1.4.5. Transport
After the adsorption dryer has been delivered, it must be checked for damage that may
have occurred during transport. Any damages should be reported immediately to the
transport company to begin the claim process.
☛ Note
For lifting and transportation, only the skid of the dryer may be used.
Do NOT support the dryer by the interconnecting piping any other
attached component.
1.4.6. 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. There has to be a minimum ambient temperature of 33°F (+1°C).
1.4.7. Use of a Pre and After Filter
In order to prevent droplets of condensate, oil, or dirt from getting into the desiccant, a
Sullair MPH pre-filter must be installed up stream of the adsorption dryer. Without proper
pre-filtration an oil film will build up on the desiccant reducing it’s drying capacity and
degrading performance. In order to prevent a damage to downstream components by
activated alumina dust (caused by abrasion of the desiccant bed), a Sullair MPR after-filter
must be mounted immediately downstream of the adsorption dryer. Since no condensate
should accumulate in the after-filter, this filter is normally equipped with a manual valve.
Both filters are normally equipped with a differential pressure gauge as this provides an
indication of the degree of contamination of the filter elements, and when the elements
should be replaced.
