Industrial Dehumidification

Particularly in industrial warehousing and food processing, operators often face 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 lead to energy loss and pose significant hurdles for transport. However, energy consumption is a primary concern in the design of a dehumidification system. Most of the energy expended in dehumidification is used to remove moisture from the air.

Combining an industrial dehumidifier with a heat recovery unit is a perfect win-win solution for addressing humid-air issues 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 evaporators’ outlets. However, if the evaporators are not frequently defrosted, they lose their capacity to remove large amounts of moisture.
• Depending on the method used, defrosting requires time and energy.
• Moisture entering the cold store can cause slippery floors, mold, corrosion, electrical malfunctions, and deterioration of product quality.

By implementing a heat-recovery unit, such as an air-to-air heat exchanger, heat from the regeneration process is recirculated and reused in the subsequent regeneration of the dehumidifier. Heat transfer occurs without moisture transfer.

As a result, heat is retained during the dehumidifier’s regeneration, minimizing energy consumption in the industrial dehumidification process.

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 (2″ WC)
• Corrosion resistance
• Fast return on investment
