Industrial gas.
|
For more than 70 years, DILO has been developing products and systems that enable operators of gas-insulated systems and applications to reliably monitor and analyse the arc quenching and insulating gases as well as other industrial gases used to extract, purify and return them without emissions. This unique combination of expertise, technology, experience and customer orientation makes DILO the world's leading specialist in "Emission-free handling of arc quenching and insulating gases". |
The DILO success story began in 1951, when DILO engineers developed a sealing principle that still enables high pressure tube connections to hermetically seal without any intermediate seals. This patented innovation shaped the future strategic orientation of the company, which from then on positioned itself as a niche specialist for arc quenching and gas-insulated and other industrial gas applications.
Today, DILO is the undisputed technology leader in this field, manufacturing user-friendly system solutions for the emission-free handling of industrial gases at the company's site in Babenhausen/Germany. “ZERO EMISSIONS,” is our guideline. Every DILO solution reflects a commitment to sustainability and customer requirements.
Looking ahead, DILO aims to drive the energy transition and make a measurable contribution to climate protection by continuously expanding research, development, and production capacities and adapting its services to global customer requirements. To achieve this, the company is constantly expanding its research, development and production capacities and continuously adapting its range of services to meet the needs of its customers worldwide.
