Service Description


As laboratory ventilation testers, sometimes we encounter problems like this. One researcher come to tell you that he can smell xylene in the lab, but there are no chemicals on the work surfaces. All chemicals are used in the fume hood.

There is no leakage from the fume hood, but you still smell xylene when entry the lab, why?
 

Re-Entrainment
 

Service Content


ICT2 has rich experience in this situation. Our professional testers know Re-entrainment very well. When the air outlet of ventilation equipments(such as fume hoods) is too close to the air handling system, this situation will take place. It will cause contaminants are put and catch to air handling system and take back to laboratory. Re-entrainment will not only become the source of pungent odors, but also has possibility of causing serious health hazards.
