Glass falling film evaporator is a vertical tube evaporation equipment used to concentrate solutions. It is mainly composed of glass tube and shell heat exchanger, glass cyclone separator, glass coil heat exchanger, connecting pipe fittings and other components. All are made of high borosilicate glass with heat resistance, corrosion resistance and excellent performance. It has the characteristics of large unit area, short solution residence time, high evaporation efficiency, clear transparency, corrosion resistance and low concentration cost.
