Laboratory Central Gas Supply System Knowledge

Currently, with the increasing number of laboratory instruments, the placement of gas cylinders has become a major issue. It is neither safe nor aesthetically pleasing in the room, and it is very crowded. In buildings without elevators, the management of cylinders in high-level laboratories is also a major concern.

Laboratory centralized gas supply terminal

In this case, the all-steel test bench gave rise to a laboratory gas pipeline project. The gas cylinders can be placed in a safe and convenient location, and various gases can enter each room through air channels. The gas flow meter's switch valve, pressure gauge, regulator valve, and control box can be installed indoors as needed. It is safe, convenient, aesthetically pleasing, and space-saving.

In the design and installation of laboratory gas pipeline systems, it is recommended that steel-wood laboratory workbenches adopt a centralized gas supply method for delivering high-purity gases, with the following specific advantages:

1 Maintained Gas Purity

Special gas cylinders are equipped with purge valves to eliminate impurities introduced during each cylinder replacement and ensure the gas purity at the pipeline terminal.

2 Continuous Gas Supply

The pneumatic control system enables manual or automatic cylinder switching, guaranteeing uninterrupted gas supply.

3 Low Pressure Alarm

When the gas pressure drops below the alarm threshold, the alarm device is automatically activated.

4 Pressure Stability

The system employs two-stage pressure reduction (the first stage regulated by the gas supply control system, and the second stage by the control valve at the point of use) to achieve highly stable pressure output.

5 High Efficiency

The gas supply control system maximizes the utilization of gas within cylinders, reducing residual gas and lowering gas costs.

6 Easy Operation

All gas cylinders are centralized in a single location, minimizing operational and installation efforts while saving time and costs.

7 Reduced Cylinder Rental Costs

The centralized gas supply system reduces the number of required cylinders, thereby saving expenses related to cylinder rental and purchase.

8 No Cylinders in the Laboratory

The adoption of a laboratory gas pipeline system eliminates the need for on-site gas cylinders, offering the following benefits:

Enhanced safety: Gas cylinders pose risks such as gas leakage, fire hazards, and potential damage from tipping, which threaten the safety of operators.

Increased workspace: Removing cylinders from the laboratory frees up additional space for experiments.

Advantages of Centralized Gas Supply:

1 Guaranteed Gas Purity

Ensures the high purity of delivered gases without contamination.

2 Uninterrupted Gas Supply

Dual-cylinder automatic switching realizes continuous and reliable gas supply.

3 Pressure Alarm Function

Triggers timely alarms when negative pressure occurs in sealed equipment or gas delivery pressure deviates from the preset warning range.

4 Stepwise Pressure Reduction

Adopts primary and secondary pressure reduction to precisely reduce high inlet pressure to the required working pressure, ensuring stable gas usage.

5 Leakage Alarm & Emergency Shutdown

Immediately activates alarms and emergency shutdown procedures upon detecting gas leaks in storage equipment or pipelines, safeguarding personnel, equipment, and instruments.

6 High Operational Efficiency

Centralized storage and management of gas cylinders in a dedicated cylinder room enable efficient operation and convenient cylinder replacement.

7 Maximized Space Utilization

Eliminates on-site cylinder storage in laboratories, freeing up valuable workspace for optimal utilization.

8 Efficient Remote Management

Centralized cylinder management supports remote control and monitoring of the entire gas supply system, enhancing operational efficiency.
