Some attentions of desicant air dryer (heatless type) maintenence

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, in fact there are many different problems  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 operate safely 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 compress

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.

Working safely with compressed air tank

Safely using of compressed air tank is a very important issue, compressed air tank before being used must be tested by KTAT, registered for use following regulations. Users must hand over the managing responsibility the compressed air tank to the equipment manager in writing. Operating of thetanks is only given to people from 18 years old or older, who are physically fit and well-trained. They must be assigned by the employer in writing.

1. Pre-Operation of Handsome II air compressor

  • Are the air inlets on the left side face, the one on the right side face (only for dryer-intergrated types) and the outlet on the upper face not blocked?
  • Is the oil level normal? 

2. Meter Panel Meter Panel.

  • Selector switches.
  • Dryer continuation selector switch for emergencyThis is a switch to select whether the compressor is to be stopped or left to run when a failure occurs in the dryer. When the lamp is on, the compressor keeps running even if a failure occurs in the dryer. Changing the selection is possible only when the machine is stopped, this switch is provided for dryer-intergated types only. 

  • Local/Remote control selector switch: This is a switch to select whether the compressor is to be operated locally or remotely. The lamp is on when the local operation is selected. ( Changing the selection is possible only when the machine is stopped). 
  • POWER lamp (red): This lamp comes on when the breaker switch is turned on.

Step 4:  Press the START button (green) and check if the motor starts to run.

If the motor does not start, there may be a problem in wiring. Make sure that the motor starts to run and the pressure rises by the discharge pressure gauge. The compressor is unloaded when the pressure reaches 0.74 Mpa (7,5kgf/cm2) with u-type, and 0.88Mpa (9.0 kgf/cm2) with uH-type. 

  • Stopping.

Press STOP button (red), the compressor stops.
Turn off the earth leakage breaker switch.
