General information Please complete the following information according to the type plate, vessel plate and contract documents. This enables the manufacturer to clearly identify the dryer and makes it easier to give advice if there are queries. It also simplifies the provision of spare parts and support.
Warranty notes For the conditions necessary for compliance with the warranty, please refer to our "General Terms of Sale and Delivery" The warranty shall be void if: The adsorption dryer is used for anything other than its intended use. ...
Signs and symbols used The following symbols are listed in this manual and/or are affixed to the construction: Symbol Meaning This symbol indicates tips for the efficient use of the adsorption dryer! Note This symbol indicates instructions for the safe handling of the adsorption dryer.
Intended purpose / use The adsorption dryer is designed for removing humidity from compressed air by adsorption in industrial compressed air systems. It requires the supply of saturated compressed air from a supply source. The main task is to reduce vaporous water components in the compressed air. Upstream filters and dryers ensure that only particles and drop shapes are separated.
Exceeding or even significantly undercutting the design data can lead to bad pressure dewpoints! The compressed air supplied to the adsorption dryer must be of the following quality: Free from aggressive and corrosive substances Free from particles and solids ...
Supply voltage 115 V, 50-60 Hz Protection class IP 54 Min. / Max. allowable pressure DDAP 6-55: 58 psi / 232 psi DDAP 65: 58 psi / 196 psi Sound pressure level up to 80 dB (A) (free-field measurement at 1.5 m) Min.
The type plate on the device shows important information. Please make sure that they are always legible and that they can be accessed. Danger zones Risk due to pressure-bearing parts Risk of slipping due to spilt desiccant on the floor ...
Desiccants The desiccants used do not fall into the hazardous substances group and are therefore not subject to labelling requirements. Nevertheless, please observe all common safety measures about using chemicals. Please also wear your personal protective equipment (goggles and respiratory protection). Please also note that the material accumulates contaminants, including oil vapor parts.

Operating principle: Monitoring the operation The following components are provided for regular monitoring: The pressure gauges display the operating pressure. They provide information about the regular switch-over of the adsorption dryer. The Ecomatic control display (shown on the right here), uses LEDs to inform you of the status or phase which the adsorption dryer is currently in.
Transport, storage and setup Transport Although great care is taken, please check immediately whether the adsorption dryer has been damaged in any way. Any kind of transportation damage must be pointed out immediately to the deliverer and manufacturer. Suitable hoisting equipment must be provided for the transportation, loading and unloading process.
Setup Please refer to the setup conditions described in Section 2.1. The basic data required for the setup can be found in the Performance data in Section 2.2. When setting up, make sure that the ground is level and capable of bearing the weight. ...
Choose a place of installation with the lowest possible compressed air temperature and with the highest level of saturated compressed air. This then increases the service life of the desiccant and the adsorption dryer works most efficiently. When installing an air cauldron, make sure that: ...
Commissioning All work on DDAP adsorption dryers and on the feeder and drainage systems must only be carried out by expertly trained persons and by those with experience in the field of compressed air! Additional note on commissioning: We recommend operating the dryer for 2 cycles without the silencers during the initial start-up, as a small amount of desiccant dust can develop during transport.
System operation Pressurisation has been successful. Check whether the compressed air system downstream of the adsorption dryer can be opened safely. Then proceed as follows: Slowly open the cut-off valves at the outlet of the adsorption dryer until you hear the flow noise. ...
Maintenance Maintenance work may only be carried out by suitably qualified personnel! Make sure that the device is free from pressure before starting work and observe the applicable accident prevention regulations for the place of installation! Regular maintenance work The following table gives an overview of the intervals and scope of the maintenance work: Maintenance of Activity...
Daily checks The following points should be checked every day: The difference in the operating pressure upstream and downstream of the adsorption dryer is not more than 7.3 psi. Open the manual drain slightly on the after-filter. It must not drip. ...
9.4.3 Two-year maintenance / Tighten the screws Due to the fact that DDAP dryers use the pressure swing process at least every 2 years the screws should be controlled. Please tighten the screws exclusively with a torque wrench. Check all screws on the top and bottom plate! DDAP 6-12 22.5 NM DDAP 20-35...
Replacing the desiccant Draining nozzle bottom Filling nozzle When replacing the desiccant, make sure to wear your personal protective equipment, namely the respiratory protection and goggles. Risk of slipping if material is spilt! The service life of the desiccant is heavily dependent on the quality of the compressed air at the inlet of the adsorption dryer.
materials in the correct order. WS and alumina materials generally form the water protective layer and must be added first. Once you've reached the filler plug, condense the material through slight vibration of the sheath of the adsorption dryer and then top up again until the desiccant no longer condenses, even with vibration.

Remove the screws on the side and exchange the piston. (ATTENTION! The piston with a nozzle needs to be on top) The socket on the back side of the piston block can stay closed. Replace the o-rings, too, and remount the block onto the plate.
ATTENTION! At assemble the block again please take care that the tightening torque of the screws is not higher than DDAP 6-12 max. 7 Nm; DDAP 20-35 max. 12 Nm; DDAP 40-65 max. 23 Nm Replacing the solenoid valves The solenoid valves are supplied fully assembled and should also be replaced as such.
Replacing the silencers The silencers lessen the noise generation of the regeneration process. In these silencers, proportionate desiccant abrasion in the form of dust is retained. Combined with the outgoing moist air, the silencers become clogged with dust over time and must be replaced.
9.10 Replacing the pressure dewpoint sensor If you've chosen the "ECOTROConomy" option, you must replace the sensor element every two years. Desiccant abrasion and oil vapours can cause the accuracy of the sensors to drift. This sensor element must therefore be replaced as follows: ...
