Cylinders Holding is a Czech company that has been manufacturing pressurised cylinders continuously for more than 120 years. After massive investments, it is the world's largest manufacturer with the largest share of the European steel cylinder market. The company exports to all continents. In selected areas, the holding company is not only expanding its market position, but also building new production facilities.

The company has developed considerably thanks to its current owners. It has specialised technology for the production of pressure vessels for hydrogen and industrial gases as well as atypical pressure systems for hydraulic applications. Cylinders Holding builds on development. In 2008, the company developed and built a new technology for the production of cylinders with a diameter of up to 406 mm using the reverse extrusion process. It is a unique technology, even on a global scale.

Proof of origin for our electricity supply

For our accounting electricity consumption at the Apolda site, proof of origin from renewable energy sources was obtained and evaluated for the years 2024 and 2025. Scholt Energy issued us the „Guaranteed Green“ certificate, including the corresponding proof of origin and evaluation certificates.

The proofs relate exclusively to our electricity supply and do not constitute an indication of CO₂-neutral production or CO₂-neutral products.

In addition, we operate our own photovoltaic systems for electricity generation at the Apolda site.

Our environmental management system is certified according to ISO 14001, and our energy management system is certified according to ISO 50001. With these management systems, we record and process relevant environmental and energy aspects of our site.

27.06.2024 - Cylinders Holding

Cylinders Holding a.s., the world's largest manufacturer of high-pressure steel cylinders and pressurised gas storage and transport solutions, has completed the acquisition of 100 % of the shares in eurocylinders systems AG (ECS), a German cylinder manufacturer. The seller of the ECS shares is the German industrial group Serafin, based in Munich. The buyers are Cylinders Holding and Vítkovice Milmet. The parties agree that the terms of the transaction will be kept confidential.

Jan Světlík, CEO of Cylinders Holding, said: "Our aim was to acquire a good, stable company with growth potential not only in the strong German market, which is eight times larger than the Czech market. At the same time, the company will become an important distribution centre for the Group's entire product portfolio."

Michael Dathe, CEO of ECS, says: "The strategic partnership between two companies that have known each other for many years and whose product ranges complement each other has various advantages and potential. We look forward to working with you in the future."

Cylinders Holding is interested in the long-term development of ECS and will work closely with the current ECS Director Dathe and his team to realise the planned strategy.

The arrival of the new owner will give ECS access to other technologies developed at Cylinders Holding, such as for the transport and storage of hydrogen. ECS will continue to operate as a Cylinders Holding Group company with its own brand and production and will continue its growth as a specialist in high-pressure steel cylinders.

Our hydrogen project

The research project investigates high-pressure containers for the decentralized storage and transport of hydrogen.

The focus is on concepts that are geared towards a lower material input and a higher storage capacity per container. The project is intended to contribute to the development of decentralized transport and storage solutions for hydrogen.

The aim of the project is the development of a high-pressure steel container for the storage and transport of hydrogen. Based on currently customary pressure levels of 300 bar, a high-pressure steel container for an operating pressure of 500 bar is to be developed. The focus of the development is on the material used and the storage capacity per container.

Our photovoltaic system

Since 2023, we have been operating or constructing a photovoltaic system on the roofs of our Apolda location. The system has an installed output of 1,608 kWp and generates electricity from solar energy, which is partially used directly at the site for our production processes.

Modern photovoltaic modules have a long lifespan. After their end of life, the modules should be disposed of in accordance with applicable legal requirements and undergo proper recycling. The recycling of individual module components can reduce the need for primary raw materials. The nature and extent of this process depend on the specific recycling method.

We want to use the energy generated by the photovoltaic system as completely as possible for our production processes at the Apolda site.
