Modular Refrigeration System Trainer Manufacturer,Supplier and Exporter in India

Product Code : EL-TWL-13133
Jlab Export is a leading Modular Refrigeration System Trainer Manufacturer,and suppliers in India

Real industrial refrigeration components, each mounted on its own panel, slot into the three-level mobile frame of this modular trainer. Three compressor types, three expansion devices and a full set of pressure, defrost and temperature controls let students assemble several circuits on one frame and practise fault finding. It runs on 220–240 V, 50 Hz.

Experiments on the Modular Trainer

A common first exercise compares the three compressors. Students build the same circuit with the hermetic, then the semi-hermetic, then the open compressor, and record pressures, voltage and current from the panel meters. Before that lesson, a cut model such as the Semi-Hermetic Two Piston Reciprocating Compressor shows the inside of a semi-hermetic design.

Next, students change the expansion device. They run on the capillary tube, then on each thermostatic expansion valve. From the flow meter, gauges and coil temperatures they plot each cycle on a p-h chart and work out the coefficient of performance. Each new circuit is evacuated with one of the Fast Vacuum Pumps and charged through Manifold Gauges For Refrigeration Systems. For fault finding, the teacher partly closes the manual fault valve or alters the defrost timer wiring while students trace the cause from the readings.

Frequently Asked Questions

Which compressors are included?
Three: a 3/4 HP hermetic, a 3/4 HP semi-hermetic and a 1 HP open type driven by an electric motor. Students compare a welded shell design, a bolted serviceable design and one with an external motor on the same circuit.

How is it different from the basic modular trainer?
The Basic Modular Refrigeration System Trainer is a two-level frame built round a single hermetic compressor and capillary tube metering. This one has three levels and three compressor types. It also carries two thermostatic expansion valves, an oil separator, a tube-in-tube heat exchanger, a defrost timer and a flow meter.

What power supply does it need?
A 220–240 V, 50 Hz supply. The control panel carries a voltmeter, an ammeter and an on/off switch, so students can read the supply voltage and the current drawn while each circuit runs.

How are faults simulated?
A manual valve in the circuit lets the teacher restrict refrigerant flow, much as a blocked drier or a kinked line would. Students find the fault from the gauges, flow meter and sight glass, then explain what they saw.

What accessories come with it?
A set of refrigerant hoses, a set of 4 mm² connecting leads and an experimental manual. An instructional manual and a student job sheet for the exercises are also part of the supply.
