Coolant Distribution Unit (CDU)
1MW 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.
1 MW Capacity
N+1 pumps, drives and filters
Extra large filter bodies to maximise filtration area
Front access to control panel, VSDs, expansion tank 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.
- PGDX Display – 7” color touchscreen integrates with Airedale by Modine ACIS™ BMS, Cooling System Optimizer™ system control and sensors.
- Pumps (N+1) – Redundant circulated pumps premium efficiency (standard), super premium efficiency (option). Simultaneous or run/standby options.
- Stainless Pipework – Stainless 304 sch10 pipework. Complete stainless secondary lines, including pumps, to eliminate particle generation.
- Controller – Intuitive user and communication interface and protocols for BMS. Ability to network up to 8 CDUs. High voltage isolation cover to allow for safe access.
- Heat Exchanger (HX) – Compact HX for low approach temperature differential. HX is customizable to optimize for application requirement.
- Variable Speed Drives (N+1) – Integrated, redundant variable speed drives for precise fluid delivery performance.
- Pipework Connections – Top connections (standard), bottom connections (option). Plain, grooved, flanged, tri-clamp sanitary options. Isolation valves, flow and return.
- Filters – Keeps the coolant fluid free from contaminants, protecting the integrity of the cold plate and maintaining cooling performance. Standard filtration of 50μ (25μ option).
- Motorized Isolation Valves – In the event of a leak the CDU would trigger an emergency shutdown, immediately closing supply/return legs of the sever side.
