Voltas has three modern manufacturing plants for HVAC&R equipment, located at: Thane (outside Mumbai), Dadra (Union Territory), and Pantnagar (Uttaranchal).


Product engineering
Voltas has a very strong product engineering base, with an expert corps of engineers designing and developing new products while improving existing ones.

Their approach of intelligent innovation and customized problem-solving is given full play through use of advanced design software. This includes specialized software for coil designing, digital draughtsmanship, solid modelling and simulation.

To facilitate mass production of packaged and split units, and various types of chiller packages, well laid-out conveyorized assembly lines are utilized.

Component manufacturing
The core strength of Voltas manufacturing is its ability to craft high-precision components of considerable complexity, with state-of-the-art equipment and processes.

Installed manufacturing machinery includes CNC horizontal machining centres and turning centres, and Fanuc tape drills.

Coil manufacturing with aluminium fins and copper tubes utilizes

• Fin press and hair-pin benders
• Vertical and horizontal expanders
• Automatic coil brazing machine

This results in coils of the highest quality, offering various options such as louvered fins, slit fins, sine wave and corrugation.

Vapour Absorption Machine manufacturing
Voltas' manufacturing set-up at Thane has modern fabrication facilities with Tungsten Inert Gas (TIG) welding, controlled tube expanding automatic machines, tube finning machines and CNC drilling machines, among others. High precision helium leak testing machines and electronic leak testing machines carry out stringent leak tests on entire VAM machines for passing in the order lower than 1x10-5atm/0 cc.
