Moisture in compressed air is damaging. Without proper treatment, this vital energy source is a wet, gritty, acidic brew, silently destroying all that it comes in contact with. hold the key for systems requiring high quality, reliable air in an energy efficient package. By installing an Eastern Air HR Externally Heated or HB Blower Purge dryer Eliminate Water from Your Compressed Air System In today s competitive industrial markets, dry compressed air is a necessity not a luxury. The Eastern Air Products Genesis Series of Heat Reactivated compressed air dryers the user will see immediate results in the removal of moisture and contaminants from their system. While there are many different applications where heated desiccant dryers apply, no two applications are exactly alike. system operation after only a few minutes of interaction. Because the EAP heated dryer is provided with three independent exhaust Genesis Heated Dryers Upon installation, there are a number of variables within the operating environment where the dryer may be located. Through EAP s exclusive process of Tuned Regeneration, the user can dovetail the dryer regeneration process to achieve optimal results. Overall KW reduction and alleviation of dew point bumps can be realized through a process of tuning the interactive settings in the Logic Pro Master Controller. Understanding the Master Controller is so easy, most users are comfortable with system temperature readouts, the user can quickly see the heating pattern of the regeneration tower. Adjustments to heating temperature, duration and cycling controls can all be made without the need for costly programming. Slight adjustments from winter to summer months can result in maintaining system peak operational efficiency, while reducing energy usage. Adjustments of cooling cycles can reduce dew point spikes and maximize air volume available to process.
EAP Genesis heat reactivated desiccant dryers use the adsorption method to remove saturated compressed air flows through the drying tower, its moisture content adheres to the surface System Flow Schematics moisture from compressed air. Pressure dew points of minus 40 0 F/C to as low as -70 0 F (-56 0 C) are achieved by directing the flow of saturated compressed air over a bed of desiccant. As the of the desiccant, resulting in reduced relative humidity and optimal dew points. The dried process air is final polished by micron filter and sent to the plant air distribution system. In order to fully and effectively regenerate the off line saturated tower of the HR series, EAP utilizes the most advanced and highly tuned procedure in the industry. A regulated amount of already dried process air (approx. 7%) is heated by way of a low watt density heater and passed down (counter current) through the desiccant bed. This heated purge air, exhausted to atmosphere, removes all of the collected moisture adhered to the desiccant from the previous drying Air Out Air Out HR Regeneration Pre Exhaust Valve Main Exhaust Valve Inlet Valve HB Regeneration Air In Air In Pre Exhaust Valve Main Exhaust Valve Inlet Valve The EAP HB series of dryers also use heated air to regenerate the off line tower. However none of the process air is used during regeneration. A high efficient packaged blower assembly directs only heated atmospheric air counter current through the desiccant bed, removing all of the moisture that was collected during the previous drying cycle. Dew point spikes or heat bump can be avoided by tuning the regeneration cycle to meet the application. Energy (KW) requirements are greatly reduced through the use of our exhaust system temperature controllers. HR & HB Features Upon achievement of optimal temperatures in the regenerating tower, the heater system is turned off and the tower is cooled in preparation for its return to the drying process. Cooling and dry purge cycles can be customized to provide the best regeneration results. All EAP heated Dryers are equipped with fail-safe, and heat-safe directional valves. Should there be a power failure or emergency stop the inlet air directional system will maintain its exact position, locking out the regeneration tower. This protects the user from allowing excessive heated purge to enter the distribution system, which can affect process and damage downstream pneumatic devices. Upon restoration of power, the retentive memory systematically steps the dryer back into process condition without interaction from the user, and without affecting the duration of the current regeneration.
