The difference between liquid nitrogen protective clothing with backpack and without backpack

The difference between liquid nitrogen protective clothing with backpack and without backpack is mainly reflected in the following aspects:

1. Design and wearing convenience

Liquid nitrogen protective clothing with backpack: usually adopts backpack design, which is convenient for wearing positive pressure air respirator and provides more comprehensive respiratory protection for the wearer. The existence of backpack may make the overall wearing process more complicated, but it increases the carrying capacity of additional equipment and breathing support.

Liquid nitrogen protective clothing without backpack: The design is simpler and there is no backpack restraint, which makes it faster and more convenient to wear. This design is more suitable for low-temperature working environments that do not require additional respiratory support or equipment carrying.

2. Function and application scenarios

Liquid nitrogen protective clothing with backpack: Because it is equipped with a backpack and possible respiratory support equipment, this protective clothing is more suitable for scenes that require long-term operation in extremely low temperature environments and have high requirements for respiratory safety. Such as liquefied gas filling stations, freezers, low-temperature environments and oxygen-deficient environments where harmful gases exist (hydrogen sulfide, carbon monoxide, ammonia, methane, propane, liquefied petroleum gas, argon -180℃, carbon dioxide -78℃), emergency rescue and rescue work.

Note: When it is necessary to wear it for a long time in a low-temperature space, it is recommended to use a backpack model with an air respirator at the same time. The general working time can be maintained at about 45 minutes.

Liquid nitrogen protective clothing without a backpack: Although it also has the ability to resist extremely low temperatures, due to its simple design, it is more suitable for low-temperature working environments for a short time or without additional respiratory support. This protective clothing is light and flexible, easy to wear and remove.

3. Comfort and flexibility

Liquid nitrogen protective clothing with a backpack: Although it provides more comprehensive protection, the backpack and possible breathing equipment may increase the overall weight and volume, which will have a certain impact on the wearer's comfort and flexibility.

Liquid nitrogen protective clothing without a backpack: Due to its simple design and light weight, the wearer can move and operate more flexibly in a low-temperature environment. At the same time, its comfort is relatively high, reducing the discomfort caused by long-term wearing.

4. Price and cost

Generally speaking, liquid nitrogen protective clothing with backpacks may be more expensive than models without backpacks due to their more complex design and more comprehensive functions. However, the specific price needs to be considered comprehensively based on factors such as brand, material, and craftsmanship.

In summary, the difference between liquid nitrogen protective clothing with backpacks and without backpacks is mainly reflected in design and wearing convenience, function and application scenarios, comfort and flexibility, price and cost. When choosing, comprehensive consideration should be made based on the specific working environment and needs.
