SECTION 1 INTRODUCTION 1.0 Desiccant Dryer General Description The NDB/MPC/CDM Series dual-bed dryers are continuous-duty; desiccant dryers designed to supply an uninterrupted flow of constant, low dew point air. These units are completely automatic and require little maintenance to offer many years of trouble free service. 1.1 Principle of Operation 1.11 Adsorption Cycle The reduction of moisture is accomplished by the use of an adsorbent material called Molecular Sieves. The process blower draws humid air across the filter (and if supplied, through a precooler) and passes it thorough the adsorbing desiccant tower. The desiccant material adsorbs water vapor from the flow, leaving the air extremely dry, (-40 deg. F dew point or below). The dry air is then directed over the Process Heater, where the air is heated to a desired preset and it is then ducted to the drying hopper. The dry air enters, and is forced through, the hopper. The warm, low dew point air fills the hopper, placing all of the entering material in a moisture free environment. This causes the moisture in the plastic material to migrate to the surface where it is picked up by the dry air. This humid air is taken back to the dehumidifier where the moisture is adsorbed by the desiccant. Before the desiccant reaches the saturation point, the 4-way valve automatically reverses and transfers the humid airflow to the opposite tower. 1.12 Regeneration While one tower is on adsorption, the opposite tower is on regeneration. The blower forces air through the regeneration heater and desiccant tower. The desiccant is heated to the temperature required to desorb the water adsorbed by the desiccant during the proceeding drying period. Water vapor carried from the tower by the air is discharged to the ambient through the regeneration outlet port. The heater is de-energized when the desiccant is dry, and the tower is cooled to the required adsorption temperature. Adsorption and regeneration alternate automatically between the two towers in a continuous cycle. 1.13 Pre-cooler OPTIONAL Pre-cooling the drying air returning from the hopper lowers the inlet temperature to below 150 deg. F., maintaining high desiccant efficiency. Pre-coolers also condense out unwanted contaminants, including plasticizer, which can be harmful to the desiccant. If plasticizer is being condensed, a drain trap will be supplied to collect the condensate from the pre-cooling coil housing. On initial startup this drain-trap should be filled with water to prevent ambient air from leaking into the system and also to allow the condensate to drain from the pre-cooling coil housing to the drain trap.

SECTION 2 2.0 Unpacking INSTALLATION Caution should be exercised to see that the equipment is not damaged during handling. The crate must be removed carefully. The machine must not be used to pry against when removing the crate. The dryer is usually shipped completely assembled and requires no further assembly prior to installation. Do not tilt the desiccant section at angle single at an angle greater than 30 degrees during unpacking or installation because the desiccant may get into the valve assembly. 2.1 General Description When the unit is unpacked, make a visual inspection looking for missing parts or damage which may have occurred during shipment. Some parts, such as thermometers, hoses, and hose clamps are packed inside the hopper. All electrical and mechanical connections should be checked for tightness because vibration during transit may cause them to loosen. 2.2 Installing the Hopper The inside of the hopper and the perforated spreader cone or diffuser tube should be thoroughly cleaned to remove all dust and oil that may have accumulated during shipment to your plant. 2.21 Machine Mounted If the drying hopper is to be mounted directly to the process machine, it should be mounted in a vertical position. Secure the hopper with bolts through the bottom flange. Use braces or guy wires as necessary to assure a safe installation. 2.22 Floor Mounted Locate the hopper stand and install where desired. Bolt the stand to the floor. The hopper should be bolted to the stand in a vertical position, secure as required. 2.3 Diffuser Cone or Diffuser Tube Installation After the hopper has been installed and secured, the perforated diffuser cone or diffuser tube should be installed in the hopper. The cone rests on a flange inside the hopper near the bottom of the straight side (just below the clean out door if applicable) where it joins the outer hopper cone. This cone maybe installed either thorough the clean out door (if supplied) or by removing the hopper lid. Be certain the diffuser cone is seated firmly to the flange inside the hopper. The diffuser tube is installed by pressing it into the hopper inlet tube from inside the hopper. Either a perforated diffuser cone or diffuser tube (not both) is supplied depending on the size and design of the hopper. NOVATEC, Inc. 2016 All Rights Reserved 6

2.4 Connecting the Hoses The "Dry Air Outlet" duct should be connected to the bottom duct of the drying hopper, or to the inlet of the heater in a hopper mounted heater configuration. The "Humid Air Outlet" duct on the lid of the hopper should be connected to the return air inlet of the dryer. Dryers from NOVATEC are shipped with flexible hose and clamps for this purpose. The lengths of the hose should be as short as possible cut away any excess. It is vital that the system is airtight. We recommended the use of insulation on process airlines that are heated. Hose insulation is available from NOVATEC. 2.5 Regeneration Outlet Do Not Insulate the return air hose! The regeneration outlet duct discharges hot, humid air. In some cases ducting the air may be desirable. Extreme caution must be given to the length of duct so, as to not cause back- pressure to the regeneration blower. Contact the factory if the duct length will exceed four feet. If ducting outside, the reactivation air duct should be slanted down to prevent rain and moisture from entering the dryer. A trap for condensation should be located at the lowest point. 2.6 Utility Connections Field Wiring The specific electrical wiring schematics supplied with the CD/CDM and HB/HBM equipment should be reviewed and completely understood before initiating installation. If there is any ambiguous or conflicting information, contact the NOVATEC Technical Service Department before attempting to install the equipment. Dryer/HB Interlock Wiring Each HB has an interlock relay installed in its control box. The coil of this relay is connected in parallel to the dryer process motor starter coil. Should the dryer process blower shut off (i.e.; bed changeover, process blower motor overload), the HB interlock relay will power down the HB blower and heater. Typically the coil wires are labeled A and B on the terminal strip of the HB and dryer. Failure to interlock the HB relay with the dryer will not allow operation of the HB unit. Multiple HB s can have the A and B wires daisy chained from one unit to the next. Usually the interlock voltage is 115Vac. NOVATEC, Inc. 2016 All Rights Reserved 7

2.61 Power Connect the proper power supply through a main line disconnect switch (field supplied). Connect the green wire to earth ground. Because the Controller and various sensors are sensitive to 'Industrial Noise' the system must be properly connected to 'true' earth ground. The correct power supply requirements can be found on the specification sheet. Appendix A, or on the nameplate attached to the dryer. Local or national electrical codes should be followed as required. This is the only power connection necessary as the system is completely pre-wired and supplied with a control transformer to supply the necessary 115-vac control voltage. 2.62 Water If the unit is equipped with a pre-cooler, the proper water supply (see specification sheet, Appendix A) should be connected to the pipes marked "inlet" and "outlet" on the side of the precooler. If the pre-cooler is used to remove plasticizer or other condensates, the condensate drain (called the drain-trap) should be connected to suitable drainage. On initial start-up, this drain-trap should be filled with water to prevent ambient air from leaking into the system and also to allow the condensate to drain from the precooling coil housing to the drain trap. The drain trap must be full at all times. NOVATEC, Inc. 2016 All Rights Reserved 8

SECTION 3 OPERATION 3.0 Initial Start Up After the drying system has been fully installed and power connected, check that the master off/on switch is on. Verify that the TP177M Touch Panel is on. Press NOVATEC logo screen to continue. The TP177M will change to the Main Menu Screen. Press the Operation pad and the TP177M will change to the system display screen. Press the Start Pad. The dryer should now be running. Adjust the process temperature by pressing the 3D Process Setpoint pad. A full keypad will appear. Enter desired setpoint temperature and press. No further adjustments are required to run the dryer. However, if you wish, you may step through all of the parameters to verify or change any values entered at the factory. See SECTION 5 for a complete description of programming the TP177M/S7-224 controller. 3.1 Drying the Desiccant When first put on-line, or when it is deemed necessary, the desiccant should be thoroughly dried. To do this, reduce the process air setpoint to a level below ambient temperature so that the heater does not come on. Check the blower for proper rotation by observing the rotation of the motor at the end facing the control box. The proper rotation is indicated with an arrow on the blower housing. Allow the unit to dry-cycle for 24 hours. This will allow the moisture adsorbed by the desiccant during transit or inactivity to be discharged. Failure to dry cycle the unit may cause drying problems with the material. The dryer will achieve its lowest dew point after the 24- hour period. However, if your process is such that it does not require as low a dew point as possible, material may be dried after a minimum of four hours of dry cycling. Don't forget to raise the process setpoint to the temperature recommended for drying your material. The material must be at its drying temperature for its residence time period (usually 2 to 4 hours) before the material is dry enough to process. 3.2 Operating Procedure After the initial residence period is complete, the material is dry and ready for processing. As dry material is withdrawn from the bottom, wet material should be added to the hopper at the same rate. (NOTE: It is extremely important to keep the hopper as full as possible for proper drying). If any special options were ordered with your dryer refer to APPENDIX B for details and start-up procedures. NOVATEC, Inc. 2016 All Rights Reserved 9

SECTION 4 SENSORS 4.0 High Temperature Mechanical Limit Switch The NDB/MPC process heater is fitted with a mechanical temperature limit switch as a standard feature. It is a cartridge type thermostat with a range of -100 to 600 F. This switch is preset at the factory and under normal conditions it should never trip. In the event that a malfunction occurs and the temperature exceeds the preset limit this mechanical switch will open, shutting down the system and preventing any damage to the process or the equipment. The switch may be field adjusted if necessary. To change the temperature setting, remove the cover from the switch housing and turn the adjustment screw. A clockwise rotation lowers the setpoint and a counterclockwise rotation increases the setpoint. Each full revolution of the setpoint adjustment screw changes the temperature setpoint approximately 90. If the dryer is shutdown while the process temperature is elevated, an over temperature alarm may occur due to the increase in temperature without proper airflow. You should wait several minutes for the temperature to drop below the limit level before starting the dryer. You may also jumper the high temperature limit switch temporarily to cool the heater. 4.1 Hygro Dew Point Sensor The HYGRO Dew point Sensor is the standard sensor for NDB/MPC/CDM applications. The Sensor may also be called a White or Model M Sensor. It has a sensing range of -40 to +15 F. The electronics for this sensor are incorporated in the Hygro board assembly. The calibration has been done at the factory and no field calibration should be necessary. The HYGRO Sensor is a lithium chloride type. The sensor is installed in its sensing chamber when the dryer is shipped from NOVATEC. Even though the sensor does not read below -40 F, the dryer is still capable of lower dew points. If it is desired to know the actual dew point below 40 F the optional SHAW dew point sensor should be used. NOVATEC, Inc. 2016 All Rights Reserved 10

4.2 Shaw Dew Point Sensor The SHAW Dew point Sensor is an option for the NDB/MPC/CDM series dryer. It has a sensing range of -112 F to +32 F. An additional circuit board is required for its operation. The sensor is calibrated at the factory-it can be field calibrated if necessary. To calibrate expose the sensor to ambient air for several minutes by removing it from its sensing chamber. It may be necessary to hold the sensor in the closed palm of your hand on extremely dry days (less than +32 F dew point). The moisture from the ambient air or your hand will allow you to adjust the sensor. With the coaxial cable attached, adjust the "pot" on the dew point sensor board marked "sensitivity" or "cal". Adjust until the dew point displayed is +31 F. Re-install the sensor into its holder. Calibration is complete. The SHAW Sensor is a capacitance type (metal core coated with a hygroscopic dielectric and covered with a porous gold film) that measure moisture independently of temperature. The Shaw sensor is shipped in a separate container that has been placed inside the control box. The sensor should be removed from its container and screwed into its sensing chamber. Inside the control box is a coaxial cable with plug that should be connected to the SHAW Sensor. NOVATEC, Inc. 2016 All Rights Reserved 11

SECTION 9 MAINTENANCE AND INSPECTION SCHEDULE It is recommended that maintenance and inspection is done on a scheduled basis. Maintenance requirements will naturally vary widely for each installation and specific operating conditions. It is suggested that a complete inspection be performed with necessary maintenance at the end of the first, the first three months, and the first six months. These inspections will be indicative of how often future maintenance will be necessary. REMOVE POWER BEFORE SERVICING THE UNIT EVERY MONTH A. Inspect air filters. Clean or replace as required. Replace if cartridge is broken. The time interval for inspection should be shortened if experience indicates unusual dust loading. B. Check system for air leaks or flow obstructions and correct as required. EVERY 3 MONTHS A. Units equipped with sleeve bearing motors should be lubricated with SAE 20 oil. B Units equipped with ball bearing motors are factory greased and should be re-lubricated with high-grade ball bearing grease. NOTE: Most units are shipped with permanently lubricated bearings and no lubrication is required. All motors should be examined on an individual basis. C. Check heater amperage (See Specification Sheet) D. Check motor amperage (See Specification Sheet). E. Check all electrical connections to make sure that they have not become loose, especially those connections at contactors, motor starters, and heater elements. ONCE EVERY YEAR Check dehumidifier valve linkage and operation of valves. Check valve wiper seals for wear and tear. EVERY 2 YEARS or as NEEDED Remove top covers of dryer towers and replace desiccant. Inspect the high temperature silicon gasket and renew if necessary. (See Specification Sheet for the amount of desiccant). Warning: Tower lids and heater boxes may be extremely hot use caution when working with these parts. NOVATEC, Inc. 2016 All Rights Reserved 37
