How to protect inverters against dust and moisture?

This is a question that many engineers are interested in, especially when inverters are installed in environments with dust, humidity, salt air, or corrosive substances. In this article, we will learn how to protect inverters from dust, methods of moisture protection, and the benefits of protecting this equipment. Let’s explore with Song Nguyên to protect your inverter!

In industrial environments, dust and small particles can greatly affect the performance and lifespan of inverters. For inverter manufacturers, they often recommend options such as coated circuit boards (coating board) or protection ratings IP54, IP65, IP66, which all provide good protection. However, these options are quite expensive and may not be practical in urgent situations or when no spare units are available. To protect your equipment effectively, Song Nguyên offers the following solution:

We would like to introduce a convenient, cost-effective, and easy-to-apply solution to protect inverters in harsh environments. This method has been applied by Song Nguyên and has brought excellent results.

That solution is UC–100 Liquid Silicone, used for coating electronic circuit boards. You can easily find this product in local markets or on online platforms such as Alibaba.

Furthermore, when coating the circuit board, you should note the following points:

• Completely disassemble the inverter.

• Do not coat heat dissipation areas.

• Use adhesive tape to cover areas such as power components, ICs, and chips.

• Spray the coating on both sides of the board.

• Apply one layer, then let it dry naturally or use a fan.

• Finally, apply another layer to ensure proper insulation.

Protecting the inverter from moisture is also very important in reducing maintenance costs. Without proper protection, the inverter will wear out quickly due to humidity, resulting in increasing maintenance costs. Storing them in a clean and dry environment can significantly reduce maintenance expenses.

Protecting the inverter not only ensures its longevity and reduces maintenance costs but also keeps the entire system running stably and efficiently. Exposure to dust and moisture can cause malfunctions and reduce inverter performance. Therefore, protecting them will help ensure continuous and stable operation of the whole system.
