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
Customizable to suit site specific operational demands
Active harmonic filtration
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.
Designed to deliver resilient and precise cooling, the Airedale by Modine CDU features stainless steel pipework, in-built redundant pumps, active harmonic filtration, and intelligent controls that adapt to load fluctuations. It supports networking of up to eight units, offering a scalable solution for growing infrastructure needs.
A dedicated maintenance mode enables servicing of filters and pumps without disrupting operation, provided all safety protocols are followed, ensuring uptime and operational continuity.
Optimized for space efficiency, serviceability, and performance, the system is available in three standard footprints, with scalable capacities ranging from 400kW to 2MW. Flexible installation options allow placement within server rows, at the facility perimeter, outside the white space, or in the plant room, whether on a slab or raised floor.
Seamlessly integrating into in-rack server configurations or facility rooms, it works effortlessly with your existing infrastructure to deliver a dynamic, end-to-end thermal management solution. Designed with future scalability in mind, it ensures your cooling strategy remains robust and adaptable as your needs evolve.
With a modular design built for global application, Airedale by Modine’s CDU is ready to support your projects, wherever they are.
For large-scale deployments, we offer custom-engineered solutions tailored to your specific requirements.
