From design through to manufacture, COGEMACOUSTIC offers turnkey solutions for ventilating underground works. The wide range of reliable, high performance products include: fans, wet and dry dust scrubbers, flameproof systems, axial smoke-removing fans, and the patented VCI (Sound-proofed Compact Fan).
The VCI (sound-proofed Compact Fan), offers a combination of unique technical and ergonomic advantages
This outstanding product is the result of the research carried out and the technological advances of engineers in mining applications.
Ideal for ventilating mines, gassy or not, and long duration worksites
Jensen Ventilation AB produces and delivers ventilation tubes according to customer requirements for mines, tunnels and other underground work. It uses a welding system that is based on a superior welding method. The method was developed within the company and patented in 1981 in Sweden. The 40 mm wide weld seam becomes almost as strong and durable as the material itself.
Over the years the focus has been placed on being able to produce qualities that cater to different requirements for strength and construction. The result is reflected in today’s qualities JP 501, JP 551, JP 651 and JP 752. All are dimensionally stable, fire retardant and possesses a low coefficient of friction. Anti-static option is also available.
With the help of bends, Y-and T-tubes and reductions, all made from extremely solid fabrics with welded seams, Jensen Ventilation offers a complete and reliable ventilation system.
Three Options for Connecting:
Changes in air speed will result in an alteration of the dynamic pressure, to the disadvantage for efficient ventilation with loss of energy as a consequence. A straighter and tighter tube in the coupling area will lead to better results at the end of the ventilation canal and reduced costs for high kW performance of the fan and reduced operative expenses on account of energy-saving.
