How to choose the type of refrigerant for the chiller?
Sep 23 , 2021
The normal and safe operation of the chiller is inseparable from the refrigerant. It is the working medium that circulates in the chiller refrigeration system to achieve refrigeration. The commonly used refrigerant types for chillers are: R22, R407C, R404A, R410A, R134A, R507... Because R22 refrigerant is not environmentally friendly, most countries have now banned the use of R22. Therefore, for O...

How to size a chiller for spot welding machine?
Dec 17 , 2021
Spot welding machine is a kind of mechanical equipment. It adopts the principle of double-sided double-point overcurrent welding. When working, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and the welding current changes from one When the electrode flows through the other electrode, the two conta...

What causes the high-pressure failure of your water chiller machine? How to solve it?
Dec 22 , 2021
The high-pressure failure of the chiller means that the compressor discharge pressure is too high, which causes the high-pressure protection relay to operate. The compressor discharge pressure reflects the condensing pressure, the normal value should be 1.4~1.8MPa, and the protection value setting is recommended not to exceed 2.0MPa. Because the long-term pressure is too high, it will cause the co...
