Cooling coil industries presents dry fluid coolers, commonly known as air cooled heat exchangers or dry type cooling towers. These coolers are mainly used for dg set engine water-cooling. The major advantage of these type of coolers are, it needs less amount of water for running the system and very low maintenance. The principle of operation is based on cooling by forced air over finned tube heat exchangers. The cooler efficiency is better when the temperature difference is very high. It is more suitable for water based cooling mainly for dg set and quench oil cooling. Though the initial cost is high, the operating cost is very low. There by the payback period is very short. Cooling coil industries offer various range and capacities to suit any user requirement.
