The Phoenix Controls Legacy “We Don’t Measure Flow”
• Flow Metering vs. Flow Measuring • Flow measuring has a limited range of operation.
• Flow measuring requires long, straight duct runs (not available in most applications).
• Flow measuring is prone to inaccuracies due to the caustic nature of laboratory exhaust air • Flow measuring has inherent time lags due to airflow dynamics • Flow measuring requires periodic maintenance Phoenix Controls Corporation—Proprietary and Confidential
Factory Calibration
• Drastically Reduces Commissioning Time • Can be pre-commissioned before supply and exhaust air is connected • No sensors to set up or flows to adjust • No routine maintenance requirements Phoenix Controls Corporation—Proprietary and Confidential

Fume Hood Decommissioning
Phoenix Controls Corporation—Proprietary and Confidential
Concept
Fume Hood Decommissioning
• Ability to reduce or turn off fume hood exhaust when not in use • Potential for huge energy savings • Teaching labs or hoods rarely used • Buildings not occupied • Understaffed research facilities • Valve options • Valve minimum (i.e., 90 CFM) • Shut ‐ off Valves (i.e., 0 ‐ 5 CFM) Phoenix Controls Corporation—Proprietary and Confidential
Function and Operation
Fume Hood Decommissioning
• Can be initiated by: • Fume Hood Monitor • Button sequence • External key switch • BMS command • Ensures safety • Sash must be fully closed to initiate mode • Mode is automatically exited if sash is opened Phoenix Controls Corporation—Proprietary and Confidential
Energy Waste Alert
Phoenix Controls Corporation—Proprietary and Confidential
Concept and Operation
Energy Waste Alert
• Notification when sash is left open and lab lights are off • Features • Light sensor incorporated in monitor • Provides audible alarm • Displays "EnrG" on monitor • Reminder to close the sashes at night Phoenix Controls Corporation—Proprietary and Confidential
Unoccupied Settings
Phoenix Controls Corporation—Proprietary and Confidential
Unoccupied Settings
• Celeris®, Theris™ and Traccel® digital platforms • Lower ACH • Relaxed temperature control • Triggered locally or via BMS schedule • Retrofit existing analog systems • Lower ACH Phoenix Controls Corporation—Proprietary and Confidential
IAQ Control
Phoenix Controls Corporation—Proprietary and Confidential
Two Ventilation Concepts
IAQ Control
• Air change rates
• Reduce minimum ACH when air is "clean" • Drive to higher ACH when contamination is detected Phoenix Controls Corporation—Proprietary and Confidential
Lab Application: Next Generation VAV Control
• Lab Multi-parameter DCV: Dynamic control of min. ACH • Now all three factors affecting lab airflow can be varied • Significantly cuts energy & first cost, while enhancing safety
Constant VAV VAV Significant energy waste 6-12 ACH 10-20 ACH* VAV Hoods 2- 4 ACH 6-8 ACH* *vivariums Thermal Load

Lab Monitoring Also Helps Ensure Lab Safety
• Validates the safe operation of a lab • Detect improper bench use of chemicals • Detect poorly containing fume hoods • Spills & rogue reactions rapidly sensed • Check lab pressurization, T & RH • Validates safe IEQ room conditions for animals • Allows for safer lab airflow control • Increased hood capture from reduced drafts • Drops room flows when dilution not needed • Greater dilution provided for spills, leaks, etc.
• 12 to 15 ACH’s can be provided automatically • Sources of leaks & emissions can be found • With fact based data, source controls can be used Phoenix Controls Corporation—Proprietary and Confidential

What it all means…
• Like most life-sciences labs, the airflows in Biodesign-B are primarily ventilation driven.
• Most labs in Biodesign-B are over-ventilated • Average ventilation flows can be safely reduced by >50% when monitoring air cleanliness and responding to spills, etc.
• There are HUGE energy savings with FAST payback! • Several other soft benefits too!
• Safer hood operation • Quieter labs • Documented performance Phoenix Controls Corporation—Proprietary and Confidential
