Compressed Air Dryer, Drypoint RA

BEKO Compressed Air Technologies Pvt Ltd offers Drypoint® RA, the most economic way to dry compressed air, an investment that pays off. 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 per cent of the total costs are allotted to the pure investment, while 70 to 80 per cent 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. In the Drypoint RA, compressed air drying takes place via an optimum heat exchange through a counter-flow process over the cooling surface; the air flows constantly in a downward movement without turbulence. This generously dimensioned counter-flow heat exchanger, which includes an air/air and an air/refrigerant heat exchanger, cools the compressed air down to a temperature of +3°C. The size of the heat exchanger not only supports a particularly effective cooling, but also reduces the flow resistance to an absolute minimum. Warm compressed air, saturated with water vapour, is pre-cooled in the air/air heat exchanger when entering the refrigeration dryer. The required cooling capacity of the refrigerant in the downstream air/refrigerant heat exchanger is reduced by this action and the system becomes more energy-efficient.
