BOGE FRDA refrigeration-adsorption dryers

The FRDA series dehumidifiers are an innovative combination of two techniques - refrigeration and adsorption drying. The "tandem technology" ensures stable outlet pressure dew points, while at the same time having higher energy efficiency values than other compressed air drying methods: FRDA uses less air, desiccant and energy, and operating and maintenance costs are low, which translates into overall savings .

Entering the desired dew point value on the tandem dryer controller allows you to quickly switch between the pressure dew point of the refrigerant dryer and the adsorption dryer. The FRDA, with a significantly lower proportion of regenerative air, keeps the selected dew point constant from -70 ° C to
