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 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 which results in a lower temperature of the indoor air. 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% compared to air-cooled Free Cooling alternatives.
Evaporative cooling requires a particular type of plate heat exchanger that balances high efficiency with low-pressure drop and offers solid corrosion protection along with 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.
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 together with powder-coated frameworks and lacquered plate edges assure complete corrosion protection for the full 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.
*To make sure the exchanger is completely watertight, testing is required. **Local differences between our production sites might occur.
Model H is Heatex’ original cross-flow plate heat exchanger. It comes with either a single or multilayer of epoxy for upgraded corrosion resistance. Extra high plate distances minimize pressure drop.
