Product Description

Desert cooler is a cheap means to produce comfort air condition. It has low initial, running and maintenance cost. In the ‘Swarg Systems & Instruments’ apparatus, air flow is generated by an axial flow fan, enclosed in a box. The fan draws air over the khus curtain. Over the curtains water is sprayed by a small pump and sprinkler arrangement. Shutter in front of fan controls air flow. The air gets cooled by evaporative cooling. Various measurements provided enable the students to study the characteristics of a desert cooler at various air and water flow rates.
