1.5 OVERLOADING
Attention!
Protect the adsorption dryer from overloading!
The adsorption dryer can become overl oaded if:
The flow volume of the medium to be dried increases
The temperature of the air at entry and, correspondingly, its
humidity increases
The minimum operating pressure decreases
The prefiltration and separation of impurities are not sufficient or the
filter drain fails
Introduction of oil into the air stream.
1.6 TRANSPORT
Immediately upon delivery of the dryer, it must be checked for any damage that may
have occurred during transport. If necessary, the damage must be recorded on the
shipping waybill/receipt.
Liability for such damage usually rests with the shipper.
Contact Sullair to arrange for any required service or replacement parts.
Attention!
For transport within your company site, only the skid of the adsorption
dryer may be used for lifting. Lifting at any other points on the equipment
will void the warranty and damage the equipment.
1.7 STORAGE
If the adsorption dryer is to be stored for a long period of time, its place of storage must
be dry and free of dust. The ambient temperature must not go below 33°F (+1°C).
1.8 USE OF A PREFILTER AND AFTERFILTER
In order to prevent droplets of condensate, oil and dirt from getting into the desiccant, a
Sullair SCH 0.01-micron coalescing prefilter with an automatic condensate drain must
be installed upstream of the adsorption dryer. Otherwise an oil film on the desiccant
would reduce the drying capacity and adversely affect performance.
In order to prevent breakdown in downstream consumers caused by material that has
been abraded from the desiccant bed, a Sullair SCR 1-micron particulate afterfilter must
be mounted downstream of the adsorption dryer. Since no condensate accumulates in
the afterfilter, this filter is normally equipped with a manual vent valve.
