Offered in three flow capacities, the
HPD range of ‘point of use’ dryers
from Hi-line Industries are
compact, cost effective and feature a
‘minimum downtime’ cartridge
change. They are suitable for remote
installations, or wherever there may
be only limited access available.

They provide generalised
protection for downstream airline
production equipment, as well as
many specialised requirements,
including instrument air quality,
printing and gas analysing devices,
and so on. The HPD unit provides a
localised installation where high
quality air is a critical requirement. It
ensures a low dewpoint (-40°C) at
point of use, or where an existing air
supply has only been dried to a
refrigerant air dryer quality of +3°C
dewpoint.

The dryer range uses a disposable
desiccant adsorption cartridge to
effectively remove moisture from a
compressed air supply. The special
housing design lets the cartridge be
changed within 2min, without the
need for any specialised tools. A
pressure dewpoint of -40°C can be
achieved with no energy consumption,
no power required and no air loss
from the use of purged air.
