Why dry compressed air?
The air we breathe contains contamination
in the form of water vapour and airborne
These problems can be avoided with
the correct selection and application
of compressed air filters and dryers
During the compression process an air
compressor concentrates these contaminants
and depending on the design and age will
even add to the contamination in the form
of oil carry over.
Modern air compressors generally have built
in aftercoolers that reduce the discharge
temperature of the compressed air and with
the help of water separators, remove the bulk
of liquid water.
In some applications this may be sufficient,
but the remaining dirt and moisture content
suspended in aerosol form, can, if not
removed, damage the compressed air system
and cause product spoilage.
Spoiled paint finish
The result - higher overall cost of operation
■ Increased system downtime
Reduced production efficiency

Refrigeration Dryers are available in 5 model
sizes to suit all applications. When installed
with compressed air filters they will provide
clean compressed air to the classes as
prescribed in ISO 8573.1.

Air quality - With correct selection, the above
schematic relates to an installation that would
provide Class 1 dirt, Class 4 water, and Class 1
oil. This is recommended to stop downstream
corrosion, prevent product spoilage and
prolong the life of pneumatic tools and the
compressed air system.
A Look Inside
All models feature a low pressure drop
pre-filter on the air inlet.
This feature keeps the heat-exchanger
clean and reduces maintenance
The oversized demister separator offers an
exceptional condensate removal rate with
lowest pressure drops.
Unlike centrifugal systems, the demister
works equally well at partial air flow
conditions, ensuring the dew point is
maintained under all conditions.
The standard shell-&-tube
ensures extremely low water
side pressure drops and
requires minimal maintenance.
Air-cooled versions are also
ThermoStar Large’s innovative
tandem scroll compressors
(standard up to 225m 3 /min) offer
numerous real customer benefits,
including: significantly reduced
power consumption; real 50%
energy savings at partial load as
one compressor switches off
(unlike typical solutions); longer
compressor life; elimination of the
need to pre-heat the dryer; no risk
of compressor damage caused by
liquid returns; full stand-by facility
as one compressor still runs if the
other shuts down.
With ThermoStar Large sophisticated
design solutions lead to real advantages
for the user.
Thermostar Large's heat exchanger has
a very innovative patented design. The
single vessel configuration is extremely
compact, saving valuable factory space.
The notably simplified air circuit reduces
the number of welds to a minimum, for
improved longevity and reliability.
The implementation of quality materials,
specifically treated, ensure TSL
withstands even the most rigorous
industrial conditions. A combination of
top dew point performance levels and
minimal air pressure drops are obtained
thanks to generous dimensioning,
minimal air turns and performance
enhancing “trifoglio” tube inserts.
ThermoStar Large features an advanced
microprocessor control as standard. The dew
point is continuously digitally displayed.
All functions are fully programmable, giving
the user full control over dryer operation. A
working hour counter and programmable
service interval monitoring facility simplify
A status report lists the 8 most recent
occurrences, whilst a secondary report
memorises all sensor readings at alarm
intervention, for easy fault diagnosis.
The comprehensive set of alarms can be
user-programmed, and on intervention they
provide easily understandable written text
messages. A general alarm volt free contact
is also supplied.
