Theris Flex Control Valves

High-performance, variable air volume airflow control valves for fume hood intensive, high-level containment, and pharmaceutical manufacturing facilities.

Solutions / Applications

Phoenix Controls many years of experience started with critical laboratory controls where life safety is

paramount. Safety is the fundamental base for all products and applications we develop. While

laboratory airflow is the largest part of our business we have branched out into vivariums, biocontainment,

cyclotron, forensic, petrochemical and other markets such as healthcare.

While each of these types of facilities has unique requirements there are common elements such as

100% outside air, concern about energy costs, emergency response and long term maintenance.

Advantages of Phoenix Controls

  • We have addressed these concerns with unique technologies and approaches such as Usage Based
  • Controls, Optimizer, Phoenix VIEW and Supervisor dashboards that connect users to their systems in a
  • way that provides useful information to run their buildings safer, smarter, in compliance and energy
  • Critical Applications
  • Chemistry
  • Life Science
  • Healthcare
  • Clean Spaces
  • Biocontainment

Theris Flex Valves offer a versatile, cost-effective way to introduce pressurization and accurate airflow into sensitive spaces where such capabilities might previously have seemed cost prohibitive.

The onboard controller can also be programmed with a “pandemic mode” that rapidly responds to containment or isolation needs, giving you the flexibility to adapt first-line, patient-care areas into multiple use states when needed.

Increase the overall resilience of your facility with first-line spaces that can quickly adapt to other needs – giving you airflow accuracy within +/-10% of the setpoint:

Isolate spaces such as patient rooms or the ER department to quickly respond to contagion risks.

Optimize energy use and sustainability where turndowns in unoccupied rooms are acceptable.

Theris Flex Advantages

  • Rapid, Reversible Pressureization
  • Mechanically Pressure Independent
  • Onboard Room Controller
  • More Precise Airflow Control (Compared to a VAV Box)
  • Preassembled and characterized at factory
  • Preset accuracy eliminates balancing onsite
  • Much faster commissioning and startup
  • No flow sensors, no component drift, no sensor recalibration
