3.2 Electronic controller 2

The valve blocks (on top and below) are actuated by solenoid valves in the controller which determine the pressure and direction of the air flow in the desiccant cartridge.

3.3 Multiple distributor aJ

The standard design of the dryer is configured in such a way that the inlet openings are on the left and the outlet openings on the right when looking at the front of the device. By using the opening nozzles several different opening requirements become available. See also section 5.4.

Inlet

See the direction of the arrows for inlet side of the dryer

Outlet

Installation in corners

3.4 Desiccant cartridge with integrated dust filter 9

The desiccant cartridges contain a drying agent which has been developed for drying compressed air. The drying agent is contained in a transparent tube with end pieces which allow the air to flow through at both ends. In the upper part of each cartridge is a 1 micron filter to separate residual dust from the drying agent. The cartridge length varies with the rated output of the dryer.

3.5 Reservoir 7

The desiccant cartridge is located in an extruded aluminium reservoir and has pressurised end caps. The operating pressure and the flow through the individual cartridges is controlled by the valve blocks positioned between the two reservoirs. The regenerative air flow (purge air flow) is controlled by an external air nozzle with a small opening (front, central) on the upper valve block, accessible by removing the cover.


4. Function

During dry operation an even, uninterrupted supply of compressed air should be provided according to the specification.

This function is achieved with two compressed air reservoirs which operate in alternating cycles. If air is being dried in one reservoir, the drying agent in the second reservoir can regenerate.

In the adsorption dryer the main air flow is fed through the desiccant cartridge(s) of a reservoir. This removes the moisture so the required pressure dew point can be achieved. A small amount of the dry air (purge air) is fed to the other reservoir. The purge air flows through the desiccant cartridge(s), escapes into the atmosphere through a drain valve and thus regenerates the drying agent.

The regeneration cycle lasts 120 seconds. The corresponding drain valve is then closed. This means the regenerated reservoir can be brought up to system pressure with the purge air and can switch to the operating cycle. After a further 50 seconds the other reservoir starts a new regenerative operating cycle.


In order to protect the drying agent from contaminated pressurised air the micro filter MS6-LFM supplied must be mounted on the inlet of the dryer. On delivery, the three inlet options are on the left-hand side of the dryer (see arrow). If an inlet on the right-hand side is required the multiple distributor in the cover of the dryer must be turned (see chapter 5.4).

1. Select an inlet opening. Remove any sealing plugs and attach them to the unused inlet.

2. Insert a lightly greased O-ring 2 in the slot of inlet 1.

3. Fit the module connecting plate 3 with hollow bolt 4 with spanner size 10 (for PDAD-...y) or max. 14 Nm (for PDAD-...½). The maximum tightening torque is 15 Nm (for PDAD-...y) or max 18 Nm (for PDAD-...½). The module connecting plate 3 can be adjusted 90° for horizontal instal-lation of the dryer.

Number of the air nozzle

Allocating the air nozzles for various operating pressures

For correct and effective operation, there must be a certain amount of purge air, dependent on the operating pressure. By selecting the correct air nozzle, the amount of purge air is adjusted for the operating pressure. An incorrectly selected air nozzle can lead to premature failure of the dryer. The following table shows the allocation of the air nozzles for the various operating pressures. The grey area marks the permitted operating pressure range for the air nozzles included in the scope of delivery. If the operating pressure is outside the marked area, an air nozzle from the air nozzle set is required, see chapter 10
