Do evaporative air coolers require regular maintenance? How often and how should it be maintained?

Evaporative air coolers require regular maintenance over the long term to ensure efficient operation and extend their lifespan. Daily maintenance includes checking the power and water supply, observing the fan for smooth operation, any unusual sounds or vibrations, and verifying that the control system is functioning properly. These basic checks help identify potential problems and prevent equipment failure.

Weekly maintenance focuses on cleaning or replacing filters to maintain smooth air circulation. Also, inspect the water tank and pump to ensure the water supply system is unobstructed. The wet curtains and cooling media should be inspected and replaced if damaged or excessively worn.

Monthly maintenance involves cleaning the wet curtains and cooling media to ensure they are moist and free of dirt. Check the nozzles and water distribution system for even water distribution. Electrical components should also be inspected for signs of wear or corrosion.

A thorough inspection and cleaning should be performed during seasonal changes or when environmental conditions change to remove accumulated water and dirt to prevent freezing or microbial growth. Furthermore, cooling system settings should be adjusted as needed to accommodate seasonal usage.

A comprehensive performance check is recommended annually, including cooling efficiency, fan performance, and electrical system health. Complex systems are best maintained by professional technicians, including system optimization, performance testing, and troubleshooting, to ensure the equipment is always in optimal working condition.

These regular maintenance measures can effectively improve the operating efficiency of evaporative air coolers, reduce energy consumption, extend their service life, and ensure consistent and stable cooling during hot weather.
