    CAUTION! • Never make structural changes to the adsorption dryer! • Only use original Sullair spares and accessory parts! • Never weld on a pressure vessel or change it in any way! • Carry out maintenance work only when the adsorption dryer is switched off, is depressurized and disconnected from the electric power supply.

  • Page 8: Product Information

    INSTALLATION, START-UP & MAINTENANCE MANUAL SD-220 TO SD-600 REV 04 – 10 Oct 2003 1.4. PRODUCT INFORMATION The adsorption dryer is used for the purpose of drying compressed air and other gases according to its respective design. As a "standard model" the adsorption dryer is equipped with two desiccant vessels, a pre filter and an after filter, and depending on certain conditions at the outlet, provides pure, dry and oil-free compressed air or gas.

  • Page 9: Technical Data Sheet

    * EDP (Enhanced Dew Point) Option indicates a dryer which has been specifically set up at the factory to obtain a –100 F pressure dewpoint. This option requires deration of the rated flow. Contact Sullair for details. Page 8 of 32...

  • Page 10: Transport

    In order to prevent droplets of condensate, oil, or dirt from getting into the desiccant, a Sullair MPH pre-filter must be installed up stream of the adsorption dryer. Without proper pre-filtration an oil film will build up on the desiccant reducing it’s drying capacity and degrading performance.

  • Page 11: Section 2: Installation

    ☛ Note Should you still have questions regarding installation, you can request additional installation recommendations from Sullair. CAUTION! Do not hydrotest the dryer! All vessel assemblies are factory pressure tested per design requirements prior to release from the manufacturer.

  • Page 12: Section 3: Start Up And Operation

    • All shut off valves on the pre-filter, adsorption dryer, after-filter and on the bypass line should be closed. • The ambient temperature must not be less than 33°F Breakdowns resulting from faulty installation do not fall under Sullair’s warranty obligation. ☛ Note The following sequence is to be heeded for the initial start-up: •...

  • Page 13: Description Of The Operation

    3.2.1. Description of the Operation • The standard Sullair SD dryer operates on a 10 minute NEMA cycle. In this configuration each desiccant chamber is drying for 5 minutes. This is known as a 5 minute half cycle. (EDP Dryers operate on a 4 minute NEMA cycle or 2 minute half cycle).

  • Page 14: Dryer Operating Sequence

    REV 04 – 10 Oct 2003 3.2.2. Dryer Operating Sequence The Sullair SD-220-DDS to SD-600-DDS heatless air dryers use a PLC as the standard controller. In the event of a power failure, the inlet valves remain in their position, and the exhaust valves will close and dryer will pressurize both chambers.

  • Page 15: Electrical Control

    You will find the operating and control voltage on the data sheet. The Sullair SD-220 to SD-600 adsorption dryers are normally operated with a PLC controller. The set times are adjusted at the factory during the test run.

  • Page 16: Section 4: Maintenance

    SECTION 4: MAINTENANCE ☛ Note - In order to ensure continuous and trouble-free operation, a maintenance contract with an authorized Sullair distributor is recommended. The following points should be checked regularly: Daily • Carry out a general visual check and watch out for possible disruptions during operation.

  • Page 17: Replacement Of The Desiccant

    INSTALLATION, START-UP & MAINTENANCE MANUAL SD-220 TO SD-600 REV 04 – 10 Oct 2003 Annually or after every 2500 hours of operation • Check the desiccant for impurities and change it if necessary. A brown or yellow color indicates that it has been contaminated with oil. Desiccant has an operating lifetime of about 8000 hours under normal conditions.
