MANUFACTURING FACILITY AND CAPABILITIES
The NADI Airtechnics production facility is located in the coastal town of Chennai in South India about 12 km away from the heart of the city. The factory has a covered area of 60,000 sq. ft. and additional uncovered area of 25,000 sq. ft.
There are two production units; one unit is exclusively for axial fans and special fans for the railroad and marine applications while the manufacture of large centrifugal fans is done at the other unit.
The fans are manufactured using equipment incorporating the latest European and American technology. Some of the machinery available are:
Flow Forming Technology – CNC Spinning Machine:
Metal spinning, also known as chip-less spinning, flow forming technology, spin forming or spinning, is a metal working process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. Spinning can be performed by hand or by using a CNC lathe or special purpose machines.
Metal spinning ranges from an artisan’s specialty to the most advantageous way to form round metal parts for commercial applications. Artisans use the process to produce architectural detail, specialty lighting, decorative household goods and urns. Commercial applications include rocket nose cones, cookware, gas cylinders, brass instrument bells, and public waste receptacles. Virtually any ductile metal can be formed, from aluminum or stainless steel, to high-strength, high-temperature alloys. The diameter and depth of the formed parts are limited only by the size of the equipment available.
We are equipped with a state of the art, CNC controlled spinning machine imported from Germany, a first of its kind in India.
We have capability to spin blanks up to 2.10 meter in diameter with the thickness of the material as follows:
|Mild Steel||~8 mm|
|Stainless Steel||~6 mm|
This CNC spinning machine ensures that the cones used on our fans are spun to tight tolerances which ensures that the fans perform as per their specifications.
Popular products that can be manufactured are
* Ventilator components-fan inlet rings, fan inlet cones
* Wind generator caps/cones
* Propeller hoods
* Tank bottoms
* Container ends, tank ends, compressor tank ends
* Seamless Funnels cones
* High bay fitting reflectors
* Parabolic mirrors

High Definition CNC Plasma Burn Table:
The material used for the components of our fans are cut using a High Definition CNC Plasma Burn Table that is highly accurate having precise tolerances. This machine has a capacity of cutting steel sheets up to a thickness of 34 mm and stainless steel sheets up to a thickness 25 mm.
CNC Sheet Rolling Machine:
The housings of our axial fans are rolled on a CNC sheet rolling machine incorporating European technology which ensures that there is a tight tolerance during manufacture.
CNC Flanging and Punching Machine:
The flanges of our axial fans are produced on a CNC machine that also punches the mounting holes. This ensures that there is a tight tolerance not only in our flanges but also on the PCD of the mounting holes.
