Energy efficient ventilation systems reduce harmful condensation without user intervention
iMEV continuous mechanical extract ventilation systems from ventilation specialist Passivent offer a low energy, automated approach to optimising air quality and reducing the risk of harmful condensation and mould. Requiring minimal maintenance and no user intervention, they are suitable for single houses and apartments as well as multi-residential properties such as student accommodation, care homes and hotels.

iMEV systems are ‘intelligent’: they automatically detect rises in humidity and respond accordingly. Extraction is only increased in areas where humidity has risen resulting in less energy usage as the central fan is not running at a higher speed unnecessarily. Heat loss is also reduced as the systems rely on demand control, that is, extraction when and where required.
Two iMEV systems are available: ‘Local’ which senses humidity change at the ceiling extract in a ‘wet’ room and allows a greater extraction rate, so providing local control; and ‘Total’ which senses humidity change again at the ceiling extract in a ‘wet’ room and also pressure differences in the system to allow greater extraction rates when needed by increasing the fan speed automatically, providing total control of the system. Ceiling extracts require no power source to operate.
