Functional description
Drying systems with refrigeration cycle have been designed for a cost effective elimination, with
minimal overall dimensions, of the condensate contained in compressed air by cooling it down to
approximately + 3°C.
The operation principle of the dryers described in this manual is shown in the air and refrigeration
circuit diagrams (attachment A).
The air delivered to the services is virtually humidity free, and the condensate collected in the
separator is discharged through appropriate draining devices. In order to limit the size of the
machine and to avoid condensation on the external surface of the tubing, before exiting the dryer,
treated air is counter current pre-heated by the air entering the system.
The dryer comes provided with all the control, safety and adjustment devices, therefore no
auxiliary devices are needed.
A system overload not exceeding the maximum operative limits can worsen the operational
performances of the dryer (high dew point), but it will not affect its safety.
The electric diagram (attachment B) shows the minimum protection degree IP 42. The user
must provide the dryer with a line protection and a ground terminal.
6.1.2
Use of the machine in safe conditions
This system has been designed and manufactured in compliance with the European safety
directive in force, therefore any installation, use and maintenance operations must be performed
respecting the instructions contained in this manual.
Any installation, use and maintenance operation requiring to access the internal parts of
the dryer must be performed by qualified personnel.
The manufacturer will not be liable in case of uses different or nor complying with those
foreseen in this manual.
In order to use the compressor in complete safety read the safety standards
given in section 1.3. before reading this section.
