Industrial Ventilation

Energy Recovery

Many industrial processes generate large amounts of hot and humid air. These processes have a great potential for energy, heat recovery and air pollution control, which reduces energy consumption and environmental impact.

Industrial Ventilation and Energy Recovery

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 wide plate spacing and opened 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. 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.

Dehumidification Solution
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.

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 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.


Recommended Products
Heatex Model E and Model EQ

Model E offers one of the most compact casing available on the market. This gives an exceptional efficiency compared to conventional rotary exchangers with the same casing dimensions. The airflows may be oriented as side by side or top/bottom, and the complete rotor may be installed in a vertical as well as in 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.

Heatex Model H2, Model H, Model P and Model Z

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 P is our most robust aluminum heat exchanger.

Model Z is designed to operate in extremely corrosive environments and heavy-duty applications.

Application Examples
wood drying
Wood Drying Processes

To eliminate the risk of dampness and mold growth in wood drying industries air-to-air heat exchangers can be used to dehumidify the air through condensation and recover heat.

paint booth
Painting and Spray Booths

In buildings where corrosive gases are mixed into the air, air-to-air heat exchangers can be used to separate airflows and recover heat.
