Shell & Tube Heat Exchangers operate by transferring heat between two fluids—one passing through the tubes and the other flowing around them within the shell. The efficiency is enhanced by: 

• Turbulent Flow: DNA, B, REV, and TI variants utilize spiral or corrugated tubes to create turbulence, improving heat exchange and preventing deposits. 
• Multi-Pass Flow Paths: REV’s 3-pass design extends the residence time of the heating medium, maximizing efficiency. 
• Dismountable Components: ST variants allow for mechanical cleaning and modular expansion. 
• Sanitary Design: P-Line ensures zero cross-contamination for pharmaceutical applications. 
• Corrosion Resistance: DNA, TI, and P-Line variants use high-grade stainless steel or titanium for durability in aggressive environments.
