Troubleshooting solutions for blower inverter module failures
Thread Content
The high-voltage inverter for the chemical plant’s gas blower has been in use for 7 years now, and it often malfunctions, causing problems with the blower. Apart from replacing the entire module, are there any other solutions that can be used to avoid this issue?

It is recommended that, in addition to the issues with the device itself, it is also important to check the controlled devices for problems. There are certain limits to the operating conditions of frequency converters, and this is related to factors such as the load on the motor and the operational load of the fan. Oh, and there’s also the hidden issue of grounding leaks, which are the hardest to detect. For example, I’ve encountered situations where water got into the cable ends.
The balance of the fan impeller, the fasteners, the air valves and dampers within the system – any change at any point in the ventilation circuit can affect the load on the entire system. The frequency converter has a service life of 7 years; with well-known brands, no major problems should arise.
