Trust the original. inventer was one of the first suppliers of decentralised ventilation units and can look back on a long-standing tradition of innovation in this field. Much has evolved since then, yet one thing never changes our pursuit of quality, innovation and unrivalled service. Decentralised ventilation units with a 5-year warranty In 1999, inventer developed ventilation technology with ceramic thermal accumulators, which has since established itself as the market standard for decentralised ventilation and is now in use worldwide. Ever since, we have been respected by other manufacturers for the quality of our ventilation systems and valued by loyal customers around the world. ServiceService. Put your trust in inventer with a 5-year manufacturer's warranty. The Schirmer family The important thing for us is that we no longer need to worry about ventilation in our new house. We now have a feel-good climate all the time. The Schrade family Municipal library, Schleiz As a result of a building renovation we now have practically a low-energy house. In these modern buildings, ventilation devices are essential. Our inventer ventilation devices are still running perfectly after more than 10 years. Thomas Haberkern, director of building inspection for the city of Schleiz: We opted for the flexible decentralised ventilation unit from in- VENTer. The ventilation devices are largely concealed inside the walls, making it relatively easy to comply with the rules governing preservation of historic buildings.
Why is ventilation necessary? Controlled home ventilation is important because...... in a modern, energy-efficient house, window ventilation alone is no longer sufficient to ensure the prescribed minimum air exchange (DIN 1946-6). This is due to the high density of the building envelope.... clean and healthy air increases your level of well-being in your own home and your ability to concentrate, and also prevents respiratory diseases.... the constant air exchange prevents mould growth in your living space and ensures that pollutants are automatically removed. Your benefits with inventer No additional piping straightforward installation in the exterior wall Suitable for new buildings and renovations; protects the property through mould prevention Easy cleaning and maintenance Low energy consumption, reduced heating costs thanks to ceramic thermal accumulators Integrated pollen filter for allergy sufferers From the cellar to the roof a solution for every requirement This is how inventer works Ventilation with heat recovery The inventer ventilation system consists of pairs of ventilation units. They always work in push-pull operation. 1 1 The fan in one ventilation unit turns in one direction for 70 seconds and transports the used air to the outside. The ceramic thermal accumulator stores the heat from the air in the interior. Subsequently, the direction of rotation changes. 2 Now the fresh air flows from outside into the interior space. At the same time, the ceramic thermal accumulator uses the stored heat to warm the fresh air. The majority of the heat is retained. inventer thus ensures an optimal feel-good atmosphere. 2

inventer controllers The inventer ventilation units are intuitively operated via matching inventer controllers. Depending on the type of controller, the settings include the ventilation level, various operating modes and our innovative Clust-Air technology (intelligent zone control). MZ-Home Clust-Air - technology for decentralised ventilation systems (inventer zone control) Simultaneous control of up to 16 inventer ventilation devices in up to four zones Individual programming of the weekly timer Diverse functions: heat recovery, ventilation, pause function, connections for CO 2, humidity and temperature sensors Can be integrated into the home automation system smove s4/s8 Touch&Slide controller smove s4: controls up to 4 inventer ventilation devices smove s8: controls up to 8 inventer ventilation devices Can be extended via additional sensors or integrated into the home automation system Integrated hours-run counter Pause function Operating modes: heat recovery, ventilation

Plan your inventer system properly The German Energy Saving Ordinance (EnEV) and DIN 1946-6 standard The EnEV requires that the minimum air exchange volume is ensured ( 6.2). Proof of this is provided by a so-called ventilation concept in accordance with DIN 1946-6. A ventilation concept must be created by anyone making a ventilation-relevant change to an old building or planning a new building. This could be, for example, a specialist commissioned to install new windows or insulate the roof of an older building. For a new building, it is the responsibility of the planners and architects. inventer service centres KfW requirements Energy-efficient construction Our inventer service centres are your ideal port of call for questions about home ventilation. Based on your floor plan, our ventilation planners will create your ventilation concept, including the layout and planning proposal, free of charge. It contains all the important data, which can easily be found at a glance. When the factory data for the inventer ventilation system is entered into the EnEV calculation in combination with a gas condensing boiler, it is often the case that the requirements for a KfW Efficiency House 70 are met and the requirements of the German renewable energy heat act (EEWärmeG) are exceeded.
