Refrigeration cycle tank ( pump ), also known as cryogenic constant temperature bath, is a high-precision thermostat with cooling, both small chiller functions. Widely used in petroleum, chemical, metallurgy, medicine, biochemistry, physical properties, testing and chemical analysis and other research departments, universities, factory laboratories and measurement of quality inspection departments. According to the different size of the slot opening, the thermostat experiment can be carried out in the bath, but also through the hose and other equipment connected to the constant temperature source supporting the use of. Internal circulation: through the pump on the tank liquid medium circulation throughput, increase the uniformity of temperature within the tank to reduce temperature fluctuations. External circulation: Through the circulation capacity of the pump, the outlet pipe is used to connect the insulation hose with the external equipment to form a closed circuit and return to the water inlet of the equipment. The external temperature medium is introduced into the tank to establish an external constant temperature field.
Circulating water temperature applications:
Biochemistry: Rotary Evaporator, Abbe Refractometer, Polarimeter, Atomic Absorption, ICP-MS, ICP, NMR, CCD, Bio Fermentor, Chemical Reactor (Synthesizer) and more. Materials: Electron microscopy, X-ray diffraction, X-ray fluorescence, vacuum sputtering plating, vacuum coating machine, ICP etching, various semiconductor equipment, fatigue testing machine, chemical deposition system, atomic deposition system.

Low temperature antifreeze liquid ratio A. Ethylene glycol aqueous solution: ethylene glycol / water 55/45 (-30 ℃), 70/30 (-40 ℃)
B. Glycerol solution: Glycerol / water 70/30 (-30 ℃) During use, it is necessary to constantly check the density of the antifreeze solution to meet the following requirements:
(1) Ethylene glycol aqueous solution: P20 = 1079? / M3 (-30C) (-40C)
(2) Glycerol solution: P20 = 1182.6? / M3 (-30 ℃) When the antifreeze solution is replaced with water, its minimum temperature must be above 0 ℃.
Cooling water selection related:
Typically, the cooling capacity of less than 1000W Small circulating water cooling thermostat extensive use of low-power laser, parallel evaporation, parallel quantitative enrichment, parallel reactors, distillation and other laboratory condensing devices. Refrigeration capacity below 6000W Medium-sized circulating water cooling thermostat is widely used in AAS, ICP, ICP-MS, electron microscope and other analytical instruments industry, rotary evaporator, Soxhlet extraction, solid-liquid extraction instrument, Kjeldahl apparatus and other laboratory equipment , Laser marking machines, laser cutting machines and other laser equipment and machine tool industry. Refrigeration capacity of more than 10KW Large circulating water cooling thermostat is widely used in X-ray diffraction, magnetic mass spectrometer, fatigue testing machine, vacuum coating machine, plastic forming equipment, laser cutting machine, X-fluorescence spectrometer, infrared spectrometer, Instrument, nuclear magnetic resonance and other equipment with high cooling temperature requirements.

common problem:
1. Water cycle used more than a year are normal, but now the cooling rate seems slower and slower, the more obvious when the temperature is higher?
A: The water cycle is simple to use, but regular maintenance can not be ignored. There are many problems that appear to be malfunctioning, which is caused by the fact that there is no regular maintenance. The electrical power of the water cycle and the heat that the refrigerant takes away from the load need to be dissipated from the radiator at the front vent hood and if the front vent hood is full of dust and willows, it will prevent the heat from dissipating Greatly reduced. In general, under normal conditions of use cooling capacity decline is due to ventilation cooling effect is too poor or caused by the ambient temperature is too high.
2. The water cycle used to be normal before, but now we found the noise much larger than before, what is the reason?
A: The aforementioned routine maintenance work on the water cycle is also related to this issue. We all know that there are very few impurities in the water, that is, distilled water can not be completely guaranteed after adding water tank. For the water cycle, the general temperature is set at 20 ℃, in particular, adapt to the growth and reproduction of microorganisms. After a long time these microorganisms will block the water filter caused by poor return, the pump will have a lot of noise. Sometimes these microorganisms are attached to the surface of the heat exchanger, resulting in deterioration of the heat transfer effect of the heat exchanger, resulting in a decrease in cooling capacity. Therefore, we must strictly follow the instructions in the routine maintenance work, regular cleaning of the tank, long-term deactivation, keep the tank dry. Water circulation seems to have leaks, sometimes a few drops on the ground a while, is not there a place on the water leak? In general during normal use, there is no leakage of waterway. Relatively high temperature in the air when the relative humidity in the air is too large, water pumps in the water cycle, water pipe joints, external water pipe easily dew condensation, accumulated more later dropped to the ground, do not worry there is water Leaking place. If you are concerned about this, then open the air conditioning to reduce the room temperature or dehumidification can avoid dew.
