Beko DRYPOINT® RA Refrigerated Dryers
Nuvair proudly uses Beko refrigerated dryers in all our low pressure compressor packages. Beko compressed air refrigeration dryers provide users with several advanced features creating a balanced and efficient drying system. The dryers come in a wide array of SCFM configurations with convenient 50/60 Hz capabilities. For models not available for purchase online, please contact the Nuvair sales team for product availability and estimated lead times.
The air-cooled DRYPOINT® RA compressed air refrigeration dryer model range allows optimum adaptation of the compressed air processing to individual operating conditions. All models excel in minimum pressure loss even with varying workloads and in their low energy consumption.
Refrigerant air dryers 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, the dry outlet air from refrigerant dryers is more than acceptable for the majority of applications.
It is not the investment costs that determine the cost efficiency calculation regarding refrigeration dryers—but the operating costs. Considering an operating period of five years, only between 20 and 30 percent of the total costs are allotted to the pure investment, while 70 to 80 percent are allotted to the ongoing operating costs.
These costs are split equally between electricity costs, flow resistances in the system and compressed air losses through leaks. Pressure drop at critical spots must be compensated by enhanced compressor performance and the resulting additional energy demand.
With DRYPOINT® RA, these operating costs can be reduced by almost half, considering a period of time of five years. In the return-on-investment calculation, the full potential of the new refrigeration-dryer generation is proven: the dryers pay off within an operation time of only six months.

*How It Works
Warm compressed air, saturated with water vapor, is precooled in the air/air heat exchanger (1) when entering the refrigeration dryer. The required cooling capacity of the refrigerant in the downstream air/refrigerant heat exchanger (2) is reduced by this action and the system becomes more energy-efficient. 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 DRYPOINT® RA via the level-controlled BEKOMAT® condensate drain avoiding any compressed air losses, and can be processed reliably using processing systems such as the QWIK-PURE® oil-water separation system or the BEKOSPLIT® emulsion-splitting plant (4). Prior to leaving the DRYPOINT®, 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%.
