Industrial Refrigeration Training Unit Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-13137
Jlab Export is a leading Industrial Refrigeration Training Unit Manufacturer,and suppliers in India
Water cooled condensing and forced-air evaporators bring this freestanding trainer closer to an industrial cold store plant than to a domestic system. It carries two water cooled condensers, one tube-in-tube and one shell-in-tube, served by a water tower and pump. Two evaporators with different defrost methods and a crankcase pressure regulator complete the circuit.

Plant Room Practicals
Condenser tests come first. Students run the plant on the tube-in-tube condenser, then on the shell-in-tube condenser, and record the water inlet and outlet temperatures and the condensing pressure each time. From a timed water flow and the temperature rise they work out the heat rejected and compare the two designs. The tower side is studied further on the Cooling Tower Test Rig, where students find the tower characteristic and the make-up water rate.
The crankcase pressure regulator is shown by starting the plant after a defrost, when evaporator pressure is high. Students compare the evaporator pressure with the suction pressure the compressor sees and measure the starting current with a Digital Clamp Meter. A cut-open regulator in the Six Piece Sectioned Regulator Set For Demonstration shows the spring and valve doing this work. Defrost sessions then compare the two methods on the two evaporators.
Frequently Asked Questions
Why does it have two kinds of water cooled condenser?
They are the two standard designs. In the tube-in-tube type, water and refrigerant flow through a tube inside a tube. In the shell-in-tube type, refrigerant condenses in a shell around the water tubes. Students compare pressure and heat transfer in each.
What does the crankcase pressure regulator do?
It limits the suction pressure reaching the compressor. After a defrost or a warm start the evaporator pressure is high, and without the regulator the motor would be overloaded. With it, the compressor starts easily and the system pulls down gradually.
What are the water tower and pump for?
The pump sends water through the condensers, where it picks up heat from the refrigerant. In the tower, part of the water evaporates into the air stream and cools the rest, which then returns to the condensers.
What comes with the unit?
A lab manual, operation instructions and a manifold service kit. The unit is self-contained and freestanding, with storage space for the kit and the tools used in the exercises.
How does it differ from the commercial training unit?
The Dual-Application Commercial Refrigeration Training Unit is built around a fan-cooled condenser and two evaporating temperatures. This industrial unit adds water cooled condensers, a water tower and a crankcase pressure regulator, and compares two defrost methods.
