After using heptafluoropropane for a long time, should I repurchase or test the filling?

Heptafluoropropane fire extinguishing system has reasonable structure and reliable operation, and has been widely used in important places such as computer rooms, archives, program-controlled exchange rooms, television broadcasting centers, financial institutions, and government agencies. In addition, the stability of sevoflurane fire extinguishing agents in sealed cylinders is very good, so the life of sevoflurane fire extinguishing systems is relatively long.

However, after the cylinder has been used for a long time, some customers will have the idea of replacing the system or retesting the filling under normal pressure due to safety considerations. So, when the heptafluoropropane fire extinguishing system is used for more than 5 years, should I choose to repurchase or test the filling?

First, let's look at the test filling of sevoflurane.

Although the heptafluoropropane fire extinguishing system looks very complicated, in fact, the subsequent inspection and filling is not troublesome. Whether it is a pipe network or a cabinet type, the equipment can be disassembled under the guidance of professional manufacturers or technicians, and the steel cylinders and bottle valves The components (including siphons, container valves, etc.) are left to the manufacturer for testing and filling.

In general, if the pressure of the pressure gauge is normal, the cylinder does not have obvious damage or affect the quality of the drug filling, and other components can be used normally after disassembly and cleaning. Most manufacturers will recommend customers to test and fill the sevoflurane fire extinguishing system.

Second, let's see what factors can cause the system to need to be replaced.

One factor is that the pressure gauge is abnormal, and the cylinder and other components are depreciated to a large extent, and the normal use of the system cannot be restored by testing the filling and disassembly and cleaning. In this case, the manufacturer will recommend the customer to replace the system due to security needs.

The two factors are: the pressure gauge is normal (or abnormal), and there is no obvious problem with the cylinder, but the other parts of the system are depreciated, and some important parts have been withdrawn from the market, and the normal fire extinguishing function of the original system cannot be restored. Only new systems can be replaced.

Another factor is that for safety reasons, some local fire inspection departments will require users to inspect, fill and replace the long-lived sevoflurane system. In this case, the cost of detecting filling and replacing parts is not far from the replacement of a new set, and some customers are more inclined to simply replace the new system.

In summary, when the sevoflurane system you purchased has been used for a long time, and it is found in the daily inspection that there is a situation that obviously affects the fire extinguishing function, such as insufficient pressure, you need to contact a professional manufacturer for treatment immediately. If everything is normal, but it is replaced or refilled for safety reasons, you can first contact the fire detection agency for testing, and then determine whether to contact a professional manufacturer for processing.
