Shanghai Haozhuang Instrument Co., Ltd. has developed the LNB brand high-temperature circulator, which is energy-saving and environmentally friendly, leading the country. Professional manufacturing is more secure and affordable. Advantages and disadvantages of the sealed high-temperature circulator 1: Oil mist is generated at a temperature above 100 ° C. The higher the temperature, the more oil mist is generated, which is harmful to the human body and pollutes the laboratory environment. 2: The high-temperature oil expands when it exceeds a certain temperature, and the non-expansion container provides reflux, which causes the high-temperature oil to overflow, pollutes the laboratory environment, and sticks oil on the ground, which is easy to slip. 3: When the high temperature experiment, the temperature around the ordinary high temperature circulator is too high, especially above the high temperature circulator. 4: During the operation of the ordinary high-temperature circulator, the high-temperature silicone oil is all heated and participates in the cycle, and the power consumption is high; the high-temperature oil contacts the air and is easily oxidized, resulting in a decrease in the high-temperature silicone oil's performance. cost. If the high-temperature silicone oil is not replaced in time, the heater may burst. 5: Lower purchase cost. ? Fully enclosed high temperature circulator 1: No oil mist is generated in the full temperature range, keeping the laboratory environment clean and hygienic. 2: The high-temperature oil expands when it exceeds a certain temperature, and the expansion oil flows back into the expansion vessel to avoid the overflow of the high-temperature oil. 3: When the high-temperature experiment, the temperature of the silicone oil in the expansion vessel does not exceed 60 ℃, the thermal insulation performance is good, and the surrounding environment will not be too hot. 4: During the working process of the fully enclosed high-temperature circulator, the high-temperature silicone oil is partially heated and participates in a small amount of circulation to reduce power consumption and achieve energy-saving effects. Moreover, the high-temperature oil is not easily oxidized in the closed cavity, extending the service life of the silicone oil and saving 2 / 3 of the cost of use. 5: Higher purchase cost Weihai Tong Park Arts & Crafts Co.,Ltd , https://www.whtongpark.com
