Ethylene glycol refrigeration unit made a strong attack and created LNEYA brand in 12 years
Performance enhanced positioning When performing the cooling and heating reaction, in many cases, the refrigerant cannot cool the object to be cooled by itself. Therefore, we need a coolant (or refrigerant) to cool the refrigeration system in a relatively small range. The suitable brine is undoubtedly ethylene glycol. Compared with water, the freezing point is high and the salt water is corrosive. Ethylene glycol is currently a suitable refrigerant for everyone. Therefore, in response to this...

How to save energy in the vacuum chamber refrigeration heating thermostat control unit
In the environment of energy-saving and emission-reduction operation, how to operate the LNEYA vacuum chamber cooling and heating thermostat control unit is very important. Let's take a look at a few tips to reduce the consumption and see how to use it. The very important first step in the selection of the vacuum chamber cooling and heating thermostat control unit is that the cooling capacity is too small, which affects the production, and often loses more than the loss; however, the excessiv...

LNEYA bearing freezer refrigeration principle description
LNEYA industrial freezer can be used in the refrigeration process of the bearing industry. Since the use of bearing freezer is relatively large, the performance is very important, so let's talk about the principle today. The refrigerant in the bearing freezer circulates in the refrigeration system under the action of the mechanical energy generated by the compressor, and is repeatedly operated in a gaseous state or a liquid state. During this process, the refrigerant continuously absorbs the ...

Closed circulation cooling system debugging attention note
Closed circulation cooling system needs to pay attention to some common problems during commissioning. Do a good job in debugging work. LNEYA manufacturers remind users that only when they are ready to work can they be better debugged. The preparation work before the commissioning of the closed circulation cooling system is an important part of the debugging process, which may affect the progress of the whole debugging process. Generally, it is necessary to pay attention to the leakage detect...

The principle of LNEYA chiller
Industrial chillers are commonly used to cool products and machinery for a variety of different applications, including injection molding, tools and die cutting, food and beverage, chemicals, lasers, machine tools, semiconductors and more. In most process cooling applications, the pumping system circulates cold water or water/glycol solution from the chiller to the process. This cooled fluid removes heat from the process and the warm fluid returns to the cooler. Process water is a means of tr...

What are the common debugging problems in low temperature refrigeration baths?
When the low-temperature cooling bath is in debugging, if the local cooling effect is not good, the system may be blocked by foreign matter or the system design is unreasonable and cannot be adjusted normally. At this time, LNEYA removes foreign matter and thoroughly cleans it to adjust the slope of the pipeline. When debugging, it is found that the vibration and noise of the pump are large when it is running. It may be that the axial and radial deviation of the coupling is large. It may be t...

The consequences of the screw refrigerator not returning oil and the treatment method
In the cooling operation of the screw refrigerator, if the refrigerant is in contact with the lubricating oil, the lubricating oil in the compressor will enter the condenser with the operation of the refrigeration system and the gaseous or misty refrigerant, and the oil separator is encountered. If the effect is not good or the refrigeration system is not well designed, it will cause problems such as poor oil return. If the screw chiller has a problem of oil return, it will cause the lubricat...
