Direct Steam Injection
Liquid Heating Systems
Pick Direct Steam Injection Heating Systems can be used to heat any water miscible liquid or aqueous slurry instantly.
The Pick system injects steam into the liquid through hundreds of small orifices in the injection tube. The unique spring-loaded piston rises or falls in response to changes in steam flow. This prevents pressure equalization between steam and water pressure, eliminating steam hammer.
The heart of the Pick Heater is the steam injection tube and piston.
This serves three critical functions:
• Breaks steam into small streams.
• Piston modulates in response to changes in steam demand to maintain a differential between steam and water pressure.
• Piston closes during shutdown to prevent sudden collapse of steam inside the tube.
With its simple design, minimal moving parts and exceptional energy efficiency, Pick Direct Steam Injection (DSI) systems regularly outperform Heat Exchangers.
