Failing Fume Hoods were Restored, Airflow Safely Controlled, and Forecast Savings were Achieved
The Phoenix exhaust system was getting old and managers questioned whether the 21 laboratories ever operated properly because the RTUs operated continuously at maximum capacity, and the work space was often too humid. Unfortunately, a trial of installing extra fans had not been able to solve the supply/exhaust or humidity problems.
TEL did a great job retrofitting the equipment without disrupting client operations.
We demonstrated energy savings immediately because the AHU load was reduced so much. Good job!”

Auto sash controllers have advanced significantly in recent years but TEL still leads the field...
We have a video showing how the TEL Auto Sash Controller integrates with VAV systems for safe airflow and energy savings of up to 85%.
People working with industrial and educational fumehoods must be protected at all times. Auto sash controllers keep people safe.
Today’s safe and efficient laboratories are a given, but fume hood health and safety standards were only introduced 25 years ago…
