The cryogenic coolant circulation pump is especially suitable for chemical, biological and physical laboratories that need to maintain low temperature and normal temperature. It is a well-known laboratory in medical, chemical, food, metallurgy, tertiary industry, scientific research, Genetic engineering, polymer engineering laboratory essential equipment. Far East Centrifugal Pump to provide coolant circulation pump Notes: 1, Before using the cryogenic coolant circulation pump in the tank should be added to the liquid medium (pure water, alcohol, antifreeze can be), the medium level should not have been cooling tank Coil and lower than the table 20mm is appropriate. 2, the power: 220V50Hz, the power supply should be greater than the total power of the instrument, the power supply must have a good "grounding" device; 3, to avoid acid-base substances into the tank corrosion coil and the liner. 4, the instrument should be placed in a dry and ventilated place, no obstacles within 300mm around the instrument; 5, always observe the level of tank surface, when the liquid level is too low, should be timely added liquid medium 6, when the low temperature coolant circulation pump work When the temperature is low, care should be taken not to open the upper cover, hands do not enter the slot to prevent frostbite; 7, the use is completed, all the switches placed in the closed state, cut off the power; 8, liquid outside the loop, Firmly connected to prevent the fall off, so as to avoid liquid leakage. 9, the instrument should be regular cleaning, long time do not have to empty the tank of the media, and wipe clean, keep the work surface and the operation panel clean.
