Induced Draft Cooling Towers with Rectangular Appearance
The open circuit cooling towers are devices which make use of a natural principle: a minimum quantity of water dissipates the heat by the forced evaporation to cool down the relevant equipments.

China Efficient Wet Stainless Steel Induce Draft Counter Flow Closed Circuit Cooling Tower
In a closed circuit cooling tower, the tower fluid (water, oil or propylene glycol) is used to provide cooling which is enclosed in a coil and is not exposed directly to the air. The coil serves to isolate the process fluid from the outside air, keeping it clean and contaminate free in a closed loop.Outside of the coil, there is water spraying over the coil and mixes with the outside air to discharge warm air from the cooling tower to the atmosphere as a portion of the water evaporates. Cold water outside of the coil is re-circulated and reused: the cool water loops back to the beginning of the process to absorb more heat during evaporating.
