SIGNIFICANT REDUCTION OF OPERATING COSTS
The energy costs, compared with the required investment, represent by far the biggest share of the total costs. But this cost factor also has the greatest saving potential! The DRYPOINT® RA refrigeration dryer slashes the energy costs and, as an all-round cost cutter, reduces the maintenance expenditure at the same time. Quite clearly a worthwhile investment.
Moisture represents the greatest threat to all the components it comes into contact with. The trouble starts with the formation of bacteria at a relative compressed-air humidity of around 70 %. As from a relative humidity of 40 %, the corresponding corrosion curve will rise steeply.
A quick and economic solution to the moisture problem is offered by the DRYPOINT® RA compressed-air refrigeration dryer. With most applications, the compressed service air merely requires cooling and drying in the range of normal values: cooling close to 0 °C and thus almost 100 % condensing of the water vapour contained in the compressed air. DRYPOINT® RA ensures the effective separation of compressed air and water vapour. T he resulting condensate is then reliably discharged using a BEKOMAT® condensate drain.
1 Warm, moisture-saturated compressed air is cooled down to a temperature of +37°F. The generous dimensions of the heat exchanger promote especially effective cooling, while flow resistance is reduced to an absolute minimum.
2 Contrary to conventional systems the air follows a downward path through the heat exchanger. Gravity action results in particularly high droplet separation of almost 99%. Within the very large condensate collection space, the flow velocity is greatly reduced, so that carry-over of droplets that have already been separated is reliably prevented.
3 The dried, cold compressed air is reheated in an air-to-air heat exchanger before discharge from the dryer. During this process, the relative humidity of the air is lowered considerably and up to 60 % of the cooling energy is recovered.
4 The produced condensate is discharged from the DRYPOINT® RA unit through the level-controlled BEKOMAT® condensate drain in a way that avoids pressure loss. The condensate can then be safely treated with appropriate treatment systems, such as the ÖWAMAT® oil/water separation system or the BEKOSPLIT® emulsion splitting plant.
The BEKO Dryer Range
BEKO's Product portfolio, a complete range of compressed air drying solutions for every application. By supplying application specific solutions BEKO ensures customers receive personalized attention to their compressed air drying needs. The result is a system that will provide the most reliable, energy efficient solution possible.
1 Warm, moisture saturated compressed air is cooled down to +37 °F. The generously dimensioned heat exchanger enables particularly effective cooling, while the flow resistance is reduced to an absolute minimum.
2 Contrary to conventional systems, the movement of air through the heat exchanger follows a downward pattern. The effects of gravity produce an exceptionally high droplet separartion efficiency. In the large condensate collection space, the flow velocity is greatly reduced. Re-entraining of previously separated droplets is thus reliably prevented.
3 Before leaving the dryer unit, the dried, cold compressed air is reheated in an air-to-air heat exchanger. During this process, the relative humidity of the air is lowered considerably and the same time up to 60% of the cooling energy is recovered.
4 The separated condensate is discharged, without wastage of compressed air, from the DRYPOINT® RA refrigeration dryer into the level-controlled BEKOMAT® condensate drain. It can then be treated according to requirements, for example, in an QWIK-PURE® or ÖWAMAT® oil/water separation system or a BEKOSPLIT® emulsion splitting plant.
