Air Handling Units

Air handling units (AHUs) are central to maintaining indoor air quality across commercial and industrial buildings. During winter, AHUs introduce cold, low-moisture outdoor air that, once heated, results in very low relative humidity levels. Without humidification, dry air can affect occupant comfort, damage hygroscopic materials, and disrupt humidity-sensitive manufacturing processes. Integrating a dedicated humidification system ensures target relative humidity levels are maintained throughout the building.

In the UK, changing seasonal conditions require AHUs to adapt continuously to varying outdoor air temperatures and moisture levels. Depending on the application, both isothermal and adiabatic humidifiers offer effective humidity control. Isothermal systems provide precise steam humidification, while adiabatic technologies deliver highly energy-efficient moisture generation with lower operating costs. Selecting the most suitable solution depends on the building’s ventilation strategy, occupancy, and process requirements.As every AHU installation has unique operational demands, a tailored humidification solution ensures reliable climate control, improved indoor comfort, enhanced process performance, and year-round energy efficiency.
