Your business demands precision airflow control for critical spaces. It is a matter of safety, pure and simple. Safety for world-class research laboratories. Safety for collaboration in the world of emerging sciences. Safety for patients and staff in state-of-the-art hospitals. For your critical room control system needs, Phoenix Controls is simply the best in the business.

For more than 25 years, the name Phoenix Controls has meant peace of mind for thousands of corporations around the globe. Their customers know the quality and reliability of the Phoenix Controls venturi valve and control system is second to none. Yes, we know safety is the primary reason customers choose Phoenix, but today, there are even more reasons to design our valves into projects. Their innovative airflow control solutions provide new ways to save energy and reduce the cost of maintaining HVAC systems.

As building airflow control systems become more complex, their maintenance costs rise. Phoenix Controls delivers the value of an energy efficient critical room control system that requires virtually no maintenance for the entire life of the building.

 

Product Advantages

Accel® II venturi valves are built and characterized at Phoenix Controls’ headquarters to ensure quality workmanship that reflects years of Phoenix Controls engineering advancements. This high-performance, airflow metering device is the foundation of every airflow control system they provide and is backed by a five-year warranty. Its reliable performance has been proven in a wide range of critical environments, including laboratories, Vivariums, pharmaceutical clean rooms and healthcare facilities.

When a building has critical airflow control requirements, testing and balancing (TAB) can be difficult and time-consuming. Without the right device, you may find yourself doing it over and over. These redundant efforts are eliminated by installing the Accel II venturi valve. Its true pressure-independent performance and factory characterization saves time and money by reducing TAB time and ensures stability in room pressurization. TAB time is also reduced because every valve is factory characterized with a 48-point flow curve on NIST-certified valve characterization station at their US headquarters. This means that as soon as the valves are installed, most of the system commissioning can be completed before the fans are ever turned on.

Additionally, long-term stability is assured with true pressure-independent performance. Once the building system is running, conditions will change and so will system static pressures. The Accel II venturi valve’s unparalleled pressure-independent performance pays dividends with constant airflow control accuracy and proper room pressurization. This high-performance, airflow-metering device is the foundation of every airflow control system we provide whether it’s Celeris, Theris, Traccel, or Analog.

Benefits include:

  • Factory characterization reduces TAB time.
  • Inlet and exit insensitivity allow for less costly ductwork designs.
  • Long-term system stability assured with true pressure independence.
  • No routine maintenance.
  • High turndowns of up to 20:1.
  • Speed response of less than one second when required.
  • Proven ability to help achieve LEED certification and Green Guide for Healthcare recognition.

Approach

The most commonly used airflow control device is the Terminal box or VAV box. While this device has always done a great job of providing tempered air into a space for comfort control, it typically falls short when trying to maintain directional airflow or proper pressurization.

Back in the 1980s, Phoenix Controls began developing and modifying a venturi valve for use in laboratories where fume hoods were being used. The traditional approach to these spaces was the VAV box and while they did a good job of maintaining temperature, they demonstrated an inability to consistently provide proper airflow and pressurization. To compound the problem, differential pressure sensors were used to control airflow devices and for maintaining room directional airflow. A very challenging method when doors are often left open.

For these reasons, Phoenix Controls developed a unique approach to maintaining directional airflow. This simple concept is called the “Volumetric Offset” approach. The theory is that if you are able to accurately exhaust more air from a space then what is being brought in, additional air would infiltrate the space to make up the difference: Exhaust volume = Supply volume + Offset. In fume hood laboratories where the door(s) are opening and closing often, the volumetric offset approach was, and still is the best solution.

Additionally, when working with fume hoods there is often a need for additional inputs and outputs for the various pieces of control equipment.For that reason, their Celeris® system offers the best solution as each valve controller comes with its own feature-rich controller to offer the most flexibility.
Traccel logo
Life Sciences share the same requirement for proper directional airflow. In facilities where animal research takes place, or where Vivariums are used, proper pressurization is critical. In facilities where biological research is conducted (BSL), there are often multiple levels of pressurization from the corridor outside to the space within. These applications are not as demanding at the controller level, and for that reason, the Traccel® system is the best choice. Traccel uses the same valves and volumetric offset approach but does not share the same requirement at the controller level.
Theris logo
Likewise in a healthcare setting, proper directional airflow is needed but the applications are not as intensive as a wet chemistry research laboratory. For that reason, Phoenix Controls has developed the Theris® platform. Theris has been designed to fit the needs of the typical operating suite, isolation room or patient room while using the volumetric approach and Accel II venturi valves. Theris and Traccel use the valves in Tracking Pair applications to accomplish room level pressurization and temperature control. Lastly, in Healthcare facilities around the world, whether protecting the patient in an Isolation Room or protecting the patient undergoing surgery, maintaining directional airflow and proper pressurization is one of the best weapons available in the fight against the spread of disease and infection. Through the years, Phoenix Controls has become the choice of engineers, architects, and owners when selecting airflow control equipment to handle the pressurization of their critical spaces.
