Outdoor heat rejection
How it is used
Connect the dry cooling unit to the facility side of the CDU. Available cooling capacity depends on outdoor air and required liquid temperature.
Selection checkpoint
Check summer ambient, winter freeze protection, sound limits and maintenance access.
Illustrative architecture, not a customer installation or an installation drawing.

Engineering fit
For primary-side heat rejection for 600 kW liquid-cooled halls, replacing cooling towers and chillers. Delivers 35 °C liquid at 30 °C inlet air as the primary-side source for in-row / in-rack liquid-to-liquid CDUs; most of the year runs on free cooling alone, with no chiller and no make-up water. Well suited to northern and arid regions.
- Primary-side heat rejection for 600 kW AI halls without cooling towers or make-up water
- Year-round free cooling in northern and arid climates
- Outdoor heat-rejection module for containerised / prefabricated liquid-cooled data centres
- Turnkey primary side with pump skids and in-row CDUs

Frequently asked questions
Dry cooler vs. cooling tower?
A dry cooler is a closed air-cooled exchanger: the coolant never touches air, does not evaporate and needs no make-up water or water treatment. A cooling tower cools lower by evaporation but consumes water. Liquid-cooled halls accept 35–45 °C primary water, so a dry cooler is usually sufficient.
Under what conditions is the 600 kW rating valid?
30 °C inlet air, liquid 35 °C / 40 °C, PG40. Capacity derates at higher ambient temperatures; extra air flow or adiabatic pre-cooling can compensate.
Why PG40?
Confirm coolant concentration against the site minimum temperature, the coolant supplier’s freeze-protection data and the project’s shutdown strategy. Operating ambient limits do not establish freeze protection for stagnant coolant.
Noise and footprint?
Unit size 6600 × 2280 × 2535 mm; variable-speed fans slow down at night and at part load. Sound levels and foundation requirements are given in the installation manual.
How does it connect to the CDUs?
Dry-cooler outlet feeds the primary side of in-row / in-rack liquid-to-liquid CDUs, whose plate heat exchangers isolate the secondary loop; use the built-in pumps or a separate TC-IPS pump skid.
Lead time?
Standard units ship in 8–10 weeks after factory pressure, leak, fan and pump switchover tests.
