Magnetic Levitation Chillers have developed from the relatively lower temperature control accuracy of ordinary constant temperature baths. It can only heat but not cool, thus it can only provide accurate temperature control above room temperature. Generally, the temperature is below 300℃, and it is available in 6-liter and 15-liter series. Due to the difference in temperature, it is also called a water tank or an oil tank. It is widely used in fields such as fine chemicals, bioengineering, metallurgy, petroleum, and agriculture. It provides users with high-precision constant temperature field sources and is an ideal constant temperature equipment for research institutes, universities, laboratories of industrial and mining enterprises, and quality inspection departments.
The precision constant temperature bath and the low-temperature constant temperature circulation bath are equipped with temperature control probes and other accessories inside. These accessories will transmit the information inside the bath to the control part of the low-temperature constant temperature circulation bath. Timely cleaning of these stains can effectively and accurately transmit signals, reducing signal errors caused by the adhesion of stains and mistakenly putting the compressor in a full pressure refrigeration state. During the experiment, it is necessary to pay attention to the fact that the container of the experiment or the high-concentration liquid is squeezed or accumulated at the outlet of the circulating pump and the temperature control probe to avoid inaccurate temperature caused by squeezing and accumulation. Preparations before using the low-temperature constant temperature bath: During the first use, if external circulation operation is required, the low-temperature constant temperature bath should be connected to the system used in the experiment. Connect the inlet and outlet liquid ports of the equipment with the inlet and outlet liquid ports of the experimental instruments with insulated flexible hoses to form a closed circulation. When conducting experiments in the tank, it is necessary to connect the inlet and outlet of the low-temperature constant temperature tank through insulated hoses to form a closed circulation. Remove the upper cover, add water or non-freezing liquid, and the liquid should submerge the heating tube and the evaporation tube. Turn on the power of the device and set the required temperature.
Daily maintenance and care:
Before use, liquid medium needs to be added to the low-temperature constant temperature bath first; otherwise, the heater will be damaged when powered on and working. The liquid level of the medium should be about 30mm lower than the workbench plate.
2. The selection of liquid medium in the low-temperature constant temperature bath should comply with the following principles:
a. When the working temperature is between 5 and 85℃, water is generally selected as the liquid medium.
b. When the working temperature is between 85 and 95℃, a 15% glycerol water solution can be selected as the liquid medium.
c. When the working temperature is below 5℃, alcohol or refrigerant is generally selected as the liquid medium.
After the refrigeration switch of the low-temperature constant temperature bath is turned off, there should be an interval of 10 to 20 minutes before turning it on again (depending on the ambient temperature).
4. Power supply for low-temperature constant temperature bath: 220V50Hz. The power of the power supply should be greater than the total power of the instrument. The power supply needs to have a good "grounding" device.
5. The low-temperature constant temperature bath should be placed in a dry and well-ventilated area, with no obstacles within 300mm around the instrument. When the working temperature of the low-temperature constant temperature bath is relatively low, be careful not to put your hands into the bath to prevent frostbite.
After the constant temperature bath is used, all switches should be turned off and the power supply should be cut off.
7. The low-temperature constant temperature bath should be regularly cleaned to keep the work surface and operation panel clean and tidy.
Magnetic Levitation Chillers does not hesitate to use refurbished compressors as new ones, which is difficult for ordinary users to distinguish. If a low-temperature constant temperature bath with a refurbished compressor is purchased, it will cause a decrease in energy consumption ratio, unstable performance, and even the compressor will be scrapped quickly, affecting production and causing greater losses. The compressor of the Zhixin ZX series low-temperature constant temperature bath adopts imported compressors. Some users choose machines blindly in pursuit of price, but they overlook the more important mission of the low-temperature constant temperature bath, which is to ensure the reliability and stability of industrial production or experimental processes. It is true that at that time, the procurement seemed to have saved some costs, but in reality, the subsequent problems would be even greater. The resulting human resource consumption and production losses would far exceed the savings. The ZX series low-temperature constant temperature bath of Zhixin is moderately priced and of guaranteed quality. The configuration of the unit varies greatly in some low-temperature constant temperature baths. Take water pumps for example. Stainless steel water pumps are definitely more durable and reliable than ordinary cast pumps, and they are also beneficial to water quality and other aspects, thereby protecting the cleanliness of the pipelines inside the main unit and ensuring better performance of the main unit.
