Installation & Commissioning; Recommended System Layout - Parker DME012 Manual De Instrucciones

3 Installation & Commissioning
Only competent personnel trained, qualified, and approved by Parker domnick hunter should perform installation,
commissioning and service procedures.

3.1 Recommended system layout

The dryer should be installed with the correct pre-filtration and condensate management equipment to meet both the specification and local
environmental requirements.
Referring to diagram A4 in Annex A, the following equipment is recommended to meet these requirements:
Ref
1 Compressor
2 Wet air receiver
3 * General purpose filter (AO Grade)
4 * High efficiency filter (AA Grade)
* These filters may not have been supplied with the dryer but are essential in order to achieve the ISO classifications stated below.
3.1.1 Air Quality
A dryer operating with a pressure dewpoint of -40
can achieve ISO 8573.1:2010 Class 2.2.2
o
The optional -70 C dryer installed with the above filtration can achieve ISO 8573.1:2010 Class 2.1.2
ISO 8573.1:2010 is an international standard that specifies the purity classes of compressed air with respect to solid particulates, water and oil.
ISO 8573.1:2010 class 2.2.2 equates to the following:
Class 2 (Solid Particulate)
In each cubic metre of compressed air, not more than 400,000 particles in the 0.1 - 0.5 micron size range are allowed.
In each cubic metre of compressed air, not more than 6,000 particles in the 0.5 - 1 micron size range are allowed.
In each cubic metre of compressed air, not more than 100 particles in 1 - 5 micron size range are allowed.
Class 2 (Water)
o
A pressure dewpoint of -40 C or better is required.
No liquid is allowed
Class 2 (Oil)
In each cubic metre of compressed air, not more than 0.1 mg of oil is allowed.
Note: This is the combined level for aerosol, liquid and vapour.
ISO 8573.1:2010 class 2.1.2 equates to the following:
Class 2 (Solid Particulate)
In each cubic metre of compressed air, not more than 400,000 particles in the 0.1 - 0.5 micron size range are allowed.
In each cubic metre of compressed air, not more than 6,000 particles in the 0.5 - 1 micron size range are allowed.
In each cubic metre of compressed air, not more than 100 particles in 1 - 5 micron size range are allowed.
Class 1 (Water)
o
A pressure dewpoint of -70 C or better is required.
No liquid is allowed
Class 2 (Oil)
In each cubic metre of compressed air, not more than 0.1 mg of oil is allowed.
Note: This is the combined level for aerosol, liquid and vapour.
