You Should Know Something About Ultra Low Temperature Freezer
Ultra low temperature freezer is an indispensable cryogenic storage equipment in the field of life sciences and biopharmaceuticals. It can be used to store cells, tissues, test samples, vaccines, active enzymes, strains, plasmids, viruses, bacteria, blood red blood cells, white blood cells, germplasm banks and other high value-added samples for ultra-low temperature storage. It can also cooperate with carbon dioxide incubator and stability test box to serve in the fields of drug screening opt...
View detailsHow to Choose Water Chiller Units in Small Factories
Professional water chiller factory said that the quality of equipment can be seen from the three main components of small water chiller units. The most important one is the compressor, which is the heart of the unit and the most critical component. A good compressor should not only run stably, but also ensure good energy efficiency.Evaporator and condenser are also one of the main components of water chiller. Evaporator and condenser play the role of heat absorption and exothermic respectivel...

2. Air-cooled module internal filter, in order to better filter impurities in the water system, the protective plate heat exchanger is generally more than 40 meshes, that is to say, its filter is more dense and finer than other brands. The advantage of this method is that it can filter impurities better, and the disadvantage is that the number of cleaning increases. But compared with the air-cooled module machine, the closed circulating water system can better ensure the cleaning of the water...

What are the effects of power failure on liquid nitrogen cryogenic cold box?
Different industries have different temperature requirements for cryogenic cryostats. Of course, there are many types of cryogenic cryostats. The refrigeration methods used in different industries are different. LNEYA uses compressor refrigeration to achieve refrigeration. The effect is similar to or better than liquid nitrogen cryogenic cryostat. However, there are still customers who use liquid nitrogen cryogenic cryostats, and customers who encounter power failures when they encounter them...
View detailsWhat are the effects of oil level and oil difference in low temperature chillers?
LNEYA tells you that in addition to the refrigeration system, the lubricating oil system is also an important part, with its own oil storage and special oil cooler. Oil level It refers to the level of the lubricant in the oil storage container. The oil storage container of the low temperature chiller is provided with an oil level display device. Generally, the oil level in the oil storage container should be 5 mm below the central horizontal line of the mirror. The purpose of specifying the h...

Battery test chiller operation evaporating temperature description
In the current new energy vehicle battery test equipment, the use of more batteries to test the chiller evaporation temperature has a certain impact on the equipment, then what is the specific impact? When the battery test chiller heat load increases, other conditions remain unchanged, the evaporation temperature will rise, the low pressure will also increase, and the superheat of the suction will increase. In this case, the battery test chiller can only open a large expansion valve to increa...

How to solve the problem that the cooling pump centrifugal pump power consumption becomes larger?
There are many opportunities for the centrifugal pump in the chiller, but the failure of the centrifugal pump will affect the use of the chiller. Therefore, do not worry if the centrifugal pump power becomes larger, find out the cause in time, and solve it in time. The cooling machine centrifugal pump works by rotating the impeller to make the water centrifugally. Before the pump starts, the pump casing and the suction pipe must be filled with water, and then the motor is started, so that the...
