Cofimco is the world's leading manufacturer of pultruded aluminum fans and a leader in the fiberglass fan field. Thanks to the innovation inspired by aviation technology, we've reached an efficiency never seen before.
Founded in 1975, with the objective of introducing an innovative axial fan to a sophisticated and more demanding market. Fan sizes are offered ranging in diameters from 3 ft to 40 ft and are suitable for almost any application, including the most demanding ones.
Series B (“Flexi blade”) adjustable pitch fans are available in diameters from 5ft up to 20 ft (6.7 m) in 8 different blade profiles. Both clockwise and counterclockwise configurations are available in standard and reverse mounting types. The flexible connection between the blades (either extruded aluminum or pultruded FRP) and hub is made using a special high tensile steel element.
The COFIMCO-TANDEM® patented and trademarked design has revolutionized the fan industry. TANDEM® blade is the combination of 2 airfoils held together with special tip and root caps. The main feature is the creation of a low-pressure area which delays the separation of the flow around the airfoil. TANDEM® Blade is available in three options, 20TD, 30TD, 40TD, ranging in diameter from 8 to 34 ft.
35F / 35FD blade with FRP pultruded shaft is ideally suited to wet applications with VFD device. It combines the unique advantages of flexible design and high resistance against corrosion. A special root cap design delivers total efficiency increases by reducing reverse airflow effects allowing better flow distribution along the blade.
The 60F and 50F profiles were introduced to offer a very low noise fan with high efficiency for Air Cooled Condenser and Cooling Tower applications. Compared with standard fiberglass blades for 60F and 50F, the largest monolithic pultruded blade ever produced, allows up to 10 dB(A) noise reduction while maintaining extremely high efficiency. 50F and 60F are available in diameter from 14 ft to 40 ft.
Cofimco Cooling Towers are used for industrial processes and in power plants. G and AX fan series in FRP are typically applied in wet and aggressive environments in Cooling Towers. Fan diameters range from 16' to 40'.
Package Cooling Towers
Cofimco Package Cooling Towers are mainly used in HVAC applications. Produced in both FRP and aluminum, the M and B fan series ranges in diameter from 4' to 18'. The CX series fan is offered for low noise applications.
Are a main component in power plants and typically designed with large diameter fans (20' to 36'). Cofimco's G and AX fans are available in FRP and aluminum and with clockwise and counterclockwise configurations and standard and reverse mounting types. Advanced design enables operators to easily adjust blade pitch and maximum travel.
Air Cooled Heat Exchangers
ACHXs are primarily used in industries such as petrochemical, oil refining and gas compression. The Cofimco B series flex fan is most suited for this application and available in FRP and aluminum with diameters ranging from 3' to 18'. Auto variable pitched fans are available when airflow control is required, while for ultra low noise applications CX fans are recommended.
2000 Days without injuries!
Thanks to the commitment of its 71 employees, Cofimco Axial Fans has reached a great milestone: 2000 days with no accidents at work!
ISO 45001 Certification
We are proud to announce that TUV has renewed Cofimco's ISO 45001:2018 certification.
New 38' Diameter Test Rig
Our newly commissioned 38’ diameter test rig is the largest in the market for full scale fan performance, noise and mechanical tests. Parameters including airflow, static pressure, absorbed power, vibrations, stresses, wind conditions and noise can be executed in real time and in accordance with different international standards.
Research & Development
The Cofimco blade design is the result of extensive research and analysis resulting in high performing and efficient axial fans. Constant research for new solutions and enhancement to the current product line is realized through continuous improvement efforts. Thanks to improved FEM analysis and CFD simulations, the Cofimco blade design is optimized from both a structural and aerodynamic point of view, helping to provide customized solutions for different market requirements.
Scaled fan models are tested in two wind tunnels (1250mm/48" and 2000mm/78" diameters) using British Standard fan test procedure BS 848. The fan curve characteristic to predict fan performance is generated from this data. Two test rigs (suitable for 4'-6' and 9'-14' fan diameter) are then used to verify the fan operative curves on actual units. This also allows us to determine the influence of variables such as tip clearance, aerodynamic disturbances and inlet shape. Sound tests are performed in accordance to DIN 45635 standard.
Cofimco's test lab is equipped with the latest and most advanced equipment to perform the necessary test required for research and development. This capability also enhances our field surveys and aftermarket services.
All Cofimco fan models are evaluated under simulated extreme working conditions. Fan blades are checked on fatigue machines and vibration benches in our test lab to ensure an infinite life span for fan components. The most critical blade sections and hub are continuously monitored by strain gauge systems and compared to theoretical values from structural analysis.
Our "FanTastic" selection software (based on project specific requirements) generates optimized fan selections. This software, developed by Cofimco's engineering, provides all fan performance details: characteristic sheet, operating curves, multiple noise evaluation are only a few examples of the software's capabilities.
Some of the world's biggest companies trust us for their business.
