Thermal Management is a key factor in the cost and operation of data centers. Heat exchangers are used both for indirect dry and evaporative cooling solutions to remove excess heat from the data center air.
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.
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 special 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 up to 80% efficiency. Our cross flow heat exchangers, coupled with evaporative cooling technology, provide an efficient, low cost and environmentally friendly alternative to traditional methods of cooling data center electronics.
Model H2 is our most efficient cross flow plate heat exchanger. It combines low-weight with high differential pressure resistance and is able to reach typical dry temperature efficiencies above 80%.
The efficiency is improved by its slim profiles and our latest patented plate design, creating high turbulence even at lower velocities while keeping pressure drop low.

Model H is Heatex’ original cross flow plate heat exchanger with typical dry temperature efficiency up to 65% for a single pass and 85% for two-step arrangements.
Its well-proven plate design creates turbulence even at lower velocities which, combined with high channel heights, results in a low-pressure drop and a total increase in efficiency.
