Fire protection is environmental protection

Again and again, devastating fire incidents not only destroy material assets, but also result in considerable damage to nature and to the environment. On the one hand the damage is caused by the fire itself, but on the other hand also by released smoke and gases, fire loads, fire residues and in this context by smoke and soot particles and other pollutants that are released. In addition, there are consequential damages due to the use of non-destructive extinguishing agents to put out fires. For example, extinguishing water can also have an adverse effect on the environment.

In terms of sustainability, environmental protection is becoming increasingly important to companies. Sustainability aspects must therefore be considered from the very beginning when developing individual fire protection solutions. Holistic solutions thus become a formula for success, but not only targeting personal and property protection, but also protecting the environment and the climate in the long term.

Innovative technologies focus on holistic, sustainable fire protection

Fire risks and the associated consequential damage are directly related to installed and stored materials and thus to the substances that are released in the course of a fire incident. For example, released carbon monoxide causes the formation of ground-level ozone, which is harmful to the environment; ammonia and sulfur dioxide impair the quality of the air we breathe and cause acidification of entire ecosystems.

The decision for a fire protection solution is based primarily on the aspects of efficiency and cost, whereby cost is often the driving factor in the course of economic efficiency aspects. Unfortunately, due to a lack of education and knowledge, it is often ignored that the costs of restoring damaged ecosystems as a result of a fire are many times higher than for the use of preventive and thus sustainable fire protection systems.

The better solutions in fire protection are systems that minimize the risk of a fire incident and the resulting consequential environmental damage. This is referred to as fire prevention solutions, which work with the principle of oxygen reduction.

Environmentally friendly extinguishing agents are predominantly used in fire extinguishing today. These include the gaseous extinguishing agent nitrogen (N2). It extinguishes fires in a targeted manner without damaging the protected area and the property located within it. The N2 used in fire protection systems does not contribute to global warming because it is extracted directly from the ambient air and returned to the environment during the extinguishing process. In addition to N2, natural gases such as argon are also used. These so-called inert gases are completely ecologically harmless.

But also the use of long-lasting fire protection systems, which are used sustainably thanks to appropriate maintenance and servicing concepts, contribute to resource conservation and savings. And last but not least, reusable extinguishing agent containers make their contribution to climate and environmental protection.

Our award-winning solutions focus on sustainability and low energy consumption

Climate and environmental protection have a long tradition at our company. Ever since the company was founded in 1976, we have been constantly striving to develop energy-saving and thus environmentally friendly products and systems and to reduce energy consumption ever further. Resource efficiency is a driving factor in the course of our product development cycles as well as in the context of new developments.

In addition, as early as the 1990s, we replaced chemical extinguishing gases for fire extinguishing with natural gases that can be generated from the ambient air. In contrast to chemical gases, they do not form chemical combinations with other substances at high temperatures and therefore extinguish fires completely without leaving any residues. In 1997, we pioneered this technology in Germany by being the first company to introduce nitrogen as an extinguishing gas in a firefighting system. No other company in Germany had used nitrogen in this way before. Since 1998, we have - been using nitrogen for fire prevention. The use of nitrogen in oxygen reduction plants is VdS-certified.

Our goal in product development is to successively reduce the energy requirements of our systems. In recent years, for example, we have been able to achieve significant savings in energy requirements for the generation of one cubic meter of nitrogen for fire prevention. This is made possible by the Vacuum Pressure Swing Adsorption technology (VPSA) which we have further developed. This generates the nitrogen required for oxygen reduction even more efficiently from the ambient air on site. Our vision is to bring the first completely CO2-neutral fire prevention systems to market.

All our systems are scalable and grow with your increasing security requirements. There is no need for unnecessary retrofitting. In addition, we guarantee the long-term use life of our systems thanks to comprehensive maintenance and service concepts. This is also a valuable contribution to environmental protection and helps our customers to achieve their climate targets.

"Our commitment to you: No loss caused by fire - Guaranteed."

Our vision accompanies us in our everyday work as well as in our constant pursuit of perfection. In addition, our innovative, holistic and sustainable solutions make an active contribution to climate and environmental protection.

Products & Systems

Every fire pollutes the environment. That is why our goal is to minimize the risk of a fire starting as much as possible. In 1998, for example, we developed the fire prevention technology now known as OxyReduct®, which works on the principle of oxygen reduction. For this purpose, we reduce the oxygen concentration to a defined protection level by using the inert gas nitrogen in the areas to be protected. In an oxygen-reduced atmosphere, the development of a fire is prevented, or a starting fire can no longer develop.

The risk of a fire event with its devastating consequences for people and the environment, including unintended side effects such as damage caused by smoke and soot particles, released pollutants or contamination by extinguishing water, is reduced to a minimum. For us, this sustainable fire protection principle is called "active fire prevention" and is our contribution to the sustainable protection of people, property and the environment.


The earliest possible fire detection also makes a valuable contribution to detecting fires at a very early stage and preventing further fire development and spreading. Here we rely on the use of optical aspirating smoke detectors with HPLS (High-Power Light Source) technology. Our aspirating smoke detectors can be optimally adapted to the individual requirements of the protected area at any time. They detect even the smallest smoke particles and thus a fire in the formation phase much earlier and without false alarms compared to point detectors.

Compared to other systems, our TITANUS® aspirating smoke detection systems are extremely energy-efficient and have the lowest power consumption. They can be designed modularly for any application so that unnecessary oversizing is avoided. Regular maintenance ensures a long-term use for the products and systems. This saves resources and protects nature and the environment.


Fire extinguishing based on gas extinguishing technology is fire extinguishing without side effects! This is because suitable extinguishing gases can stop incipient fires quickly and reliably without themselves leaving damage and residues on buildings, electrical equipment and goods. For more than 20 years, we have relied primarily on the use of natural gases in fire extinguishing. These so-called inert gases include argon, nitrogen and IG-541. Unlike chemical gases, they do not form chemical compounds with other substances at high temperatures and therefore extinguish completely without leaving residues. Moreover, as a component of the ambient air, they are in principle infinitely available, which ensures rapid refilling and thus sustainable use of the gas extinguishing tanks.
