Product Description

The ‘Swarg Systems & Instruments’ apparatus consists of a transparent glass cylinder at the top of which two condensers hang and steam is admitted at the bottom. One of the condensers is provided with chrome-plated surface for dropwise condensation and other with natural surface finish to promote filmwise condensation. Water is circulated through the condensers from common inlet. The transparent glass cylinder allows visualisation of condensation process. A rotameter measures the water flow and a pressure gauge indicates the steam pressure. A digital temperature indicator measures temperatures at various points. Thus heat transfer coefficients in dropwise and filmwise condensation can be determined.
