Many industrial processes generate large amounts of hot and humid air. These processes have great potential for heat recovery, and air pollution control, which reduces energy consumption and environmental impact.
Process Heat Recovery In processes where large amounts of waste heat are generated, air-to-air crossflow heat exchangers can be employed to recover energy from contaminated air streams. The recovered energy can then be used to preheat the incoming process air, significantly reducing overall operating and production costs. Heatex plate heat exchangers keep the internal leakage rate below 0,1% of nominal airflow.
Equipment Energy Recovery Many industrial and manufacturing finishing processes, e.g., automotive paint booths, require well-functioning ventilation. This often leads to a large volume of high-temperature air, which requires high amounts of energy. Both air-to-air crossflow and rotary exchangers are excellent choices for energy recovery, significantly reducing operating costs. The stability and open plate design of Heatex plate heat exchangers allow for good cleaning possibilities of built-up paint contamination.
Condensation and Process Drying The high effectiveness and large plate area make Heatex crossflow heat exchangers an excellent choice for vapor condensation and removal. For drying textiles, garments, and finished goods, Heatex’s wide plate spacing, and open plate design enable the extraction of fibers. The optional silicon sealant allows temporary vapor temperatures up to 200 °C. For wood drying, the wide range of sizes of Heatex crossflow exchangers accommodates large flow rates and still low velocities and low-pressure drops.
Air-to-Air Heat Exchangers Heatex air-to-air heat exchangers are ideal for numerous industrial applications, including dehumidification and water removal, process heat or refrigeration recovery, and humidity transfer. Compared to liquid-to-air heat exchanges, air-to-air heat exchangers are simpler to install, easier to maintain, and more economical to purchase and operate.
Heatex provides a wide range of models, sizes, and configurations. Also, we can produce models that are beyond the standard offering that require alternative, customized solutions. Our heat exchangers are available in different materials to fit various environments. This also applies to sealing and coating materials.

Depending on the requirements, we offer a wide range of plate heat exchangers. Each model is customizable but has distinct advantages.
Model H2 is our most efficient cross-flow heat exchanger to date.
Model H has the widest set of options and configurations.
Model Z is designed to operate in extremely corrosive environments and heavy-duty applications.

Model E offers one of the most compact casings available on the market. This gives exceptional efficiency compared to conventional rotary exchangers with the same casing dimensions. The airflows may be oriented side by side or top/bottom, and the complete rotor may be installed in a vertical as well as a horizontal orientation.
Model EQ features a segmented wheel that facilitates onsite installation or replacement in narrow spaces, which also provides for lower transportation costs. It is possible to make adjustments to the position of the shaft in all directions for a perfectly balanced fit in the air handling unit.

Experience has shown that significant corrosion is likely to occur if the relative humidity is above 80% and the temperature is above 0°C. However, corrosion occurs at much lower humidity levels if pollutants and/or hygroscopic salts are present. Corrosivity classes combined with typical applications can be used to define material selection. See the table below.
Heatex has a broad product offering and can supply materials depending on each end-user needs. For cross-flow heat exchangers, the heat transfer surface is by standard aluminum. However, in harsher environments, like coastal installations with high salinity or more polluted industrial applications, we recommend using epoxy. In even more demanding applications like heavily air-polluted industries and offshore wind turbines, we recommend multilayered epoxy or stainless steel.
Epoxy is also available for rotary heat exchangers.
