Parallel and Counter Flow Heat Exchanger (Product Code: SLE/MCE/74) is a concentric-tube heat exchanger trainer used to compare parallel-flow and counter-flow operation and to determine the heat transfer coefficient in heat transfer laboratories. As engineering educational equipment for colleges and research laboratories, it combines two insulated stainless steel tube sections with a 3000 W heated hot-water tank, hot- and cold-water flow meters and data acquisition software. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

In parallel flow the hot and cold streams enter at the same end and their temperatures converge along the tube; in counter flow they enter at opposite ends, so the cold outlet can approach the hot inlet temperature more closely. Switching between the two on the same exchanger lets students measure inlet and outlet temperatures of both streams, calculate the log-mean temperature difference, heat duty and heat transfer coefficient, and see for themselves why counter flow is usually more effective.
Changing the hot and cold water flow rates, and the hot water temperature through the temperature control unit, shows the effects of flow rate and temperature difference on performance. Let the hot water tank reach its set temperature before the first reading, keep both flows steady during each run, and use the data acquisition software to build a complete record for effectiveness calculations.
Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM behind the Parallel and Counter Flow Heat Exchanger. The trainer is built at the company’s own licensed factory in Saha, Ambala, Haryana, India, and dispatched factory-direct to engineering colleges, research laboratories, laboratory dealers and importers.
As an engineering lab equipment manufacturer, the company answers spares and repeat-order queries itself — just ask us. Company background is on the profile page.
Heat exchanger laboratories usually compare several designs; these complete the set:
All heat exchanger trainers are listed in the Thermodynamics & Heat Transfer Lab Equipment category.
Can the Parallel and Counter Flow Heat Exchanger run in both flow modes?
Yes. The Parallel and Counter Flow Heat Exchanger demonstrates heat transfer under both parallel flow and counter flow, so students can compare temperature profiles, heat duty and heat transfer coefficient for the two arrangements on one unit.
What is the Parallel and Counter Flow Heat Exchanger built from?
The Parallel and Counter Flow Heat Exchanger is built from two sections of insulated concentric stainless steel tubes, supplied with hot water from a tank heated by a 3000 W heater and circulated by a pump.
What instruments does the Parallel and Counter Flow Heat Exchanger have?
The Parallel and Counter Flow Heat Exchanger has six temperature measuring points, hot- and cold-water flow meters, one temperature control unit and software for education, data acquisition and system operation.
How large is the Parallel and Counter Flow Heat Exchanger?
The Parallel and Counter Flow Heat Exchanger measures 1200 × 600 × 800 mm and weighs 40 kg, so it can be placed on a laboratory bench or table close to a water supply and drain.
Who manufactures the Parallel and Counter Flow Heat Exchanger?
Jain Scientific Equipments Pvt Ltd (ScienceLab) is the OEM of the Parallel and Counter Flow Heat Exchanger and makes it at its own factory in Ambala, Haryana, India; quotations come directly from the manufacturer.
Is a calibration certificate available for the sensors?
Calibration-certificate availability for the temperature sensors and flow meters of the Parallel and Counter Flow Heat Exchanger should be discussed with us at the enquiry stage. Please list your documentation needs on the contact page.
What should a quotation request for this heat exchanger include?
For a Parallel and Counter Flow Heat Exchanger quotation, tell us the number of units, your power supply (230 V 50 Hz, 230 V 60 Hz or 120 V 60 Hz) and the delivery location in India or abroad.
