A shell and tube heat exchanger is one of the most efficient designs for transferring heat between two fluids. Known for its large surface area, compact design, and exceptional performance, this system is widely used across industries for heating, cooling, condensation, and evaporation processes.
Goel Impex is a leading glass shell and tube heat exchanger manufacturer in India, providing high-quality equipment made with precision-engineered glass components to ensure durability, corrosion resistance, and superior heat transfer efficiency. Our glass shell and tube heat exchangers are designed to meet diverse industrial requirements with outstanding reliability.
1. Excellent corrosion resistance: Made using high-quality borosilicate glass, it offers universal resistance against corrosive chemicals, making it an excellent alternative to costly materials such as graphite, copper, titanium, hastelloy, and tantalum.
2. Efficient heat transfer: Smooth glass surfaces minimize fouling and ensure consistent thermal performance.
3. Versatile installation: Suitable for both vertical and horizontal mounting depending on process requirements.
4. Easy maintenance: Tubes can be easily replaced or cleaned, reducing downtime and maintenance costs.
5. Wide range of heat transfer areas (HTAs): Available in multiple sizes and capacities for different industrial needs.
6. Lightweight and easy to install: The compact design allows easy handling and installation.
7. Economical and durable: Offers long service life with minimal maintenance.
8. Space-saving design: Ideal for setups requiring large heat transfer areas within limited space.
1. The heat transfer coefficient of a shell and tube type heat exchanger is nearly three times higher than that of a coil-type design.
2. The pressure drop in the shell and tube heat exchanger is significantly lower compared to 2–3 kg/cm² found in coil-type exchangers.
3. For processes requiring large heat transfer surfaces, the shell and tube heat exchanger remains the most efficient and cost-effective choice.
Each glass tube is individually sealed into a PTFE tube sheet using specialized PTFE sockets and packings. This unique ferrule-type sealing system ensures easy tube replacement and cleaning while maintaining leak-proof performance. Baffles on the shell side enhance turbulence, which improves heat transfer efficiency.
The exchangers are constructed using SCHOTT DURAN glass, known for its strength and chemical resistance. The seamless glass tubes offer excellent pressure ratings, ensuring reliability in various industrial applications.
You can refer to the shell and tube heat exchanger diagram for a better understanding of its design and construction.
– Made from SCHOTT DURAN.
– Joint less tubes offer better pressure rating
