The manual is organized into the following sections: Introduction Unpacking Using the Diffusion Dryer Maintaining the Diffusion Dryer Contacting TSI for Service Specifications vii viii Model 3062 Diffusion Dryer Model 3062 Diffusion Dryer Introduction The Model 3062 Diffusion Dryer is designed as a general-purpose aerosol dryer that has minimal aerosol loss. The aerosol inlet incorporates a water trap that collects coarse water droplets. Two concentric cylinders formed by an inner wire screen cylinder and an acrylic outer cylinder contain an annular volume of silica gel. As wet aerosol flows through the inner cylinder, water vapor diffuses through the wire screen and into the silica gel. Particle loss is minimized because the particles do not come into contact with the silica gel. The silica gel is easily regenerated in an oven at 120C. In addition, the silica gel may be replaced by other materials such as activated charcoal or sodium aluminosilicate.

Installation Two cradles with mounting screws and nuts are included with the dryer. They are used to mount the dryer horizontally in a convenient location. Two large rubber bands are provided to secure the dryer to the cradles. To fill the dryer with silica gel, see "Installing the Silica Gel" later in this manual. 2 Model 3062 Diffusion Dryer Using the Diffusion Dryer This section gives a description of the major components of the Diffusion Dryer. Inlet and Outlet Connectors The inlet and outlet connectors are in. female Swagelok fittings that connect to in. OD tubing. Water Trap and Drain Valve The inlet of the Diffusion Dryer contains a trap to collect large water droplets before they enter the desiccant. The trap is equipped with a drain valve to allow easy removal of trapped water. Desiccant Dryer The Model 3062 Diffusion Dryer is a general-purpose aerosol dryer consisting of two concentric cylinders (see Figure 2). The inner cylinder is made of wire screen and the outer cylinder is made of Plexiglas. The annular space between the two cylinders is filled with silica gel. The aerosol enters the dryer at the end equipped with the water trap and exits at the opposite end. The silica gel in the annular space maintains a dry atmosphere within the inner tube. Passing the aerosol through this tube dries the aerosol particles without substantial particle loss. Swagelok is a trademark of Crawford Fitting Co.

The section includes procedures on draining the water trap, removing, installing and drying the silica gel. Water Trap and Drain Valve The water trap provides a place for large water droplets to collect extending the life of the desiccant. This trap should be periodically drained as it collects water. To drain, rotate the valve clockwise until the water has been removed. Retighten the valve until snug. Drying the Silica Gel The silica gel contains indicator crystals that are blue when dry and become pink when wet. To dry the gel, remove it from the system (see next section) and bake it in a pan in an oven at 250F [120C] until the blue color returns. If the blue color does not return, the silica gel is no longer usable and must be replaced. 4 Model 3062 Diffusion Dryer The operational time per regeneration of silica gel depends on the aerosol flowrate through the diffusion dryer. The silica gel near the inner tube absorbs the moisture first. Hence, occasional shaking to replace the silica gel crystals near the inner tube with other crystals improves the drying power of the diffusion dryer. The following data represents the drying capacity of the dryer. It was tested in conjunction with TSI's Model 3076 Constant Output Atomizer, which has an aerosol flowrate of 3.5 liters per minute. Table 2 Drying Capacity of the Dryer How Used No diffusion dryer With one Model 3062 With two Model 3062s (in series) With one Model 3062 but after one hour of operation After shaking the Model 3062 to rearrange the silica gel crystals Measured Relative Humidity at Exit (%) 60 20 8 28 20 Removing the Silica Gel To remove the silica gel, do the following: 1. Disconnect the inlet and outlet connections and remove the dryer from its brackets (refer to Figure 1). 2. Holding the dryer vertically with the water trap at the top, remove the end cap on the inlet side. Important ! Do not attempt to unscrew the opposite end. It is glued in place and attached to the inner screen. Forcing the outlet end cap will damage the inner screen. 3. Turn the dryer upside-down and the desiccant will flow out into a tray or other container. Model 3062 Diffusion Dryer 5 4. Dry the silica gel as outlined in the previous section or replace it with new desiccant (if it becomes contaminated or will not regenerate). Installing the Silica Gel To install the silica gel, follow these steps: 1. Holding the dryer vertically with the water trap at the top, remove the end cap on the inlet side (if you have not already done so). Important ! Do not attempt to unscrew the opposite end. It is glued in place and attached to the inner screen. Forcing the outlet and end cap will damage the inner screen. 2. Hold the desiccant dryer with the open inlet end pointed up. 3. Install the filling jig on the inlet making sure that the mesh tube is covered by the center of the jig (see Figure 3). 4. Pour desiccant into the jig until the dryer body is almost full (leave about in., 6 mm unfilled). You may want to tap the body of the dryer to compact the desiccant. 5. Make sure the gasket in the end cap is undamaged and slightly greased. 6. Replace the removable end cap being careful to insert the solid tube on the end cap into the screen tube. 7. Make sure that the end cap is completely threaded in place. 8. Replace the dryer into its holding cradles and reattach the fittings to the inlet and outlet. 6 Model 3062 Diffusion Dryer Filling Jig Diffusion Dryer Body Figure 3 Installing the Filling Jig on the Inlet Model 3062 Diffusion Dryer 7 Contacting TSI for Service This section gives instructions for contacting TSI for technical information or for returning the Model 3062 Diffusion Dryer for service.
