Used Colt Products:
VAL is one of the world's premier alumina refining complexes in terms of its technology, human resources and high quality infrastructure. VAL has built a high calibre team which is enabling the company to grow and operate efficiently.
At Jharsuguda, VAL is also setting up an Aluminium Smelter, a Captive Power Plant and an Independent Power Plant. Jharsuguda is situated in the western part of Orissa.
Details of the project:
- 1.75 MTPA aluminium smelter.
- 5x135 MW captive power plant.
- 4x600 MW independent power plants.
- Rail infrastructure for coal, aluminium & finished product.
- A modern township under construction.
Technical requirements
Colt ventilation systems have to be able to operate in sometimes challenging environments around the world.

For the Vedanta Jharsuguda site:
- The ambient temperature can reach 50șC.
- The wind speed can be as high as 145 km/h.
- Defence against 200 mm/h of rain during the monsoon is required.
Colt carried out a survey and technical calculations, and proposed a scheme of Colt Labyrinth gravity ventilators. Each of the eight potrooms with a length of 1,200m will be equipped with a 9m wide Labyrinth unit.
Also all other buildings, anode bake, cast house and work shops are equipped with Colt Labyrinths.
This type of Labyrinth has been specially developed to meet the requirements of smelters.
Features of the Labyrinth ventilator:
- Made of lightweight aluminium
- High performance
- Corrosion resistant
- Maintenance free
- Able to operate despite high quantities of atmospheric dust.
