Heat Exchangers
Shell & Tube Heat Exchangers
At Shree Shakti Engineering Works, we design and manufacture high-efficiency Shell & Tube Heat Exchangers to handle challenging thermal duties across chemical, petrochemical, pharmaceutical, and allied industries. Our exchangers are optimized for both thermal performance and mechanical strength, and built in accordance with TEMA, ASME, and IS standards.
We offer solutions using plain, corrugated, or finned tubes, depending on process needs such as heat transfer rate, pressure drop, and fouling behavior.
Functional Classification
Our heat exchange equipment is designed for various functional roles in process systems :
- Heat Exchanger – General-purpose thermal energy transfer between fluids
- Condenser – Vapor to liquid phase change via cooling
- Reboiler – Liquid vaporization for distillation columns
- Evaporator – Concentration of solutions via solvent evaporation
- Cooler / Chiller – Temperature reduction of process streams
- Heater / Preheater – Raising fluid temperature before reaction or mixing
Construction Types Offered
- Fixed Tube Sheet – For clean, non-corrosive fluids
- U-Tube Bundle – For thermal expansion tolerance
- Floating Head – Easy cleaning and maintenance access
- Double Pipe / Hairpin Type
- Multi-Pass Tube Side Design – 1-1, 1-2, 2-4 passes for efficient performance
