Product advantages: Energy saving-In summer and high ambient temperature, cooling water can be recycled in the system circuit, saving a lot of water resources. Higher efficiency-one circulating water device can meet the cooling needs of multiple external devices at the same time, and continuously provide low-temperature and constant-temperature water sources, suitable for condensation experiments. Temperature control accuracy-PID temperature control technology, built-in PT100 sensor, high temperature control accuracy, digital temperature display, intuitive operation, high safety-with self-diagnostic function; freezer overload protection and other safety guarantee functions. Proportion of low temperature antifreeze liquid A glycol aqueous solution: ethylene glycol / water 55/45 (-30 ° C), 70/30 (-40 ° C) B glycerol aqueous solution: glycerin / water 70/30 (- 30 ℃) The density of low-temperature antifreeze should be checked frequently during use to meet the following requirements: 1. Ethylene glycol aqueous solution: P20 = 1079㎠/ m3 (-30 ° C) (-40 ° C) 2. Glycerin aqueous solution: P20 = 1182.6㎠/ m3 (-30 ℃) When the antifreeze is replaced with water, the minimum temperature must be above 0 ℃. Cooling water type selection: Generally, small-scale circulating water cooling thermostats with cooling capacity below 1000W are widely used in laboratory condensing devices such as low-power lasers, parallel evaporators, parallel quantitative concentrators, parallel reactors, and distillers. Medium-sized circulating water-cooled thermostats with a refrigeration capacity below 6000W are widely used in analytical instruments such as AAS, ICP, ICP-MS, and electron microscopy. Rotary evaporators, Soxhlet extraction, solid-liquid extraction instruments, Kjeldahl nitrogen analyzers and other laboratory equipment , Laser marking machine, laser cutting machine and other laser instruments and machine tool industries. Large-scale circulating water-cooled thermostats with a refrigeration capacity of more than 10KW are widely used in X-diffraction instruments, magnetic mass spectrometers, fatigue testing machines, vacuum coating machines, plastic forming equipment, laser cutting machines, X-fluorescence spectrometers, infrared spectrometers, and differential thermal analysis Instruments, nuclear magnetic resonance and other equipment with high refrigeration constant temperature requirements.
