What is Cryogenic Equipment?
Cryogenic equipment includes an array of devices engineered to manage cryogenic processes. These include:
- Cryogenic tanks and storage vessels
- Heat exchangers
- Cryogenic pumps and compressors
- Dewars (double-walled vacuum containers)
- Valves and transfer lines
- Cryocoolers and refrigeration systems
The purpose of this equipment is to store and transport liquefied gases such as nitrogen, oxygen, argon, natural gas (LNG), and helium safely and efficiently.
According to a Cryogenic Equipment Market report, the industry is expected to grow significantly in the coming years.
Key Applications Across Industries
