Cryogenic Cylinders
Cryogenic Cylinders
Low temperature Dewar bottle is a kind of high vacuum, multi-layer insulation of the gas cylinder, the outer wall is wrapped with multi-layer insulation material, with super insulation performance, while the sandwich pumped into a high vacuum, forming an excellent insulation system, so that the medium in the bottle to keep low temperature, not affected by the external environment temperature. The inner tank is used to store cryogenic liquids. Commonly used for storage and transportation of liquid nitrogen, liquid oxygen, liquid argon, liquefied carbon dioxide, liquefied nitrous oxide, liquefied natural gas and other low temperature liquids.
Main Features:
- High vacuum multilayer insulation to ensure low evaporation rate；
- The volume of gas cylinders is generally between 80L and 500L；
- Widely used in gas liquefaction, storage and gas, chemical and food transportation industries；
- Built-in carburetor automatically provides stable and continuous gas of 10Nm³/h；
- 3 Year vacuum warranty service；
- Innovative visual level gauge；
- Enhanced side head support；
- The stainless steel support structure between the inner shells is durable;
- Stainless steel neck tube can withstand accidental low-temperature bottle rollover;
- Adsorption material can maintain vacuum for a long time;
- With bladder bursting disc, double protection of bladder safety;
- Equipped with shell release device to protect the safety of the shell；
It is mainly used in the following areas:
- Medical liquid oxygen can be used as a centralized gas supply equipment to make the gas more pure and healthy;
- Can be loaded with high purity industrial liquid oxygen, used for metal cutting, welding, heating and aerobic transportation;
- Can contain liquid nitrogen, used for high purity nitrogen protection or food, medicine, biology and superconducting liquid nitrogen of minus 196℃ cooling carrier.
- Can contain liquid argon, used for argon arc welding and other argon protection occasions;
- Can contain liquid carbon dioxide, used for welding gas protection, can also be used for food freezing or preservation.
- LNG can be used in metal cutting, heating and other places where natural gas can be used
- Nitrous oxide can be used in hospitals for analgesia or anesthesia
