Critical Environments

Critical Environments are spaces within a building where highly controlled processes take place. These are typically room conditions where safety of personnel and the protection of assets is essential.

Such processes are often referred to as high-consequence applications because the consequences of poor environmental control can put people, process, or products at risk. Examples of Critical Environments include surgical operating rooms, hospital isolation rooms, laboratory fume hoods, bio-safety laboratories, vivariums, clean rooms, and pharmaceutical manufacturing facilities.


Critical Environments - Healthcare - Operating Room

Critical Environments in Healthcare are those areas where patient safety is most important, especially as it relates to the control of airborne pathogens.


Critical Environments - Laboratory - Man at fume hood

Laboratories in Critical Environments include fume hood labs, bio-safety laboratories, life sciences labs, and other research environments.


Critical Environments - Vivariums - Viviarium

Vivariums (animal facilities) are Critical Environments. The quality of the animal’s environment is vital to their well-being and thus the longevity/integrity of research.


Critical Environments - Cleanrooms - Cleanroom with workers

Cleanrooms are the most stringent of engineered HVAC environments, where every particle is monitored for size and quantity per cubic meter of air.


Over 50 years of engineering excellence

Whenever high-consequence applications take place, it is critical to have the engineered HVAC system operating reliably and at peak efficiency. This ensures the room’s environment is designed to meet stringent controls for clean air, room pressure relationships, air change rate, temperature, humidity, and the management of airborne particulates. In most Critical Environment applications, regulatory agencies perform periodic inspections of operational facilities to ensure they are compliant with HVAC codes and guidelines in each specific industry. These codes exist to establish standards of HVAC performance and reliability that are meaningful to the primary goals of personnel safety and protection of assets.
