CDU capacity has moved rapidly from hundreds of kilowatts toward multi-megawatt modular plants. The market includes liquid-cooling specialists and broad infrastructure vendors.
Specialist suppliers
CoolIT, LiquidStack, Motivair, Accelsius, Chilldyne, and ZutaCore bring architecture-specific products. Their differentiation often sits in cold-plate integration, controls, pressure strategy, or phase-change design.
Infrastructure suppliers
Vertiv, Schneider Electric, nVent, STULZ, Rittal, Modine, and Delta can connect CDUs to broader rack, power, plant, and service portfolios.
Normalize the bids
Require net capacity at common supply and return temperatures, one-failure redundancy, total pump power, approach temperature, water pressure, fluid quality, controls points, certification, and footprint.
