Pharmaceutical Process Areas
Pharmaceutical
research and manufacturing facilities must adhere
to rigid environmental control procedures to assure
research integrity and to protect products from contamination.
The amount of airflow, temperature and humidity must
be monitored and maintained at certain levels to ensure
contamination does not occur. As a result, pressurization
is essential. Without pressurization, it is virtually
impossible to achieve precise, reliable, and repeatable
control within these areas.
Because
of these requirements, pharmaceutical process areas
need airflow control systems that can react to fluctuations
quickly and maintain the desired positive or negative
pressurization. The Phoenix Controls Celeris Accel
II valves may be used to modulate the airflow into
and/or out of these spaces to maintain the desired
positive or negative space pressurization.
Progressive
Offset Control Sequence of Operation:
Small Cleanroom with Exhaust Side Control
Progressive Offset Control (POC) is an application
developed by Phoenix Controls that actively maintains
space pressurization control based on the pressure
differential between a reference and the space under
control. The configuration of the space pressure control
accomplished varies, depending on the specific requirements
for the rooms under control.
The
advantages of this application are:
