Efficient. Reliable. Engineered for Tomorrow.
The SED Falling Film Tubular Evaporator is an advanced system designed to deliver exceptional evaporation efficiency for heat-sensitive liquids. With superior heat transfer, minimal residence time, and optimized steam utilization, it helps industries achieve maximum concentration with minimum energy input.
Built for precision and sustainability, this technology serves a wide range of sectors - from sugar and dairy to pharmaceuticals and specialty chemicals - setting new benchmarks in process performance.


How It Works
Feed Distribution
Liquid feed enters from the top through serrated distributors, forming a uniform film inside each tube.
Heat Transfer & Evaporation
Steam condenses on the tube’s outer surface, transferring heat to the liquid film inside for rapid evaporation.
Vapor-Liquid Separation
SED’s proprietary UN-MIST™ technology, featuring an embossed plate-type separator, effectively separates vapor and entrained liquid, ensuring clean vapor and higher condensate purity.
Condensate Removal
The vapor is then condensed and recovered, contributing to reduced overall steam consumption in multi-effect systems.
Key Advantages
High Energy Efficiency
Supports multi-effect evaporation at low ΔT, enabling significant steam and energy savings.
Compact and Scalable
Greater heating surface area within a smaller footprint - perfect for space-constrained plants.
Superior Product Quality
Low operating temperature and short retention time protect sensitive compounds from degradation.
Reduced Operating Costs
Optimized heat recovery and minimized steam requirements result in measurable process cost reductions.
Simplified Maintenance
The quick-opening dish end with integrated juice distributor allows faster cleaning and lower downtime.
