Used evaporators are thermal separation systems that concentrate solutions, recover solvents, or reduce waste volume by vaporizing liquid components. These systems are essential across industries where product purity, yield, and cost-efficiency matter. With more than 47 years of industry expertise, IPP offers used, secondhand and surplus evaporators from 20 complete plant sites and a massive inventory of over 15,000 systems ready to ship.
Evaporators are available in multiple configurations—falling film, rising film, forced circulation, wiped film and multiple-effect systems—each tailored for specific viscosity, temperature sensitivity and throughput needs.
Evaporators are built for long service life, cleanability and chemical resistance:
