Water-melt-frost system is generally used in the large capacity cold air machine.
It is simple and reliable, has good effect in frost melting, less warehouse temperature rise in frost melting process, especially suitable for fast freezing refrigerating warehouse.
The disadvantage of this water-melt-frost system is that the water used to melt frost should not lower than 15℃,
so this kind of air cooler can’t be adopted by the area of low atmosphere temperature.

Various water-melt-frost unit coolers are provided for selection.
