Dehumidification and Energy Recovery | Heatex


Dehumidify with Heat Exchangers

Industrial dehumidification, combined with heat recovery, leads to less energy consumption and a shorter return on the investment period. As a result, the system as a whole is more cost-effective and attractive to purchase.

Challenges and Solutions in Dehumidification

Particularly in industrial warehousing and food processing, operators are often confronted with a pressing need to control air humidity between spaces. The colder the climate, the more critical it is to control moisture. Traditional strip curtains and high-speed doors result in energy loss and create significant hurdles to transport.

Combining an industrial dehumidifier with a heat recovery unit is a perfect example of a win-win solution for solving the problems while significantly reducing energy consumption.

Some common challenges are:

  • Moisture enters the cold store from outside through the open passage (natural heat transfer).
  • Moisture is removed via the outlet of the evaporators. However, the evaporators lose their capacity to remove large amounts of moisture if not frequently defrosted.
  • Depending on the method, defrosting takes time and energy.
  • While moisture enters the cold store creates slippery floors, mold, corrosion, electrical malfunction, and product quality deterioration.


By implementing a heat recovery unit, heat from the regeneration process is fed back and reused for the regeneration process of the dehumidifier. The heat transfer takes place without moisture transfer. As a result, heat remains in the regeneration process of the dehumidifier, keeping energy consumption for the dehumidification process to a minimum.

Besides ensuring that as much heat as possible is transferred from the exhaust air to the supply air (>80%), the heat exchanger should provide:

  • Low maintenance requirements
  • Long lifespan (>15 years)
  • Limited pressure drop (< 500 Pa)
  • Corrosion resistance
  • Fast return on investment

Heatex’s air-to-air heat exchangers have a lightweight construction, slim frames, and an optimized plate pattern that delivers superior efficiency while keeping pressure drop low.

Recommended Products for Dehumidification

plate heat exchanger

Heatex Model H & H2

Heatex crossflow models H2 and H are made of aluminum heat transfer plates and Aluzinc end plates.

Additionally, we offer a wide range of configurations and options, such as:

  • Epoxy-coated heat transfer plates
  • Corrosion protected framework
  • Plates distances between 1.6 – 12 mm (depending on the model)
  • Sizes between 200 – 3000 mm (depending on model)
  • Max. differential pressure between 1800 – 3000 Pa (depending on plate distances and model)

rotary heat exchangers

Heatex Model E & EQ

Heatex rotary heat exchangers enable humidity transfer and generally provide higher efficiency than a plate heat exchanger.

Typical options for paint booth applications include:

  • Epoxy-coated matrix
  • Corrosion protected framework
  • Power belt for high reliability, easy maintenance, and adjustment
  • Various motor options. E.g., a constant motor for simplicity or a step drive motor with frequency control and Modbus for flexibility
