About Shell and Tube Heat Exchanger Apparatus
Shell and Tube Heat Exchanger Apparatus
We at Engineering Laboratory Equipment has a vision to develop & design Shell Tube Heat Exchanger so as to meet the customers requirement through continual endeavor & innovation. Our company is well managed with a team of highly qualified personnel with an experience of more than two decades and active involvements in foreign business to develop.
Shell and Tube Heat Exchanger are popular in industries because they occupy less space and offer reasonable temperature drop. The apparatus consists of fabricated SS shell, inside which copper tubes with baffles on outer side are fitted. This is two-pass heat Exchanger so that hot water passes to one end of shell through the tubes and returns to another end through remaining tubes. The cold water is admitted at the one end of shell, which passes over the hot-water tubes. Valves are provided to control the flow rates of hot and cold water. Flow rates of hot and cold water are measured using Rota meters. A magnetic drive pump is used to circulate the hot water from a re-cycled type water tank, which is fitted with heaters and Digital Temperature Controller.

Dual Flow Demonstration CapabilityThis heat exchanger allows clear comparison of parallel and counter flow configurations, aiding students in understanding thermal efficiency differences. The transparent shell section provides excellent visual access to internal fluid movement, making demonstrations engaging and illustrative. This feature enhances the observation of physical heat exchange processes in real-time.
Robust and Reliable ConstructionThe apparatus is built using powder-coated mild steel for structure and stainless steel for all wet parts, including the shell and tubes. This ensures resistance to corrosion, easy maintenance, and long-term performance, even under frequent use in laboratory environmentsideal for academic, research, and teaching applications.
FAQs of Shell and Tube Heat Exchanger Apparatus:
Q: How does the Shell and Tube Heat Exchanger Apparatus simulate parallel and counter flow patterns?
A: The apparatus is engineered with inlet and outlet valves and clearly marked connections, enabling users to arrange water flow in either parallel or counter directions. This flexibility allows direct comparison of temperature profiles and heat transfer rates between the two flow modes during laboratory experiments.
Q: What is the core benefit of using this heat exchanger in a teaching laboratory?
A: The apparatus offers a hands-on platform for studying foundational heat transfer principles, enhancing theoretical lessons. Its transparent section allows students to observe flow dynamics directly, while digital/analog thermometers and PT-100 sensors ensure accurate data collection for detailed analysis.
Q: Where is this Shell and Tube Heat Exchanger typically used?
A: This equipment is widely utilized in educational institutions, such as university laboratories and technical training centers, for demonstrations, practical classes, and research in heat transfer and thermodynamics.
Q: What is the measurement range and accuracy of the temperature sensors?
A: Temperature measurements range from ambient up to 100C, with an accuracy of 1C, provided by high-quality PT-100 thermocouples and digital or analog displays. This ensures reliable results suitable for academic experiments.
Q: How can experimental data be recorded using this apparatus?
A: Data can either be logged manually, using digital or analog thermometer readings, or through an optional data logging system (if equipped), allowing instructors and students to track performance under different flow conditions.
Q: What process is followed for setting up and operating the apparatus?
A: Setup involves filling the water tank, connecting the power supply, and selecting the desired flow arrangement. After configuring valves and switching on the centrifugal pump, temperature readings can be observed and recorded at designated measuring points. Flow rates are monitored via the rotameter, and heat transfer can be studied under varying conditions.
