Why compressed air purification?

Compressor alone is not enough.In most cases,untreated compressed air is naturally dirty,oily and wet.This condition is certainly notdesirable for industrial applications and could directly or indirectlylead to the following situations.

• Reduction in efficiency of expensive pneumatic tools & machineries

• Frequent costly maintenance of pneumatic tools & machineries

• Lost of production hours with increased machines down time

• High rejection rate of products

• Inability to meet delivery deadlines

• Unsatisfied customers

How to get compressed air with very low dew point?

The dew point of the compressed air after being treated by the cold dryer can be around -20 ° C (normal pressure), and the dew point can be processed by the adsorption dryer to reach the range above -60 ° C. However, some industries that require extremely high air dryness (such as the microelectronics industry require a dew point of -80 °C) are obviously not enough.

Nowadays, the method promoted by the technical community is that the cold dryer is connected in series with the adsorption dryer, and the cold preheater is used as the pre-treatment equipment for the adsorption dryer,

so that the moisture content of the compressed air is greatly reduced and then enters the adsorption dryer. Get compressed air with very low dew point.

Moreover, the lower the temperature of the compressed air entering the adsorption dryer, the lower the dew point of the compressed air finally obtained.

According to foreign data, when the inlet temperature of the adsorption dryer is 2 °C, the molecular sieve is used as the adsorbent, and the dew point of the compressed air can reach below -100 °C. This method has also been widely adopted in China.

Shanghai Rotorcomp Screw Compressor Co., Ltd  founded in 1999, our company was a manufacturer of piston air compressors from 1985-1999. After 2000 our company headquarters moved to the international metropolis Shanghai and focused on screw air compressors, pressure vessel, refrigeration dryer, adsorption dryer and air filters with the support of Rotorcomp Verdichter Gmbh in German.

Shanghai Rotorcomp Screw Compressor Co. Ltd., Shanghai Ziqi Container Co.Ltd. have been cooperated with 2010 Beijing Nankou Railway Transit Machinery Co. Ltd., which belongs to China CNR Corporation Limited, as the strategic cooperation partner.

The Beijing Nankou company has processing equipment more than 100 sets, including large-scale precision equipment 90 sets and imported equipment 70 sets. Such as Hardinge double-ended grinder, Toshiba horizontal machining center, BW CNC vertical and horizontal machining center, Holroyd rotor profile grinder and Zeiss 3D measuring machine.

From 2017, we successfully develop the new generation oil-free air compressors with the ISO9001 certificate, ISO14001 certificate, energy-saving product certificate, OSHAS (Occupation Safety and Health management System) certificate, vonTUV certificate and CE Certificate. According to the Standard European Din40080, our air end and air compressors have won the praises of the customers over 45 countries worldwide.

Followed the principle and policy of " First-class Quality, First-class Service" Shanghai Rotorcomp insists on improving ourselves into a first-class supplier for the air compressor.
