Compressor Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12825
Jlab Export is a leading Compressor Manufacturer,and suppliers in India
A 1/4 hp motor gives this R-134a compressor more capacity than the 1/6 hp and 1/5 hp models, for domestic refrigerators and freezers with a bigger cooling load. It starts through a PTC relay. Cooling type S means it is statically cooled by still air around the shell.

Test Rig Experiments for Students and Teachers
On the Refrigeration Test Rig, students study the vapour compression cycle and work out the coefficient of performance. They log suction and discharge pressures, temperatures and power input, then plot the cycle on a pressure-enthalpy chart. Teachers can use the results to explain how compressor size sets the refrigerant flow and the cooling a system delivers.
To show what sits inside a sealed shell, teachers can pass round the Reciprocating Hermetic Compressor and Rotary Vane Hermetic Compressor cut-away models. Students compare the two mechanisms and see how each one draws in and compresses the gas.
Frequently Asked Questions
How do I choose between the 1/6, 1/5 and 1/4 hp models?
Go by the horse power and refrigerant printed on the old compressor or the appliance label. A 1/4 hp unit suits a larger cooling load than the smaller models, but it must match the capillary tube and condenser of the system.
Why must the system be evacuated before charging?
Air and moisture left in the circuit raise the head pressure, react with the POE oil and can freeze at the capillary tube. A deep vacuum with a two-stage pump removes them before R-134a goes in.
Why does a fridge stop cooling, then work again later?
An intermittent start fault often lies in the relay, the overload or a loose terminal, which may work when cool and fail when hot. Listen for the compressor clicking on and off, check those parts and the supply voltage, and only then suspect the compressor itself.
What should I check if a new compressor runs but does not cool?
Check the charge, look for a blocked capillary tube or filter drier, and confirm the compressor is pumping by watching suction and discharge pressures. A compressor that runs with nearly equal pressures on both sides is not compressing.
