Product Parameters

Design Conditions
Experience remarkable cooling efficiency with our advanced design where the entrance temperature (t1) begins at a notable 37ºC, smoothly transitioning to a leaving temperature (t2) of an optimal 32ºC.
Our cutting-edge cooling tower operates under precise and meticulously calculated conditions, maintaining a wet bulb temperature (tWB) at 28ºC, and achieving a dry bulb temperature (tDB) reaching up to 31.5ºC. All these are maintained while sustaining an atmospheric pressure of P0 = 9.94 x 10^4 Pa. This ensures our tower delivers exceptional cooling performance, irrespective of the environmental challenges it faces, making it a reliable choice for industrial cooling solutions.
