Pure gas

He Helium

It is supplied in cylinders (with a capacity of up to 50 liters and operating pressure of 150/200 bar).

In specific cases, it can be supplied in a special container (with a capacity of 4,400 m³ and operating pressure of 250 bar).

Applications:

Gaseous helium is a versatile gas with unique properties, making it highly sought after in advanced industrial and scientific technologies.
Due to its inert nature and exceptional physical characteristics, helium is used:

in cryogenic systems and high-precision cooling equipment;
as an ideal carrier and shielding gas in gas chromatography and analytical chemistry;
to create a clean, inert atmosphere for welding and metallurgical processes;
in breathing mixtures for medical use and deep-sea diving;
in leak-detection systems that require maximum sensitivity and reliability;
in aerostats, testing equipment, and aerospace technologies;
in the manufacturing of electronics and semiconductors, where gas purity and stability are critical.
