Air Handling Unit (AHU)
What is an Air Handling Unit (AHU)?
An Air Handling Unit (AHU) is responsible for filtering, conditioning, and regulating air through advanced filtration systems, such as HEPA and ULPA filters, which remove up to 99.999% of airborne particles.
It is an essential component of ventilation and air conditioning systems, designed to regulate and improve indoor air quality. Its main function is to condition the air through filtration, heating, cooling, humidification, and dehumidification processes, according to the specific requirements of each environment. These units ensure that temperature, humidity, and air cleanliness parameters are maintained within established limits, ensuring an optimal environment for critical operations.
Air treatment in cleanrooms is crucial for maintaining a controlled environment free of contaminants that could affect the quality of sensitive products or processes. These facilities are used across various industries, such as pharmaceuticals, microelectronics, biotechnology, and medical device manufacturing.
Components of Air Handling Units
Here are some of the main components and considerations for air treatment in cleanrooms:
Air Filters
- Pre-filters: Used to remove larger particles from the air before they reach the high-efficiency filters.
- HEPA Filters (High Efficiency Particulate Air): Capture 99.97% of particles as small as 0.3 microns and are essential for maintaining air cleanliness.
- ULPA Filters (Ultra-Low Penetration Air): Used in applications requiring even higher cleanliness levels, capturing 99.999% of particles as small as 0.12 microns.
Humidity and Temperature Control Systems:
- Humidifiers: Maintain the required humidity level, as both low and high humidity can negatively affect the cleanroom environment.
- Dehumidifiers: Remove excess moisture to prevent condensation and microbial growth.
- Temperature control: Crucial for worker comfort and the stability of processes.
Classification of AHUs by Size
Air Handling Units (AHUs) are integrated systems that manage air filtration, heating, cooling, and humidification. They include fans, heat exchangers, and humidity control devices.
Compact Units
Compact air handling units are essential for optimizing environmental control in confined spaces, such as laboratories and production areas requiring specific cleanliness and temperature conditions.
These units are designed to provide an efficient and flexible system, adapting to the particular needs of each facility thanks to their small size and modularity. Compact units integrate advanced filtration, climate control, and humidification functions, ensuring air quality and protection against contaminants, particles, and thermal variations.
Their easy installation and maintenance, along with their ability to integrate into existing HVAC systems, make these units the ideal solution for environments that need to maintain strict quality and environmental safety standards.
Furthermore, compact AHUs are a sustainable and cost-effective option for companies seeking to reduce their carbon footprint and optimize energy consumption, contributing to a healthier and more efficient environment.
Modular Units
Modular air handling units are the ideal solution for facilities that require flexibility and customization in air handling, such as laboratories, hospitals, and production plants.
These units are designed to be highly adaptable, allowing for configuration according to the specific needs of the space and type of application.
Thanks to their modular design, these units can be easily expanded or modified to incorporate new functions or increase capacity, making them a long-term, scalable investment.
Modular units integrate advanced filtration, temperature control, and humidification systems, ensuring a controlled, contaminant-free environment. Additionally, these units are energy-efficient, helping businesses reduce operating costs and minimize their environmental impact.
With easy installation and maintenance, modular air handling units offer a versatile and reliable solution for maintaining the highest air quality standards in various critical environments.
