The life of most refrigeration systems depends on when the refrigerant leaks. The leakage of refrigerant is caused by the reaction of the refrigerant and the trace water contained in it, which results in the corrosion of the pipeline. Molecular sieve of Dalian Haixin has the characteristics of low dew point, high strength and low wear, and has good compatibility with the refrigerant, and does not destroy the chemical stability of the refrigerant.

Dalian Haixin chemical refrigeration drying series of molecular sieve has been made compatible with most of the refrigerant quality inspection report, compatibility test by European Union and North America and 134a, the laboratory certification of 1234yf and oil, the ease of use.
1、Application of refrigeration desiccant
The main purpose of refrigeration desiccant is installed in the refrigeration system drying filter. The dry filter is an important component of the refrigeration system, its main function is to absorb the moisture in the circulating refrigerant, control the acid content, and filter the impurities in the refrigerant.
2、The advantages of Dalian Haixin ‘ products
The choice of molecular sieve is very critical:
1, molecular sieve in addition to the adsorption of water, does not adsorb refrigerant effective substances;
2, no chemical reaction between the refrigerant and molecular sieve, does not affect the chemical stability of the refrigerant;
3, dew point control requirements are particularly low;
4, high strength, low wear, and do not bring unnecessary gas;
5, high compatibility, with the vast majority of refrigerants and refrigeration oil market has a good compatibility, and through international certification.
Dalian Haixin chemical refrigeration desiccant has the following characteristics:
· Strong water absorption
Water absorption capacity can be said to be the most important performance index of refrigerant desiccant. The superior water absorption capacity can not only ensure the safety and reliability of the refrigeration system, but also prolong the service life of the filter.
· Adsorption and high acid content
Dalian Haixin chemical desiccant refrigeration process using the technology of Dalian Haixin chemical research and development center of the latest development, by comparison, Dalian Haixin chemical refrigeration drier than other similar products in addition to acid 22%. And in addition to the acid does not react with the refrigerant chemical reaction, will not have any effect on the chemical stability of the refrigerant.
· Low dew point and wear rate
If not very low dew point cooling desiccant, easily at low temperature condensation, have great influence on the refrigeration system; high attrition rate would make the short life of refrigeration and desiccant, residual impurities. The application of Dalian Haixin chemical independent research and development of new process, so that the cooling desiccant dew point than the market similar products to reduce a lot, wear rate is very low, the protection of the cooling system.
· High compatibility
Dalian Haixin chemical refrigeration desiccant widely used in various types of refrigerant and oil mixture, compared to other products applicable to a single type, Dalian Haixin chemical refrigeration desiccant and refrigerant more compatible.
