FAQ
What is liquid nitrogen and what is it used for?
Liquid nitrogen (LN₂) is an inert gas that becomes liquid at −196°C. It is widely used for cooling, rapid freezing, biological material preservation, cryotherapy, and various industrial processes.
How is liquid nitrogen produced?
It is produced through the air separation process (ASU), where air is compressed, cooled, and distilled to separate nitrogen as a cryogenic liquid.
How is liquid nitrogen stored and transported?
It is stored in vacuum-insulated tanks (VIT) and transported in cryogenic tanker trucks.
How is liquid nitrogen converted to gas?
Through a vaporizer, using ambient heat or an electric heater.
How dangerous is liquid nitrogen?
Direct contact causes severe frostbite, and in closed spaces it can displace oxygen, creating suffocation risks.
What standards apply to liquid nitrogen systems?
ISO 21029, EN 13458, and EIGA 70/17 for safe design, construction, and operation.
Does ParsiaGas provide installation and commissioning services?
Yes. Design, installation, commissioning, and operator training are provided by the technical team.
How long does delivery of the tank take?
Depending on capacity, typically 3 to 7 business days.
