Physicochemical fields: lasers, magnetic fields, various molecular pumps, diffusion pumps, ion pumps, and materials. A variety of water-cooling equipment used.
Product advantages: Energy saving - Cooling water can be recycled in the system loop during summer and high ambient temperatures, saving a lot of water resources. More efficient – ​​a circulating water unit can meet the cooling needs of multiple external equipment at the same time, providing a constant temperature source for condensation experiments. Temperature control accuracy - PID temperature control technology, built-in PT100 sensor, high temperature control accuracy, temperature digital display, intuitive operation, high safety - self-diagnosis function; freezer overload protection and other security functions. Low temperature antifreeze solution A solution of ethylene glycol: ethylene glycol / water 55 / 45 (-30 ° C), 70 / 30 (-40 ° C) B glycerol aqueous solution: glycerol / water 70 / 30 (- 30 ° C) In use, it is necessary to check the density of low temperature antifreeze to meet the following requirements: 1. Aqueous solution of ethylene glycol: P20 = 1079 kg / m3 (-30 ° C) (-40 ° C) 2. Aqueous glycerol solution: When P20=1182.6kg/m3 (-30°C), the minimum temperature of the antifreeze must be above 0°C. Cooling water selection: Generally, small-circulating water cooling thermostats with a cooling capacity of less than 1000W are widely used in laboratory condensing devices such as low-power lasers, parallel evaporators, parallel quantitative concentrators, parallel reactors, and distillation meters. Medium-sized circulating water cooling thermostats with a cooling capacity of less than 6000W are widely used in analytical instrument industries such as AAS, ICP, ICP-MS, and electron microscopy, and laboratory equipment such as rotary evaporator, Soxhlet extraction, solid-liquid extraction, and Kjeldahl analyzer. , laser marking machine, laser cutting machine and other laser instruments and machine tool industry. Large circulating water cooling thermostat with refrigeration capacity above 10KW is widely used in X-ray diffractometer, magnetic mass spectrometer, fatigue testing machine, vacuum coating machine, plastic forming equipment, laser cutting machine, X-ray fluorescence spectrometer, infrared spectrometer, differential thermal analysis. Instruments, nuclear magnetic resonance and other equipment with high refrigeration constant temperature requirements.
