HLA — Heatless Air Dryer
Principle of Operation:Dual-tower desiccant dryers for the continuous dynamic adsorption of water vapor from compressed air. Using pressure swing adsorption technology (PSA)*, air is being dried under pressure by passing through one desiccant bed while the other bed is being regenerated.
RegenerationRegeneration of the wet desiccant is accomplished without the use of heat. A small portion of the dried process air, called purge, is passed through the wet desiccant bed at near atmospheric pressure. This super dry air strips the desiccant of all water vapor previously adsorbed.
Fully assembled, packaged unit comes complete with desiccant

Regeneration purge flow is counter-current to the direction of air flow during drying
✓ Maximum removal of moisture and lowest dew point assured during the adsorption process

* How It Works: Pressure Swing AdsorptionPressure swing adsorption (PSA) is a widely used technology for air and gas purification. It is a regeneration process, accomplished by reducing the pressure. At moderate pressures such as 100 pounds per square inch, an adsorbent can support a certain amount of moisture. When that pressure is reduced to ambient air pressure, the adsorbent can only support a smaller amount of moisture. By alternating (swinging) the pressure from high to low between two adsorbent-filled vessels, you can adsorb large quantities of moisture at higher pressure in the online vessel, and then release that trapped moisture at lower pressure in the offline vessel, thoroughly drying the air.

HRA — Heat Regenerative Air Dryer
Principle of Operation: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. Dried air is used for both heating and cooling.
The process is called “Temperature Swing Adsorption” (TSA) because drying and regeneration rely upon swinging between two temperature-based adsorption equilibrium conditions, characterized by long cycles measured in hours.

VRA — Vacuum Regenerative Air Dryer
Principle of Operation:With vacuum heat regeneration technology, 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.
The compressor can be right-sized for lower compressor energy consumption
✓ Low energy costs
Two layered bed balances water resistance and high efficiency water retention
✓ Optimum dew point stability
Optimized silica gel-layered desiccant bed
✓ Highest surface/volume ratio provides maximum adsorption
Active heating under vacuum
✓ Low 208 ̊ F vaporization temperature
The moisture entering the desiccant bed during the regeneration and cooling phase never reaches the drying zone
✓ Changeover without dew point spike

Reductions in Greenhouse Gas (GHG) Emissions
Features & Benefits
www.xebecinc.com
Climate change has become a major issue for our planet. GHG emissions are responsible in large measure. 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 through produced as a result of commercial or responsible industrial activities.
By choosing energy-efficient dryer products, companies can considerably impact GHG emissions. In the United States, electricity companies produce an average of 1.36 lbs of GHG emissions per kWh produced. A 1500 SCFM Heatless Dryer will indirectly, through its energy consumption, be responsible for the production of 284 tons of CO2e per year.
The equivalent Vacuum Dryerwill indirectly generate 196 tons of CO2e per year, giving a net reduction of 88 tons. That’s significant!
Businesses that adopt energy-conscious practices today are building a more successful future for themselves, and a healthy, sustainable future for the world.
Xebec proudly stands behind its commitment of total customer satisfaction. Our aftermarket solutions (AMX™) include both parts and service:
• Fully certified technician on call
• Onsite commissioning
• Preventative maintenance
• Servicing and upgrading

STANDARD OPTION
VALVE BYPASSThe 3-valve and 9-valve bypass options provide a quick and safe way to take the dryer in or out of operation in a fraction of second without shutting down the entire air system.
LOW PRESSURE DEW POINT (LPD)Many industrial applications require extremely low pressure dew point. Xebec dryers with the LPD option are designed to provide consistent -100 ̊ F / -70 ̊C Pressure Dew point for these critical applications.
STAINLESS STEEL TUBINGStandard Xebec dryers use nylon tubing for the pilot air assembly. For clients using Stainless Steel as standard material for tubing systems, Xebec offers the option of replacing the nylon tubing by Stainless steel tubing.
In a fixed cycle dryer, one tower is always under regeneration, regardless of the load on the compressed air system. The Xebec AutoDew 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. When compressed air demand is low, the dryer uses correspondingly less energy.

CLASS 3000# FITTINGSThreaded Class 3000# fittings for connections ≤ 2" are used in all Xebec standard heated dryers (HRA, BPA and VRA series). For heatless dryers (HLA series), threaded Class 150# fittings are the standard for connections ≤ 2". Some industrial sectors have adopted stricter standards for pressure piping systems. For those kinds of applications, Xebec can incorporate threaded Class 3000# fittings in the HLA series dryer.
ROCKWELL (ALLEN BRADLEY) PLCMany industrial facilities use Rockwell (Allen Bradley) PLCs as a standard. For these clients, Xebec dryers can be equipped with that kind of PLC to facilitate connectivity and simplicity of the control system configuration.
