Sovereign Auto Concure 20/20 (PIV) System for Whole-House Condensation Control

Advanced Positive Input Ventilation (PIV) System for Whole-House Condensation Control

The Sovereign Auto ConCure 20/20 is a state-of-the-art Positive Input Ventilation (PIV) unit designed to combat condensation and improve indoor air quality across the entire home. By introducing a continuous stream of filtered, tempered air from the loft space, it raises the dew point and reduces the risk of condensation-related issues such as black mould, dampness, and associated health concerns.
