Intelligent Mechanical extract ventilation (iMEV)

by Passivent

Passivent iMEV is ‘intelligent’, in that it removes the need for any occupant interaction, automatically detecting rises in humidity and responding accordingly.
The system only increases extraction when required, so it uses much less energy as the central fan is not running at a higher speed unnecessarily. Heat loss is also reduced as iMEV relies on demand control (extraction when and where required); extraction is only increased in the areas where humidity has risen.
Two systems are available; iMEV Local which senses humidity change in rooms and allows greater extraction rate and iMEV Total which both senses humidity change in rooms and pressure differences in the system to allow greater extraction rates by increasing fan speed automatically.
