How it all started

 

Evaqvent AB is based in Sundsvall, Sweden and was established in 2019 by Gunnar Johanson and Urban Svedberg, researchers at Karolinska Institute in Stockholm. Our previous research on work in enclosed spaces lead us onto reports of incidents where  persons were affected by toxic substances while working inside arriving shipping containers. We got funding to initiate a research project. The photo above is from our mobile laboratory brought to the container yards.

Three scientific papers have been published, i.e.; (a) identification of the types and levels of airborne chemicals, (b) assessment of the personal exposure levels, and finally (c) developing a novel method to eliminate the greater part of these chemicals through pre-ventilation

The method and equipment needed is now made available through Evaqvent AB. We have delivered units to international distribution centers, border control authorities including customs and food inspectorates. The feed-back has confirmed the user-friendliness and ventilation efficiency of our system.
