11 DESCRIPTION What is the CDS? Typical applications (basic) Typical applications (advanced) Typical applications How it works (drying) How it works (conveying) UGS001/0798 Central Distribution System 2-1

12 WHAT IS THE CDS? CDS stands for Central Distribution System. A Typical system consists of 2-6 individual drying stations, a central dehumidifying unit, supply and return manifold, and conveying opportunities. The CDS system can run high volume long runs or low volume short runs. You can configure a system that will go from single or multi-source to single or multi-destination. The system provides isolation valves so that you can remove any station from the system to change materials, perform a cleanout or only use as many stations as you need. Modular components make the CDS system as automated or basic as you need. The advanced system eliminates moisture regain. The CDS system will save money by preventing the need for multiple dryers. This will cut the cost of your energy usage. TYPICAL APPLICATIONS Here are some things to remember when considering the possibilities: Each station can be different. One station may have a heat booster,drying Monitor, and single tube distribution box, and the next may have only a pocket conveying valve. It is possible to use color, as long as the color can withstand the temperature necessary to keep the rest of your material dry. Pocket Conveying requires some type of control (SLC deluxe for central system, Selectronic 4+ or 5 for individual stations) and works best with a direct feed loader (K loader) at the machine. A dry air generator may be necessary in a plant with high humidity. If you are thinking about the possibilities of expanding your CDS system in the future, plan up front. Larger systems may require larger dryers. Uninsulated manifolds are supplied when the dryer is supplying only regeneration capabilities. The CDS can handle a wide range of material types and Throughput types. Throughput can be up to 900 lb/hr (150 lb/hr per station), but will vary due to hopper size and material used. 2-2 DESCRIPTION Central Distribution System UGS001/0798

13 A central dryer is used to provide dehumidified air. The heat boosters provide the heat to the air entering the hoppers. The hoppers are hand fed and emptied into buckets. The system still has isolation valves and the bypass valve, allowing one or more of the stations to be turned off during a process. This application should only be used when the material being handled does not regain moisture easily. TYPICAL APPLICATIONS (BASIC) Shown below is the CDS system at the most featured state. This CDS system begins with the core system and adds a pump with dust collector for loading capabilities both on the throat, and on the hoppers in the CDS. TYPICAL APPLICATIONS (ADVANCED) This system uses a dry air generator for dry air conveying.,@ À,@ À,,@ À,@ À, Each hopper has a Drying Monitor which will monitor the exact conditions of the material in each hopper. The material is directed into a fantail manifold, where it can be sent to,@ À,@ À, many destinations from a single source. The pocket conveying valve allows for purging. UGS001/0798 Central Distribution System DESCRIPTION 2-3

14 HOW IT WORKS (DRYING) 1 2 One central dryer provides dehumidified air through a supply manifold to each hopper on the system. Just before the air enters the hoppers, it passes through the heat boosters. The heat boosters make sure that the temperature is at the set point entered by the user. 3 Once the heated, dehumidified air passes through the hopper, it exits to the return air manifold and returns to the dryer for processing again. The isolation valves are used to disconnect any station from the system for changing material or cleanout while the other stations remain in use. A bypass valve between the supply and return air manifolds acts as a pressure relief valve and allows excess air to pass from the supply manifold to the return manifold. The bypass valve makes it possible to disconnect a station from the system without effecting the other stations performance. Optional add-ons will provide further monitoring of material in the hopper, pocket conveying capabilities, dewpoint monitoring, open loop dehumidified conveying to the throat, and multiple source-multiple destination material handling. 2-4 DESCRIPTION Central Distribution System UGS001/0798

15 UGS001/0798 Central Distribution System DESCRIPTION 2-5 HOW IT WORKS (CONVEYING) yyyyy yyyyy yyyyy yyyyy yyyyy yyyyy yyyyy yyyyy Material is fed into the hopper either by hand or using a loader. Material stays in the hopper until it is dried. Once processed, the material passes through the hopper one of three ways: using the manual slide gate and emptying into a bin, using a single-tube distribution box, or using a pocket conveying valve (shown). A Peripheral Pump or other vacuum conveying equipment pulls the material from the pocket conveying valve to the throat of the machine

18 UNPACKING THE BOXES No matter what kind of a system you ordered, it is going to require some assembly. Always read this manual completely before assembling. Depending on what you ordered, you will have a number of different boxes and pieces. For each station, this is what you should have: (your station may not include a loader, and may have the optional remote heat booster control. Each system includes one bypass valve and 2 manifold adapters.) loader heat booster manifold to dryer adapters hose clamps bypass valve heat booster control/ enclosure hopper hose air pressure tap hose NOTE: Manifold hose pieces (number and size dependent on what size system, and how many stations) isolation valves RTD probe floor stand manifold T s 3-2 INSTALLATION Central Distribution System UGS001/0798

20 UNPACKING THE BOXES Accessories and Options: The Drying monitor will monitor the material s exact conditions inside the hopper and alert you of any problems. The Peripheral Pump is used to pull material from the hopper (using a pocket conveying valve or a single tube distribution box) to the throat of the machine. The Dust Collector prevents material and dirt from being pulled into the conveying system s vacuum pump The Dry Air Generator is used to provide dry air to closed loop systems and prevent moisture regain in conveying lines. The single tube distribution box is one option for emptying your hopper into a conveying line. The pocket conveying valve is another method of emptying material from the hopper to the conveying lines. It also allows for purging. A direct feed vacuum receiver mounted to the throat of a processing machineworks well with the CDS system and prevents large amounts of material from sitting on the throat of the machine. The fantail manifold is used to convey from one material sources to multiple destinations, or from multiple material sources to multiple destinations. 3-4 INSTALLATION Central Distribution System UGS001/0798

21 The CDS system is easy to install, if you prepare the area properly, and follow the installation procedure later in this manual. 1 Make sure the installation area provides: Grounded, disconnectable power sources supplying the correct current for each piece of equipment in your system. Check each piece of equipment s serial tag for the correct amps, voltage and cycles. Field wiring should be completed by qualified personnel to the planned location for the CDS system. All electrical wiring should comply with your region s electrical codes. PREPARING FOR INSTALLATION NOTE : You are responsible for providing any additional electrical disconnects that may be required. Enough room for the entire system to be together. This system is designed so that all equipment can be together in one location. Do not place pieces of equipment farther apart than intended. Material vacuum lines to the general area of the system. It is best to make sure you know where the material lines are going to be before you install your system. Common compressed air line with regulator. The Pocket Conveying valve uses a clean, non-lubricated source of air at psi. We recommend filters and regulators on all compressed air lines. Minimum clearance for safe operation and maintenance. The CDS system should be placed in a location where it has inches (76-91 cm) clearance on all sides. 2 3 Have a plan. Know where you are going to install each control box, all material lines, and all electrical lines. Sort and begin to lay out the pieces. Refer to the illustrations earlier in this section, and begin laying out the pieces for the manifold and each station. Remember to match all sizes. The size of the heat booster inlet should match the size of the hose, the isolation valves, and the T on the manifold. NOTE : Never bundle communication lines with high power electrical lines, or conveying piping. Static electricity, and electric current will affect communication lines. UGS001/0798 Central Distribution System INSTALLATION 3-5

22 INSTALLING THE SYSTEM NOTE : See the appropriate equipment manual for more information on proper installation. NOTE : If you are using a Drying Monitor, install the DM-1 probe before mounting the hopper WARNING: Do not stand on the equipment Do not use the floorstands or any equipment as a ladder or step. This equipment is not designed to safely support a person. Clean out the area for your CDS system. Lay out all the pieces to your system. Make sure that the T stub ends match the hopper outlet size. Set the floorstands and the dryer. We recommend that you bolt the floorstands to the floor. Mount the hoppers to the floorstands. Place the largest hopper closest to the dryer, and the smallest hopper farthest from the dryer. Mount the hopper drainport below the floorstand. On the flat bottom hopper, it may be necessary to drill a clearance hole in the floorstand Mount the pocket conveying valve or distribution box. They may be oriented in which ever way is easiest to connect to the conveying system. Mount the Heat Booster on the hopper. See the Heat Booster User Guide for instructions on installign the isolation valves, heater box, control and RTD sensor. Mount the mitered elbow and bypass valve on the last floorstand in the system. Veriy that the valve is 3-6 INSTALLATION Central Distribution System UGS001/0798

23 8 Install the manifold, manifold adapters, and piping to the heat booster. Install the manifold beginning with the end furthest from the dryer. Begin with the upper level of the manifold (return air). Complete this return air manifold to the last hopper and adaptors. Then beginning at the lower end of the bypass valve, install the manifold piping back the supply air line to the dryer. Make sure the placement of the manifold does not obstruct the outlet of the distribution box. INSTALLING THE SYSTEM NOTE : If you have insulated hose, place it from the dryer to the manifold on the supply side Continue the piping for any takeaway conveying. If the piping and the heat booster enclosures are going to be mounted on the same wall, make sure that there is enough room for the enclosure. If you are using an existing dryer for dehumidifying, disable the process heaters Plan where you are going to place each control. (heat booster enclosure and control, Drying Monitor, SLC or Selectronic controls) Connect the wiring from the heat booster to its electrical enclosure. Connect the heat booster control to its electrical enclosure. Connect the RTD probe to the heat booster control. Connect the wiring from the isolation valves to the heat booster electrical enclosure. Connect the air tubing from the pressure tap to the heat booster electrical enclosure. Connect all other controls by following the instructions in the appropriate manual. INSTALLING THE WIRING NOTE : Never bundle communication wires with electrical wires or conveying lines. NOTE : If you are using a pocket conveying valve and a Selectronic control, you will need to wire from the destination loader back to the conveying valve.
