- Customizable Sizes: Available in multiple sizes to cater to different heat transfer area (HTA) requirements.
Advantages Over Coil-Type Heat Exchangers:
Why Choose Shell and Tube Heat Exchangers Over Coil Type?
- Superior Heat Transfer: Our Shell and Tube heat exchangers offer up to three times higher heat transfer efficiency than conventional coil-type exchangers.
- Minimal Pressure Drop: With minimal pressure loss compared to coil-type heat exchangers, our units maintain consistent performance.
- Ideal for Large-Scale Operations: Best suited for applications that demand large heat transfer areas (HTA) in a compact design.
Heat Exchanger Design: Robust Construction for Optimal Performance
- Glass Tubes and PTFE Sealing: Our exchangers use individually sealed glass tubes fitted into a PTFE tube sheet, with a ferrule-type sealing mechanism for easy tube replacement and cleaning.
- Strategic Baffle Placement: Baffles on the shell side increase turbulence, enhancing the heat transfer rate. For a detailed view of the construction, refer to the provided diagram.
- Durable Materials: Constructed using SCHOTT DURAN borosilicate glass for superior chemical resistance, coupled with PTFE for non-reactivity and longevity.
