HVAC control in clean rooms ensures critical conditions of air purity, pressure, temperature and humidity for sterile processes.

Description

The HVAC system is the heart of a cleanroom, whose primary mission is to isolate the environment from external contaminants. To achieve this, differential pressure is critical: a higher pressure is maintained in the cleaner areas compared to adjacent areas, creating an outward airflow that mechanically prevents the entry of particles or microorganisms. Without this pressure gradient, the integrity of the space would be compromised by any door opening.

On the other hand, tight control of humidity and temperature is vital for both process stability and personnel safety. Uncontrolled humidity can encourage microbial growth or generate static electricity that can damage electronic components. Likewise, a constant temperature ensures that chemical reagents and equipment operate under precise parameters. Together, these three factors guarantee a sterile and controlled environment, and the use of high-precision sensors is essential to monitor any deviations and ensure continuous room operation.
