How does a decentralised dual-flow CMV system work?

A decentralised dual-flow CMV allows for continuous replacement of extracted stale air with fresh air intake, meaning better results in terms of energy efficiency and purification of incoming air.

A decentralised dual-flow CMV (also known as a split CMV) consists of two equally-powerful electric fans, one for the extraction of stale air and the other for the simultaneous delivery of fresh air into the same room. Outgoing and incoming air pass through a heat exchanger without ever touching each other. The recovery performance of this category of equipment is on average higher than that of push-pull decentralised CMV systems and can easily reach and exceed even 90%.As is the case for the Helty Flow Easy and Flow Plus, these devices are designed and built to properly manage the ventilation needs of individual rooms or premises up to 20m² and have the significant advantage of being easy to install and maintain.
They are particularly suited to renovations and energy upgrading because they do not require pipes running through the house: each individual unit is installed in the room it will serve.
