Dry cooler DC

Overview
Air‑to‑liquid dry cooler designed for high‑density liquid cooling systems in AI and HPC data centers. The EXTRCOOL DC‑Series rejects waste heat from CDU loops and liquid cooling racks, supporting NVIDIA GB200/GB300 GPU liquid cooling and rated variants from 150 kW up to 2000 kW for continuous 24/7 operation.

Core Technical Advantages

• High‑efficiency heat rejection: Large‑area finned‑tube heat exchanger combined with high static pressure fans maximizes air‑side heat transfer for closed liquid loops without chilled‑water systems.
• Containerized outdoor design: ISO‑compliant container enclosures, corrosion‑resistant coatings and vibration‑damping structure for reliable outdoor deployment.
• Modular, scalable architecture: Multi‑fan parallel configuration enables capacity matching from 150 kW modules up to MW‑scale installations.
• Low‑noise, energy‑adaptive operation: Variable‑speed EC fans with PID control adjust airflow by supply/return temperature to lower power draw and data center PUE.
• Plug‑and‑play integration: Standard flange connections and pre‑tested piping simplify integration with CDU, cold plates and manifolds for rapid deployment or retrofits.

Frequently Asked Questions (selected)

• What does a dry cooler do in a liquid cooling system? It rejects heat from the liquid loop to ambient air, acting as the CDU heat rejection unit and eliminating the need for chilled water.
• Why choose a dry cooler over a cooling tower? Dry coolers operate without water evaporation, avoiding water consumption, scaling and Legionella risks while reducing maintenance.
• Is the EXTRCOOL dry cooler compatible with common CDU systems? Yes — standard liquid loop pressures and temperatures are supported and flange connections can be customized to match most commercial CDUs.
