1、 Damaged lowering control valve
It is more convenient to reduce the damage and loss rate of the control valve and shorten the length of the connecting pipeline between the gas valve and the instrument.
2、 Uninterrupted gas supply
The centralized gas supply switching system can switch between gas cylinders manually or automatically to ensure continuous gas supply.
3、 Stable gas pressure
The system adopts a two-stage pressure reduction method (level 1 is regulated by the gas supply control system, and level 2 is regulated by the control valve at the point of use) for gas supply, which can have a very stable pressure.
4、 High efficiency
Through the gas supply control system, the gas in the steel cylinder can be fully used to reduce the residual gas and reduce the cost of gas consumption.
5、 Easy to operate
All gas cylinders are concentrated in the same location, reducing handling and installation operations, and saving time and cost.
6、 Reduce the rental of gas cylinders
Adopting a centralized gas supply system can reduce the requirements for the number of gas cylinders, thereby saving the rental cost of gas cylinders.
7、 Reduce molecular sieve loss
Centralized gas supply can better control the purity of the gas (through cleaning and purging), effectively reducing the amount of molecular sieve used (cost saving).
8、 Maintain gas purity
The centralized gas supply switching system is a cylinder gas supply system designed for the supply of laboratory gas (with a leakage rate of 1 * 10-8mbar l/s). Under standard configuration, each cylinder is equipped with a high-pressure purge valve to eliminate impurities introduced during each cylinder replacement, ensuring the purity of the gas at the end of the pipeline.
9、 No gas cylinders in the laboratory
Using a centralized gas supply system means that there are no gas cylinders equipped in the laboratory, which can improve safety. Gas cylinders may fall down and cause damage or injury. It can also improve the sense of safety, as gas cylinders can cause dangerous situations such as gas leakage and fire. It mainly saves space, and removing gas cylinders from the laboratory can free up more experimental space.
