STIEBEL ELTRON Introduces VLR 70 S: Fresh Air Ventilation with Energy Recovery for Environmentally Friendly Indoor Air Comfort

With STIEBEL ELTRON’s newest product, indoor air quality is elevated while keeping the electricity bills in check

STIEBEL ELTRON continues to drive environmentally friendly innovation, leading a fresh trend that prioritizes both people and the planet. This commitment is exemplified by the introduction of its latest product, the VLR 70 S decentralized ventilation system with energy recovery.

Presently, the hot, humid outdoor air and severe air pollution make us dependent on air conditioners and air purifiers to create a comfortable indoor atmosphere. Unfortunately, these appliances are unable to decrease carbon dioxide or introduce fresh oxygen into a confined space. High carbon dioxide levels negatively impact sleep quality as well as our cognitive functions. Furthermore, adequate continuous air circulation cannot be guaranteed to prevent moisture build-up and mold growth.

A controlled ventilation system becomes essential to alleviate these shortcomings and to ensure high-quality breathing and long-term health benefits.

STIEBEL ELTRON’s exclusive German innovation is built on an advanced decentralized air exchange system that ensures a continuous supply of clean air and oxygen. The VLR 70 S effectively filters out pollutants such as PM 2.5 and allergens from the incoming air, while extracting volatile substances from the interior to guarantee adequately clean indoor air. Moreover, the system reduces the heat and humidity of the supply air, which significantly reduces the dehumidification load for the air conditioner compared to other systems that do not employ a heat and humidity exchanger.

Whether in the bedroom, home office or in the entire home – odors and moisture should be reliably transported to the outside, while fresh supply air entering the interior should be pre-cooled as well as have its humidity content reduced. The VLR 70 S represents a remarkable advancement in decentralized ventilation technology by employing an innovative aluminium heat exchanger to cool down and to remove up to 50% of the humidity of the incoming supply air. The ventilation units are working in pairs per room, ensuring that the pressure in the room is always balanced. One unit supplies fresh air while the other unit extracts. After 40 seconds the fans reverse direction to allow the heat exchanger to recharge by cooling it down with the extract air.

The VLR 70 S offers lasting satisfaction with high-quality materials and low maintenance. The system requires only a small amount of electricity to operate the highly efficient and low-noise fans with aerodynamical design from Germany. The hygienic aluminium surface of the heat exchanger prevents mold growth and allows for cleaning. The users can easily clean the ventilation system themselves, while the filter replacement process is also straightforward.

STIEBEL ELTRON stands out for its modern and distinctive design. The compact and clean white  decentralized ventilation unit is a perfect fit for all types of accommodations. Featuring a sleek and modern design that seamlessly integrates into any interior, the VLR 70 S does not require ductwork and is therefore suitable for retrofitting or renovation projects.

Every member of the family can bask in the refreshing atmosphere created by the continuous circulation of fresh air. Each breath is fully imbued with a sense of safety and well-being, ensuring a relaxing experience for all.
