The Single Effect Evaporator demonstrates liquid concentration through single-stage evaporation. It allows students to study heat transfer, vapor formation, and mass balance. The setup includes a stainless-steel evaporator, condenser, feed tank, vacuum pump, and control instruments for accurate measurement. Learners can calculate overall heat-transfer coefficients and efficiency. Designed for engineering colleges, polytechnic institutes, and ITIs, it offers safe operation, precise readings, and real-world understanding of evaporation in process industries.
