How to Prevent Condensation in Battery Cabinets
Have you ever wondered how moisture forms inside sealed battery enclosures? Condensation in battery cabinets causes 23% of premature lithium-ion failures according to
For larger or high-power equipment, use forced-air systems like fans or blowers to keep the internal air moving. When the temperature inside drops below the dew point, condensation can form. To prevent this, install heaters, fans, or heat exchangers to keep the air inside at a stable temperature.
Electrical enclosures are easy targets for condensation. They often have warm components inside, but the outside air might be much cooler. When the inside air touches the cooler walls, moisture can form inside the box. Many people think that using a high IP or NEMA rated enclosure will stop this.
They don't stop condensation inside the enclosure. Even sealed enclosures can trap moist air during setup, which later turns into water when the temperature drops. Even a small amount of moisture inside an enclosure can lead to big problems. Unlike a splash of rain or an obvious water leak, condensation builds up quietly.
Corrosion, short-circuiting, diminished performance, dangerous electrical arcs, and expensive down time can all result from just a little bit of condensation in an enclosure over time. So, what is the best way to keep condensation out of a polycarbonate enclosure?
