21.1 Product range overview
Critical Environment Technology (CET) is a range of reliable air volume flow
controllers and supplementary components for the secure, precise and fast
measurement, control and monitoring of air volume flows and room pressures
in buildings. CET can be easily integrated into building automation systems.
The overall system thus provides maximum efficiency, cost effectiveness and
security.
CET was designed for:
● Room ventilation and general extractions
● Room pressure control
● Laboratory fume hood control
● Room air conditioning
CET is suitable for the following areas of application:
● Chemistry laboratories
● Clean rooms
● Laboratory rooms
● Operating theatres
● Sickrooms
● Production rooms
● Storage rooms
● Laboratory fume hoods
● Canopy hoods and extractions
The DXR2.E17C and DXR2.E17CX room automation stations are perfectly
suited for buildings requiring room pressurization and fume hood control. They
measure room pressurization, ventilation, and control supply airflow to the room
and extract airflow from the room.
The room control application types for the DXR2.E17C automation station (30
data points) contain the controls for one segment. The room control application
types for the DXR2.E17CX automation station (60 data points) contain the
controls for two segments.
The room pressurization application types in either room automation station
can coordinate multiple segments contained in other controllers and coordinate
up to 8 fume hoods in one room.
The fume hood control application type for the DXR2.E17C automation station
and the fume hood application type for the DXR2.E17CX automation station
contain the control for one segment.
