Duplexvent DV72R

The Duplexvent DV72 is a ventilation unit with state-of-the-art technology. Designed to provide both essential ventilation and to save you money through its heat recovery systems. This is cost effective and environmentally friendly option for residential and light commercial applications.

The DV72 offers heat recovery efficiency almost unknown to units of its size and price.

The unit is supplied with a separately mounting commissioning switch. It provides two, 100% user adjustable speed levels which can be set on installation. In addition both fans can be independently adjusted to ensure a balanced system upon commissioning.

Automatic thermal summer by-pass is activated by an internal sensor at 25ºC by reducing the speed of the supply air fan by 25%. When the supply temperature reaches 30ºC the fan reduces by a further 25%. This thermal by-pass limits the heat recovery effect by reducing the volume of warmed fresh air supplied into the dwelling. At no time will the supply fan cease to operate which ensures re-circulation.
