the dryer is not blowing down

The Parker Airtek TWP200 dryer may not be blowing down because it is in the "DRYER PARKED" state, meaning it has not yet been started. Once started, it cannot be placed into the PARKED state without reprogramming the PLC. Additionally, if the regenerating tower is waiting to depressurize before purging, it may not be blowing down yet.

  • Page 4: Safety And Precautions

    TWP/TWB200 – TWP/TWB9000 SAFETY AND PRECAUTIONS Use EXTREME CAUTION when working in the vicinity of the dryer. Adhere to all warning labels on dryer. Relieve pressure before servicing dryer or associated equipment. Disconnect power before servicing dryer. Always wear eye protection when in the vicinity of the dryer. Ear protection is recommended, especially if the dryer is being operated without mufflers.

    TWP/TWB200 – TWP/TWB9000 INSTALLATION Inspect the dryer upon receipt for any damage that may have occurred during shipment. Each desiccant dryer is supplied with a User Manual, dryer general arrangement drawing, and ASME pressure vessel U1A data reports (where applicable). The initial charge of desiccant is included with the dryer.

  • Page 8: General Operation

    TWP/TWB200 – TWP/TWB9000 GENERAL OPERATION The externally heated and blower purge desiccant dryers are designed to remove moisture in water vapor form, from compressed air to yield dewpoints of -40°F or better. The twin tower design allows constant drying of compressed air through one adsorption vessel while the other vessel desiccant bed regenerates by using heated dry purge air.

  • Page 22: Start Up

    TWP/TWB200 – TWP/TWB9000 START UP Verify all piping and electrical connections are secure. Do not power the dryer at this time. Start the compressor and pressurize the air system, bypassing the dryer. Slowly pressurize the dryer by opening the inlet isolation valve. It is important to allow the dryer to slowly pressurize to prevent fluidization of the desiccant bed.

  • Page 23: Timing Configuration

    TWP/TWB200 – TWP/TWB9000 It is not uncommon for the heater to shut down due to an over-temperature condition during initial startup of the dryer. If this should happen, verify that the purge pressure setting agrees with the suggested setting and that there is no backpressure in the regenerating tower (as would occur if a muffler was clogged or a check valve was not functioning properly).
