Instructions for use of the enclosed cooling and heating circulator of LNEYA, a chiller manufacturer

In the chemical and pharmaceutical field, the closed cooling and heating circulator is a cooling and heating temperature control device that cooperates with various types of reactors, jacketed tanks, reactors, extraction equipment and other equipment. It can realize cooling and heating on the same machine. Its structure is reasonable and the operation is simple. , Stable performance, widely used in pharmaceutical, chemical, scientific research, biology, laboratory, environmental protection and other industries.

Airtight cooling and heating circulators can generally be divided into air-cooled and water-cooled. From the structure point of view, the entire circulation system is airtight and leak-free. Among them, the liquid circulation is a closed system, which can achieve no water vapor absorption at low temperatures and no oil mist generation at high temperatures. The expansion vessel and the liquid circulation are insulated and do not participate in the liquid circulation. Therefore, the closed heating and refrigeration integrated machine can play an important role in the fields with high cleanliness requirements such as pharmaceuticals and chemical industries.

In recent years, with the rapid development of China's pharmaceutical and other industries, hermetic cooling and heating circulators have also ushered in a better market prospect. And in terms of market conditions, the strength of domestic closed cooling heating circulators should not be underestimated. More and more manufacturers are emerging, launching different models of equipment to meet the needs of the domestic market.

For example, the hermetic cooling and heating circulator developed by Wuxi Guanya (LNEYA) uses branded compressors, which can ensure long-term stable and reliable operation of the unit, while providing excellent cooling effects. The electrical parts use good brand products, which are stable and have a long life. For a long time, the microcomputer full-function control operation panel is simple and quick, and the interface is friendly and more user-friendly. And the product is specially designed for appearance, beautiful and simple, and good quality.

In addition to the product quality of the closed cooling heating circulator itself, purchasing reasonable and formal equipment is the step to ensure that the equipment plays a good role. For example, when purchasing, the user needs to pay attention to whether the upper and lower temperature limits, ignition point, viscosity, freezing point, etc. meet the requirements, and whether it is suitable for the use of the internal pipeline of the instrument; when selecting the heat transfer medium pipe of the equipment, the length should be as short as possible, and the diameter should be as short as possible. As large as possible. The technician pointed out that if the diameter is too small, it may cause slow speed.

At the same time, the technicians also reminded not to use water as a heat transfer medium, otherwise it may have a negative impact on the closed cooling and heating circulator, and may cause damage to the equipment. It is recommended to use the heat transfer medium specified by the manufacturer and use it within the specified pressure range.
