Have you encountered any of the following issues with your enery equipment

DC electric vehicle charging station

The airflow of rainstorm take into the no protection equipment, resulting in ponding damage and power failure of the cabinet. it brings the high maintenance costs. Moisture condensation cause discharge orcorrosion to the machine

Those power equipment will face those harsh condition influence below

The Challenges of Natural Disasters

Natural disasters pose significant threats to outdoor energy storage and electrical equipment. Typhoons, for instance, can cause widespread damage to infrastructure, with high winds and flyi ng debris damaging protective enclosures and exposing sensitive components to water ingress. Eart hquakes, on the other hand, can shift foundations, disrupting electrical connections and causing physical damage to devices. Prolonged rainfall and flooding can lead to water intrusion, posing the risk of electrical shorts, fires, and accelerated corrosion. Sandstorms, common in arid regions, can abrade protective coatings, infiltrate enclosures, and deposit fine particles that impair ventilation systems and cause overheating

The equipment is facing the trouble of being damaged and difficult to repair at any time

EV charging station needs the air cooling circulation

Air circulation consists of an outlet and inlet.when air passes over or through the vent . The vacuum this creates pulls stale, heat out of the enclosure and then fresh, ambient air is pulled through the inlet vent completing the multiple, daily air exchanges necessary to prevent moisture buildup and mitigate excessive heat for EVSE

Alt: IP55-IP65 internal installation louver with 45% ventilation ratio for cabinet enclosures

Choose the protection level and ventilation ratio you need

Theorem: The higher the protection level comes the low ventilation ratio

We can solve these problems
