B-KOOL

SIGNIFICANTLY LONGER FILTER CARTRIDGE LIFE
B-KOOL Refrigeration Dryer cools the compressed air and separates out most of the moisture,
collecting it in the B-KOOL and thus preventing it from passing into the filter cartridge.
Particularly in environments with high ambient temperatures, the B-KOOL refrigeration dryer extends filter
capacity to an outstanding extent.

The B-KOOL is available in three versions:

• B-KOOL II 680i: Integrated solution in a new design for MINI-VERTICUS and VERTICUS in Super Silent version
• B-KOOL 680i: Integrated solution for PE-VE in Super Silent version
• B-KOOL 680s: As a standalone solution for compressors with a P 41 or P 61 purification system

HOW THE B-KOOL REFRIGERATION DRYER WORKS

1. The air saturated with moisture is fed out of the final separator of the compressor into the B-KOOL refrigeration dryer.
2. In the high-efficiency cooling unit, the temperature of the compressed air, and thus its pressure dew-point, are
   reduced to approx. 3°C. For reasons of physics, the cooled air is no longer able to store the moisture content and the oil and water vapour condenses.
3. The condensate is collected in the integrated separator and thus does not enter the filter cartridge.
4. The condensate is discharged into the compressor unit‘s collecting container via the automatic condensate drain.
5. The cooled and dried air is fed into the purification system by the B-KOOL refrigeration dryer.
6. The B-KOOL control monitors the function of the integrated cooling technology and controls the condensate drain valve of the automatic condensate drain.
