the ma hine.
Models:
• Standard (“S” models)
• Refrigerated (“R” models with pre- ooling oil)
Drying units with “ Heat - Less “ working pro ess use hemi al-physi s property of drying materials to adsorbing humidity from air and
expelling it during regeneration phase. The regeneration is performed with draining of a small part of dried air, olle ted from outlet,
whi h removes humidity from the exhausted adsorbing bed dis harging it into atmosphere.
The plant (see s heme) mainly onsists of two adsorbers whi h ontain harge of drying material.
Inside the adsorbers stainless filter are provided to retain eventual solid impurities out oming.
The valves fore ast for the different automati fun tions, are suitable for heavy ontinuous operation.
No parti ular maintenan e or lubrifi ation are ne essary on the valves.
The ontrols are performed by solenoid valves whi h drive the valves.
The ontrol logi is ele troni and ompletely automati .
The ma hine has a light swit h for starting and stopping.
Performan e and spe ifi ations shown in the following atta hments:
•Data sheet
•Wiring diagram
2.0 INTENDED USE
These dryers have been developed to automati ally eliminate the moisture ontained in ompressed air or an inert gas. Adsorbent
material dries the air passing through one of the two pressure vessels. Simultaneously, the other pressure vessel is regenerated by
purging a small volume of the dried air from the outlet of first pressure vessel.
The ompressed air / gas supplied by the dryer annot be used for breathing air, pharma euti al or sanitary purposes or in produ tion
plants where the output air omes into dire t onta t with foodstuff, unless an additional air treatment system is employed, whi h is
spe ifi ally designed for this purpose.
The dryer is not suitable for use in "explosion or hazardous" environments.
The Manufa turer is not responsible for any use other than the intended use, or for operation, whi h is not in omplian e with the
instru tions in this manual.

The ma hine is designed solely to dry ompress ed air or inert gas and annot be used for any other type of gas.
The ompressed air inlet to the dryer must be absolutely free of dust, vapors, explosive or flammable gas, solvents and toxi fumes of
any kind. Use of ompressed air or inert gas requires knowledge of, and omplian e with the safety pre autions to be adopted for the
individual appli ations.
WARNING : Before starting the ma hine, make sure that all guards are orre tly fitted and that no-one an be dire tly or indire tly
injured by the sudden flow or ompressed gas within the pipework system without noti e.
Dryer operation is automati .
Remember that ompressor oil, ondensate and the filter element are pollutants. Dispose of these produ ts
in omplian e with lo al legislation.
4.2 SAFETY PRECAUTIONS FOR MAINTENANCE OPERATIONS
Skilled operators must perform all maintenan e.
• Dis onne t the power supply and depressurize the dryer performing any servi e operation.
• After dis onne ting the power, lo k out the ir uit breaker to prevent a idental start-up. Isolate the dryer from the ompressed air
system losing the input valve.
• All ompressed air has been dis harged from the dryer only when pressure gauge shows zero pressure.
• No hanges must be made to dryer’s internal ele tri al or pneumati ir uits and/or to the fa tory settings.
• Do not use solvents, flammable or toxi fluids to lean the dryer parts. Never use detergents to lean the ele tri al/ele troni s
omponent.
• Do not weld or arry out me hani al ma hining operations on the pressure vessels. If damaged or rusted, repla e the parts, as they
subje t to spe ifi regulations.
• At the end of ea h operation, refit the guards arefully.
