Air dryers repairs

Atmospheric air always contains moisture: the higher temperature, the higher humidity is typical for the air. However, when compressed air is accumulated moisture, the water is condensing on the internal parts of the equipment and pneumatic systems. It is the case of corrosion and reduce the equipment lifetime. Therefore usually the additional air treatment equipment, like air dryer are used to avoid the accumulation of moisture in the pneumatic system.

Desiccants for Absorption air dryer

Activated alumina/Desiccant beads have a white, spherical, non-toxic, odorless, insoluble in water and alcohol. They are able to stand out thermal shock and abrasion with highly mechanical stability and strong absorption (impervious). The particle shape does not expand or crack after absorbing.

Maintenence chedule of desicant air dryer (heatless type)

Compressed air system in factory plays an important role. In order to ensure the stable operation during the manufacturing process, the regulary maintenance is nescessary . However, there are many different problems in fact such as: Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduce using time of compressor accessories (air filter, oil filter, oil separator ...). On the other hand, the recommended maintenance in some factories is not seriously followed and there are deviations. To extend the life of the machine as well as compressor components and ensure operator safety Air compressors are very important to maintain regularly and technically correct.Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduced use time of compressor accessories (air filter, loc oil, oil separator ...). On the other hand, the maintenance (maintenance) recommended by the manufacturer in some factories is not guaranteed and there are deviated. To lengthen longevity of mạchine as well as compressor components and ensure operator safety , air compressors are very important to maintain regularly and technically .

 The faults and problems in the air end operation effect on the whole compressor, on energy consumption, main parameters of the compressor, operational temperature etc.

Wiring for remote operation of Handsome II air compressor

The compressor can be operated remotely with the LOCAL/REM selector switch on the meter panel. For the remote operation, the following wiring work is required. Before wiring, be sure to turn off the main power and make sure that no electric power is supplied to the compressor.
