CDUs, rear-door heat exchangers, direct-to-chip, chillers and leak detection. Size cooling to rack power density. Liquid cooling becomes necessary once GPU racks pass the limits of air.
passive rear-door · up to 40 kW/rack
From $7,400 / unit
Min order 2 units
active rear-door · up to 55 kW/rack
From $9,600 / unit

Size to rack power density, match CDU and loop capacity to real kW per rack, not nameplate ratings.
Confirm water temperatures, supply/return temps and approach decide whether DLC, RDHx or chillers fit.
Build in N+1 redundancy, redundant pumps and CDUs keep a hall running through maintenance.
Cooling follows compute, quote it with the GPUs it cools so capacity and rack count match.
Our engineers scope power, cooling and compute together. No payment, and quotes come back in about a business day.
