Auto Electric Heated Tower Dryer Micro Computer Control Inlet Temperature 0-45℃

Features of Externally Heated Regenerative Desiccant Industrial Air Dryers :

Externally heated Purge Desiccant Air Dryer is a new economic product developed by our company; This series product integrating advantages of heat-exists purge and heatless purge, externally heating the purge air, reduce it's consumption.

Adsorption Element

Externally Heated Desiccant Air Dryer is integrated the advantages of PSA(Pressure Swing Adsorption) & TSA(Temperature Swing Adsorption).Absorbing during normal temperature and dense water vapour; purging during relatively high temperature and less density of water vapour. That’s to say, absorb water of sorbet, purify during the purging period by superior purge air of thermal diffusion and high pressure difference.

The Flow Chart of Externally Heated Purge Desiccant

Heatless Purge Desiccant Air Dryer using micro holes in the desiccant itself, adsorbing the moisture in the air because of capillary, desorbing it by pressure drop and adsorbing extra-heat. Currently, the equipment is making up of two towers, controlled by the Program Controller, the two towers working alternately, one is for adsorbing, the other is for desorbing, in this way continually circulating the work.

Why use a compressed air dryer?

As the name implies, air dryers are used to dry the compressed air: they remove moisture from the air, resulting in dryer air. This way, your valuable tools and machinery are protected from water and rust. But also your piping used to transport the compressed air is protected.

Water? Where is it coming from?

Compressors suck in lots of air and compress it to about 7 times the volume (that is, 7 bar pressure). The air that is sucked in always contains a little (or a lot!) water.

While the air can be compressed, the water cannot!

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.
