Indirect Evaporative and Liquid Cooling
Our products help data center cooling providers optimize server cooling by reducing fan power and chiller energy use. By enabling higher cooling water temperatures and eliminating outdoor contaminants, they lower operating costs while increasing cooling capacity, reliability, and system efficiency—unlike less-efficient fin-coil-based alternatives.

Benefits of Air or Liquid Cooling in Data Centers
Maintaining the correct temperature and humidity is critical for reliable data center operation. Excessive heat or moisture can lead to condensation, equipment damage, and costly downtime. To prevent this, data centers rely on efficient, proven cooling technologies that use either air or liquid as the heat-transfer medium.
Indirect air cooling is a highly effective method that uses outdoor air as a heat sink without allowing it to enter the server room. By integrating an air‑to‑air heat exchanger, heat is transferred between separate indoor and outdoor airflows, preventing contamination from dust, pollutants, and humidity.
For higher power densities or space‑constrained environments, air‑to‑liquid cooling provides a highly efficient alternative. By transferring heat directly from the air to a liquid circuit, air‑to‑liquid heat exchangers enable precise temperature control and high heat dissipation, making them ideal for demanding data center applications.
In cooler climates, dry cooling with air‑to‑air heat exchangers is often sufficient and requires no water. In warmer or drier regions, performance can be enhanced with indirect evaporative cooling (IEC), where spraying water on the ambient‑air side of the heat exchanger reduces air temperature through evaporation.
Both indirect air and liquid‑based cooling systems require heat exchangers that combine high efficiency, low pressure drop, strong corrosion protection, and reliable water‑tightness.
With more than a decade of experience in thermal management, Heatex delivers reliable and efficient heat exchanger solutions tailored to modern data center cooling requirements.
Our portfolio supports both air‑based and liquid‑based cooling architectures, enabling scalable solutions for today’s and tomorrow’s power densities.
- Air‑to‑Air Heat Exchangers offer a robust and cost‑effective solution for indirect air and evaporative cooling systems. With low maintenance requirements and proven performance, they are ideal for data centers with moderate heat loads where energy efficiency and operational simplicity are key.
- For higher rack densities and more demanding thermal conditions, Air‑to‑Liquid Heat Exchangers provide superior heat dissipation and precise temperature control. By efficiently transferring heat to a liquid circuit, they support stable operation in high‑power applications and enable compact data center designs.
To support optimal system design, Heatex Select, our product selection software, allows accurate performance calculations under real operating conditions. This ensures the right cooling solution is selected for each application, delivering maximum efficiency, reliability, and long‑term performance.
