Efficient. Reliable. Engineered for Intelligent Condensation.
SED’s Spray Condenser System is a state-of-the-art vacuum-generating condenser that utilizes the kinetic energy of a motive fluid - typically cooling water or high-pressure steam - to create and sustain vacuum conditions in industrial processes. Designed with precision-engineered nozzles and co-current flow architecture, it achieves rapid vapor condensation, high air evacuation efficiency, and seamless operation even in demanding process environments.
With over 6,600 installations across 39 countries, SED’s patented spray condenser technology has become the trusted choice of leading sugar, chemical, and power industries worldwide.
How It Works
The SED Spray Condenser functions by converting the kinetic energy of high-velocity motive fluid into a powerful entrainment mechanism for vapor and gases:
Spray Initiation
Cold water is pumped into a spray box fitted with precision spray and jet nozzles that atomize the stream into fine droplets.
Co-current Mixing & Condensation
Vapors and non-condensable gases (NCGs) are absorbed during co-current mixing with the cooling water droplets, rapidly condensing the steam component.
Momentum Transfer & Vacuum Generation
Water jets accelerate through hydro-dynamically designed nozzles, creating a low-pressure region that draws in vapors and NCGs, maintaining a strong vacuum.
Tailpipe Compression
As the two-phase flow of air and water moves down the tailpipe, momentum exchange and compression occur, improving evacuation efficiency.
Heat Recovery & Efficiency
The system effectively reuses residual vapor heat, reducing cooling load and enhancing overall thermal efficiency without any separate vacuum pump.
Key Advantages
