Passivent's new, intelligent approach to efficient ventilation is proven to deliver best practice for energy saving, yet simplifies installation, commissioning and day-to-day operation.<br> <br> The ventilation company's iMEV (intelligent Mechanical Extract Ventilation) uses the established concept of continuous mechanical extraction and increases efficiency through use of the latest technology.<br> <br> A combination of humidity sensitive extracts and choice of controls ensures that in domestic dwellings, apartment blocks or multi-occupancy commercial buildings, (hotels, care homes, student accommodation), iMEV constantly delivers appropriate, adequate ventilation without detriment and with no excessive energy usage nor occupier input, Passivent explains.<br> <br> Further, the company says, a choice of fan and ducting options means installation time can be cut by up to 70%, and time-consuming valve balancing and system commissioning is eliminated.<br> <br> The standard Passivent iMEV delivers a "whole house" approach, with ventilation remaining constant until relative humidity (RH) increases. At this point the system automatically boosts airflow by up to 88% – this is more than twice as effective as other MEV systems, Passivent claims.<br> <br> www.passivent.com
