Thermostats 2 Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12830
Jlab Export is a leading Thermostats 2 Manufacturer,and suppliers in India
Built for bottle coolers, this thermostat holds beverage storage between 2 and 10 °C. At its maximum setting it switches the compressor on at 10.5 °C and cuts off at 5.0 °C. At the minimum setting the figures are 3.0 °C and -4.5 °C, so every dial position falls between these two pairs.

Experiments with a Bottle Cooler Thermostat
Using a bath of ice, salt and water, students chill the sensing tube while a Calibrateable Digital Thermometer reads the bath. A Multimeter Digital on its resistance range shows the moment the contacts open. Repeating the test at both ends of the dial lets them compare their cut-off readings with 5.0 °C and -4.5 °C.
Teachers can then wire the thermostat into the compressor circuit of a Refrigeration Test Rig and log the evaporator temperature through several cycles. Plotted against time, the readings form a saw-tooth curve whose peaks and dips mark the cut-in and cut-out points.
Frequently Asked Questions
What do the maximum and minimum setting figures mean?
They are the switching points at the two ends of the dial. Turned to maximum, the thermostat starts the compressor at 10.5 °C and stops it at 5.0 °C. Turned to minimum, it starts it at 3.0 °C and stops it at -4.5 °C.
Why does the cut-off go below 0 °C at the coldest setting?
In a bottle cooler the sensing tube is usually clamped to the evaporator, which runs colder than the bottles. The drinks sit away from the coil and stay warmer. Because the cut-in stays above 0 °C, the coil also clears its frost before each restart.
Is it suitable for a household refrigerator?
It is set up for bottle coolers, where drinks are kept at 2 to 10 °C. A single-door direct-cool fridge uses Thermostats 1, which is made for a refrigeration compartment.
What should I check if the cooler stays warm?
First check that the dial is not at maximum and that the sensing tube is still in its clamp. Then test the contacts with the tube chilled. If the compressor never starts although the contacts close, look at the relay, the overload and the supply instead.
