How to choose a heating and cooling circulating water bath?
Heating and recirculating water bath In the process of selection, heating power, cooling power, pressure and flow are also factors that users need to consider. Good system design and accessory brand selection are related to the whole heating and cooling cycle water bath selection. As far as the heat transfer medium of the heating and cooling cycle water bath is concerned, water is used as a heat transfer medium, which is economical and environmentally friendly. Even if a leak occurs, it can b...

Manutenção básica de bombas de circulação de refrigeração de alta e baixa temperatura
Properly perform the sequence of opening and closing of the high and low temperature refrigeration cycle pump group to ensure normal operation after the host is started. Note that the condenser heats up well, otherwise the high temperature protection device of the high and low temperature refrigeration cycle pump group will stop and even cause malfunction due to the condensing temperature and the corresponding condensing pressure being too high. The cold water in the evaporator should be circ...

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...

Como poupar energia na unidade de controlo do termóstato de aquecimento e refrigeração da câmara de vácuo
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...

Descrição do princípio de refrigeração do congelador de rolamentos LNEYA
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...
