The Phoenix Controls Legacy “We Don’t Measure Flow” ® Flow Metering vs. Flow Measuring

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

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
