Sulzer launches EvapCare™-F: a breakthrough falling film evaporator for temperature-sensitive products

Sulzer’s new EvapCare™-F redefines the processing of temperature-sensitive materials. This advanced falling film evaporator is the ultimate solution for gently processing temperature-sensitive products, offering unmatched precision and innovation that transforms how manufacturers handle delicate materials.

Innovation meets science: the Marangoni effect

EvapCare™-F leverages surface tension gradients to ensure perfect wettability on the tube surface. This enables even liquid distribution, prevents dry spots, and minimizes product degradation. By harnessing these natural forces, EvapCare™-F maintains product integrity and maximizes efficiency.

Engineered to make your product a success

The system is designed to safeguard the core value of your product. It uses vacuum and short residence times along the heated surface to prevent secondary reactions and preserve organoleptic properties, ensuring taste, smell, and quality remain intact.

Key benefits

• Superior heat transfer performance with high coefficients for reduced investment costs
• Minimal processing time on heated surfaces to prevent degradation
• Low pressure drop for efficient operation
• Deep vacuum capability for the most sensitive applications
• Outstanding fouling resistance for smooth production
• GMP compliance for pharmaceutical and food applications

Versatile across industries

EvapCare™-F is available as standalone equipment, a plug-and-play skid-mounted unit, or integrated as a reboiler in vacuum distillation systems. It is ideal for evaporating, concentrating, recovering, or distilling low-viscosity products with minimal fouling tendencies.

Serving the chemical, petrochemical, and polymer industries, the system delivers reliable performance for applications such as concentrating pharmaceutical compounds, processing specialty chemicals, and handling polymer solutions.

Configurations range from 0.3 to 4800 m², with 4800 m² ranking among the largest EvapCare™-F units ever built worldwide, operating single pass or with recirculation, with co-current or counter-current flow of process vapors and liquid. Multi-stage systems can be combined with wiped film evaporators for complex processing needs, lowering energy use and operating costs.

Precision distribution technology

At the core of EvapCare™-F is a proprietary liquid distribution device that guarantees uniform flow across all tubes. Gravity drives the product as a continuous film along the tube length.

The two-stage distribution system offers high accuracy and a wide operating range, with sizing optimized using Sulzer’s proprietary design tool. This ensures consistent treatment, maximized yield, and product consistency.

Proven track record and future-ready solutions

Sulzer has over 60 years of experience in sizing and manufacturing falling film evaporators, with thousands operating worldwide. To ensure reliable equipment design and verify performance against specifications, Sulzer tests individual processes in pilot plant facilities and offers mobile test equipment on a rental basis for on-site trials.

The bottom line

For manufacturers dealing with temperature-sensitive products, EvapCare™-F is more than new equipment. It represents a competitive advantage by combining gentle processing, energy efficiency, and proven reliability, which makes this technology a strategic investment in product quality and operational excellence. Its flexible design allows it to use process streams as a heating source, reducing reliance on conventional utilities like steam or thermal oil. This flexibility is essential for adapting to diverse production environments and achieving meaningful energy savings while supporting increasingly strict sustainability standards.
