  • Page 4: Safety And Precautions

    TWP/TWB201 – TWP/TWB7501 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.

  • Page 5: Installation

    TWP/TWB201 – TWP/TWB7501 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).

  • Page 7 TWP/TWB201 – TWP/TWB7501 Each elbow installed in the exhaust piping is equivalent to 10 feet of pipe. If the exhaust piping is vertical, a drip line must be installed to remove moisture. It is recommended to pipe the exhausts separately for ease of maintenance and troubleshooting.

  • Page 8: General Operation

    TWP/TWB201 – TWP/TWB7501 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 26: Start Up

    TWP/TWB201 – TWP/TWB7501 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 27: Timing Configuration

    TWP/TWB201 – TWP/TWB7501 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).
