Industrial Ventilation

Dehumidification and Energy Recovery

Many industrial processes generate large amounts of hot and humid air. These processes have a high potential for energy and heat recovery, which reduce energy consumption drastically, consequently minimizing costs as well as the environmental impact. Humidity control is a significant aspect of many types of process industries. Since humidity affects almost all materials, it is a particularly important factor to take into account for industries processing hygroscopic materials.

Air-to-Air Heat Exchangers and Industrial Applications
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 to give an alternative, customized solutions. Our heat exchangers are available in different materials to fit in various environments. This also applies to the sealing and coating materials.

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 wide plate spacing and opened plate design enables 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. Open plate spacings allow for easy cleaning. Optional epoxy coated plates and powder coated framework prolongs the service life of the exchangers in corrosive environments. Other suitable application areas are, for example, drying grains or tobacco.

Dehumidification
A combination of crossflow and rotary exchangers is an effective way to manage humidity in challenging locations, such as tunnels and mine shafts while minimizing overall energy consumption.

Process heat recovery
In processes where large amounts of waste heat are generated, Heatex 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 standard range keeps the internal leakage rate down 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 Heatex 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.
