Basic Modular Refrigeration System Trainer Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-13130
Jlab Export is a leading Basic Modular Refrigeration System Trainer Manufacturer,and suppliers in India
This basic modular trainer splits a small refrigeration and air conditioning circuit into separate modules that students connect themselves. It has a hermetic compressor, a forced-air condenser, flow control and pressure control modules, a finned evaporator with fan and capillary tube, and a power supply module. All of them sit on a two-level mobile aluminium frame with storage space.

Practicals on the Modular Trainer
The first practical is to build the circuit. Students join the compressor, condenser, flow control and evaporator modules with the flexible pipes, then wire the power supply module, pressure switch and fans with the test leads. The circuit is evacuated with one of the Small Vacuum Pumps before the teacher charges it. After charging, students go over every joint with an Infrared Refrigerant Leak Detector.
With the system running, students read the high and low pressure gauges, measure the temperatures at the evaporator and condenser, and work out superheat and subcooling. Slowing the condenser fan with the speed controller makes the head pressure rise. Closing the shut-off valve on the flow control module pumps the system down until the low pressure side of the double pressure switch stops the compressor. A Digital Clamp Meter on the compressor supply shows how the current changes in each test.
Frequently Asked Questions
What does a student build on this trainer?
A complete vapour compression circuit. Each part sits on its own module with shut-off valves and terminals. Students pipe and wire the modules together, then run and test the system they have made.
What does the double pressure switch do?
It combines a low pressure switch and a high pressure switch in one body. It stops the compressor if suction pressure falls too low or discharge pressure rises too high, and students can watch both cut-outs act on the module gauges.
How is it different from the larger modular trainer?
This basic version has one hermetic compressor and a capillary tube on a two-level frame. The Modular Refrigeration System Trainer adds semi-hermetic and open compressors, thermostatic expansion valves, a refrigerant flow meter and a defrost timer on a three-level frame.
What comes with the trainer?
A set of flexible pipes, test leads and capillary tubes for building the circuits, plus an instruction manual and student job sheets for the exercises.
Why are the connections made with safety plugs?
Students change the wiring for each exercise. The 4 mm² heavy duty terminals take test leads with safety plugs, so a circuit can be rewired quickly without stripping wires or loosening screw terminals.
