Product overview
4.3.3 Electronic controller
The valve blocks above and below are controlled by the controller via solenoid valves. The controller
thus determines the pressure and the direction of the air flow in the drying agent cartridges.
4.3.4 Multi-way distributors
The multi-way distributor provides pneumatic connections on all sides of the device. The flow direction
is indicated by arrows. The standard model of the dryer is configured with the 3 inputs on the left and
the 3 outputs on the right viewed from the front of the device. Different arrangements of the openings
are available by repositioning the opening sockets
è
5.1 Ports for input and output.
4.3.5 Drying agent cartridge with integrated dust filter
The drying agent cartridges contain a drying agent for drying compressed air. The drying agent is in a
transparent pipe with end pieces permeable to air at both ends. In the top part of each cartridge is a
1-micron filter for separation of residual dust from the drying agent. The cartridge length varies with
the nominal power of the dryer.
4.3.6
Air reservoir
The drying agent cartridges are located in an air reservoir made of extruded aluminium. The air
reservoir is equipped with pressure-resistant end caps. Operating pressure and flow rate through the
cartridges are controlled by the valve blocks installed between the two air reservoirs. The regeneration
air flow (purge air flow) is controlled with the air gun nozzle on the upper valve block.
4.3.7
Alarm relay
An alarm relay with a connection for an alarm device is installed on the electronic controller. A visual or
audible remote alarm system can be connected at this connection.
The alarm relay switches in the event of a malfunction or if service is required. A red LED in the display
signals an error.
When the error is cleared, the alarm relay is reset, but only after the current switching cycle has ended
or the electronic controller has been reset.
4.3.8 Air gun nozzles
For proper and effective operation, a certain amount of purge air must be generated depending on the
operating pressure. The volume of purge air is adjusted to the operating pressure by selection of the
correct air gun nozzle.
As delivered, the adsorption dryer is configured with an air gun nozzle for an operating pressure of
0.7 … 0.9 MPa (7 … 9 bar, 101.5 … 130.5 psi).
If the device is to be operated at a different operating pressure, the air gun nozzle must first be
replaced with a suitable air gun nozzle from the air gun nozzle set
è
8.4 Replacing air gun nozzle.
The following table
è
Tab. 8 Required air gun nozzleshows the numbers of the required air gun
nozzles for the possible operating pressures.
