SEVentilation ductless hrv units do not require traditional ducting. This is due to every single unit being equipped with it´s own heat buffer eliminating the need for additional ducting or suspended ceilings in your house or to hire specialists to clean out the entire system on a regular cycle.

Depending on your room size you may need only one set for the area you wish to ventilate. The units are fitted to an exterior wall and operate in synchronisation with each other. One sucks in fresh air whilst the other blows stale air out of the room and they then switch function every 75 seconds, using the heat from the expelled air to warm the fresh incoming air.

The heat recovery performance is up to 90%, which means the stale air leaves the room with a temperature of 20° Celsius and the fresh air returns into the room with 18° Celsius. Compared with other ventilation strategies (purging, trickle vents, DCV), you´ll save heating energy and money because the incoming fresh air is already preheated.

SEVi ductless HRV-Systems are easy to install and maintain. Every HRV-Unit runs on 12V DC and all required maintenance can be done by yourself. For example - the heat buffer is built for cleaning in a domestic dishwasher. And there´s no risk of cultivating germs and bacterias in hard-to-reach (and hard-to-clean) ducting.
