Tubular Heat Exchanger Manufacturer,Supplier and Exporter in India
Product Code : EL-HTTLP-9204
Jlab Export is a leading Tubular Heat Exchanger Manufacturer,and suppliers in India
Tubular Heat Exchanger (code EL-HTTLP-9204) is a small-scale concentric-tube heat exchanger that works with the JLab Heat Exchange Service Unit to teach the basic workings of heat exchangers. Its outer section is clear acrylic, so the flow can be seen, and the inner tube is stainless steel. JLab makes the tubular exchanger in Ambala, India, in a 2-section version and a 4-section version.

What the Six and Ten Temperature Points Show
The 6-point version reads the hot and cold fluids at inlet, mid-position and outlet. The 10-point version reads each fluid at its inlet, at three interim positions and at its outlet, so the temperature profile of both streams can be drawn along the exchanger instead of only at its ends.
With the flow rate of each stream, the inlet and outlet temperatures give the heat given up by the hot fluid and taken up by the cold fluid (mass flow × specific heat × temperature change); the difference between them is heat exchanged with the surroundings. The end-to-end temperature differences between the streams give LMTD = (ΔT1 − ΔT2)/ln(ΔT1/ΔT2), and the overall coefficient follows as U = Q/(A × LMTD), with A from the table.
Changing the Number of Sections
Because the 4-section version also runs with 1, 2 or 3 sections, the area can be stepped up to its 0.08 m² maximum and the effect on outlet temperatures, U and effectiveness compared. Effectiveness is the heat transferred divided by the most the inlet temperatures allow, C_min × (hot inlet − cold inlet), where C_min is the smaller of the two streams’ mass flow × specific heat. The tubes dismantle easily for cleaning, and an instruction manual is included.
Other Concentric-Tube and Cross-Flow Exchangers
- Parallel and Counter Flow Heat Exchanger — concentric tube unit whose cold water can run parallel or counter to the hot.
- Cross Flow Heat Exchanger — small-scale water-and-air cross-flow unit for the Heat Exchanger Service Unit.
- Concentric Tube Heat Exchanger — copper inner tube inside a GI outer pipe, for parallel or counter flow.
More heat transfer trainers are collected under Heat Transfer Lab Equipment; this exchanger is filed in Heat Transfer Through Lagged Pipe.
