Liquid-to-Air Coolant Distribution Units (CDU)
A facility-wide water loop is a major capital decision— and not one you should have to make just to cool one high-density rack or row. Liquid-to-air (L2A) CDUs reject heat straight to the air, delivering liquid cooling from 6 kW at the rack to 240 kW across a row, without facility-wide water infrastructure
6 kW – 240 kW Standard Capacity Range
In-Rack & In-Row Configurations
Built-In Pump, Fan & Power Redundancy
Scale cooling capacity to match your deployment
No Facility Water Loop Required
Rejects heat directly to the surrounding air rather than a facility chilled-water loop, removing the cooling towers, condenser-water pumps, and water treatment infrastructure a liquid-cooled facility retrofit would otherwise require.
Scalable From Rack to Row
Available in standard in-rack configurations from 6 to 24 kW and in-row configurations from 90 to 240 kW, letting cooling capacity scale with deployment size instead of forcing a single fixed architecture.
Redundant by Design
1+1 pump redundancy and, on in-row models, N+1 fan redundancy with dual power input keep cooling running through a single component fault, with online maintenance so service doesn't mean downtime.
Find the L2L CDU you need.
In Rack | L2A
Liquid cooling at the rack, no facility water loop — 6 to 24 kW for single-rack deployments that need to add density without infrastructure buildout.
In Row | L2L
Row-level liquid cooling without a facility water loop — 90 to 240 kW, scaling capacity to where density spreads across a row.
