In case of heavily polluted inlet air (ISO 8573.1 class 3.-.3 or worse quality), we recommend
the additional installation of a pre-filter (5 micron minimum) to prevent a clogging of the
heat exchanger.

Type A installation is suggested when the compressor operates at reduced intermittence and the total

consumption equals the compressor flow rate.

Type B installation is suggested when the air consumption can consistently change with peak values highly
exceeding the flow rate of the compressors. The capacity of the tank must be sized in order to compensate
eventual instantaneous demanding conditions (peak air consumption).

Correction factor for DewPoint changes:
DewPoint ºC 3 5 7 10
Factor (F4) 0.91 1.00 1.10 1.26

How to find the air flow capacity:

Air flow capacity = Nominal duty x Factor (F1) x Factor (F2) x Factor (F3) x Factor (F4)

Example:

An AMD 18 has a nominal duty of 1800 l/min . What is the maximum allowable flow through the dryer under
the following operating conditions:

–

Inlet air pressure = 7 barg

–

Ambient temperature = 35°C

–

Inlet air temperature = 40°C

–

Pressure DewPoint = 3°C

–

Factor (F1) = 1.00

–

Factor (F2) = 0.95

–

Factor (F3) = 0.84

–

Factor (F4) = 0.91

Each item of data has a corresponding numerical factor which multiplied by the design air flow is as follows:

Air flow capacity = 108 x 1.00 x 0.95 x 0.84 x 0.91 = 1307 l/mi n

1307 l/min This is the maximum flow rate that the dryer can accept under these operating conditions.

How to select a suitable dryer for a given duty:

Design air flow

Minimum std. air flow rate =

Factor (F1) x Factor (F2) x Factor (F3) x Factor (F4)

Example:

With the following operating parameters:

–

Design air flow = 1100 l/m in

–

Inlet air pressure = 7 barg

–

Ambient temperature = 35°C

–

Inlet air temperature = 40°C

–

Pressure DewPoint = 3°C

–

Factor (F1) = 1.00

–

Factor (F2) = 0.95

–

Factor (F3) = 0.84

–

Factor (F4) = 0.91

In order to select the correct dryer model the required flow rate is to be divided by the correction factors relating
to above mentioned parameters:

1100

Minimum std. air flow rate =

1.00 x 0.95 x 0.84 x 0.91

= 1515 l/ min

Therefore the model suitable for the conditions above is AMD 18 (1800 l/ min - nominal duty).

2.6. CONNECTION TO THE COMPRESSED AIR SYSTEM

Operations to be performed by qualified personnel. Never operate with plants under pressure.
The user is responsible to ensure that the dryer will never be operated with pressure exceeding
the nominal values.
Eventual over-pressure could be dangerous both for the operator and the machine.

The temperature and the amount of air entering the dryer must comply with the limits reported on the data
plate. In case of treatment of air at particularly high temperatures, the installation of a final refrigerator could
result necessary. The cross section of the connecting piping, which must be free from dust, rust, chips and
other impurities, must be consistent with the flow-rate of the dryer.
In order to facilitate the maintenance operations, a by-pass group has been installed, as shown in the
following illustration.

In realising the dryer, particular measures have been taken in order to limit the vibration which could occur
during the operation. Therefore we recommend to use connecting pipes able to insulate the dryer from
possible vibrations originating from the line (flexible hoses, vibration damping fittings, etc.).

CAUTION:

PIPING THE DRYER, INLET/OUTLET CONNECTIONS MUST BE SUPPORTED AS
SHOW IN THE DIAGRAM.
FAILING WILL RESULT IN DAMAGE

2.7. ELECTRICAL CONNECTIONS

Qualified personnel should carry out connecting unit to the main power. Be sure to check the local
codes in your area.

Before connecting the unit to the electrical supply, verify the data nameplate for the proper electrical
information. Voltage tolerance is +/- 5%.
AMD 3-75 dryers are supplied with a standard VDE 16A - Shucko power cord and plug assembly (two
poles and a ground). AMD 105-168 dryers are supplied with a junction box.
Be sure to provide the proper fuses or breakers based on the data tag information located on the back of
the unit. The main power receptacle must be protected with a thermal overload/differential relay
(I∆n=0.03A), rated to the power consumption of the dryer (refer to data nameplate for nominal values). The
power supply cord must meet or exceed ratings for the total amp draw of the unit.

Connect to a properly grounded outlet. Improper connection of the equipment-grounding
conductor can result in risk of electric shock.

Do not use adapters on the plug receptacle - if it does not fit the outlet, have a proper outlet
installed by a qualified electrician.

2.8. CONDENSATE DRAIN

The condensate is discharge at the system pressure.
Drain line should be secured
Never point the condensate drain line towards anybody.

The dryer comes with a flexible plastic drain tube.
The condensate drain occurs through a solenoid valve protected with a mechanical strainer.
The condensate coming from the separator is previously filtered, then discharged.
The solenoid valve coil is operated by electronic instrument (dryer controller).
If an electronic drainer is installed, the intervention times are determined by the internal capacitive sensor
(see specific paragraph).
The drainers cannot be connected to pressurized systems.

Don’t dispose the condensate in the environment.
The condensate collected in the dryer contains oil particles released in the air by the compressor.
Dispose the condensate in compliance with the local rules.
We suggest to install a water-oil separator where to convey all the condensate drain coming from
compressors, dryers, tanks, filters, etc.

3. START UP

3.1. PRELIMINARY OPERATION

Verify that the operating parameters match with the nominal values reported on the data plate of the
dryer (voltage, frequency, air pressure, air temperature, ambient temperature, etc.).

Before delivery, each dryer is submitted to accurate tests simulating real operating conditions.
Nevertheless, the unit could be damaged during transportation. We therefore suggest to check the integrity
of the dryer upon arrival and to keep it under control during the first hours of operation.

The start-up must be performed by qualified personnel.
It’s mandatory that the engineer in charge adopt safety operational conditions complying with the
local safety and accident prevention requirements.
The same engineer will be responsible for the proper and safe operation of the dryer.
Never operate the dryer if the panels are not in place.

• Verify that the DewPoint temperature displayed on DMC15 electronic instrument is correct.

• Switch OFF the air compressor.

• After a few minutes, switch off the main switch on the control panel of the dryer (pos. 1).

NOTE : A DewPoint included in the green operating area of the electronic controller is correct
according to the possible working conditions (flow-rate, temperature of the incoming air, ambient
temperature, etc.)

During the operation, the refrigerating compressor will run continuously. The dryer must remain on during
the full usage period of the compressed air, even if the air compressor works intermittently.

The number of starts must be no more than 6 per hour. The dryer must stop running for at
least 5 minutes before being started up again.
The user is responsible for compliance with these rules. Frequent starts may cause
irreparable damage.
