Frequently Asked Questions (FAQ)

What are the differences between W-SD, W-SL, and W-SJ air coolers?
These series are designed for different cold storage temperature ranges: W-SD is for medium temperatures (-5°C to 5°C), W-SL is for low temperatures (-15°C to -25°C), and W-SJ is for ultra-low/quick-freezing temperatures (-25°C to -40°C).
Why choose water defrosting over electric defrosting?
Water defrosting uses warm water to melt frost, which is generally much more energy-efficient than using electric heating elements. This significantly reduces the overall operating costs of your cold storage.
What mounting configurations are available for these air coolers?
We offer both Ceiling Mounted types (Oblique Side Blow, Standard Side Blow, and Double Side Blow) and Floor Stand types (Standard Top Blow and Vertical Side Blow) to match different cold room layouts.
Can I customize the color and components of the air cooler?
Yes. The steel plate cabinet color can be customized, and we offer optional components such as EBM fan motors, blue hydrophilic aluminum foil, and long-distance air throw cowls.
Which refrigerants are compatible with the W-series air coolers?
The W-series water defrost air coolers are highly compatible with common industrial refrigerants, including R404A, R507A, R22, and more.
