Humidity control

Humidity control in Swegon GOLD air handling units is designed to maintain optimal indoor humidity levels for comfort, health, and building protection. The system supports both humidification and dehumidification, adapting to varying climate and building needs.

Why should you activate it?

In cold climates, indoor air often becomes too dry, while in summer, excess humidity can compromise comfort and energy efficiency. Traditional systems struggle to balance moisture without wasting energy or adding complexity.

Proper humidity control is essential for a healthy and comfortable indoor environment. Too little humidity can cause dryness and discomfort, while excessive humidity can lead to condensation, mold growth, and damage to building materials. Maintaining the right humidity level also helps protect sensitive equipment and supports overall well-being for occupants.

Humidity control is ideal for schools, offices, elderly homes and other buildings where a stable indoor climate is important. For example, in an office building during winter, the system helps prevent dry air, improving comfort for everyone. 

Main benefits

The humidity control function and GOLD sorption rotor technology (RECOsorptic), are ideal to combine.

Key benefits include:  

  • Consistent comfort: Maintains stable indoor humidity, preventing dryness or excessive moisture that can affect comfort and health.
  • Health protection: Reduces the risk of respiratory issues, allergies and mold growth by keeping humidity within recommended limits.
  • Energy efficiency: Recovers moisture naturally, reducing the energy required for artificial humidification or dehumidification.
  • Building preservation: Prevents condensation and moisture damage to building structures, furnishings, and sensitive equipment.
  • Smart integration: All humidity control functions are managed via the GOLD unit’s control system, with easy access to settings and monitoring through the handheld terminal or web interface.

How does it work?

The humidity control function operates automatically in the background, using advanced sensors and smart algorithms to maintain optimal indoor moisture levels.

Here’s how it works:

  • The system uses five sensors (outdoor air, supply air, room, extract air, exhaust air) to monitor humidity and temperature.
  • The sorption rotor speed is automatically adjusted to optimise moisture transfer based on real-time conditions. 
  • In winter, the system recovers humidity to prevent dry air; in summer, it limits moisture recovery to avoid high humidity.
  • A drying function can be activated temporarily to prevent indoor humidity peaks.
  • All logic is fully integrated into the GOLD control system, requiring no extra manual adjustments.
