Hitema Cooling Distribution Unit (CDU) — Rack-Level Liquid Cooling, Fully Custom

The Hitema CDU delivers precision rack-level liquid cooling engineered for direct-to-chip and rear-door heat exchanger deployments. Every unit is 100% custom-built — no standard catalogue size is applied — ensuring thermal performance is matched exactly to the rack density and redundancy requirements of each project.

The CDU features a stainless steel plate heat exchanger with a heat exchange capacity of up to 663 kW, VFD-controlled pumps with adjustable flow, front-access service panels, and integrated leak detection. The secondary loop maintains precise temperature and ΔT control, ensuring stable thermal conditions across high-density AI and HPC racks. The modular, stackable architecture allows future rack density growth without increasing physical footprint.
