The Celeris® brand of products are designed specifically for fume-hood intensive, high-level containment and pharmaceutical manufacturing facilities and protects researchers and safeguards the integrity of a research environment in critical control environments while offering optimum energy efficiency.
Leveraging the proven accuracy, stability and reliability of the Phoenix Controls Accel® II venturi valve, the Celeris system provides a flexible and feature rich solution for all your airflow and climate control needs. The Celeris environmental control system integrates seamlessly with BACnet capable Building Management Systems.
|Building on the foundation that made Phoenix Controls the premier fume hood control system, we have applied the following principles to valve level, room level, and suite level control:|
|Precision ventilation and pressurization control over wide flow ranges
||The Accel II valve accurately meters flow over turn down ranges of 20 to 1 to within ±5% of flow.|
||Automatically compensates for changes in duct static pressure|
|Unmatched Speed of Response
||Independently respond to changes in air flow command or duct static pressure in 1 second or less|
|Inlet and outlet insensitivity
||Unique design and flow metering technologyeliminates the need for straight duct runs upstream or downstream of the Accel II valve|
Available with electric or pneumatic actuation, the Celeris valve mounted controller leverages LonWorks technology to create a peer-to-peer control network capable of performing sophisticated control strategies. Input and output connections on each valve controller provide sufficient I/O for connecting sensors and actuators.
The highly configurable applications resident in the Celeris valve controllers utilize the LonWorks network to provide tremendous flexibility in implementing the desired room-level control strategy.
|Grouped into basic functions the Celeris capabilities include:|
|Zone balance control
Provides superior ventilation and pressurization control by monitoring and controlling all networked and non-network flow devices in the pressurization zone. Advanced control features are built in:
- Indoor Air Quality (IAQ) Control – decrease air change rate when air quality is good to reduce energy consumption. Increase air change rates if air quality deteriorates
- Return air control – vary the ratio of 100% exhaustto return air based on indoor air quality
Provides basic cooling and reheat control with 2nd stage of cooling or heating control or use more sophisticated control schemes:
- Control off of the average of multiple temp sensors
- Set up to four temperature zones per pressurized space
- Discharge temperature control
- Discharge set point reset control
- BTU Compensation
- Thermal Anticipatory Control
- Hot Deck/Cold Deck control
||The BMS can adjust the air change rate and temperature set points based on work schedules to reduce energy consumption during unoccupied periods. Users may override the occupancy schedule on a room by room basis.|
||Control local humidification and dehumidification systems to maintain optimum comfort|
||Initiate configurable flow conditions in response to local events (purge mode, decontamination mode, decommission mode) up to nine different states|
Many built-in functions provide opportunities for substantial energy savings, reduced installation costs and as with all Phoenix Control products no on-going maintenance expense. These types of benefits can help an organization achieve many of its goals from dollar savings to LEED certification
