Using Heat Exchangers in Industrial Drying

Industrial drying removes moisture from materials using controlled heat and airflow. By managing temperature, air velocity, humidity, and time, industrial drying systems achieve a stable and consistent moisture level without damaging the product.

Drying wood, grain, or sludge requires substantial energy to remove moisture, making thermal energy the primary cost driver. A well-designed heat recovery system can dramatically reduce operating expenses and improve efficiency.

High humidity, dust, and airborne particles challenge performance, while substances from wet wood or sludge residues can create corrosive environments. Choosing the right materials is essential to ensure durability and avoid costly downtime.

Airborne debris also increases the risk of clogging and reduced efficiency.

Any heat recovery solution must be engineered to withstand these demanding conditions in order to deliver long-term reliability and optimal performance.

Heatex air-to-air plate heat exchangers maximize energy recovery, reduce emissions, and improve sustainability in high-humidity, high-particle environments.

You can be confident that your drying process is reliable, efficient, and lowers cost by:

  • Using optimized crossflow heat exchangers such as Heatex Model H2, H, Z2, or Z.
  • Calculating the performance requirements accurately in Heatex Select.
  • Designing and optimizing the heat exchanger according to the application demands.
  • Choosing a heat exchanger with either entirely aluminum or stainless steel materials.
  • Adding epoxy coating to the heat transfer plates.
  • Optimizing plate distances to prevent clogging (Heatex offers up to 12 mm (0.43″) plate spacing) while ensuring the highest possible efficiency.

Heatex Model H2 & H

Heatex crossflow models H2 and H should be configured with aluminum heat transfer plates and framework (profiles and end plates). Additionally, we offer a wide range of configurations and options, such as:

  • Plate sizes between 200 – 3000 mm (7.87″ – 118.1″) (depending on model)
  • Plate distances between 1.6 – 12 mm (0.06″- 0.47″) (depending on model)
  • Epoxy-coated heat transfer plates
  • Max. differential pressure between 1800 – 3000 Pa (depending on plate distance and model)

Industrial Drying Payback Example – Wood Drying

Implementing a heat exchanger to recover waste energy is always a good investment. In this example, the payback period (return on investment) will be less than a year!

This calculation is based on:

  • 50 kW heat recovery system (CAPEX 4000 € )
  • 90% heat conversion efficiency
  • 3000 h / year operating time
  • 0.64 MWh / m3 energy content (sawdust)
  • 20 € / m3 fuel cost (sawdust)
Equivalent fuel power
(Heat recovery/heat conversion efficiency)
50 kW / 90% = 56 kW
Fuel energy saving
(Equivalent fuel power x operating hours)
56 kW x 3000 h = 167 MWh
Total amount of fuel saved
(Fuel energy saving/energy content)
167 / 0.64 = 260 m3
Total fuel saving
(Total amount fuel x fuel cost)
260 x 20 € = 5 200 €
Payback
(CAPEX / total fuel saving)
4000 € / 5200 € = < 1 year
