Air Compressors and Dryers (Modified Package)

The air compressors were modified to meet hazardous area requirments by packager, the electrical and instrument equipments were changed and adding some enclosures, glands and cables.

Unfortuntely there were solenoid valves of dryers were burnt, only coils changed and valve bodies existed, the coil energy does not enough to push and pull then heat up at coils and also DO of PLC were burnt.

The new solenoid valves were replaced, rewiring and adding interposing relays.

The customer must be carefully design review and testing to ensure the modifiled that works properly.

The brass pressure safety valves supplied from manufacture also obstructed so it must be cleaned and tested after mechanical completion. 

The process instrumentation were mounted on enclosure that is easily to vibration.

  By changing motor to comply the hazardous area then motor dimension required more room to install.
