Chest Freezer Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12802
Jlab Export is a leading Chest Freezer Manufacturer,and suppliers in India
A chest freezer opens from the top, so the heavier cold air tends to stay in the cabinet when the lid is lifted. This 500 litre model has an adjustable control that runs it as a freezer from -18 to 0 °C or as a chiller from 0 to 10 °C. It has 75 mm insulated walls, a digital display, R-134a refrigerant and castor wheels.

Chest Freezer Lab Exercises
A pull-down test is the first job. Trainees connect the Manifold Gauges For Refrigeration Systems, which carry an R-134a scale. They log cabinet temperature with suction and discharge pressures from switch-on until the set point is reached. Plotting the readings shows how the pressures fall as the cabinet cools. The class then sets chiller mode and repeats the run to compare the two curves.
For a recharge exercise, the R-134a is taken out with the Refrigerant Recovery Machine and the circuit is evacuated with the Small Vacuum Pumps. A cylinder of R-134a Refrigerant on the Wireless Refrigerant Charging Scale is used to weigh the nameplate charge back in. Students then work out superheat from the suction reading and a pipe thermometer.
Frequently Asked Questions
Can this chest freezer also work as a chiller?
Yes. The adjustable temperature control sets it as a freezer between -18 and 0 °C or as a chiller between 0 and 10 °C. One cabinet can therefore hold frozen stock or chilled food and drinks.
What refrigerant and power supply does it use?
It runs on R-134a and needs a 220–240 V, 50 Hz supply. For service readings use manifold gauges with an R-134a temperature scale.
How is the freezer defrosted?
Frost slowly builds on the inner walls of a chest freezer. Switch it off, empty it and leave the lid open. The meltwater then runs out through the defrost water drain into a tray or bucket.
Why does the insulation thickness matter?
The walls carry 75 mm of insulation. Thicker insulation lets less heat leak into the cabinet, so the compressor runs for a smaller share of each hour to hold the set temperature.
Can it be moved around a lab or store?
Yes. It stands on heavy duty castor wheels, and the lid has a handle and a lock with key. After moving it, let the freezer stand for a while before switching on so the compressor oil can settle.
