A full range of HPS (heatless
pressure swing) adsorption dryers
for compressed air systems is
available from Hi-line Industries.

Designed with simplified ‘plug and
play’ installation, they are reported to
combine high efficiency and
realiability with minimum running
cost.

The units operate at a pressure
range of 7-10 barg (min 4 barg), and
should not be confused with budget
versions using cheap shuttle valves
which can fail within a relatively
short time, says the company. They
are suitable for any commercial/
industrial application where high
quality dry air is required.

Stainless steel pipework and high
quality check valves help ensure
continuity of flow without dewpoint
spiking or pressure drop.
