Modular dessicant air dryers
ECOTROC DDAP DESICCANT DRYERS HEATLESS REGENERATED
KSI
Pressure dew point down to -40°F
Capacity up to 130 scfm
Desiccant dryers are used in environments where a specified pressure dew point of -40°F to -94°F must be reliable and safe. Dryers of the ECOTROC DD series are available in three versions: as a compact aluminum series (DDAP) for volume flows up to 110 cfm, with welded vessels (DDN) for volume flows up to 705 cfm as well as in the large version (DDF) up to 1800 cfm*. Higher volume flows are available on request.
Advantages
The ECOTROC DDAP Plus-Effects
- Change of desiccant via filling and emptying openings
- Filling nozzles eliminate the need for laborious removal of the plates
- Simple and clear service packages
- Easy to understand control unit, simple menu navigation (with ETC 4.0)
- The two service blocks on the upper and lower plate contain all the parts required for service. After simple disassembly, all service work is carried out in a relaxed posture, eliminating the need for laborious work directly on the dryer. Important: The dryer remains installed in the overall installationrn
