Ventoxx Double - double air exchange in one decentralized heat recovery unit!

Ventoxx Double HRV consists of an insulated rectangular housing containing two air ducts and a double set of accessories, similar to the Ventoxx Harmony HRV design. It allows this model of ventilation unit to reach the highest level of performance from the entire product range of VentoxxTM while remaining quiet and easy to use.

High-quality Austrian or German ceramic heat exchanger due to its optimal thermal-physical properties and advanced cell structure provides heat recovery (return) efficiency up to 94%! Ceramic is a hygienic material - the heat exchanger is not susceptible to the formation of bacteria, is not subject to frosting, and performs its functions without damage to the efficiency of recovery even at temperatures down to -20 °C.

The decentralized heat recovery unit is controlled by an ergonomic remote control that allows users to select the ventilation speed as well as the operating mode. Temperature operation of Ventoxx Double HRV without loss of quality is possible in the range from -20 to +60°С.

The combined wall panel of the decentralized heat recovery unit not only blends seamlessly into any interior but also displays the current unit operating mode with an unobtrusive indication. If desired, the indication of operating modes on the panel can be disabled.

Wall panels can be made in different colors, depending on the color scheme of the interior and customer preferences. The colors available to order can be selected from the standard set or ordered individually in any color from the RAL color chart.

The Ventoxx Double HRV series are equipped with G3 class washable filters that not only protect the decentralized heat recovery unit from dust but also prevent insects from entering the rooms. The recommended frequency of filter cleaning is once a quarter and its replacement are every two years.

New! Installation on any floor without the involvement of high-rise building construction workers.

The decentralized ventilation unit with heat recovery comes fully assembled and ready to install in the intended wall opening which significantly saves your time during installation. Installation is performed simply by sliding the unit body into the prepared hole on the room side. Thus, it is now possible to completely eliminate the need for the services of high-rise building construction workers during installation.
