Air Washer System

DraftAir offerscomprehensive range of Air Washers also known as evaporative cooling system / H (Humidification) Plant,which delivers the best individual solution for process and / or comfort requirements. Our engineering and R&D team focuses on optimization of energy consumption and have createdcomplete Integrated Climate Control (ICC) solutions.

The systems are designed and developed considering all the heat sources in the conditioned area, and required humidity to be maintained constantly at desired levels. However, to control temperature during hot and humid weather, chilled water spray is required & during winter, heating may be necessary.
