Cogemacoustic - Fan Systems and Dust Removal Equipment for Mines

With more than three decades of experience in the ventilation and air treatment of mines, tunnel excavation and other underground works, Cogemacoustic has become one of the most reputed suppliers of dedicated fan systems and dust-removal equipment in the world.

The reasons for Cogemacoustic’s success are manifold. The company provides well-adapted solutions through its precision in the assessment of project needs. This, together with a wide range of products allows the company to propose particularly fitting responses to almost all customer requirements.

Cogemacoustic provides:

• Economic and silent installations – through the use of frequency inverter equipped electrical cabinets, significant power savings may be realised (25%). The modular construction of our fan/silencer units yields exceptional performances at low noise levels
• Robust and reliable products – full electrical, aerodynamic, vibratory and acoustic tests are systematically carried out on all dispatched products, on-site testing and customer feedback are used to develop and improve product quality and performance

AXIAL FANS FOR MINES

Cogemacoustic manufactures energy efficient fans for mining applications. As a result of innovative design, the company's fans are capable of supplying a higher airflow/absorbed power ratio than equivalent conventional axial fans.

Cogemacoustic's standard range of fans is capable of supplying airflow of 5m³/s to 230m³/s (11,000cfm - 500,000cfm) at a working pressure of 250Pa to 7,000Pa (1in – 28in w.g.) per stage. Comprised of one, two or three stage configurations, Cogemacoustic offers varying levels of sound insulation, enabling customers to find the just balance between budget and environmental requirements.

The mounting of auxiliary components such as inlet bells, outlet cones or duct storage cartridges is facilitated by the modular and normalised design of the components (ISO 6580-1981(F) compliant).

A wide range of ventilation characteristics for a given nominal diameter of fan are attained through the application of advanced engineering in the optimisation of the impeller hub diameter in conjunction with the number and length of the blades. The blades are easily adjusted once the fan is at standstill.

COMPACT FANS

For installations in particularly narrow mine conditions, Cogemacoustic proposes a range of extra-compact fan and silencer assemblies. The reduced envelope of these units is the result of an innovative design in which a single all-encompassing cast iron fan body houses the rotor-stator components of the motor, thus eliminating the cumbersome motor casing. These compact insulated fans, which incorporate a pod type silencer, are outstandingly silent and robust.

DRY DE-DUSTING UNITS FOR MINES

In addition to these core products, Cogemacoustic also caters for atypical or extreme customer needs. ATEX certified flameproof fans for coal mines, reversible jet fans for open tunnels and wet and dry de-dusting units are amongst the solutions offered by Cogemacoustic.

MINE VENTILATION DESIGN SOFTWARE

Cogemacoustic engineers and technicians have a great deal of expertise and experience in the field of temporary and permanent ventilation of underground works and mines. The exactitude of their project studies is enhanced by the use of dedicated software, which is either of commercial origin or developed in-house. Such software is used for aerodynamic simulations, mechanical and electrical conception, fan dimensioning and PLC programming.

MINE VENTILATION SYSTEMS

The company’s already extensive know-how in the domain of ventilation has recently been reinforced by the recruitment of new expertise within the engineering team. In this way, Cogemacoustic is in the process of expanding its range of ventilation related products and is currently exploring new and exciting markets.

Cogemacoustic offers customer oriented design. A flexible approach to production procedures together with close collaboration with suppliers allows the company to adapt its standard range to meet specific customer needs (explosion-proofing, installation constraints, etc.) or to produce tailor-made one-off installations.
