About us
We are heiserTEC – a long-established production site in Kienberg near Gaming, specializing in high-pressure cylinders and systems made of steel.
Our products store, secure, and transport gases – in industry, medicine, mobility, and safety.
What sets us apart is the combination of experience and progress:
200 years of forging tradition meet state-of-the-art manufacturing technology.
Every heiserTEC cylinder is manufactured with the utmost care and in accordance with the strictest international standards.
Our Type 1 steel cylinders are renowned worldwide for their reliability, safety, and durability—manufactured in Kienberg with a passion for precision.
Our high-pressure cylinders and systems are designed for a long service life – built to last for decades.
They are made of high-quality steel, manufactured in an electric arc furnace (EAF) using predominantly recycled material.
This material base not only ensures maximum strength and safety, but also efficient use of resources in production.
The result is technical quality that lasts – robust, precise, and reliable.
We stand for long-term partnerships with customers, suppliers, and employees.
Reliability, trustworthiness, and mutual respect are values that we live by—day in, day out.
At our site in Lower Austria, we develop solutions for tomorrow:
high-pressure systems that store gases, make energy available, and ensure safety.
Our technology is used wherever precision determines performance—in industry, medicine, mobility, and safety.
What drives us is our enthusiasm for technology—and the knowledge that precision creates trust.
Kienberg is our home—and the heart of our production.
This is where history, expertise, and innovative strength come together.
Our employees are the foundation of our success:
experienced specialists and young talents who together continue a tradition that shapes the future.
