Working principle: The inlet air of FBN counter flow type cooling tower is the bottom counter flow.and the saturated warm air is formed with the falling spray water,the heat is discharged from the top air blower,then the water is recycled by the dehydrator with special structure.There is not cooling filler in the Internal space ,so there is more space to increase heat radiation area of every unit. The structure is compact, and the occupation area is small.Especially suitable for low temperature or small temperature difference between the cooling fluids. Usage: The counter flow closed cooling tower has the characteristics of simple structure, compact structure, small occupation area and so on.Especially suitable for low temperature or small temperature difference between the cooling fluids.Such as, medium frequency power supply, 600KW frequency furnace equipment, central air conditioning, compression type refrigerator etc.. Scope of application: Intermediate frequency electric stove,medium frequency induction furnace,central air conditioning absorption type machine,compression absorption type refrigerator,etc. Packaging & Shipping Packaging Details: Normally wood box,it can depend on customers’ requirements. Delivery Details: 25day after receiving order.
