SustainabilitySustainability

As a leading technology company, we are always focused on the entire life cycle of our products and, of course, the basic production conditions. This is achieved by regularly checking potential resource savings and by avoiding impacts on the environment during production. Every individual employee is asked to make use of the opportunities available to him at his place of work to contribute to further improvements. 

Our products are used throughout the world in a variety of application areas. It is our aspiration to develop and manufacture durable and sustainable products. All Diehl locations worldwide attach the same great importance to energy efficiency and CO2 savings. With best-practice examples we underline the knowledge- and technology-based approach of our efforts. We regularly exchange views and learn from each other throughout the group.

„Free Cooling“ chiller in the data center

Cooling in a data center needs a lot of energy. When modernizing the data center in Röthenbach, care has been taken to install an especially powerful and simultaneously energy-efficient solution.

Modern chillers use the temperature of the ambient air to reduce the energy required for air conditioning of the data center. „Free Cooling“ uses the cold ambient air to reduce the chiller’s cooling power. Thus, the chiller cools itself and needs less energy.

This principle can be used in ambient temperatures below 15°C. In our region, outdoor temperatures frequently are lower, even in summer nights, so that the chiller is highly efficient. When temperatures fall below 5°C, the complete cooling performance is provided by „free cooling“, thus achieving annual power savings of approx. 200.000 kWh.

State-of-the-art cooling

Cooling and heating systems are needed for the air conditioning of production and office buildings to achieve the room temperatures required in the buildings.
In the summertime, the cooling of particular production areas leads to high power consumption at the Laupheim site due to the heat emitted by the machines.

Two cold water chillers cool approx. 85% of the production areas of Diehl Aviation Laupheim. In 2013, the chiller in the production building was completely retrofitted. Facility management installed compressor technology with speed-controlled screw compressors achieving high efficiency. The system at Diehl Laupheim is one of the first reference systems based on that technology, which is in industrial use.
In 2016, another building was equipped with the proven compressor technology.

Future-oriented drive concepts for tomorrow’s automotive industry

The automotive industry is changing. Above all automobile emissions are to be further reduced to achieve climate and environmentally friendly mobility. Diehl Metall as an automotive supplier also supports this progress towards a sustainable driving experience and thus has its finger on the pulse of time. With modern drive concepts, the company helps to shape the mobility of tomorrow.

The portfolio ranges from components for cooling systems or power modules, parts for sensor technology to contact systems for battery storage. Diehl Metall always develops and produces its high-performance products with consideration of resource conservation and downsizing while ensuring a safe and reliable driving experience.

Thus, Diehl Metall makes a decisive contribution to sustainable and CO2-free mobility. If 100,000 electric cars on German roads were substituted for the same number of gasoline-driven cars, 225,000 tons of CO2 could be saved, based on an average CO2 emission of 150 g/km and an annual distance traveled of 15.000 km.

Water meteringWater metering

Smart meters for ecology-minded consumers

Most people know water, gas, electricity and heat meters as devices installed in the basement where they measure the respective amount consumed that is passed on to the water or energy provider. Thus, the occupants know the total amount consumed but do not know when their consumption is particularly high and what to do about it.

Smart meters create transparency: Through an app, customers have easy access to understandable real-time information about their electricity, gas, water or heat consumption. So, they can identify savings potentials and change their consumption behavior. Anyone who takes appropriate measures can save up to 20%.

Diehl Metering produces and markets water, thermal energy, eletricity and gas meters that collect data via a secured system. Data security is of utmost importance. BSI*-conformal system technologies ensure that no personal data are made transparent through the consumption data.
