Reference Description
2 Compressed air pipes
All pipes should be installed stress free to the dryer unit.
All pipes should be installed so that there is no
obstruction accessing the unit when the panels are
removed.
The inlet pipe orientation must be straight or with a 90°
upward bend to ensure equal air flow to all internal heat
exchangers.
The compressed air pressure should never exceed the
dryer's design pressure. It is recommended to install a
full flow safety valve at the dryer inlet.
The maximum total pipe length (including
interconnecting piping between dryer and receiver) can
be calculated as follows:
• Δp = ( L x 450 x Qc ) / ( d x p )
• L = length of pipe (m)
• Δp = pressure drop (recommended maximum = 0.1
bar / 1.5 psi )
• d = inner diameter of pipe (mm)
• p = absolute pressure at dryer outlet (bar(a))
• Qc = Free air delivery of the compressor (l/s)
3 Filter (optional)
It is recommended to install a compressed air filter at
the dryer inlet to achieve air purity class: ISO 8573 - 1 :
2010 [2 : - : - ].
The air filter has to be supported and can't be mounted
to the dryer directly without extra supports.
4 Air receiver (optional)
Should be installed in a frost free room on a solid, level
floor.
The preferred position is where the air flow fluctuates
the most:
• Alternative 1 (6): In front of the dryer when the air
flow from the compressor fluctuates the most.
• Alternative 2 (7): Behind the dryer when the air
demand fluctuates the most.
