Indirect Dry or Evaporative Cooling
Thermal Management is a key factor in the cost and operation of data centers. Air-to-air heat exchangers are used both for indirect dry and evaporative cooling solutions to remove excess heat from the data center air in a closed loop system.
Indirect Cooling in Data Centers
Indirect cooling methods have the benefit of not contaminating the inside air with outdoor air pollutants and humidity. A heat exchanger keeps both airstreams separated while transferring the heat from the inside to the outside of the data center building. Consequently, the ambient and indoor air never mix.
Usually, dry cooling is sufficient if the data center is located in a consistently low-temperature area, meaning no water is involved. However, by spraying water on the ambient air side of the heat exchanger, an evaporative effect is achieved, resulting in a lower indoor air temperature. This method is called indirect evaporative cooling (IEC).
Ideally suited for warm, dry climates, IEC provides excellent cooling potential with low operational- and first-cost. Ambient temperature reductions of 6-8 °C (10-15 °F) are typical in summer conditions. IEC provides up to 28% in energy savings compared to conventional free cooling and 52% to air-cooled Free Cooling alternatives.
Evaporative cooling requires a plate heat exchanger that balances high efficiency with low pressure drop, offers solid corrosion protection, and reliable water tightness. Heatex cross-flow heat exchangers meet all these requirements while providing outstanding cooling capacity.
Our cross-flow heat exchangers, especially with evaporative cooling technology, provide an efficient, low-cost, and environmentally friendly alternative to traditional cooling methods.
IEC Optimized Cross Flow Heat Exchangers
Maximum Energy Efficiency
Achieve the perfect balance of energy efficiency and pressure drop by choosing between two unique plate patterns and numerous plate distances. All plates are made of high-grade aluminum plates with turbulence-enhancing patterns.
Corrosion Protection & Water Tightness
Single or multilayered epoxy-coated plates, zinc-magnesium-coated steel end plates, aluminum profiles, and lacquered plate edges assure complete corrosion protection for the expected product lifetime (>15 years). Folded edges with AquaSeal sealings together with rigorous testing secure water tightness.
Cost-Effectiveness
Lower operating costs than refrigerant-based cooling methods.
Local production in Europe and China promotes on-time delivery and cost control.
