SED - Spray Engineering Devices Ltd Limited
Spray Condenser

Multijet Condenser

SED’s multijet condenser is a specialized direct-contact heat exchanger designed for vapor condensation and quick vacuum creation in equipment such as pans and evaporators. It’s a unique combination of SED’s patented spray and jet nozzles ensures rapid condensation and NCG (Non-Condensable Gases) removal with minimal cooling water usage.

How It Works

Working Principle

Step Icon

Vapor Inpu

Vapor generated from the pan, evaporator, or concentrator enters the condenser from the top and comes into direct contact with a controlled spray of cooling water.
Step Icon

Cooling Water Spray

Cooling water is injected through spray nozzles to create a fine mist for maximum vapor contact and through jet nozzles to remove non-condensable gases (NCGs) and generate the desired vacuum.
Step Icon

Direct-Contact Condensation

The hot vapor contacts the cooler water droplets, transferring its latent heat and condensed.
Step Icon

Hot Water Collection

Hot water flows downward through a customized tailpipe, is collected in a channel or header, and then sent to the cooling tower or spray pond for cooling and recycling.
Step Icon

Vacuum Maintenance

Automated control of the jet box valve precisely regulates and maintains the desired vacuum.

Why it’s needed?

01

Minimized Pressure losses due to co-current operation.


02

Compact Size with ease of operation & maintenance.


03

Water jets emerging from the jet nozzles diminish the requirement of a vacuum pump.


04

Consistent vacuum reduces boiling time resulting enhanced steam economy


05

Low water & power consumption


06

Long life with use of corrosion resistant materials.


07

Outlet water can be fed through gravity to the cooling system.
