1.0 PERFORMANCE AND SPECIFICATIONS

This machine has been designed and realized in compliance with U.S.A. regulations. A plate indicating the specifications is applied to
the machine.
Models:
• Standard ("S" models)
• Refrigerated ("R" models with pre-cooling coil)
Drying units with " Heat - Less " working process use chemical-physics 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, collected from outlet,
which removes humidity from the exhausted adsorbing bed discharging it into atmosphere.
The plant (see scheme) mainly consists of two adsorbers which contain charge of drying material.
Inside the adsorbers stainless filter are provided to retain eventual solid impurities outcoming.
The valves forecast for the different automatic functions, are suitable for heavy continuous operation.
No particular maintenance or lubrification are necessary on the valves.
The controls are performed by solenoid valves which drive the valves.
The control logic is electronic and completely automatic.
The machine has a light switch for starting and stopping.

2.0 INTENDED USE

These dryers have been developed to automatically eliminate the moisture contained in compressed 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 compressed air / gas supplied by the dryer cannot be used for breathing air, pharmaceutical or sanitary purposes or in production
plants where the output air comes into direct contact with foodstuff, unless an additional air treatment system is employed, which is
specifically designed for this purpose.
The dryer is not suitable for use in "explosion or hazardous" environments.
The Manufacturer is not responsible for any use other than the intended use, or for operation, which is not in compliance with the
instructions in this manual.
