Browse used, surplus and secondhand evaporators from IPP – in stock and optimized for chemical, pharma and food processing

Save time and money with IPP’s ready-to-ship evaporators for distillation, purification and thermal separation

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.

Primary uses across industries

  • In pharmaceuticals, evaporators concentrate APIs and remove solvents during intermediate processing
  • In chemical manufacturing, they purify products and reclaim valuable solvents from process streams
  • In food and beverage, they concentrate juices, dairy products, extracts and syrups
  • In wastewater treatment, they reduce volume and recover reusable components

Types of materials processed

  • Heat-sensitive or solvent-based mixtures
  • Aqueous solutions, organic solvents and slurries
  • Viscous liquids and high-solid content mixtures

Common materials of construction

Evaporators are built for long service life, cleanability and chemical resistance:

  • Stainless steel for sanitary and corrosion-resistant applications
  • Hastelloy and other alloys for aggressive chemicals
  • Glass-lined steel for ultra-pure or reactive materials

Key features of industrial evaporators

  • Available as single-effect or multi-effect systems for energy efficiency
  • Options for vacuum operation to protect heat-sensitive materials
  • Integration with distillation, crystallization or solvent recovery units
  • Configurable heating sources: steam, hot oil, or electric
  • Designed for clean-in-place (CIP) and automated control systems

Evaporator FAQ

Have questions about Evaporators or our services? Learn more about our products and why customers choose IPP.

What’s the difference between falling film and forced circulation evaporators?
Falling film evaporators are ideal for heat-sensitive materials and lower viscosities, while forced circulation systems handle higher solids and fouling-prone feeds.
Can used evaporators be modified for new applications?
Yes – many units can be reconfigured with new instrumentation, controls or materials of construction to meet changing process needs.
Are multi-effect evaporators more energy efficient?
Absolutely – they reuse vapor from one stage to heat the next, reducing overall steam consumption and operational costs.
What are the benefits of buying used or secondhand process equipment from IPP?
IPP provides faster lead times, cost savings and global support from a team with 47+ years of process plant experience.
