Shanghai Haozhuang Instrument Co., Ltd. developed the LNB brand low-temperature constant temperature circulator, which is energy-saving and environmentally friendly, leading the country. Low-temperature constant temperature circulators are widely used in petroleum, chemical, electronic instruments, physics, chemistry, biological engineering, medicine and health, life sciences, light industrial food, physical property testing and chemical analysis and other research departments, colleges and universities, enterprise quality inspection and production ， Provide a field source with controlled heat and cold, uniform and constant temperature for the user when working, perform constant temperature test or test on the test sample or the product produced, and can also be used as the heat or cold source for direct heating or cooling and auxiliary heating or cooling .
Product description The cryostatic circulator is a high-precision constant temperature source with refrigeration and heating. It can be used for constant temperature experiments in the water tank in the machine, or connected with other equipment through a hose, and used as a constant temperature source. It is widely used in research departments such as petroleum, chemical industry, electronic instruments, physics, chemistry, biological engineering, medicine and health, life science, light industry food, physical property testing and chemical analysis, colleges and universities, enterprise quality inspection and production departments, working for users It provides a cold and controlled field source with uniform temperature and constant temperature. It can conduct constant temperature test or test on the test samples or products produced, and can also be used as a heat or cold source for direct heating or cooling and auxiliary heating or cooling.
Product Features â— Fully enclosed compressor unit refrigeration, the refrigeration system has multiple protection devices for overheating and overcurrent.
â— The circulating pump can lead the liquid in the tank to be a constant temperature liquid to establish a second constant temperature field.
â— The cold liquid in the tank can be led out, and the experimental container outside the cooler can also be used for low temperature and constant temperature experiments directly in the tank. â— It adopts an analog and digital automatic control system and the temperature is digitally displayed.
â— The inner tank and the table are all stainless steel, which is clean, hygienic, beautiful and corrosion-resistant.
â— The DCW series is horizontal type, which is convenient to be placed in the super workbench.
Internal operation principle 1. Low temperature constant temperature circulator components: compressor, condenser, evaporator, fan (inner and outer) circulating water pump, stainless steel liner, heating tube, intelligent temperature control meter.
2. The internal operating principle of the low-temperature circulator: after the compressor is operated, it is vaporized by suction-compression-exhaust-condensation-throttling-and then low-temperature evaporation heat absorption. The water temperature is reduced to the temperature set by the temperature control table, such as temperature The set temperature of the control meter is higher than normal temperature. The contactor in the temperature control meter works automatically, giving the heating tube a current signal, and the heating tube starts to work when working in the low temperature thermostat. The inlet and outlet of the whole machine can be used for internal circulation or external circulation of the internal water source, and the internal water source can also be led out. Do the second constant temperature field outside the cryostat.
