Kraft Power Con India Limited manufactures high-voltage rectifier transformers in Pune. Its manufacturing process faced temperature-related problems due to dust particles. The company installed Symphony Industrial Coolers, which not only control the temperature but also require significantly less maintenance and are more affordable than conventional air-conditioning systems. As a result, the manufacturing process improved, product quality increased and operational costs decreased.

What Were the Heat and Dust Problems in Kraft Power Con’s High-Voltage Transformer Manufacturing Facility?
Kraft Power Con India Limited is a prestigious company that manufactures high-voltage rectifier transformers. Its manufacturing process is highly sensitive because transformers handle high electrical power.
According to Production Manager Mr Vijay Patil, the company faced three major challenges on its shop floor:
Dust entering through doors and shutters: Every time workers moved in and out or raw materials/finished goods were transported, dust from the outside environment entered the shop floor.
Risk of dust on high-voltage equipment: During the manufacturing of transformers and control panels, dust accumulation could cause insulation failure and short circuits.
Decline in employee productivity due to heat: During Maharashtra’s intense summer heat, the temperature on the shop floor became unbearable, increasing employee breakdown time and affecting production efficiency.
Limitations of Conventional Solutions
Air-conditioning systems were extremely expensive and energy-intensive for this environment. Ordinary exhaust fans could draw even more dust inside while extracting air. Ceiling fans only circulated the air but were not effective in controlling dust. Therefore, the engineering team was looking for an innovative, affordable and effective solution.
Technical Approach
Mr Vijay Patil and his team selected Positive Pressure Ventilation (PPV) technology for dust control. Under this technology, the air pressure inside the shop floor is maintained at a higher level than the air pressure outside, naturally preventing external dust from entering.
This is the same principle used in pharmaceutical cleanrooms, electronics manufacturing facilities and data centres. Kraft Power Con successfully implemented it on its industrial shop floor with the help of Symphony Coolers.
Selection of Symphony Industrial Coolers
Six Symphony Industrial Air Coolers were strategically installed across the shop floor. These coolers continuously pump fresh, filtered air inside, due to which:
- The air pressure inside the shop floor remains higher than the outside air pressure.
- Even when doors and shutters are opened, dust cannot enter because the airflow remains directed outwards.
- The temperature remains controlled and employees receive cool, clean air.
- Evaporative cooling technology consumes up to 80% less energy than air conditioners.

Achievement of a Dustproof Environment
After the installation of Symphony Coolers, positive air pressure was successfully established on the shop floor. Dust entering through doors and shutters was minimised. This was the company’s most fundamental and essential requirement, which has now been fulfilled.
Improvement in Employee Health and Productivity
During the summer season, the breakdown time-when employees had to stop working and rest-was previously very high. It has now been reduced considerably. In a cool and clean environment, employees can work efficiently for longer periods.
Healthy Working Environment
Healthy and fresh air continuously circulates across the shop floor. The risk of dust-related respiratory problems has been reduced. Employees are satisfied and the working environment has improved.

Client Feedback
“We have been able to provide a dustproof environment here in our shop. People do not face any problems. During the summer season, due to the intense heat, people’s breakdown time used to increase significantly. It also affected people’s efficiency. That impact has now been reduced considerably. A healthy air atmosphere is always maintained throughout the shop because of Symphony. They are working very well.”
