How to control the temperature of the outlet water of the low-temperature chiller?
Nov 05 , 2021
The structure of low-temperature chillers is similar to that of piston chillers. Low-temperature chillers generally refer to chillers whose outlet temperature is less than or equal to 5°C. They are mainly used for process cooling in food processing, chemical, pharmaceutical and other industries. Low-temperature chillers are usually used for low-temperature requirements on certain special productio...

Ways and solutions of noise produced by chillers
Nov 19 , 2021
It is inevitable that the chiller will produce sound when it is working. For example, when the fan rotates, the fan blades rub against the air, it will produce sound. Normal sound is allowed. However, even the sophisticated refrigeration equipment will appear after a long period of use. Fault. Then, the editor of Oumal Chiller will take you to understand the causes and solutions of the noise produ...

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...

What are the differences between air-cooled chillers and water-cooled chillers
Jan 06 , 2022
We all know that according to different heat dissipation methods, chillers can be divided into air-cooled chillers and water-cooled chillers. What is the difference between air-cooled chillers and water-cooled chillers? 1. The air-cooled chiller uses copper tubes and aluminum fins to dissipate heat from the condenser. A fan is required to blow the outdoor air through the heat exchange fins and tak...
