About our company



SEVentilation GmbH was founded in December 2010 by the two engineers and managing directors Dipl.-Wirtsch.-Ing. Nico Schellenberg and Dipl.-Wirtsch.-Ing. Alexander Buchspieß.

The Slogan was:
“In times of rising energy costs, reduce energy costs with high-quality and affordable products”.

As lone fighters, the two managing directors initially started the mission of manufacturing energy-efficient, decentralised ventilation systems with heat recovery on their own. Development and production of the ventilation systems began on a 150m² site in the Kahla industrial estate in eastern Thuringia. The number of employees grew up to 4 members during this phase.

Seventilation on course for growth

After more than 4000 decentralised ventilation systems had already left the premises of SEVentilation in 2013, the move to an 1800m² property with a production and storage area of more than 800m² took place in 2014. In the following years, the capacities were additionally increased by the purchase of an adjacent property with another building and by the construction of a new warehouse, so that now over 1500m² of production and covered storage space are available on a 3000m² property.  Due to our high-quality products and our qualified advice, we have been able to record continuous growth since the company was founded. And we want to continue to inspire our customers with decentralised ventilation systems and grow with them.

The company today

We are a team of employees and partners, some of whom have decades of experience in ventilation technology. Our competences are concentrated at the company headquarters in Kahla. The management, development, production and parts of the regional sales network work at the location in Eastern Thuringia. Due to short communication channels, technical developments, for example, can be advanced quickly and the quality of our products “Made in Germany” can be kept high. Through our numerous sales partners in Germany, we are always close and “on site”  to our customers. In addition, we also have sales partners in Europe and Asia.

Our commitment to your quality

The continuously increasing sales figures confirm and motivate us to constantly develop our products and to continuously build up and expand our product portfolio. We take pleasure, fun and commitment in the development and production of our decentralised ventilation systems with heat recovery every day. SEVentilation GmbH is one of the few companies in the ventilation industry that is still owner-managed. We are very proud of this.

A valuable contribution to living comfort and resource conservation

The new social awareness of sustainable building that has been gained in recent years is an important step on the way to ecologically compatible living. However, the correct implementation of the principles that follow from this also increases individual living comfort and reduces rising costs.

With this in mind, we have set out with our young company to make a valuable contribution to climate regulation in residential and commercial spaces. Our name – Save Energy Ventilation – stands for resource protection, for the highest possible climate comfort and the lowest possible pollution.

High-quality ventilation systems for private and business customers

In green Thuringia, the centre of Germany, we produce ventilation systems that really meet the high demands of our climate- and cost-conscious customers. For maximum quality, our products are subject to strict controls, thus the compliance with the relevant DIN standards is mandatory for us. In order to also ensure the high-quality level of our fans in the future, we are constantly developing our technology and coordinating closely with scientific institutions.

The results of this work are systems that combine the highest levels of air hygiene with ease of operation and energy-saving, unobtrusive functionality. For us, resource protection never works in spite of our customers, but only with them and for them.
