EvapCare™ evaporators for efficient vacuum distillation of thermosensitive products
EvapCare is Sulzer’s advanced line of film evaporators, designed for high-purity production from heat-sensitive and complex feedstocks. With low pressure drops, short residence times, and precise temperature control, often under vacuum, EvapCare minimizes thermal degradation and side reactions.
Ideal for viscous, thermally sensitive, or reactive products, EvapCare can be used as standalone units, skid-mounted systems, or as reboilers within DistilCare™ vacuum distillation setups.

EvapCare is Sulzer Chemtech’s specialized service offering for film evaporation processes.
It combines high-performance falling film (EvapCare-F), wiped film (EvapCare-W), and short path (EvapCare-S) evaporators with engineering expertise, pilot testing, and full project support.Customers benefit from comprehensive standard or tailored solutions that maximize product purity, process yield, and operational efficiency, especially for sensitive and complex feeds.
Sulzer film evaporators use thin liquid films flowing across heated surfaces such as inside tubes (EvapCare™-F), on wiped surfaces (EvapCare™-W), or within very short distances between heating and condensing surfaces (EvapCare™-S).
These designs minimize thermal degradation and unwanted reactions, thanks to low pressure drops, short residence times, and precise temperature control, often under vacuum operation.
Mastering the Marangoni effect (surface tension gradients), proprietary liquid along with precision-engineered sleeves further ensure optimal wettability on tube walls, uniform film formation and gentle, efficient evaporation crucial for preventing fouling and minimizing thermal product degradation.
These features preserve the color, taste, aroma, and active ingredients, required in fine chemical, bio-based or pharma markets for instance.
EvapCare serves the chemical, fine chemical, pharmaceutical, food and beverage, biotech, oleochemical, and nutraceutical industries to name a few.
Typical applications include product purification, solvent recovery, concentration of slurries and solutions, degassing, stripping and waste stream reduction.
The technology handles everything from high-purity APIs and edible oils to monomer removal and advanced bioprocessing streams, preserving critical quality features (color, taste, smell) for demanding applications.
EvapCare offers three main film evaporator types: EvapCare™- F Falling film, EvapCare™- W Wiped and, EvapCare™- S Shorth path evaporators.
The optimal evaporator type is determined by your feed characteristics, product goals, and operational needs:
EvapCare™-F: Is best for heat-sensitive, low-viscosity feeds with minimal or moderate fouling risk. It utilizes vertical tubes and a proprietary distribution system to guarantee uniform thin films, high heat transfer, gentle processing, and low pressure drop, making them perfect for large volumes and applications like product concentration, solvent recovery, or gentle purification.
EvapCare™-W: Is ideal for more viscous feeds prone to fouling or requiring particularly short residence times. It employs a mechanical rotor for constant film mixing and minimal buildup, which is critical for processing polymerizing streams, high-boiling or sticky substances, and slurry feeds.
EvapCare™- S: Is perfect for high molecular weight, extremely heat-sensitive or high boiling compounds. It integrates vertical condenser to shorten vapor travel and enable operations at pressures well below 1 mbar, minimizing thermal stress, maximizing product purity, and allowing separation that is unachievable with other designs. It is ideal for APIs, natural extracts, or high-purity specialty chemicals.
Each design is available in standard and customized sizes, materials (including glass-lined), and with application-tailored rotors or sleeves.
Absolutely. Sulzer provides tailored designs, from small laboratory units to large-scale skid-mounted plants, compatible with batch and continuous operations. Through detailed pilot trials and process simulations at Sulzer’s test centers, each evaporator system is optimized for your feedstock, capacity, and product specifications.
EvapCare solutions can be used to revamp, retrofit, or modernize existing evaporator units whether originally supplied by Sulzer or by another manufacturer.
These projects are supported with complete engineering, from feed distribution to automation and GMP compliance. Contact us to identify the key considerations for a successful upgrade and guaranteed process results.
With decades of experience designing and certifying film evaporators according to European, US, and international GMP/CIP standards, Sulzer’s EvapCare delivers end-to-end project support, including feasibility studies, process simulation, pilot trials, mechanical design, 3D skid layout, plant automation, HAZOP, installation supervision, and operator training.
Commissioning is handled by Sulzer process engineers while after-sales services cover spare parts, maintenance, troubleshooting, plant optimization, and revamps ensuring lifelong reliability backed by a wide range of construction materials (stainless steel, glass-lined, exotic alloys, etc.) and guaranteed performance.
Key benefits include higher heat transfer coefficients, lower pressure drop, wider operational range (surface area, tube lengths…), and suitability for vacuum conditions and GMP environments. Short residence times and gentle heating yield higher product purities with minimal degradation. Cost-effective equipment, flexible design features, and proven anti-fouling technology mean lower maintenance and better value over the plant’s lifecycle.
