DRYPOINTÂ® RA | Eco Series | Energy Saving Refrigerant Dryers
Refrigerant air dryers are commonly found in the majority of general industrial plant air applications. They offer users the best price-to-performance ratio in comparison to the compressed air quality produced. While the treated air may not be as dry as can be achieved with desiccant or membrane dryer technologies like DRYPOINTÂ® X and DRYPOINTÂ® M, the dry outlet air from refrigerant dryers is more than acceptable for the majority of applications.
Features & Benefits
How it works
Warm compressed air, saturated with water vapor, is precooled in the air/air heat exchanger (1) when entering the refrigeration dryer. Because demand on a compressed air system is often varied, the DRYPOINTÂ® RA VSD intelligent controller monitors the incoming conditions and adjusts the compressor and condenser fan speed (2a) to meet the required cooling capacity of the refrigerant in the downstream air/refrigerant heat exchanger (2b). This action thereby saves energy when low conditions are reached, and over the life of the dryer operating costs decrease. The gravitational force sustains a particularly high droplet separation of nearly 99%. In the very large condensate collection chamber with subsequent recirculation, the flow velocity is significantly reduced. Re-entrainment of already separated droplets is reliably prevented in this manner (3). The accumulated condensate is discharged from the DRYPOINTÂ® RA via the level controlled BEKOMATÂ® condensate drain avoiding any compressed air losses, and can be processed reliably using processing systems such as the QWIKPUREÂ® oil-water separation system or the BEKOSPLITÂ® emulsion-splitting plant (4). Prior to leaving the DRYPOINTÂ® RA, the dried and cold compressed air is reheated in the air/air heat exchanger. Through this process, the relative air humidity is significantly reduced and the cooling capacity employed is recovered by up to 60%.
