Star DC (DRY COOLERS) are close circuit fluid cooler which has hot fluid circulating through the tubes of the coil and air passes over the coil to dissipate heat from the fluid to the atmosphere. The fluid being flowing in closed circuit there is no risk of loss of fluid neither risk of contamination and scaling.
Dry Coolers compared to conventional cooling towers has low cost of running and requires very low maintenance. All it needs is routine cleaning of complete cooler internal external with low pressure compressed air & check-up of electric fan motors.
Since it is Dry cooler and does not need water, added to that it has several advantages by which day by day they are the most preferred especially due to the worldwide water scarcity being a major issue.
