5 hla Heatless Air ryer SATURATE COMPRESSE AIR 7 bar 0 bar At normal operating pressure in the online tower, water vapor adheres to the molecular sieve desiccant so that only dry air leaves the outlet. The pressure is then reduced in the offline tower which releases the adsorbed water vapor. ried air is used to purge the water vapor from the desiccant before the next cycle. ONLINE ET EXHAUST AIR OFFLINE The term Pressure Swing Adsorption (PSA) illustrates how drying and regeneration rely upon swinging between two pressure-based adsorption equilibrium conditions, characterised by short cycles measured in minutes.

7 hra Heat Reactivated Air ryer SATURATE COMPRESSE AIR 7 bar 0 bar At normal operating temperature in the online tower, water vapor adheres to the desiccant so that only dry air leaves the outlet. An electric heater then raises the desiccant temperature in the offline tower which releases the adsorbed water vapor. The desiccant must be cooled before switching back online. ried air is used for both heating and cooling. ONLINE ET EXHAUST AIR RY REGENERATION AIR OFFLINE The process is called Temperature Swing Adsorption (TSA) because drying and regeneration rely upon swinging between two temperature-based adsorption equilibrium conditions, characterised by long cycles measured in hours. HEATER -40ºC PP CLEAN RY AIR Autoew Energy Savings Option Available for all Models In a fixed cycle dryer, one tower is always under regeneration, regardless of the load on the compressed air system. The Xebec Autoew option reduces energy usage by delaying the start of the regeneration cycle until the online tower is fully saturated. The dew point at the dryer outlet is monitored with a precision hygrometer which senses when the online tower can no longer maintain dew point. hen compressed air demand is low, the dryer uses correspondingly less energy.

9 BPa Blower Purge Air ryer SATURATE COMPRESSE AIR 7 bar 0 bar At normal operating temperature in the online tower, water vapor adheres to the desiccant so that only dry air leaves the outlet. A blower pushes fresh air through an electric heater to raise the temperature in the offline tower and release the adsorbed water vapor. ried air is used for cooling the desiccant before switching back online. ONLINE ET EXHAUST AIR HEATER BLOER RY COOLING AIR OFFLINE In all of Xebec s heated TSA dryers, the towers are filled with two layers of desiccant. The first layer is selected for its ability to efficiently remove bulk water from the wet compressed air and to guard the second layer, which is sensitive to wet air. This second layer is most effective at the dry end of the spectrum, removing the residual water vapour down to very low concentrations to produce the clean dry air required. -40ºC PP CLEAN RY AIR Xebec Filtration Prefilter: Features: Afterfilter: Features: Coalescing prefilter removes mist and aerosols ifferential pressure indicator Manual, float, or electronic drains Particulate afterfilter removes dust ifferential pressure indicator and manual drains Filter and dryer bypass options: 3-valve: bypasses dryer and filters for servicing 7-valve: bypasses dryer and/or filters for servicing 9-valve: dual filters for online servicing and dryer bypass Filters can be shipped loose for site-specific installation 9

11 VRa Vacuum Regenerated Air ryer 7 bar SATURATE COMPRESSE AIR mm H20 At normal operating temperature in the online tower, water vapor adheres to the silica gel desiccant so that only dry air leaves the outlet. A blower draws fresh air through an electric heater to raise the temperature in the offline tower and releases the adsorbed water vapor. ONLINE FRESH AIR HEATER BLOER ET EXHAUST AIR RY REPRESS AIR -40ºC PP OFFLINE CLEAN RY AIR In conventional blower purge dryers, ambient air is not used to cool the desiccant bed because too much moisture is re-adsorbed from the air. This pre-loads the bed and affects dew point performance in the next cycle. esiccants adsorb a lot of moisture at high pressure and none under deep vacuum. This is the basis of pressure swing adsorption used in heatless designs. The Vacuum Regenerated technology exploits this phenomenon: ambient air is drawn through the bed, creating a partial vacuum inside the tower. The pressure difference appears small compared to a conventional blower purge dryer, but it is enough that the desiccant adsorbs very little moisture during cooling. The VRA dryer design has zero purge loss because it does not use any compressor capacity for regeneration heating or cooling. Reductions in Greenhouse Gas Emissions Climate change has become a major issue for mankind. Greenhouse gas (GHG) emissions are responsible for this change. For industry, the carbon footprint measured as tons of carbon dioxide equivalent (CO2e) is the term used to quantify and represent the total amount of GHG produced as a result of commercial or industrial activities. By choosing energy efficient dryer products, companies can considerably impact GHG emissions. In the United States, electricity companies produce on average 1.36 lbs of GHG emissions per kh produced. A 2000 SCFM Heatless ryer will indirectly, through its energy consumption, be responsible for the production of 390 tons of CO2e per year. The equivalent Vacuum ryer will indirectly generate 207 tons of CO2e per year. A net GHG reduction of 183 tons per year. Businesses that adopt energy-conscious practices today are building a more successful future for themselves, and a healthier future for the world. 11
