectures
Engineered to accelerate digital transformation and meet the needs of next-generation CPUs and GPUs, Airedale by Modine’s coolant distribution unit (CDU) enables liquid cooling in high-density IT applications.
Up to 2MW+ Capacity
N+1 pumps, drives and filters
Extra large filter bodies to maximize filtration area
Front access to control panel, VSDs, expansion tanks and filters
Airedale by Modine’s coolant distribution units (CDUs) are designed for direct-to-chip and hybrid cooling environments, including rear door heat exchanger (RDHx) applications that facilitate simplistic, modular, efficient and performance-driven deployments.
Engineered to perform, resilient and reliable with in-built redundant pumps, filtration and intuitive system controls to support load fluctuations with precise coolant delivery.
Configuration flexibility with option to select standard model or work with us to develop custom configurations,
Modular and global design, with ability to apply and deliver wherever your projects are.
Seamless integration into in-rack server profiles or facility rooms, Airedale by Modine’s CDU can combine with your existing infrastructure to create a dynamic, end-to-end, future-proof thermal management system.
- VU™ Touch Screen HMI – 7” colour touchscreen provides a graphical representation of the
system process, unit status and diagnosed specific faults including leak detection - Pumps (N+1) – Redundant circulated pumps premium efficiency (standard), super premium efficiency (option). Simultaneous or run/standby options
- Stainless Pipework – Stainless 304 SCH10 pipework, with Stainless 316 SCH10 selectable as an option. Complete stainless secondary lines, including pumps, to eliminate particle generation
- Controller & Control Panel – Intuitive user interface. Controller is responsible for ensuring precise control and managing uptime. Able to network up to 8 CDUs. Easy integration to any BMS including Airedale by Modine’s ACIS™ and Cooling System Optimizer™
- Plate Heat Exchanger (PHX) – Compact PHX customizable to optimize for application. Stainless steel/copper brazed PHX (standard). Fusion bonded stainless steel PHX optional
- Variable Speed Drives (N+1) – Integrated, redundant variable speed drives for precise fluid delivery performance
- Pipework Connections – Top connections (standard), bottom connections (option). Hygienic flanged and grooved options. Isolation valves for supply and return
- Filters – Keeps the coolant fluid free from contaminants, protecting the integrity of the cold plate and maintaining cooling performance. Standard filtration of 25μ (50μ option)
- Motorized Isolation Valves – Optional motorized isolation valves can be configured to isolate the CDU from the servers upon remote authorization by the plant operator
- Active Harmonic Filter (AHF) – Active harmonic filter integrated to compensate for unwanted harmonics. The AHF improves the system efficiency while reducing harmonic pollution. The AHF device is in compliance with IEEE 519 standard
