Technology and Environment in Harmony

Sustainability in practice
The world is changing and deserves sustainable solutions to the ecological challenges of humanity. Guided by the values of quality, innovation, reliability and flexibility , we rely on healthy growth and sustainable sustainability in all processes and solutions with over 300 employees and 70 representatives in over 80 countries around the world.

One Vision. Zero Emissions.
Bringing technology and the environment in harmony is both a commitment and a challenge - for our employees, partners and customers worldwide. Our motto “One Vision. Zero Emissions. ”Is the basis of our daily activities and is consistently implemented.

Innovation as a factor of success

Process solutions from the idea through to series production
We are dedicated to manufacturing innovative products. We, as a highly innovative company, continually pursue new solutions for practical application. Safety, economic efficiency and ergonomics are our guidelines.

Thorough testing
When stipulating the appropriate component for each application the components and materials are subject to strict material and endurance tests. Everything which is created on the virtual drawing board is carefully assembled with great attention as a prototype and thoroughly tested. Measuring devices and components for measuring instruments for example are tested for functionality in climate cabinets under extreme climatic conditions.

After successful test, the prototype is integrated into the system – for example an SF6 service cart - and is finally tested thoroughly in our test centre.

Customer-orientated troubleshooting
Our engineers and technicians always search for user-friendly solutions perfectly made to fit customer requirements. For development we attach great importance to close collaboration with our customers since user feedback flows directly into our product development. Thus we turn customer problems into practical solutions for professional and emission-free gas handling.

Made in Germany manufacturing

The best quality, flexibility and adherence to delivery dates

We are dedicated to quality and delivery reliability. With this focus in mind we always pursue a strategy with a high level of vertically integrated manufacturing.

Core competence within our company
All key components which require a high production competence are generally manufactured in our company – no matter whether SF6 coupling parts, safety valves or compressor components. Regarding our sub-contractors we only cooperate with companies which meet our quality requirements without any compromises.

'Made in Germany' Quality
Performance oriented flow assembly, continual improvement of the operational procedure and close integration with the development department guarantee high production efficiency. Our integrated quality management ensures excellence in the manufacturing of products which fulfil the requirement of 'Made in Germany' quality.

Flexibility and delivery reliability
The high in-house production ratio provides high flexibility and independence. Therefore even in extreme cases we are able to meet customer requirements quickly.


An integral part of our company philosophy

DILO's motto is top quality right from the start. After all, it is the basis of our success. We do not leave anything to chance. All processes, from market analysis to product development, design, manufacturing, sales, training and service, are integrated in the DILO quality management system. In this way we ensure the high standard of all our products and services.

Continuous improvement (CIP) is part of our quality philosophy and is implemented in practice in many projects. According to the lean approach, administrative and production-related work steps are examined and optimized. Our maxim is no waste!

Environmental and climate protection
With the quality of our products, we bear responsibility for preserving the environment. Because DILO devices prevent the emission of SF 6 gas into the environment and thus contribute to a reduction in greenhouse gases.

Sustainable action is also the guideline for our own environmental policy. The certification according to DIN 14001: 2015 is an obligation for us as a company to permanently improve our environmental performance.

For example, we only use green electricity, and e-mobility has also arrived at the company. An electric car is already in use, and there are also two charging stations for electric cars available to customers and visitors. And all employees who own an e-bike can charge their batteries free of charge on the company's premises.

Water is a precious commodity that we pay special attention to. When washing metal parts, the wash water is reused several times. Only extremely small quantities of water that can no longer be treated are disposed of properly.

DILO. Quality and environment in harmony.
