Critical Environment Technology (CET) enables safe, precise, and fast measurement, control, and monitoring of air volume flows and room pressures in life science cleanrooms. Using open-standard interfaces, CET integrates seamlessly into building automation systems.

Demand-controlled ventilation supports room ventilation, exhaust systems, room pressure control, fume hood control, and room air conditioning. Energy efficiency can be increased by up to 50% while maintaining all safety requirements.

Siemens provides fully integrated and intelligent building automation solutions designed to meet the strict regulatory requirements of the pharmaceutical and life science industries. These systems efficiently control and monitor all cleanroom parameters relevant to process and product quality, including environmental emissions, while enhancing energy efficiency and lowering operating costs.

Key features include dynamic pressure and volume flow control, calibrated humidity and temperature sensors, exact modulating magnetic valves for precise control, and demand‑driven adjustment of lighting and shading. Convenient room displays provide clear overviews of critical parameters and alert users to warnings or alarms.

Cleanroom safety has two dimensions: ensuring that only authorized personnel can access sensitive areas, and protecting people and assets inside the cleanroom environment. Siemens solutions combine access control, intrusion detection, and continuous video surveillance to provide reliable access control.

Centralized recording of user activities and clear overviews of all personnel present support transparency and safety in critical areas.

The Airlock Interlocking System is an integrated airlock control solution based on standard building automation controllers. It operates autonomously and can be quickly adapted to the specific requirements of a cleanroom facility.

Integration with the building management system enables advanced functions such as gas-detection-based locking, dynamic adjustment of purge times, and management of people flow through integrated access control.

To minimize the risk of cross-contamination caused by people, processes, or equipment, Siemens solutions support clearly defined procedures and reliable control of physical access to restricted zones.

Sophisticated consequential processes help ensure compliance with cleanroom protocols and protect sensitive environments.

People and assets in cleanrooms require the highest level of protection. S‑LINE fire detectors provide the earliest possible fire detection, while Sinorix™ fire suppression systems offer solutions for a wide range of fire types. Integrated explosion protection further enhances safety in cleanroom environments and supports the protection of people and assets.

In emergency situations, intelligent evacuation systems are automatically activated, combining emergency voice communication and emergency lighting to provide clear instructions, prevent panic, and support orderly evacuation.

Siemens technology and validation specialists enable reliable monitoring of cleanroom conditions and airborne particles in critical environments to support GMP compliance. Solutions monitor, store, and document GMP‑relevant parameters such as temperature, humidity, air velocity, air pressure, particle concentration as well as access to quarantine areas and highly sensitive medical systems.

Standard solutions can be pre‑configured for data acquisition, visualization, and archiving, operated via an integrated touch panel or networked PC, and integrated with systems such as airlock controls and presence detection.
