Air Handling Units (AHUs) are critical components of HVAC systems, designed to regulate and circulate air as part of heating, ventilation, and air conditioning processes. Among their many functions, maintaining optimal humidity levels is vital for both occupant comfort and system efficiency. This is where humidifiers come into play.
At iACS, we specialise in manufacturing tailored AHU control panels and providing a vast inventory of over 6,000 HVAC parts. This guide dives deep into how humidifiers function within AHUs, helping you make informed decisions for your HVAC system.

Why Humidification Is Essential in HVAC Systems
Humidity control is about more than comfort; it’s about creating healthy indoor environments. Proper humidity levels:
- Prevent respiratory irritation caused by overly dry air.
- Protect sensitive equipment and materials like wooden furniture or artwork.
- Ensure compliance with industry standards in environments like hospitals, laboratories, or data centres.
In an AHU, humidifiers are the key to achieving these benefits by regulating moisture levels in the air.
How Humidifiers Work in AHUs
Humidification Process
A humidifier in an AHU adds moisture to the air to maintain desired humidity levels. The process generally involves:
- Measurement and Control: Sensors measure the air's relative humidity and signal the control system if adjustment is needed.
- Water Introduction: Water is supplied to the humidifier unit, where it is transformed into vapour or fine droplets.
- Air Mixing: The humidified air is mixed with the AHU’s airflow and distributed throughout the building.
The integration of a humidifier into an AHU ensures consistent air quality and precise environmental control.
Types of Humidifiers Used in AHUs
Different humidifiers suit varying applications. The most common types in AHUs include:
- Steam Humidifiers:
These generate steam from boiling water, which is injected into the airstream. They are highly effective for applications requiring precise humidity control, such as healthcare facilities. - Evaporative Humidifiers:
These pass air over a water-soaked medium, allowing evaporation to add moisture. They are energy-efficient but may be less effective in low-temperature conditions. - Ultrasonic Humidifiers:
Using high-frequency vibrations, these units create a fine mist that mixes with the air. They are compact and efficient, ideal for smaller systems. - Adiabatic Humidifiers:
These systems use the energy from the surrounding air to evaporate water, making them highly efficient and eco-friendly.
Benefits of Humidifiers in AHUs
- Energy Efficiency: Proper humidity reduces the load on heating systems, resulting in energy savings.
- Comfort: Humidified air prevents dryness, improving occupant satisfaction.
- Health Benefits: Minimising dry air reduces respiratory issues and the spread of airborne viruses.
- Preservation: Maintaining balanced humidity protects materials like wood and electronics from damage.
Common Maintenance Tips for AHU Humidifiers
To ensure optimal performance, follow these maintenance tips:
- Regularly inspect and clean the humidifier components to prevent scale buildup.
- Replace worn or damaged parts promptly to avoid system inefficiencies.
- Calibrate sensors to ensure accurate humidity control.
- Flush the water supply lines periodically to avoid blockages and bacterial growth.
At iACS, we offer a wide range of spare parts and maintenance solutions to keep your AHU running efficiently.
Choosing the Right Humidifier for Your AHU
Selecting the right humidifier depends on factors like:
- Application Requirements: For critical environments like hospitals, steam humidifiers offer precise control. For general office spaces, evaporative models may suffice.
- Energy Efficiency Goals: Adiabatic humidifiers are eco-friendly, while ultrasonic models are compact and efficient.
- System Compatibility: Ensure the humidifier integrates seamlessly with your AHU and control panel.
