High Quality DC Air Cooler Manufacturer and Supplier

Koyer Electric Appliances Co., Ltd. is a China DC air cooler manufacturer and supplier. Our DC air coolers deliver a comprehensive upgrade in performance while establishing a solid foundation of reliable quality, making them an excellent cooling solution for both industrial and civilian scenarios. In terms of performance, the air coolers support 12-speed stepless speed regulation, enabling precise adaptation to cooling needs across different scenarios. Operating at just 60dB in low-speed mode, combined with stable low-voltage startup capability, they are ideal for quiet environments such as bedrooms and offices and can also be directly connected to solar energy storage systems, aligning with low-carbon usage requirements.

In terms of quality, Koyer’s DC air coolers are equipped with multiple intelligent protection mechanisms including overcurrent, overheating, and locked-rotor protection. Every core component and the entire manufacturing process adhere to stringent quality standards, which significantly reduces the risk of subsequent failures and maintenance costs, balancing high-efficiency performance with long-term durability.

1. Can I sleep with this air cooler on?

Absolutely! Our DC solar air cooler is designed for safe all-night operation, making it perfect for bedroom use while you sleep.

2. Is it necessary to pour water in an air cooler?

Yes, water is essential for our DC air cooler to deliver effective cooling—here’s why and how it works: Our air cooler uses the evaporative cooling principle: when water in the water tank comes into contact with the honeycomb cooling pad, the fan draws hot air through the pad. As the water evaporates, it absorbs heat from the air, lowering the temperature by 5-15℃ (varies by ambient conditions) before blowing out cool air. Without water, the unit will only function as a regular fan (blowing room-temperature air) without the evaporative cooling effect.

3. Can you leave an air cooler on all night?

Absolutely! Our solar air cooler is engineered for safe 24/7 operation, so leaving it on all night is completely reliable.
