BOGE FRDA tandem dryers

Compressed air dryers are essential for avoiding interruptions to operations or even production downtime due to water in the compressed air system and in the final application.

With the FRDA tandem dryer, BOGE includes a combined refrigeration and adsorption dryer in its product range for the first time. FRDA is a suitable solution when consistent but variable pressure dew points between -70 and +3°C are required. The combination of the two drying processes enables a high level of energy efficiency and flexibility.

It is simple to switch between the pressure dew points of a refrigeration dryer and those of an adsorption dryer, without hardware adjustments being required, by means of the tandem dryer control. The result is that a residual moisture of up to 0.003 g/m³ is achieved, irrespective of seasonal temperature fluctuations. The FRDA is also distinguishable by its compact machine design. The technology is therefore suitable for container installations and where little space is available. In comparison with conventional adsorption dryers, not much maintenance is required.
