The challenge

Cooling conditions for an underground mine

The world’s second largest producer of zinc has one of their sites in the Rajasthan state of India. The average temperature is 38 degrees Celsius, with regular peaks of 50 degrees – which affects a workforce and their output.

The conditions in the mine were causing concern amongst the workforce, Operations were 1.5km from the surface and fresh air, and the customer needed a solution to help their employees be able to work in comfortable surroundings.

The solution

4,200 kWr cooling brings 50oC temperatures down to 9o

We listened to our customer, which allowed us to comprise a solution that cooled the air in the mine, even 1.5km underground
We delivered 4200 kWr of our mobile, modular bulk air coolers and air handling units, connected with air-cooled screw chillers that were placed on an elevated platform.

This package meant that the air in the mine was cooled to an ambience of 9 degrees Celsius, even in the summer heat.
