Ventoxx Slim Line decentralized heat recovery unit is ventilation for homes with thin walls, with a thickness of 150 mm or more. Due to the specially designed insulated expansion box, the decentralized heat recovery unit can be installed in frame houses and houses built of SIP panels without protrusion of the air duct from the structure of the building.

The insulated box of the Ventoxx Slim Line decentralized heat recovery unit allows for installation in homes with very thin walls without the formation of cold bridges that negatively affect the structural integrity of the building. Thus, despite making a through hole in the wall of the building, the decentralized heat recovery unit reliably protects against draughts and air blowing, as well as the release of unwanted condensation inside the structure.

Although this model of decentralized heat recovery units has been around for a long time, improvements have been made to it to improve key user-relevant indicators. For example, the noise load occurring during the operation of Ventox Slim Line has been reduced by using newer and more technologically advanced fans to a maximum of 23 dBA. The level of recovery (or preservation of room heat) reaches 91% due to the use of durable and frost-resistant ceramic heat exchangers from a German manufacturer.

Ceramic is a hygienic material. The heat exchanger is not susceptible to the formation of bacteria, is not subject to freezing and performs its functions without damage to the efficiency of recovery even at temperatures down to -20 ° C.
When standard-sized decentralized heat recovery units are installed in frame buildings, part of the ventilation unit is outside the building structure. During the ventilation operation in winter, the warm exhaust air passing through the part of the air duct placed outside is subject to rapid cooling. It not only causes condensation on the air handling unit, which is undesirable for the building but also negatively affects the efficiency of the decentralized heat recovery unit.

Unlike in the situation described above, the Ventoxx Slim Line HRV, due to the insulated box that hides the part of the air duct protruding from the building, provides efficient ventilation operation, even in winter. The building remains airtight and air infiltration into the house is controlled and exclusively performed through the heat exchanger that saturates the cold air with heat and saves energy for room heating.

In some cases, the Ventoxx Slim Line decentralized heat recovery unit can also be installed in a window or balcony if there is no other place suitable for the installation of ventilation.

The lack of energy-consuming electric heating up and the achievement of heat preservation solely due to the thermal properties of the ceramic heat exchanger make the Ventoxx Comfort HRV not only energy-efficient but also very economical. Minimal energy consumption during the operation of the decentralized heat recovery unit is only 2.75 W per hour at its maximum operating speed, which practically will not affect the electric power bills.

The Ventoxx Slim Line ventilation unit works in 17 operating modes, among which:  

  • Ventilation with heat recovery at five fan speeds.
  • Ventilation for fresh air supply without heat recovery, at five speeds.
  • Ventilation for air extraction without heat recovery, at five speeds.
  • Intensive ventilation of the air supply and extraction.

The decentralized heat recovery unit is controlled by the Ventoxx Twist wall-mounted control which is an illuminated rotary relay. The number of lit dots on the relay indicates the selected speed of the decentralized heat recovery unit. Illumination color allows for quick identification of the activated operating mode.

To maximize the effect of ventilation Ventoxx LLC always recommends installing the Ventoxx Slim Line decentralized heat recovery unit series in pairs. It's because the supply and extract ventilation units are operating on both the inflow and the extracting. In this case, to avoid mixing of air masses and prevent mutual cooling or heating of airflows, the air supply and extraction are performed in alternating phases of operation in two interconnected units. 

The Ventoxx Slim Line HRVs 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 is every two years.
