The nitrogen booster compressor, employed by "Zhongsu Hengda," serves the purpose of pressurizing and facilitating the transportation or storage of nitrogen. Its primary applications include filling nitrogen cylinders with pressurized gas and conducting nitrogen pressure leakage tests on pipelines, among others. With a remarkable capacity, this compressor can achieve a maximum filling pressure of 40MPA. Based on the cooling technique employed, it is classified into two types: air cooling and water cooling.

Working principle：dryer
Use the refrigerant to exchange heat with the compressed air to lower the temperature of the compressed air to a dew point temperature in the range of 2 to 10°C.According to the cooling method of the condenser, the cold dryer is divided into two types: air-cooled type and water-cooled type. It consists of four parts: refrigeration compressor, condenser, evaporator and expansion valve.

When the compressor compresses the air to a certain pressure, it is delivered to the air storage tank.When the stored compressed air needs to be used, the air flows out from the air storage tank, and is transported to the required equipment or system through the discharge valve and pipeline. At the same time, when the compressed air in the air storage tank exceeds the set safety pressure, the safety valve will automatically open to release excess compressed air to avoid the danger of overload or explosion of the air storage tank.

It can filter oil mist and hydrocarbons as small as 0.01um, and the lowest residual oil content is only 0.003ppm.
Widely used in food, medicine, electronics, chemical industry, industrial waste water and other industries.

C-Class Main Line Filter：Used after the air compressor or before the refrigerated dryer, it can filter out solid particles above 3um and a large amount of liquid, and achieve the lowest residual oil content of only 5ppm.



T-Class Filter：Also known as air line filter.Used before the A-grade filters, it can filter out liquid and solid particles as small as 1um, and achieve the lowest residual oil content of only 0.5ppm.



A-Class Filter:Also known as ultra-high efficiency oil removal filter.Used after the refrigerated dryer, it can filter out liquid and solid particles as small as 0.01um, and the lowest residual oil content is only 0.001ppm.

P860 series analyzer is the online intelligent measurement instrument, which adopting advanced ion current oxygen sensor with single chip technology. N2%=100%-O2%. It has been widely used in the fields of nitrogen separation from air, fertilizer, petrochemicals and biological fermentation.

CI-PC36 dew point analyzer is an intelligent dew point analyzer with microprocessor as its core and ultra-thin alumina capacitive sensor as its measuring unit. It has the characteristics of high precision, good stability, comprehensive function and long service life.

CI-PC96 is a micro-oxygen analyzer, which is an intelligent analyzer based on microprocessor. The sensor used in this system is a fuel cell oxygen sensor, which can measure 0-25% oxygen concentration, but in the environment of 0-1000ppm oxygen concentration, the measurement is the best.

P950 Process Oxygen Analyzer is based on microprocessor, which is adopts the ion flow oxygen sensor as measuring unit. It will display oxygen concentration in oxy-nitride mixed gas after processing and calculating through microprocessor. There are a set of alarm point, a set of analog output signal and a set of on-off switch value for users.

Carbon molecular sieves are carbon adsorbents, which are porous materials composed of carbon. The pore structure model is disordered carbon accumulation structure. Carbon molecular sieves are non-quantitative compounds whose important properties are based on their microporous structure.

Zeolite can adsorb heavy metals in water. Adsorption phenomena can be divided into physical adsorption and chemical adsorption. For gas purification, it mainly relies on adsorption and exchange.

The working principle of dry adsorbed molecular sieve is mainly related to the pore size of molecular sieve, respectively 0.3nm/0.4nm/0.5nm, they can adsorb gas molecules whose molecular diameter is smaller than the pore size, and the larger the pore size, the larger the adsorption capacity.
