Chilled water air handling units (AHUs) use a central chiller to supply cool water to an AHU's coils, which then cools and dehumidifies the air before distribution in sensitive applications like IC (integrated circuit) manufacturing and warehousing.

These custom-designed units are vital for maintaining precise temperature and humidity control, crucial for protecting delicate components and preventing defects in electronic manufacturing, and for preserving inventory quality in warehouses.

• Chiller: A chiller cools water to a low temperature.
• Piping: The chilled water circulates through a closed-loop system to the AHU.
• AHU Coil: Inside the AHU, a chilled water coil is installed.
• Heat Exchange: As air is blown across the cold coils by a fan, it releases its heat and moisture to the chilled water.
• Air Distribution: The now-cooled and dehumidified air is then delivered to the manufacturing cleanroom or warehouse space, maintaining desired conditions.

• Precise Control: IC manufacturing requires very tight control over temperature and humidity to prevent static discharge, reduce defects, and ensure high-yield production.
• Air Purity: Chilled water AHUs can be configured with features that support high-purity air requirements, essential for cleanroom environments.
• Customization: Custom AHU designs are often necessary to meet the specific needs of different manufacturing processes and cleanroom classifications.

• Humidity Management: In warehousing, especially for electronic components, humidity control is critical to prevent corrosion, degradation, and other damage to stored goods.
• Stable Environments: Chilled water AHUs provide a stable and consistent environment, preserving the quality of sensitive inventory.
• Energy Efficiency: Using a chilled water system allows for more efficient cooling and energy savings compared to other HVAC methods, especially in large facilities.
