the client

The L&T factory in Hazira, Surat is one of the leading turbine blade manufacturers in the country. Employees work all day, regardless of the temperature conditions within the plant. The large workforce of the plant finds it a challenge to work in such extreme temperatures within the factory.

The Challenge

The primary raw material for the manufacturing of turbines is metal. The metal undergoes several heat treatment processes such as hardening, case hardening, annealing, normalizing and tempering. A large amount of heat generated during these processes. Thus, the factory, already situated in a hot climactic region, sees a substantial rise in its interior temperature, causing unrest amongst the on-ground workforce. Installation of air conditioners was not an option because:
The factory is spread over a large area with multiple entry and exit points, making it difficult to have a central air-conditioning solution.
In case of opting for a central air-conditioning solution, the cost of cooling the entire plant was significantly high.
Thus, L&T opted for Symphony’s central air cooling solution.

Highlights

  • Air-cooled 51,000 sq. ft. of a turbine factory to combat massive amounts of heat generation.
  • 15 units of Symphony SPS 30 were installed.
  • Significantly lowered the interior temperature of the factory.
  • Maintained a healthy working environment.
  • Increased employee productivity.
  • Reduced energy consumption and electricity costs.

the Solution

The task to cool a 51,000 sq. ft. turbine factory was undertaken by Symphony. In order to improve the working environment for the workers, experts examined every segment of the factory. Following engineering calculations to provide the best cooling, an optimum solution was provided. 15 units of SPS 30 with top discharge were deployed.
Ducts of various lengths: 15 feet connected to 12 jet diffusers and 120 feet duct with 9 outlets were designed. Since there was a possibility of overhead crane movement inside the unit, the ducts were connected through a plenum structure. Thus, an even distribution of airflow was ensured throughout the factory area. Two-sided cooling pads of the SPS 30 air coolers helped cool the space effectively.

The Results

The factory was successfully air cooled by Symphony and pure, healthy air was disbursed throughout the area. This resulted in improved productivity of the workers, lower power consumption and a cool, healthy working area.
