Air-cooledheat exchangers have sometimes troubles with heat duty due to lower axial fans performance. Usually it happens due to fan blades disbalancing, high pressure drop of cooler air side or hidden defect of fan design.  

‍

All these troubles are solved by our aerodynamic optimizing which consists of these operations:

• Cooler air side design check
• Fan geometry check
• Fan aerodynamic performance measurement
• Repair of the fans and cooler air side
