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...

Basic maintenance of high and low temperature refrigeration circulating pumps
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...

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 ...
