When monitoring critical environments, safety needs to be maintained. Whether it is in compounding pharmacies, cleanrooms or operating rooms there are always regulatory standards that need to be met.

Monitoring many environmental parameters is usually required, the most common examples of telemetry points are:

  • Volatile Organic Compounds (VOC)
  • Carbon dioxide (CO2)
  • Light levels
  • Door status
  • Air velocity
  • Particulate count
  • Temperature
  • Relative humidity
  • Differential pressure




To monitor all these parameters, it’s very important to put this cumulative data into one device. This reduces risks of data being overlooked as it will all be in one place.

The best solution for monitoring multiple parameters from a single point is using a room pressure monitor - the Setra FLEX. This can monitor up to 18 parameters on one device simplifying use and reducing construction during installation. The FLEX is fully BACnet compatible, allowing for seamless integration into building manageSetra FLEXment systems.


Let’s take a deeper look into the FLEX

With the added control capability and alarming functions from the FLEX, it can help manage the critical environment in more than one way: 

The FLEX gives direct control of equipment, such as hydronic reheat valves and air flow dampers. FLEX’s direct control uses PI (Proportional-Integral) control loops that can be tuned for optimum equipment calibration. Additional third-party controllers are not required as the FLEX eliminates this.

When equipment is under control by others, FLEX can write new setpoint values to command changes in pressure, airflow, humidity, temperature, or any user defined parameter. The FLEX allows for BACnet setpoint override because it features an override duration and cancel feature. This way the override value can be set to expire at a specific time, enabling energy savings.


All features of the FLEX apply to all the badges on the home screen.

The FLEX can be used to control the damper valve that modulates the pressurisation in the room directly. Then, when the room is empty or being serviced, the end user can place the FLEX into standby mode to conserve energy or they can reduce the differential pressure point.

In a hospital, when patients or healthcare professionals want to adjust the temperature to comfortable levels, they need to adjust the setpoint via the home screen of the FLEX – this can be done with ease. If needed, the setpoint adjustments can be pre-configured to a certain duration and range.
